Subject: [PATCH 002/869] ns9xxx: fix handle_prio_irq to unmask irqs with lower
 priority
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an irq is reported all lower prio irqs are masked until the current
irq is acked.  So never leave handle_prio_irq without acking.

desc->status & IRQ_INPROGRESS should never become true because the current
irq is masked until it is acked, too.

From fa3959f457109cc7d082b86ea6daae927982815b Mon Sep 17 00:00:00 2001

Subject: [PATCH 011/869] mv643xx_eth: get rid of static variables, allow
 multiple instances

Move mv643xx_eth's static state (ethernet register block base address
and MII management interface spinlock) into a struct hanging off the
shared platform device.  This is necessary to support chips that
contain multiple mv643xx_eth silicon blocks.

Subject: [PATCH 012/869] mv643xx_eth: mbus decode window support

Make it possible to pass mbus_dram_target_info to the mv643xx_eth
driver via the platform data, and make the mv643xx_eth driver
program the window registers based on this data if it is passed in.

Make t_clk configurable via platform device data (with the current
hardcoded value, 133 MHz, being the default), as it varies across

Change the MV643XX_ETH_SHARED_NAME platform driver name to something
shorter than 19 characters, so that we can register multiple (otherwise
we end up with sysfs conflicts since all instances will map to
"mv643xx_eth_shared." as there is a 20-char sysfs file name limit.)

Subject: [PATCH 015/869] mv643xx_eth: inter-mv643xx SMI port sharing

There exist chips with up to four mv643xx_eth silicon blocks but
only one external SMI (MII management) interface -- the SMI logic
of the first block is shared by all the blocks.

Handle this by allowing a per-port override of which
mv643xx_eth_shared's SMI registers (and spinlock) to use.

Subject: [PATCH 018/869] sch_htb: remove from event queue in
 htb_parent_to_leaf()

There is lack of removing a class from the event queue while changing
from parent to leaf which can cause corruption of this rb tree. This
patch fixes a bug introduced by my patch: "sch_htb: turn intermediate
classes into leaves" commit: 160d5e10f87b1dc88fd9b84b31b1718e0fd76398.

Many thanks to Jan 'yanek' Bortl for finding a way to reproduce this
rare bug and narrowing the test case, which made possible proper
diagnosing.

This patch is recommended for all kernels starting from 2.6.20.

Subject: [PATCH 025/869] niu: Fix probing regression for maramba on-board
 chips.

Changeset 7f7c4072ea552f97a0898331322f71986a97299c ("niu: Determine
the # of ports from the card's VPD data") caused maramba on-board
NIU ports to stop probing properly.

The old code had a fallback that would use a num_ports value of
4 if all the probing methods failed, but that was removed.

This restores the fallback of 4 ports, to get things working
again.

Bump driver version and release date.

Subject: [PATCH 027/869] [ARM] 5024/1: Fix some minor clk issues in the MMCI
 PL18x driver

This fixes some two minor clk issues.

The first is a comparison where a byte will probably wrap around to 0 instead of being saturated to 255, shouldn't be triggered very often but need fixing.

The second is an attempt by the driver to adjust MCLK down to the maximum frequency according to the spec, so we don't accidentally overclock the PL18x block. None of the mach-{versatile|integrator|lh7a40x} that use it in-tree seem to have a problem with this (all are well below 100MHz, typically 33MHz), but some day there will be a problem.

This is not applied on top of the earlier mmci patch for race condition but rather a clean 2.6.25, but I guess it applies without major protests anyway.

Subject: [PATCH 028/869] [ARM] 5027/1: Fixed random memory corruption on pxa
 suspend cycle.

Each time a pxa type cpu went in suspend, a portion of
kmalloc memory was corrupted.
The issue was an incorrect length allocation introduced by
the commit 711be5ccfe9a02ba560aa918a008c31ea4760163 for
the save registers array (=> overflow).

Subject: [PATCH 031/869] mac80211: Do not free net device after it is
 unregistered.

The error path in ieee80211_register_hw() may call the unregister_netdev()
and right after it - the free_netdev(), which is wrong, since the
unregister releases the device itself.

So the proposed fix is to NULL the local->mdev after unregister is done
and check this before calling free_netdev().

I checked - no code uses the local->mdev after unregister in this error
path (but even if some did this would be a BUG).

Subject: [PATCH 034/869] [POWERPC] cell: Fix lost interrupts due to fasteoi
 handler

We may currently lose interrupts during SPE context switch, as we alter
the INT_Route register. Because the IIC uses a per-thread priority
status, changing the interrupt routing to a different thread means that
the IRQ is no longer masked by the priority status, so we end up with
two fasteoi IRQ handlers executing for the one irq_desc. The fasteoi
handler doesn't handle multiple IRQs, so drops the second one.

Fix this by using our own flow handler. This is based on
handle_edge_irq, but issues an eoi after IRQs are handled, and doesn't
do any mask/unmasking.

 purging DMA queue

When we issue a MFC purge request, we may inadvertantly clear the
suspended status.

This change adds the MFC_CNTL_SUSPEND_MASK when we issue a purge
request, so that the suspend bit is masked out.

Subject: [PATCH 036/869] [POWERPC] spufs: fix save of mfc_cntl register

Currently, we can introduce invalid entries into the MFC queues:

1) context starts a DMA

2) context gets scheduled out during a DMA
  - kernel saves MFC queue to CSA
  - kernel saves 0x0 in csa->mfc_control_RW

3) context gets scheduled in
  - csa->mfc_control[Q] ('queues empty') isn't set, so DMA queues are
    restored from the CSA

4) context's DMA is completed

5) context gets scheduled out again, no DMA occuring this time
  - kernel sees that MFC_CNTL[Q] ('queues empty') is set, so doesn't
    touch saved queue data in CSA
  - kernel saves 0x0 in csa->mfc_control_RW

6) context gets scheduled in
  - csa->mfc_control[Q] ('queues empty') isn't set (we saved is as 0!),
    so DMA queues are restored from the CSA

In this last restore, we've restored the queue status from step 2,
which are now invalid.

This change makes save_mfc_cntl() closer to the save/restore sequence,
as specified in the CBE handbook.

With changes from Luke Browning.

Subject: [PATCH 037/869] [POWERPC] spufs: fix post-stopped update of MFC_CNTL
 register

We currently have two issues with the MFC save code:

 * save_mfc_decr doesn't handle a transition of 1 -> 0 of the Ds bit
 * The Q bit may be stale in the CSA

This change fixes the first issue by clearing the relevant bits from
the MFC_CNTL value in the CSA before or-ing in the updated status.
Also, we add the Q bit to the updated status.

 lock held

Currently, we update the SPU master run control bit (ie,
spu_enable_spu) in spufs_run_spu before we grab the context mutex. This
can result in races with other processes accessing this context's
resources.

This change moves the spu_enable_spu to after we have acquired the
context lock.

There's currently no way to tell if spu_process_callback has

by either the syscall or the spu_acquire fail case.

Instead, just do a non-interruptible mutex_lock here.

synchronize_irq() provides the serialization for
SPU_CONTEXT_SWITCH_PENDING which is read with a simple load. This
routine guarantees that the relevant interrupt handlers are not running,
so that the next time they do run they will see the update
memory value.

This must be done correctly so that exception handling code does not
restart the mfc in the middle of a context switch while we are trying
to atomically stop it and save state.

Subject: [PATCH 041/869] [POWERPC] spufs: try to route SPU interrupts to local
 node

Currently, we re-route SPU interrupts to the current cpu, which may be
on a remote node. In the case of time slicing, all spu interrupts will
end up routed to the same cpu, where the spusched_tick occurs.

This change routes mfc interrupts to the cpu where the controlling
thread last ran, provided that cpu is on the same node as the spu
(otherwise don't reroute interrupts).

This should improve performance and provide a more predictable
environment for processing spu exceptions. In the past we have seen
concurrent delivery of spu exceptions to two cpus. This eliminates that
concern.

SPU class 0 & 1 exceptions may occur in parallel, so we may end up
overwriting csa.dsisr.

This change adds dedicated fields for each class to the spu and the spu
context so that fault data is not overwritten.

Subject: [PATCH 043/869] [POWERPC] spufs: handle faults while the context
 switch pending flag is set

Currently, page fault handlers don't issue a mfc restart if the context
switch pending flag is set, which can leave us with a hanging DMA after
a context restore.

This patch introduces fault pending flag that is set by the fault
handler and read by the context switch code, so that the latter can add
the restart bit at the right spot, after it has successfuly saved the
state of the mfc control register.

Subject: [PATCH 045/869] ip: Use inline function dst_metric() instead of
 direct access to dst->metric[]

There are functions to refer to the value of dst->metric[THE_METRIC-1]
directly without use of a inline function "dst_metric" defined in
net/dst.h.

The following patch changes them to use the inline function
consistently.

x86.git testing found the following build failure in latest -git:

 drivers/built-in.o:nsc-ircc.c:(.text+0xdf266): more undefined references to `pnp_get_resource' follow
 make: *** [.tmp_vmlinux1] Error 1

triggered via this config:

  http://redhat.com/~mingo/misc/config-Sat_May__3_20_53_13_CEST_2008.bad

while generally most users will have PNP enabled, drivers can support
non-PNP build mode too - and most drivers implement it. That is typically
done by providing a dummy pnp_driver structure that will not probe anything.

The fallback routines in the driver will handle this dumber mode of
operation too.

This patch implements that. I have not tested whether this actually
works on real hardware so take care. It does resolve the build bug.

[ Another solution that is used by a few drivers is to exclude the driver
  in the Kconfig if PNP is disabled, via "depends on PNP", but this would
  limit the availability of the driver needlessly. ]

Subject: [PATCH 049/869] irda: fix !PNP support for
 drivers/net/irda/smsc-ircc2.c

x86.git testing found this build bug on v2.6.26-rc1:

  ERROR: "pnp_get_resource" [drivers/net/irda/smsc-ircc2.ko] undefined!
  make[1]: *** [__modpost] Error 1
  make: *** [modules] Error 2

the driver did not anticipate the case of !CONFIG_PNP which is rare but
still possible. Instead of restricting the driver to PNP-only in the
Kconfig space, add the (trivial) dummy struct pnp_driver - this is that
other drivers use in the !PNP case too.

The driver itself can in theory be initialized on !PNP too in certain
cases, via smsc_ircc_legacy_probe().

Patch only minimally build tested, i dont have this hardware.

Subject: [PATCH 051/869] sparc64: remove online_page()

The identical online_page() implementations from all architectures got
moved to mm/memory_hotplug.c - except for the sparc64 one that even was
dead code due to MEMORY_HOTPLUG not being available there.

dccp_feat_change() validates length and on error is returning 1.
This happens to work since call chain is checking for 0 == success,
but this is returned to userspace, so make it a real error value.

This reverts commit 65e4113684e50cee75357ce10dc9026b0929e4e9.

Unlike the other cases Pavel fixed, this case did not
setup a netdev->destructor of free_netdev, therefore this
change was not correct.

Subject: [PATCH 057/869] libata: improve post-reset device ready test

Some controllers (jmb and inic162x) use 0x77 and 0x7f to indicate that
the device isn't ready yet.  It looks like they use 0xff if device
presence is detected but connection isn't established.  0x77 or 0x7f
after connection is established and use the value from signature FIS
after receiving it.

This patch implements ata_check_ready(), which takes TF status value
and determines whether the port is ready or not considering the above
and other conditions, and use it in @check_ready() functions.  This is
safe as both 0x77 and 0x7f aren't valid ready status value even though
they have BSY bit cleared.

This fixes hot plug detection failures which can be triggered with
certain drives if they aren't already spun up when the data connector
is hot plugged.

Tested on sil, sil24, ahci (jmb/ich), piix and inic162x combined with
eight drives from all major vendors.

Subject: [PATCH 058/869] ata_piix: verify SIDPR access before enabling it

On certain configurations (certain macbooks), even though all the
conditions for SIDPR access described in the datasheet are met,
actually reading those registers just returns 0 and have no effect on
write.  Verify SIDPR is actually working before enabling it.

This is reported by Ryan Roth in bz#10512.

Subject: [PATCH 060/869] [POWERPC] 4xx: Fix problem with new TLB storage
 attibute fields on 440x6 core

The new 440x6 core used on AMCC 460EX/GT introduces new storage attibure
fields to the TLB2 word. Those are:

Bit  11   12   13   14   15
     WL1  IL1I IL1D IL2I IL2D

With these bits the cache (L1 and L2) can be configured in a more flexible
way, instruction- and data-cache independently now. The "old" I and W bits
are still available and setting these old bits will automically set these
new bits too (for backward compatibilty).

The current code does not clear these fields resulting in disabling the cache
by chance. This patch now makes sure that these new bits are cleared when
the TLB2 word is written.

Subject: [PATCH 061/869] sata_mv more cosmetic changes

More cosmetic changes; no code changes.

 -- try and improve consistency of naming.
 -- add missing _OFS to tails of register offset definitions.
 -- rename mv_setup_ifctl() to mv_setup_ifcfg(), since that's what it really does.
 -- remove/move some dead comments

Subject: [PATCH 062/869] sata_mv pci features

Some of the GenIIe EDMA optimizations should not be used
for non-PCI (SOC) devices, and nor for certain configurations
of conventional PCI (non PCI-X, PCIe) buses.

Logic taken/simplified from that in the Marvell proprietary driver.

Subject: [PATCH 063/869] sata_mv wait for empty+idle

When performing EH, it is recommended to wait for the EDMA engine
to empty out requests-in-progress before disabling EDMA.

Introduce code to poll the EDMA_STATUS register for idle/empty bits
before disabling EDMA.  For non-EH operation, this will normally exit
without delay, other than the register read.

A later series of patches may focus on eliminating this and various
other register reads (when possible) throughout the driver,
but for now we're focussing on solid reliablity.

Subject: [PATCH 064/869] sata_mv new mv_qc_defer method

The EDMA engine cannot tolerate a mix of NCQ/non-NCQ commands,
and cannot be used for PIO at all.  So we need to prevent libata
from trying to feed us such mixtures.

Introduce mv_qc_defer() for this purpose, and use it for all chip versions.

Rearrange mv_config_fbs() to more closely follow the (corrected) datasheet
recommendations for NCQ and FIS-based switching (FBS).

Also, maintain a port flag to let us know when FBS is enabled.
We will make more use of that flag later in this patch series.

Subject: [PATCH 067/869] sata_mv NCQ and SError fixes for mv_err_intr

Sigh.  Undo some earlier changes to mv_port_intr(),
so that we now read/clear SError again in all cases.

Arrange the top of the function to be as close as possible
to what we need for a later update (in this series) for ERR_DEV handling.

Fix things so that libata-eh can attempt a READ_LOG_EXT_10H
in response to a failed NCQ command, by just doing a local
mv_eh_freeze() rather than ata_port_freeze().

This will now fully handle NCQ errors much of the time,
but more fixes are needed for FBS/PMP, and for certain chip errata.

Subject: [PATCH 071/869] sata_mv delayed eh handling

Introduce a new "delayed error handling" mechanism in sata_mv,
to enable us to eventually deal with multiple simultaneous NCQ
failures on a single host link when a PM is present.

This involves a port flag (MV_PP_FLAG_DELAYED_EH) to prevent new
commands being queued, and a pmp bitmap to indicate which pmp links
had NCQ errors.

The new mv_pmp_error_handler() uses those values to invoke
ata_eh_analyze_ncq_error() on each failed link, prior to freezing
the port and passing control to sata_pmp_error_handler().

This is based upon a strategy suggested by Tejun.

For now, we just implement the delayed mechanism.
The next patch in this series will add the multiple-NCQ EH code
to take advantage of it.

multiple failed links on a port-multiplier when using NCQ.

To do this, we clear the ERR_DEV bit in the EDMA Halt-Conditions register,
so that the EDMA engine doesn't self-disable on the first NCQ error.

Our EH code sets the MV_PP_FLAG_DELAYED_EH flag to prevent new commands
being queued while we await completion of all outstanding NCQ commands
on all links of the failed PM.

The SATA Test Control register tells us which links have failed,
so we must only wait for any other active links to finish up
before we stop the EDMA and run the .error_handler afterward.

The patch also includes skeleton code for handling of non-NCQ FBS operation.
This is more for documentation purposes right now, as that mode is not yet
enabled in sata_mv.

Subject: [PATCH 073/869] sata_mv use hweight16() for bit counting (V2)

Some tidying as suggested by Grant Grundler.

Nuke local bit-counting function from sata_mv in favour of using hweight16().
Also add a short explanation for the 15msec timeout used when waiting for empty/idle.

Subject: [PATCH 076/869] sata_inic162x: update TF read handling

inic162x can't reliably read back TF or at least we don't know how to
do it yet.  The only values which seem reliable are status and error.
This patch updates access to TF.

* implement inic_tf_read() which reads the TF area in mmio area

* implement custom inic_qc_fill_rtf() which only returns true if
  status indicates device error.  it'll be returning bogus addresses
  for device errors but it'll be able to report why it failed at
  least.

* implement custom inic_check_ready() and use ata_wait_after_reset()
  instead of the SFF version.

* use inic_tf_read() for classification.

This is not perfect but it fixes hotplug detection failure and at
least makes the driver report 0's instead of random garbages while
reporting valid status and error for device errors.

Subject: [PATCH 077/869] sata_inic162x: use IDMA for ATA_PROT_DMA

The modified driver on initio site has enough clue on how to use IDMA.
Use IDMA for ATA_PROT_DMA.

* LBA48 now works as long as it uses DMA (LBA48 devices still aren't
  allowed as it can destroy data if PIO is used for any reason).

* No need to mask IRQs for read DMAs as IDMA_DONE is properly raised
  after transfer to memory is actually completed.  There will be some
  spurious interrupts but host_intr will handle it correctly and
  manipulating port IRQ mask interacts badly with the other port for
  some reason, so command type dependent port IRQ masking is not used
  anymore.

Subject: [PATCH 079/869] sata_inic162x: use IDMA for non DMA ATA commands

Use IDMA for PIO and non-data commands.  This allows sata_inic162x to
safely drive LBA48 devices.  Kill inic_dev_config() which contains
code to reject LBA48 devices.

With this change, status checking in inic_qc_issue() to avoid hard
lock up after hotplug can go away too.

Subject: [PATCH 080/869] sata_inic162x: use IDMA for ATAPI commands

Use IDMA for ATAPI commands.  Write and some misc commands time out
when executed using ATAPI_PROT_DMA but ATAPI_PROT_PIO works fine.  As
PIO is driven by DMA too, it doesn't make any noticeable difference
for native SATA devices.  inic_check_atapi_dma() is implemented to
force PIO for those ATAPI commands.

After this change, sata_inic162x issues all commands using IDMA.

Subject: [PATCH 081/869] sata_inic162x: kill now unused SFF related stuff

sata_inic162x now doesn't use any SFF features.  Remove all SFF
related stuff.

* Mask unsolicited ATA interrupts.  This removes our primary source of
  spurious interrupts and spurious interrupt handling can be tightened
  up.  There's no need to clear ATA interrupts by reading status
  register either.

* Don't dance with IDMA_CTL_ATA_NIEN and simplify accesses to
  IDMA_CTL.

* Inherit from sata_port_ops instead of ata_sff_port_ops.

* Don't initialize or use ioaddr.  There's no need to map BAR0-4
  anymore.

Subject: [PATCH 084/869] pata_atiixp: Don't disable

A couple of distributions (Fedora, Ubuntu) were having weird problems with the
ATI IXP series PATA controllers being reported as simplex.  At the heart of
the problem is that both distros ignored the recommendations to load pata_acpi
and ata_generic *AFTER* specific host drivers.

The underlying cause however is that if you D3 and then D0 an ATI IXP it
helpfully throws away some configuration and won't let you rewrite it.

Add checks to ata_generic and pata_acpi to pin ATIIXP devices.  Possibly the
real answer here is to quirk them and pin them, but right now we can't do that
before they've been pcim_enable()'d by a driver.

I'm indebted to David Gero for this.  His bug report not only reported the
problem but identified the cause correctly and he had tested the right values
to prove what was going on

[If you backport this for 2.6.24 you will need to pull in the 2.6.25
removal of the bogus WARN_ON() in pcim_enagle]

If the call to bond_create_sysfs_entry in bond_create fails, the

Otherwise - kernel BUG at net/core/dev.c:4057!

Checked with artificial failures injected into bond_create_sysfs_entry.

Pavel's original patch modified by Jay Vosburgh to move code around
for clarity (remove goto-hopping within the unwind block).

Date: Fri, 2 May 2008 17:49:39 -0700
Subject: [PATCH 087/869] bonding: Deadlock between bonding_store_bonds and
 bond_destroy_sysfs.

The sysfs layer has an internal protection, that ensures, that
all the process sitting inside ->sore/->show callback exits
before the appropriate entry is unregistered (the calltraces
are rather big, but I can provide them if required).

On the other hand, bonding takes rtnl_lock in
a) the bonding_store_bonds, i.e. in ->store callback,
b) module exit before calling the sysfs unregister routines.

Thus, the classical AB-BA deadlock may occur. To reproduce run
# while :; do modprobe bonding; rmmod bonding; done
and
# while :; do echo '+bond%d' > /sys/class/net/bonding_masters ; done
in parallel.

The fix is to move the bond_destroy_sysfs out of the rtnl_lock,
but _before_ bond_free_all to make sure no bonding devices exist
after module unload.

Subject: [PATCH 088/869] bonding: fix enslavement error unwinds

	As part of:

commit c2edacf80e155ef54ae4774379d461b60896bc2e
Author: Jay Vosburgh <fubar@us.ibm.com>
Date:   Mon Jul 9 10:42:47 2007 -0700

    bonding / ipv6: no addrconf for slaves separately from master

two steps were rearranged in the enslavement process: netdev_set_master
is now before the call to dev_open to open the slave.

	This patch updates the error cases and unwind process at the
end of bond_enslave to match the new order.  Without this patch, it is
possible for the enslavement to fail, but leave the slave with IFF_SLAVE
set in its flags.

Subject: [PATCH 089/869] gianfar: Fix a locking bug in gianfar's sysfs code

During sparse cleanup, found a locking bug.  Some of the sysfs functions were
acquiring a lock, and then returning in the event of an error.  We rearrange
the code so that the lock is released in error conditions, too.

Subject: [PATCH 091/869] ucc_geth: Fix a bunch of sparse warnings

ucc_geth didn't have anything marked as __iomem.  It was also inconsistent
with its use of in/out accessors (using them sometimes, not using them other
times).  Cleaning this up cuts the warnings down from hundreds to just over a
dozen.

Subject: [PATCH 092/869] uli526x: initialize the hardware prior to requesting
 interrupts

The firmware on MPC8610HPCD boards enables ULI ethernet and leaves it
in some funky state before booting Linux. For drivers, it's always good
idea to (re)initialize the hardware prior to requesting interrupts.

This patch fixes the following oops:

Subject: [PATCH 093/869] uli526x: fix endianness issues in the setup frame

This patch fixes uli526x driver's issues on a PowerPC boards: uli chip
is unable to receive the packets.

It appears that send_frame_filter prepares the setup frame in the
endianness unsafe manner. On a big endian machines we should shift
the address nibble by two bytes.

Subject: [PATCH 094/869] e1000e: Add support for BM PHYs on ICH9

This patch adds support for the BM PHY, a new PHY model being used
on ICH9-based implementations.

This new PHY exposes issues in the ICH9 silicon when receiving
jumbo frames large enough to use more than a certain part of the
Rx FIFO, and this unfortunately breaks packet split jumbo receives.
For this reason we re-introduce (for affected adapters only) the
jumbo single-skb receive routine back so that people who do
wish to use jumbo frames on these ich9 platforms can do so.
Part of this problem has to do with CPU sleep states and to make
sure that all the wake up timings are correctly we force them
with the recently merged pm_qos infrastructure written by Mark
Gross. (See http://lkml.org/lkml/2007/10/4/400).

To make code read a bit easier we introduce a _IS_ICH flag so
that we don't need to do mac type checks over the code.

Subject: [PATCH 096/869] 3c980-TX needs EXTRA_PREAMBLE

The ethernet card 3c980-TX needs a mdio_sync() to initialize the ethernet
properly. This is forced by adding an EXTRA_PREAMBLE to its drv_flags.

Without this, the driver did not reconnect after a link loss.

Subject: [PATCH 098/869] [netdrvr] eexpress: IPv6 fails - multicast problems

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577

I was unable to access a computer containing an Intel EtherExpress 16 network
card using IPv6.

I traced this to failure of neighbour discovery.  When I used an "ip -6 neigh
add" command, on the computer attempting access, to insert a binding between
the IPv6 address of the computer with the Intel EtherExpress 16 network card
and the card's ethernet address, I was able to access that computer using
IPv6.

Neighbour discovery requires working multicast.  The driver sources file
eexpress.c contains an approximately 30 line function eexp_setup_filter used
when loading multicast addresses.

I found 3 problems in this function

1) It wrote the number of multicast addresses to the card instead of the
    number of bytes in the multicast addresses.

2) When loading multiple multicast addresses it loaded the first one
    provided multiple times instead of loading each one once.

3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the
    test for the error situation of 'dmi' being NULL.

Correcting these problems allows the computer with the Intel EtherExpress 16
network card to found by IPv6 neighbour discovery.

p.s. There is some information on the Intel EtherExpress 16 at
http://www.intel.com/support/etherexpress/vintage/sb/cs-013500.htm

	Reload new firmware
	Wait..
	Firmware patches kernel

So it should be CAY_SYS_RAWIO - not that I suspect this is in fact a
credible attack vector!

Subject: [PATCH 104/869] [POWERPC] 4xx: Add endpoint support to 4xx PCIe
 driver

This patch adds basic endpoint support to the 4xx PCIe driver.

This is done by checking the device_type property of the PCIe
device node ("pci" for root-complex and "pci-endpoint" for endpoint
configuration).

Note: Currently we map a fixed 64MByte window to PLB address 0 (SDRAM).
This should probably be configurable via a dts property.

Subject: [PATCH 105/869] [POWERPC] 4xx: Fix PCI mem in sequoia DTS

This patch is fixes the sequoia.dts device tree file to use the values defined
in the 440Epx data sheet from AMCC.

That fixes an issue where some devices, including graphics cards, would not
initialize properly because the PCI resource space was not big enough.

Subject: [PATCH 106/869] [PATCH] fix reservation discarding in affs

- remove affs_put_inode, so preallocations aren't discared unnecessarily
  often.
- remove affs_drop_inode, it's called with a spinlock held, so it can't
  use a mutex.
- make i_opencnt atomic
- avoid direct b_count manipulations
- a few allocation failure fixes, so that these are more gracefully
  handled now.

Subject: [PATCH 107/869] [PATCH] kill ->put_inode

And with that last patch to affs killing the last put_inode instance we
can finally, after many years of transition kill this racy and awkward

(It's kinda funny that even the description in
Documentation/filesystems/vfs.txt was entirely wrong..)

Also remove a very misleading comment above the defintion of
struct super_operations.

Subject: [PATCH 108/869] [PATCH] fix SMP ordering hole in fcntl_setlk()

fcntl_setlk()/close() race prevention has a subtle hole - we need to
make sure that if we *do* have an fcntl/close race on SMP box, the
access to descriptor table and inode->i_flock won't get reordered.

As it is, we get STORE inode->i_flock, LOAD descriptor table entry vs.
STORE descriptor table entry, LOAD inode->i_flock with not a single
lock in common on both sides.  We do have BKL around the first STORE,
but check in locks_remove_posix() is outside of BKL and for a good
reason - we don't want BKL on common path of close(2).

Solution is to hold ->file_lock around fcheck() in there; that orders
us wrt removal from descriptor table that preceded locks_remove_posix()
on close path and we either come first (in which case eviction will be
handled by the close side) or we'll see the effect of close and do
eviction ourselves.  Note that even though it's read-only access,
we do need ->file_lock here - rcu_read_lock() won't be enough to
order the things.

Subject: [PATCH 109/869] x86: fix PAE pmd_bad bootup warning

Fix warning from pmd_bad() at bootup on a HIGHMEM64G HIGHPTE x86_32.

That came from 9fc34113f6880b215cbea4e7017fc818700384c2 x86: debug pmd_bad();
but we understand now that the typecasting was wrong for PAE in the previous
version: pagetable pages above 4GB looked bad and stopped Arjan from booting.

And revert that cded932b75ab0a5f9181ee3da34a0a488d1a14fd x86: fix pmd_bad
and pud_bad to support huge pages.  It was the wrong way round: we shouldn't
weaken every pmd_bad and pud_bad check to let huge pages slip through - in
part they check that we _don't_ have a huge page where it's not expected.

Put the x86 pmd_bad() and pud_bad() definitions back to what they have long
been: they can be improved (x86_32 should use PTE_MASK, to stop PAE thinking
junk in the upper word is good; and x86_64 should follow x86_32's stricter
comparison, to stop thinking any subset of required bits is good); but that
should be a later patch.

Fix Hans' good observation that follow_page() will never find pmd_huge()
because that would have already failed the pmd_bad test: test pmd_huge in
between the pmd_none and pmd_bad tests.  Tighten x86's pmd_huge() check?
No, once it's a hugepage entry, it can get quite far from a good pmd: for
example, PROT_NONE leaves it with only ACCESSED of the KERN_PGTABLE bits.

However... though follow_page() contains this and another test for huge
pages, so it's nice to keep it working on them, where does it actually get
called on a huge page?  get_user_pages() checks is_vm_hugetlb_page(vma) to
to call alternative hugetlb processing, as does unmap_vmas() and others.

Subject: [PATCH 112/869] RDMA/cxgb3: Don't add PBL memory to gen_pool in
 chunks

Current iw_cxgb3 code adds PBL memory to the driver's gen_pool in 2 MB
chunks.  This limits the largest single allocation that can be done to
the same size, which means that with 4 KB pages, each of which takes 8
bytes of PBL memory, the largest memory region that can be allocated
is 1 GB (256K PBL entries * 4 KB/entry).

Remove this limit by adding all the PBL memory in a single gen_pool
chunk, if possible.  Add code that falls back to smaller chunks if
gen_pool_add() fails, which can happen if there is not sufficient
contiguous lowmem for the internal gen_pool bitmap.

Subject: [PATCH 116/869] [CIFS] cleanup cifsd completion

Was a holdover from the old kernel_thread based cifsd
code. We needed to know that the thread had set the task variable
before proceeding. Now that kthread_run returns the new task, this
doesn't appear to be needed anymore.

As best I can tell, this sleep was intended to try to prevent
cifs_umount from freeing the cifsSesInfo struct before cifsd had
exited. Now that cifsd is using the kthread API, we know that
when kthread_stop returns that cifsd has exited, so I don't
think this is needed any longer.

Subject: [PATCH 117/869] RDMA/cxgb3: Fix severe limit on userspace memory
 registration size

Currently, iw_cxgb3 is severely limited on the amount of userspace
memory that can be registered in in a single memory region, which
causes big problems for applications that expect to be able to
register 100s of MB.

The problem is that the driver uses a single kmalloc()ed buffer to
hold the physical buffer list (PBL) for the entire memory region
during registration, which means that 8 bytes of contiguous memory are
required for each page of memory being registered.  For example, a 64
MB registration will require 128 KB of contiguous memory with 4 KB
pages, and it unlikely that such an allocation will succeed on a busy
system.

This is purely a driver problem: the temporary page list buffer is not
needed by the hardware, so we can fix this by writing the PBL to the
hardware in page-sized chunks rather than all at once.  We do this by
splitting the memory registration operation up into several steps:

 - Allocate PBL space in adapter memory for the full registration
 - Copy PBL to adapter memory in chunks
 - Allocate STag and enable memory region

This also allows several other cleanups to the __cxio_tpt_op()
interface and related parts of the driver.

This change leaves the reregister memory region and memory window
operations broken, but they already didn't work due to other
longstanding bugs, so fixing them will be left to a later patch.

Subject: [PATCH 118/869] Revert "uml: fix gcc problem"

This reverts commit 22eecde2f9034764a3fd095eecfa3adfb8ec9a98.  Uli
reports that it breaks UML on x86-64 with the Fedora 8 gcc (gcc 4.1.2),
causing a crash on startup. See

	http://marc.info/?l=linux-kernel&m=121011722806093&w=2

for a trace.

Subject: [PATCH 119/869] Revert "drm/vbl rework: rework how the drm deals with
 vblank."

This reverts commit ac741ab71bb39e6977694ac0cc26678d8673cda4.

Okay this looks like wasn't as fully baked as I'd led myself to believe.

Revert for now for further baking.

Subject: [PATCH 131/869] [Blackfin] arch: fix gdb testing regression

When transferring to IRQ5 from an exception, save SYSCFG in memory across the
transfer and clear the trace bit.

When we get a single step exception, check whether we can safely clear the
trace bit in SYSCFG.  We can (and should) clear it after the first instruction
of the interrupt handler; the first insn saves SYSCFG to the stack in all
handlers.

Subject: [PATCH 141/869] [Blackfin] arch: remove useless IRQ_SW_INT defines

IRQ_SW_INT1 and IRQ_SW_INT2 obsolete:
Remove useless defines
Fix SYS_IRQS
Keep numbering scheme, so we don't break existing configurations.

Concurrency isn't a big deal here since we have requests in flight
at this point, but do the locked variant to set a better example.

Subject: [PATCH 145/869] [S390] s390: Optimize user and work TIF check

On return from syscall or interrupt, we have to check if we return to
userspace (likely) and if there is work todo (less likely) to decide
if we handle the work. We can optimize this check: we first check for
the less likely work case and then check for userspace.

This patch is also a preparation for an additional patch, that fixes a bug
in KVM dealing with cpu bound guests.

Subject: [PATCH 146/869] [S390] s390-kvm: leave sie context on work. Removes
 preemption requirement

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

This patch fixes a bug with cpu bound guest on kvm-s390. Sometimes it
was impossible to deliver a signal to a spinning guest. We used
preemption as a circumvention. The preemption notifiers called
vcpu_load, which checked for pending signals and triggered a host
intercept. But even with preemption, a sigkill was not delivered
immediately.

This patch changes the low level host interrupt handler to check for the
SIE  instruction, if TIF_WORK is set. In that case we change the
instruction pointer of the return PSW to rerun the vcpu_run loop. The kvm
code sees an intercept reason 0 if that happens. This patch adds accounting
for these types of intercept as well.

The advantages:
- works with and without preemption
- signals are delivered immediately
- much better host latencies without preemption

From 139b83dd57248a3c8fcfb256e562311ad61478e9 Mon Sep 17 00:00:00 2001
From: Michael Ernst <mernst@de.ibm.com>
Date: Wed, 7 May 2008 09:22:54 +0200
Subject: [PATCH 147/869] [S390] cio: Remove cio_msg kernel parameter.

The only sporadically used CIO_DEBUG messages are replaced by ordinary
CIO_MSG_EVENT messages. The CIO_MSG_EVENT messages debug levels are
consolidated.

Subject: [PATCH 150/869] [S390] compat ptrace cleanup

This removes redundant arch code for generic ptrace requests
already handled by ptrace_request and compat_ptrace_request.
It simplifies things to just have the standard entry points,
and use the generic compat_sys_ptrace.

Subject: [PATCH 153/869] block: adjust tagging function queue bit locking

For most initialization purposes, calling blk_queue_init_tags() without
the queue lock held is OK. Only if called for resizing an existing map
must the lock be held. Ditto for tag cleanup, the maps are reference
counted.

So switch the general queue flag setting to the unlocked variant, but
retain the locked variant for resizing.

Subject: [PATCH 154/869] cfq-iosched: fix RCU race in the cfq io_context
 destructor handling

put_io_context() drops the RCU read lock before calling into cfq_dtor(),
however we need to hold off freeing there before grabbing and
dereferencing the first object on the list.

So extend the rcu_read_lock() scope to cover the calling of cfq_dtor(),
and optimize cfq_free_io_context() to use a new variant for
call_for_each_cic() that assumes the RCU read lock is already held.

Subject: [PATCH 155/869] vfs: splice remove_suid() cleanup

generic_file_splice_write() duplicates remove_suid() just because it
doesn't hold i_mutex.  But it grabs i_mutex inside splice_from_pipe()
anyway, so this is rather pointless.

Move locking to generic_file_splice_write() and call remove_suid() and
__splice_from_pipe() instead.

Subject: [PATCH 157/869] block: optimize generic_unplug_device()

Original patch from Mikulas Patocka <mpatocka@redhat.com>

Mike Anderson was doing an OLTP benchmark on a computer with 48 physical
disks mapped to one logical device via device mapper.

He found that there was a slowdown on request_queue->lock in function
generic_unplug_device. The slowdown is caused by the fact that when some
code calls unplug on the device mapper, device mapper calls unplug on all
physical disks. These unplug calls take the lock, find that the queue is
already unplugged, release the lock and exit.

With the below patch, performance of the benchmark was increased by 18%
(the whole OLTP application, not just block layer microbenchmarks).

So I'm submitting this patch for upstream. I think the patch is correct,
because when more threads call simultaneously plug and unplug, it is
unspecified, if the queue is or isn't plugged (so the patch can't make
this worse). And the caller that plugged the queue should unplug it
anyway. (if it doesn't, there's 3ms timeout).

Subject: [PATCH 159/869] udf: Fix memory corruption when fs mounted with
 noadinicb option

When UDF filesystem is mounted with noadinicb mount option, it
happens that we extend an empty directory with a block. A code in
udf_add_entry() didn't count with this possibility and used
uninitialized data leading to memory and filesystem corruption.
Add a check whether file already has some extents before operating
on them.

 stat code

get_part() is fairly expensive, as it O(N) loops over partitions
to find the right one. In lots of normal IO paths we end up looking
up the partition twice, to make matters even worse. Change the
stat add code to accept a passed in partition instead.

Subject: [PATCH 165/869] [CRYPTO] hmac: Avoid calling virt_to_page on key

When HMAC gets a key longer than the block size of the hash, it needs
to feed it as input to the hash to reduce it to a fixed length.  As
it is HMAC converts the key to a scatter and gather list.  However,
this doesn't work on certain platforms if the key is not allocated
via kmalloc.  For example, the keys from tcrypt are stored in the
rodata section and this causes it to fail with HMAC on x86-64.

This patch fixes this by copying the key to memory obtained via
kmalloc before hashing it.

Subject: [PATCH 170/869] IB/ipath: Return the correct opcode for RDMA WRITE
 with immediate

This patch fixes a bug in the RC responder which generates a completion
entry with the wrong opcode when an RDMA WRITE with immediate is received.

Subject: [PATCH 171/869] IB/ipath: Fix count of packets received by kernel

The loop in ipath_kreceive() that processes packets increments the
loop-index 'i' once too often, because the exit condition does not
depend on it, and is checked after the increment. By adding a check for
!last to the iterator in the for loop, we correct that in a way that is
not so likely to be re-broken by changes in the loop body.

Subject: [PATCH 172/869] IB/ipath: Need to always request and handle PIO avail
 interrupts

Now that we always use PIO for vl15 on 7220, we could get stuck forever
if we happened to run out of PIO buffers from the verbs code, because
the setup code wouldn't run; the interrupt was also ignored if SDMA was
supported.  We also have to reduce the pio update threshold if we have
fewer kernel buffers than the existing threshold.

Clean up the initialization a bit to get ordering safer and more
sensible, and use the existing ipath_chg_kernavail call to do init,
rather than doing it separately.

Drop unnecessary clearing of pio buffer on pio parity error.

Drop incorrect updating of pioavailshadow when exitting freeze mode
(software state may not match chip state if buffer has been allocated
and not yet written).

If we couldn't get a kernel buffer for a while, make sure we are
in sync with hardware, mainly to handle the exitting freeze case.

From ab69b3cf1219e0d07bb4ea373f36b1de38af531c Mon Sep 17 00:00:00 2001
From: John Gregor <john.gregor@qlogic.com>
Date: Wed, 7 May 2008 11:01:10 -0700
Subject: [PATCH 173/869] IB/ipath: Fix SDMA error recovery in absence of link
 status change

What's fixed:

    in ipath_cancel_sends()

        We need to unconditionally set ABORTING.  So, swap the tests
        so the set_bit() isn't shadowed by the &&.

        If we've disarmed the piobufs, then we need to unconditionally
        set DISARMED.  So, move it out from the overly protective if
        at the bottom.

    in sdma_abort_task()

        Abort_task was written knowing that the SDMA engine would always
        be reset (and restarted) on error.  A recent change broke that
        fundamental assumption by taking the restart portion and making
        it conditional on a link status change.  But, SDMA can go boom
        without a link status change in some conditions.

Commit 84f43c308b73a6a12128288721a1007ba4f1a8da "pxafb: introduce register
independent LCD connection type for pxafb" implements compatibility mode
for old style pxafb_mach_info initialization data wrongly, causing the
system to Oops repeatedly - first during probe, then when drawing. Fix it
and make pxafb_decode_mach_info void.

From 592eb9997dc89cd0c8f89a505e5348bbddce70f6 Mon Sep 17 00:00:00 2001
From: Robert Jarzmik <rjarzmik@free.fr>
Date: Wed, 7 May 2008 20:39:06 +0100
Subject: [PATCH 178/869] [ARM] 5032/1: Added cpufreq support for pxa27x CPU

PXA cpus maximum frequency depends on the cpu (624 for
pxa270, 520 for pxa272, 416 for pxa271). It should be
provided on kernel or module start (cpu-pxa
pxa27x_maxfreq parameter).

Make use of cpufreq_frequency_table_cpuinfo (patch by Bill
Reese provided by Philipp Zabel).

Some additionnal fixes from Philipp Zabel include :
 * rename PXA cpufreq driver to reflect added PXA27x support
 * remove unused variable ramstart from PXA cpufreq driver

Subject: [PATCH 180/869] sparc: Fix fork/clone/vfork system call restart.

We clobber %i1 as well as %i0 for these system calls,
because they give two return values.

Therefore, on error, we have to restore %i1 properly
or else the restart explodes since it uses the wrong
arguments.

This fixes glibc's nptl/tst-eintr1.c testcase.

Subject: [PATCH 181/869] sparc: Fix SA_ONSTACK signal handling.

We need to be more liberal about the alignment of the buffer given to
us by sigaltstack().  The user should not need to be mindful of all of
the alignment constraints we have for the stack frame.

This mirrors how we handle this situation in clone() as well.

Also, we align the stack even in non-SA_ONSTACK cases so that signals
due to bad stack alignment can be delivered properly.  This makes such
errors easier to debug and recover from.

Finally, add the sanity check x86 has to make sure we won't overflow
the signal stack.

This fixes glibc testcases nptl/tst-cancel20.c and
nptl/tst-cancelx20.c

Subject: [PATCH 188/869] sh: remove the broken SH_MPC1211 support

SH_MPC1211 has been marked as BROKEN for some time.

Unless someone is working on reviving it now, I'd therefore suggest this
patch to remove it.

- * NOTES about DMA transfers:
- *
- *  controller 1: channels 0-3, byte operations, ports 00-1F
- *  controller 2: channels 4-7, word operations, ports C0-DF
- *
- *  - ALL registers are 8 bits only, regardless of transfer size
- *  - channel 4 is not used - cascades 1 into 2.
- *  - channels 0-3 are byte - addresses/counts are for physical bytes
- *  - channels 5-7 are word - addresses/counts are for physical words
- *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
- *  - transfer count loaded to registers is 1 less than actual count
- *  - controller 2 offsets are all even (2x offsets for controller 1)
- *  - page registers for 5-7 don't use data bit 0, represent 128K pages
- *  - page registers for 0-3 use bit 0, represent 64K pages
- *
- * DMA transfers are limited to the lower 16MB of _physical_ memory.  
- * Note that addresses loaded into registers must be _physical_ addresses,
- * not logical addresses (which may differ if paging is active).
- *
- *  Address mapping for channels 0-3:
- *
- *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
- *    |  ...  |   |  ... |   |  ... |
- *    |  ...  |   |  ... |   |  ... |
- *    |  ...  |   |  ... |   |  ... |
- *   P7  ...  P0  A7 ... A0  A7 ... A0   
- * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
- *
- *  Address mapping for channels 5-7:
- *
- *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
- *    |  ...  |   \   \   ... \  \  \  ... \  \
- *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
- *    |  ...  |     \   \   ... \  \  \  ... \
- *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0   
- * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
- *
- * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
- * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
- * the hardware level, so odd-byte transfers aren't possible).
- *
- * Transfer count (_not # bytes_) is limited to 64K, represented as actual
- * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
- * and up to 128K bytes may be transferred on channels 5-7 in one operation.

From d58876e289b0153bf86162aa1a43249e0f0aa03d Mon Sep 17 00:00:00 2001
From: Magnus Damm <magnus.damm@gmail.com>
Date: Thu, 24 Apr 2008 21:36:34 +0900
Subject: [PATCH 211/869] sh: add interrupt ack code to sh3

This patch adds interrupt acknowledge code for external interrupt
sources on sh3 processors. Only really required for edge triggered
interrupts, but we ack regardless of sense configuration.

Clean up the intc tables by removing unneeded #ifdefs. The vector
list is what selects which interrupt sources that should be added,
having unsupported bitfields listed is ok as long as the vector
is excluded from the list.

We should not requeue the victim context in find_victim if the owner is
not in spu_run. It's first not needed because leaving the context on
the spu is an optimization and second is harmful because it means the
owner could re-enter spu_run when the context is on the runqueue and
trip the BUG_ON in __spu_update_sched_info.

Subject: [PATCH 218/869] tcp FRTO: SACK variant is errorneously used with
 NewReno
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Note: there's actually another bug in FRTO's SACK variant, which
is the causing failure in NewReno case because of the error
that's fixed here. I'll fix the SACK case separately (it's
a separate bug really, though related, but in order to fix that
I need to audit tp->snd_nxt usage a bit).

There were two places where SACK variant of FRTO is getting
incorrectly used even if SACK wasn't negotiated by the TCP flow.
This leads to incorrect setting of frto_highmark with NewReno
if a previous recovery was interrupted by another RTO.

An eventual fallback to conventional recovery then incorrectly
considers one or couple of segments as forward transmissions
though they weren't, which then are not LOST marked during
fallback making them "non-retransmittable" until the next RTO.
In a bad case, those segments are really lost and are the only
one left in the window. Thus TCP needs another RTO to continue.
The next FRTO, however, could again repeat the same events
making the progress of the TCP flow extremely slow.

In order for these events to occur at all, FRTO must occur
again in FRTOs step 3 while the key segments must be lost as
well, which is not too likely in practice. It seems to most
frequently with some small devices such as network printers
that *seem* to accept TCP segments only in-order. In cases
were key segments weren't lost, things get automatically
resolved because those wrongly marked segments don't need to be
retransmitted in order to continue.

I found a reproducer after digging up relevant reports (few
reports in total, none at netdev or lkml I know of), some
cases seemed to indicate middlebox issues which seems now
to be a false assumption some people had made. Bugzilla
#10063 _might_ be related. Damon L. Chesser <damon@damtek.com>
had a reproducable case and was kind enough to tcpdump it
for me. With the tcpdump log it was quite trivial to figure
out.

 module removal

As noticed by Ben Greear, macvlan crashes the kernel when unloading the
module. The reason is that it tries to clean up the macvlan_port pointer
on the macvlan device itself instead of the underlying device. A non-NULL
pointer is taken as indication that the macvlan_handle_frame_hook is
valid, when receiving the next packet on the underlying device it tries
to call the NULL hook and crashes.

Clean up the macvlan_port on the correct device to fix this.

Subject: [PATCH 221/869] netfilter: nf_conntrack_sip: restrict RTP expect
 flushing on error to last request

Some Inovaphone PBXs exhibit very stange behaviour: when dialing for
example "123", the device sends INVITE requests for "1", "12" and
"123" back to back.  The first requests will elicit error responses
from the receiver, causing the SIP helper to flush the RTP
expectations even though we might still see a positive response.

Note the sequence number of the last INVITE request that contained a
media description and only flush the expectations when receiving a
negative response for that sequence number.

Subject: [PATCH 223/869] netns: Fix arbitrary net_device-s corruptions on
 net_ns stop.

When a net namespace is destroyed, some devices (those, not killed
on ns stop explicitly) are moved back to init_net.

The problem, is that this net_ns change has one point of failure -
the __dev_alloc_name() may be called if a name collision occurs (and
this is easy to trigger). This allocator performs a likely-to-fail
GFP_ATOMIC allocation to find a suitable number. Other possible
conditions that may cause error (for device being ns local or not
registered) are always false in this case.

So, when this call fails, the device is unregistered. But this is
*not* the right thing to do, since after this the device may be
released (and kfree-ed) improperly. E. g. bridges require more
actions (sysfs update, timer disarming, etc.), some other devices
want to remove their private areas from lists, etc.

I. e. arbitrary use-after-free cases may occur.

The proposed fix is the following: since the only reason for the
dev_change_net_namespace to fail is the name generation, we may
give it a unique fall-back name w/o %d-s in it - the dev<ifindex>
one, since ifindexes are still unique.

So make this change, raise the failure-case printk loglevel to
EMERG and replace the unregister_netdevice call with BUG().

Found these two bugs while browsing through the code.  The first one is
a cut-n-paste bug, instead of disabling the clock when request_irq()
fails, it enabled it once more.  The second one fixes a debug printout,
AT91_SSC_IER is write only, AT91_SSC_IMR is readable (the printed string
actually says imr).

Frank Mandarino was busy so he asked me to send these to this list.

Subject: [PATCH 232/869] x86: geode: define geode_has_vsa2() even if
 CONFIG_MGEODE_LX is not set

We want drivers to be able to use geode_has_vsa2 without having to worry
about what model geode is being compiled for.  This patch ensures that
geode_has_vsa2 is always defined.

Subject: [PATCH 233/869] x86: cleanup PAT cpu validation

Move the scattered checks for PAT support to a single function. Its
moved to addon_cpuid_features.c as this file is shared between 32 and
64 bit.

Remove the manipulation of the PAT feature bit and just disable PAT in
the PAT layer, based on the PAT bit provided by the CPU and the
current CPU version/model white list.

Change the boot CPU check so it works on Voyager somewhere in the
future as well :) Also panic, when a secondary has PAT disabled but
the primary one has alrady switched to PAT. We have no way to undo
that.

The white list is kept for now to ensure that we can rely on known to
work CPU types and concentrate on the software induced problems
instead of fighthing CPU erratas and subtle wreckage caused by not yet
verified CPUs. Once the PAT code has stabilized enough, we can remove
the white list and open the can of worms.

|     Generic semaphore implementation
|
| After I manually reverted the patch against 2.6.26-rc1 while fixing
| lots of conflicts/errors, aim7 regression became less than 2%.

i reproduced the AIM7 workload and can confirm Yanmin's findings that
-.26-rc1 regresses over .25 - by over 67% here.

Looking at the workload i found and fixed what i believe to be the real
bug causing the AIM7 regression: it was inefficient wakeup / scheduling
/ locking behavior of the new generic semaphore code, causing suboptimal
performance.

The problem comes from the following code. The new semaphore code does
this on down():

        spin_lock_irqsave(&sem->lock, flags);
        if (likely(sem->count > 0))
                sem->count--;
        else
                __down(sem);
        spin_unlock_irqrestore(&sem->lock, flags);

and this on up():

        spin_lock_irqsave(&sem->lock, flags);
        if (likely(list_empty(&sem->wait_list)))
                sem->count++;
        else
                __up(sem);
        spin_unlock_irqrestore(&sem->lock, flags);

where __up() does:

        list_del(&waiter->list);
        waiter->up = 1;
        wake_up_process(waiter->task);

and where __down() does this in essence:

        list_add_tail(&waiter.list, &sem->wait_list);
        waiter.task = task;
        waiter.up = 0;
        for (;;) {
                [...]
                spin_unlock_irq(&sem->lock);
                timeout = schedule_timeout(timeout);
                spin_lock_irq(&sem->lock);
                if (waiter.up)
                        return 0;
        }

the fastpath looks good and obvious, but note the following property of
the contended path: if there's a task on the ->wait_list, the up() of
the current owner will "pass over" ownership to that waiting task, in a
wake-one manner, via the waiter->up flag and by removing the waiter from
the wait list.

That is all and fine in principle, but as implemented in
kernel/semaphore.c it also creates a nasty, hidden source of contention!

The contention comes from the following property of the new semaphore
code: the new owner owns the semaphore exclusively, even if it is not
running yet.

So if the old owner, even if just a few instructions later, does a
down() [lock_kernel()] again, it will be blocked and will have to wait
on the new owner to eventually be scheduled (possibly on another CPU)!
Or if another task gets to lock_kernel() sooner than the "new owner"
scheduled, it will be blocked unnecessarily and for a very long time
when there are 2000 tasks running.

I.e. the implementation of the new semaphores code does wake-one and
lock ownership in a very restrictive way - it does not allow
opportunistic re-locking of the lock at all and keeps the scheduler from
picking task order intelligently.

This kind of scheduling, with 2000 AIM7 processes running, creates awful
cross-scheduling between those 2000 tasks, causes reduced parallelism, a
throttled runqueue length and a lot of idle time. With increasing number
of CPUs it causes an exponentially worse behavior in AIM7, as the chance
for a newly woken new-owner task to actually run anytime soon is less
and less likely.

Note that it takes just a tiny bit of contention for the 'new-semaphore
catastrophy' to happen: the wakeup latencies get added to whatever small
contention there is, and quickly snowball out of control!

I believe Yanmin's findings and numbers support this analysis too.

The best fix for this problem is to use the same scheduling logic that
the kernel/mutex.c code uses: keep the wake-one behavior (that is OK and
wanted because we do not want to over-schedule), but also allow
opportunistic locking of the lock even if a wakee is already "in
flight".

The patch below implements this new logic. With this patch applied the
AIM7 regression is largely fixed on my quad testbox:

  # v2.6.25 vanilla:
  ..................
  Tasks   Jobs/Min        JTI     Real    CPU     Jobs/sec/task
  2000    56096.4         91      207.5   789.7   0.4675
  2000    55894.4         94      208.2   792.7   0.4658

  # v2.6.26-rc1-166-gc0a1811 vanilla:
  ...................................
  Tasks   Jobs/Min        JTI     Real    CPU     Jobs/sec/task
  2000    33230.6         83      350.3   784.5   0.2769
  2000    31778.1         86      366.3   783.6   0.2648

  # v2.6.26-rc1-166-gc0a1811 + semaphore-speedup:
  ...............................................
  Tasks   Jobs/Min        JTI     Real    CPU     Jobs/sec/task
  2000    55707.1         92      209.0   795.6   0.4642
  2000    55704.4         96      209.0   796.0   0.4642

i.e. a 67% speedup. We are now back to within 1% of the v2.6.25
performance levels and have zero idle time during the test, as expected.

Btw., interactivity also improved dramatically with the fix - for
example console-switching became almost instantaneous during this
workload (which after all is running 2000 tasks at once!), without the
patch it was stuck for a minute at times.

There's another nice side-effect of this speedup patch, the new generic
semaphore code got even smaller:

   text    data     bss     dec     hex filename
   1241       0       0    1241     4d9 semaphore.o.before
   1207       0       0    1207     4b7 semaphore.o.after

(because the waiter.up complication got removed.)

Longer-term we should look into using the mutex code for the generic
semaphore code as well - but i's not easy due to legacies and it's
outside of the scope of v2.6.26 and outside the scope of this patch as
well.

Subject: [PATCH 235/869] sched: fix weight calculations

The conversion between virtual and real time is as follows:

  dvt = rw/w * dt <=> dt = w/rw * dvt

Since we want the fair sleeper granularity to be in real time, we actually
need to do:

  dvt = - rw/w * l

This bug could be related to the regression reported by Yanmin Zhang:

| Comparing with kernel 2.6.25, sysbench+mysql(oltp, readonly) has lots
| of regressions with 2.6.26-rc1:
|
| 1) 8-core stoakley: 28%;
| 2) 16-core tigerton: 20%;
| 3) Itanium Montvale: 50%.

Subject: [PATCH 236/869] [SCSI] gdth: fix timer handling

The global timer handling is problematic in that if someone unbinds a
PCI gdth instance, the BUG_ON() in the timer will cause a panic.

Fix this by making the timer start and stop depending on whether there
are instances present.  This should also permit binding and unbinding
to work.

Subject: [PATCH 237/869] [SCSI] gdth: fix Error: Driver 'gdth' is already
 registered, aborting...

This message appears on modprobe/rmmod/modprobe of the driver.  It's
caused because if the driver has no instances, it returns an error
from gdth_init, which causes the module to fail to load.
Unfortunately, the module's pci driver is still registered at this
point.

Fix this by making gdth behave like a modern driver and insert even if
it doesn't find any instances (in case of hot plug or software driven
binding).

Subject: [PATCH 238/869] [SCSI] libiscsi regression in 2.6.25: fix nop timer
 handling

The following patch fixes a bug in the iscsi nop processing.
The target sends iscsi nops to ping the initiator and the
initiator has to send nops to reply and can send nops to
ping the target.

In 2.6.25 we moved the nop processing to the kernel to handle
problems when the userspace daemon is not up, but the target
is pinging us, and to handle when scsi commands timeout, but
the transport may be the cause (we can send a nop to check
the transport). When we added this code we added a bug where
if the transport timer wakes at the exact same time we are supposed to check
for a nop timeout we drop the session instead of checking the transport.

This patch checks if a iscsi ping is outstanding and if the ping has
timed out, to determine if we need to signal a connection problem.

Subject: [PATCH 239/869] [ARM] pxa: Fix RCSR handling

Related to d3930614e68bdf83a120d904c039a64e9f75dba1.

RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs.  Therefore,
we should not be unconditionally writing to RCSR from generic code.

Since we now clear the RCSR status from the SoC specific PXA PM code
and before reset in the arch_reset() function, the duplication in
the corgi, poodle, spitz and tosa code can be removed.

Subject: [PATCH 241/869] serial: access after NULL check in
 uart_flush_buffer()

I noticed that

  static void uart_flush_buffer(struct tty_struct *tty)
  {
  	struct uart_state *state = tty->driver_data;
  	struct uart_port *port = state->port;
  	unsigned long flags;

  	/*
  	 * This means you called this function _after_ the port was
  	 * closed.  No cookie for you.
  	 */
  	if (!state || !state->info) {
  		WARN_ON(1);
  		return;
  	}

is too late for checking state != NULL.

Subject: [PATCH 242/869] fix irq flags in mac80211 code

A file in the net/mac80211 directory uses "int" for flags.  This can cause
hard to find bugs on some architectures.  This patch converts the flags to use
"long" instead.

This bug was discovered by doing an allyesconfig make on the -rt kernel where
checks are done to ensure all flags are of size sizeof(long).

For e.g.  proper TTY canonical support, IUTF8 termios flag has to be set as
appropriate.  Linux used to not care about setting that flag for VT TTYs.

This patch fixes that by activating it according to the current mode of the
VT, and sets the default value according to the vt.default_utf8 parameter.

Subject: [PATCH 253/869] Fix cpuset sched_relax_domain_level control file

Due to a merge conflict, the sched_relax_domain_level control file was marked
as being handled by cpuset_read/write_u64, but the code to handle it was
actually in cpuset_common_file_read/write.

Since the value being written/read is in fact a signed integer, it should be
treated as such; this patch adds cpuset_read/write_s64 functions, and uses
them to handle the sched_relax_domain_level file.

With this patch, the sched_relax_domain_level can be read and written, and the
correct contents seen/updated.

alpha:

drivers/scsi/dpt_i2o.c:1997: error: implicit declaration of function 'adpt_alpha_info'
drivers/scsi/dpt_i2o.c: At top level:
drivers/scsi/dpt_i2o.c:2032: warning: conflicting types for 'adpt_alpha_info'
drivers/scsi/dpt_i2o.c:2032: error: static declaration of 'adpt_alpha_info' follows non-static declaration
drivers/scsi/dpt_i2o.c:1997: error: previous implicit declaration of 'adpt_alpha_info' was here

Due to a copy-n-paste error in drivers/scsi/dpti.h.

Fix that up and remove some of the many daft static-declarations-in-a-header
which this driver enjoys.

Subject: [PATCH 256/869] Fix drivers/media build for modular builds

Fix allmodconfig build bug introduced in latest -git by commit
7c91f0624a9 ("V4L/DVB(7767): Move tuners to common/tuners"):

  LD      kernel/built-in.o
  LD      drivers/built-in.o
  ld: drivers/media/built-in.o: No such file: No such file or directory

which happens if all media drivers are modular:

  http://redhat.com/~mingo/misc/config-Wed_Apr_30_09_24_48_CEST_2008.bad

In that case there's no obj-y rule connecting all the built-in.o files and
the link tree breaks.

The fix is to add a guaranteed obj-y rule for the core vmlinux to build.
(which results in an empty object file if all media drivers are modular)

Subject: [PATCH 260/869] [SCSI] libiscsi regression in 2.6.25: fix setting of
 recv timer

If the ping tmo is longer than the recv tmo then we could miss a window
where we were supposed to check the recv tmo. This happens because
the ping code will set the next timeout for the ping timeout, and if the
ping executes quickly there will be a long chunk of time before the
timer wakes up again.

This patch has the ping processing code kick off a recv
tmo check when getting a nop in response to our ping.

Changes the cputable so that various CPU families that have an exclusive
CONFIG_ option have a more sensible default entry to use if the specific
processor hasn't been identified.

This makes the kernel more generally useful when booted on an unknown
PVR for things like new 4xx variants.

mistake.  This causes memory corruption at boot.  This removes

Subject: [PATCH 271/869] [POWERPC] Document when printk is useable

When debugging early boot problems, it's common to sprinkle printk's
all over the place.  However, on 64-bit powerpc, this can lead to
memory corruption if done too early due to the PACA pointer and
lockdep core not being initialized.

This adds some comments to early_setup() that document when it is
safe to do so in order to save time for whoever has to debug that
stuff next.

Subject: [PATCH 276/869] [ARM] Orion: use mv643xx_eth driver mbus window
 handling

Make the Orion 5x platform code use the mbus window handling code
that's in the mv643xx_eth driver, instead of programming the GigE
block's mbus window registers by hand.

Subject: [PATCH 279/869] module: put modversions in vermagic

Don't allow a module built without versions altogether to be inserted
into a kernel which expects modversions.

modprobe --force will strip vermagic as well as modversions, so it
won't be effected, but this will make sure that a
non-CONFIG_MODVERSIONS module won't be accidentally inserted into a
CONFIG_MODVERSIONS kernel.

Subject: [PATCH 281/869] module: don't ignore vermagic string if module
 doesn't have modversions

Linus found a logic bug: we ignore the version number in a module's
vermagic string if we have CONFIG_MODVERSIONS set, but modversions
also lets through a module with no __versions section for modprobe
--force (with tainting, but still).

We should only ignore the start of the vermagic string if the module
actually *has* crcs to check.  Rather than (say) having an
entertaining hissy fit and creating a config option to work around the
buggy code.

From: Paul Walmsley <paul@pwsan.com>
Date: Wed, 7 May 2008 16:55:13 -0700
Subject: [PATCH 285/869] ARM: OMAP: Add calls to omap2_set_globals_*()

Add the omap2_set_globals_{242x,243x,343x}() functions. These
functions are called early upon boot in the map_io() functions in the
board-specific init files.

This patch was accidentally left out of the earlier series.

This fixes omap2 booting as noted by Kyungmin Park <kmpark@infradead.org>.

Function enable_lnk does incorrect channel link on non-omap1 builds if chain

Fix this by making sure that next_linked_ch field is initialized to -1 just
in omap_request_dma.

 drivers earlier.

A lot of stuff in spitz/akita/etc. depends on corgi_ssp to be initialised
early. However corgi_ssp initialisation fails, because at that time pxa*-ssp
devices don't have drivers. Move ssp earlier in the makefile so they are
registered before corgi-ssp.

Also move sleep/suspend and cpu-freq to more logical places

Subject: [PATCH 301/869] x86: restrict keyboard io ports reservation to make
 ipmi driver work

On some of our (single board computer) boards (x86) we are using an
IPMI controller that uses I/O ports 0x62 and 0x66 for a KCS (keyboard
controller style) IPMI system interface.

Trying to load the openipmi driver fails, because the ports
(0x62/0x66) are reserved for keyboard. keyboard reserves the full
range 0x60-0x6F while it doesn't need to.

Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad
controller instead of 0x60-0x6F to allow the openipmi driver to work.

[ tglx: added 64bit fixup ]

709f744 causes my computer to freeze during the start up of X and my
login manger (GDM). It gets to the point where it has shown the default
X mouse cursor logo (a big X / cross) and does not respond to anything
from that point on.

This worked fine before 709f744, and it works fine with 709f744
reverted on top of Linus' current tree (f74d505). The revert had
conflicts, as far as I can tell due to white space changes. The diff I
ended up with is below.

Subject: [PATCH 303/869] x86: sysfs cpu?/topology is empty in 2.6.25 (32-bit
 Intel system)

System topology on intel based system needs to be exported
for non-numa case as well.

All parts of asm-i386/topology.h has come under
#ifdef CONFIG_NUMA after the merge to asm-x86/topology.h

/sys/devices/system/cpu/cpu?/topology/* is populated based on
ENABLE_TOPO_DEFINES

The sysfs cpu topology is not being populated on my dual socket
dual core xeon 5160 processor based (x86 32 bit) system.

CONFIG_NUMA is not set in my case yet the topology is relevant
and useful.

irqbalance daemon application depends on topology to build the
cpus and package list and it fails on Fedora9 beta since the
sysfs topology was not being populated in the 2.6.25 kernel.

I am not sure if it was intentional to not define ENABLE_TOPO_DEFINES
for non-numa systems.

This fix has been tested on the above mentioned dual core, dual socket
system.

It actually makes much more sense there, and we do tend to need it for

other cases that have open-coded the same logic to use the same helper

Subject: [PATCH 307/869] Revert "semaphore: fix"

This reverts commit bf726eab3711cf192405d21688a4b21e07b6188a, as it has
been reported to cause a regression with processes stuck in __down(),
apparently because some missing wakeup.

Quoth Sven Wegener:
 "I'm currently investigating a regression that has showed up with my
  last git pull yesterday.  Bisecting the commits showed bf726e
  "semaphore: fix" to be the culprit, reverting it fixed the issue.

  Symptoms: During heavy filesystem usage (e.g.  a kernel compile) I get
  several compiler processes in uninterruptible sleep, blocking all i/o
  on the filesystem.  System is an Intel Core 2 Quad running a 64bit
  kernel and userspace.  Filesystem is xfs on top of lvm.  See below for
  the output of sysrq-w."

See

	http://lkml.org/lkml/2008/5/10/45

for full report.

In the meantime, we can just fix the BKL performance regression by
reverting back to the good old BKL spinlock implementation instead,
since any sleeping lock will generally perform badly, especially if it
tries to be fair.

Subject: [PATCH 308/869] BKL: revert back to the old spinlock implementation

The generic semaphore rewrite had a huge performance regression on AIM7
(and potentially other BKL-heavy benchmarks) because the generic
semaphores had been rewritten to be simple to understand and fair.  The
latter, in particular, turns a semaphore-based BKL implementation into a
mess of scheduling.

The attempt to fix the performance regression failed miserably (see the
previous commit 00b41ec2611dc98f87f30753ee00a53db648d662 'Revert
"semaphore: fix"'), and so for now the simple and sane approach is to
instead just go back to the old spinlock-based BKL implementation that
never had any issues like this.

This patch also has the advantage of being reported to fix the
regression completely according to Yanmin Zhang, unlike the semaphore
hack which still left a couple percentage point regression.

As a spinlock, the BKL obviously has the potential to be a latency
issue, but it's not really any different from any other spinlock in that
respect.  We do want to get rid of the BKL asap, but that has been the
plan for several years.

These days, the biggest users are in the tty layer (open/release in
particular) and Alan holds out some hope:

  "tty release is probably a few months away from getting cured - I'm
   afraid it will almost certainly be the very last user of the BKL in
   tty to get fixed as it depends on everything else being sanely locked."

so while we're not there yet, we do have a plan of action.

Subject: [PATCH 309/869] kbuild: escape meta characters in regular expression
 in make TAGS

Alexey Dobriyan <adobriyan@gmail.com> introduced a code adds
menuconfig SOMETHING in Kconfig to tags output when you did "make tags".

See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=80ff26241623875636674a31c0540a78c0fb5433

"make tags" may work fine with his code. However make TAGS doesn't work well
because etags command requires backslashes to escape meta characters like
`(', `)' and `|'.

Here is a patch.

Disable modpost warnings for linkonce sections

My build gives lots of warnings like

WARNING: sound/core/snd.o (.gnu.linkonce.wi.mpspec_def.h.30779716): unexpected section name.
The (.[number]+) following section name are ld generated and not expected.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.

But for .linkonce. duplicated sections are actually ok and expected.
So just disable the warning for this case.

With commit 3f1b0e1f287547903f11fa1e6de7d2765597766e ".gitignore update"
Linus's current git tree starts to ignore any "*.rej" files.
So "git status" no longer shows these files, but the ones who works with
quilt patchsets, this not makes life easier as expected.
Because sometimes a work flow (at least for me) requires
"quilt push -f" followed by "git status" to see unresolved merge
conflicts, work on these conflicts to correct them and finalize
the patch with "quilt refresh".

And if there are some "*.rej" files exists in tree, for whatever
reason, this means something goes really wrong there and i think
this situation not deserves to be ignored.

Subject: [PATCH 313/869] sparc: Fix ptrace() detach.

Forever we had a PTRACE_SUNOS_DETACH which was unconditionally
recognized, regardless of the personality of the process.

Unfortunately, this value is what ended up in the GLIBC sys/ptrace.h
header file on sparc as PTRACE_DETACH and PT_DETACH.

So continue to recognize this old value.  Luckily, it doesn't conflict
with anything we actually care about.

Subject: [PATCH 314/869] sparc: Fix debugger syscall restart interactions.

So, forever, we've had this ptrace_signal_deliver implementation
which tries to handle all of the nasties that can occur when the
debugger looks at a process about to take a signal.  It's meant
to address all of these issues inside of the kernel so that the
debugger need not be mindful of such things.

Problem is, this doesn't work.

The idea was that we should do the syscall restart business first, so
that the debugger captures that state.  Otherwise, if the debugger for
example saves the child's state, makes the child execute something
else, then restores the saved state, we won't handle the syscall
restart properly because we lose the "we're in a syscall" state.

The code here worked for most cases, but if the debugger actually
passes the signal through to the child unaltered, it's possible that
we would do a syscall restart when we shouldn't have.

In particular this breaks the case of debugging a process under a gdb
which is being debugged by yet another gdb.  gdb uses sigsuspend
to wait for SIGCHLD of the inferior, but if gdb itself is being
debugged by a top-level gdb we get a ptrace_stop().  The top-level gdb
does a PTRACE_CONT with SIGCHLD to let the inferior gdb see the
signal.  But ptrace_signal_deliver() assumed the debugger would cancel
out the signal and therefore did a syscall restart, because the return
error was ERESTARTNOHAND.

Fix this by simply making ptrace_signal_deliver() a nop, and providing
a way for the debugger to control system call restarting properly:

1) Report a "in syscall" software bit in regs->{tstate,psr}.
   It is set early on in trap entry to a system call and is fully
   visible to the debugger via ptrace() and regsets.

2) Test this bit right before doing a syscall restart.  We have
   to do a final recheck right after get_signal_to_deliver() in
   case the debugger cleared the bit during ptrace_stop().

3) Clear the bit in trap return so we don't accidently try to set
   that bit in the real register.

As a result we also get a ptrace_{is,clear}_syscall() for sparc32 just
like sparc64 has.

M68K has this same exact bug, and is now the only other user of the
ptrace_signal_deliver hook.  It needs to be fixed in the same exact
way as sparc.

The driver is apparently returning 0 on failure and 1 on success.
That's a bit unfortunate.  Fix it by altering to -ENODEV and 0.

The problem is that the driver calls aha152x_release() under a
list_for_each_entry().  Unfortunately, aha152x_release() deletes from
the list in question.  Fix this by using list_for_each_entry_safe().

Subject: [PATCH 319/869] [CIFS]  add local struct inode pointer to
 cifs_setattr

Clean up cifs_setattr a bit by adding a local inode pointer, and
changing all of the direntry->d_inode references to it. This also adds a
bit of micro-optimization. d_inode shouldn't change over the life of
this function, so we only need to dereference it once.

Subject: [PATCH 320/869] [CIFS] when not using unix extensions, check for and
 set ATTR_READONLY on create and mkdir

When creating a directory on a CIFS share without POSIX extensions,
and the given mode has no write bits set, set the ATTR_READONLY bit.

When creating a file, set ATTR_READONLY if the create mode has no write
bits set and we're not using unix extensions.

There are some comments about this being problematic due to the VFS
splitting creates into 2 parts. I'm not sure what that's actually
talking about, but I'm assuming that it has something to do with how
mknod is implemented. In the simple case where we have no unix
extensions and we're just creating a regular file, there's no reason
we can't set ATTR_READONLY.

Subject: [PATCH 321/869] [CIFS] don't allow demultiplex thread to exit until
 kthread_stop is called

cifs_demultiplex_thread can exit under several conditions:

1) if it's signaled
2) if there's a problem with session setup
3) if kthread_stop is called on it

The first two are problems. If kthread_stop is called on the thread,
there is no guarantee that it will still be up. We need to have the
thread stay up until kthread_stop is called on it.

One option would be to not even try to tear things down until after
kthread_stop is called. However, in the case where there is a problem
setting up the session, there's no real reason to try continuing the
loop.

This patch allows the thread to clean up and prepare for exit under all
three conditions, but it has the thread go to sleep until kthread_stop
is called. This allows us to simplify the shutdown code somewhat since
we can be reasonably sure that the thread won't exit after being
signaled but before kthread_stop is called.

It also removes the places where the thread itself set the tsk variable
since it appeared that it could have a potential race where the thread
might never be shut down.

Alter the mpc i2c driver to use the NO_IRQ symbol instead of the constant
zero when checking for valid interrupts. NO_IRQ=-1 on ppc and NO_IRQ=0 on
powerpc so the checks against zero are not correct.

Subject: [PATCH 323/869] i2c-piix4: Increase the intitial delay for the
 ServerWorks CSB5

Per the PIIX4 errata, there maybe a delay between setting the
start bit in the Smbus Host Controller Register and the transaction
actually starting. If the driver doesn't delay long enough, it
may appear that the transaction is complete when actually it
hasn't started, this may lead to bus collisions.

While 1 ms appears to be enough for most chips, the ServerWorks CSB5
wants 2 ms.

We had a report that running sensors-detect on a Sapphire AM2RD790
motherbord killed the CPU. While the exact cause is still unknown,
I'd rather play it safe and prevent any access to the SMBus on that
machine by not letting the i2c-piix4 driver attach to the SMBus host
device on that machine. Also blacklist a similar board made by DFI.

Subject: [PATCH 325/869] i2c: Improve smbus-protocol documentation

Improve the smbus-protocol documentation file somewhat:

 - Use the names of the SMBus protocol operations (from the 2.0
   specification), not made-up-for-Linux names.

 - Add the name of the call used to execute each operation ... and
   point out that there are mismatches, where functions execute
   different protocol operations than their names specify.

The most confusing examples are that "Read Byte" isn't executed by
i2c_smbus_read_byte(), and that "Write Byte" isn't executed by
i2c_smbus_write_byte().  When coding, that's not as bad as it may
seem; but that case would seem to be worth fixing.

+I2C_FUNC_I2C without any help from the adapter driver. The idea is
+to let the client drivers check for the support of SMBus functions

+Here, the lm75 driver checks if the adapter can do both SMBus byte data
+and SMBus word data transactions. If not, then the driver won't work on
+this adapter and there's no point in going on. If the check above is
+successful, then the driver knows that it can call the following
+functions: i2c_smbus_read_byte_data(), i2c_smbus_write_byte_data(),
+i2c_smbus_read_word_data() and i2c_smbus_write_word_data(). As a rule of
+thumb, the functionality constants you test for with
+i2c_check_functionality() should match exactly the i2c_smbus_* functions
+which you driver is calling.
+
+Note that the check above doesn't tell whether the functionalities are
+implemented in hardware by the underlying adapter or emulated in
+software by i2c-core. Client drivers don't have to care about this, as

Subject: [PATCH 329/869] i2c: Match dummy devices by type

As the old driver_name/type matching scheme is going away soon, change
the dummy device mechanism to use the new matching scheme.

This has the downside that dummy i2c clients can no longer choose
their name, they'll all appear as "dummy" in sysfs and in log
messages. I don't think it is a problem in practice though, as there
is little reason to use these i2c clients to log messages.

Subject: [PATCH 332/869] Add new 'cond_resched_bkl()' helper function

It acts exactly like a regular 'cond_resched()', but will not get
optimized away when CONFIG_PREEMPT is set.

Normal kernel code is already preemptable in the presense of
CONFIG_PREEMPT, so cond_resched() is optimized away (see commit
02b67cc3ba36bdba351d6c3a00593f4ec550d9d3 "sched: do not do
cond_resched() when CONFIG_PREEMPT").

But when wanting to conditionally reschedule while holding a lock, you
need to use "cond_sched_lock(lock)", and the new function is the BKL
equivalent of that.

Also make fs/locks.c use it.

Subject: [PATCH 335/869] [Blackfin] arch: Blackfin checksum annotations

FSVOtest in this case, since I don't have the hardware...
However, all changes seen by gcc are actually
 - explicit cast to unsigned short in return expression of functions
    returning unsigned short
 - csum_fold() return type changed from unsigned int to __sum16
   (unsigned short), same as for all other architecture and as net/* expects;
   expression actually returned is ((~(sum << 16)) >> 16) with sum being
   unsigned 32bit, so it's (a) going to fit into the range of unsigned short
   and (b) had been unsigned all along, so no sign expansion mess happened.

Subject: [PATCH 336/869] sparc64: Work around memory probing bug in
 openfirmware.

Read all of the OF memory and translation tables, then read
the physical available memory list twice.

When making these requests, OF can allocate more memory to
do it's job, which can remove pages from the available
memory list.

So fetch in all of the tables at once, and fetch the available
list last to make sure we read a stable value.

If socket is create by PF_INET type, it can not used IPv6 address to
send/recv DATA, So we can not used IPv6 address even if peer tell us it
support IPv6 address.
This patch fix to only enabled peer IPv6 address support on PF_INET6 socket.

This patch add address type check before process paramaters of ASCONF

Subject: [PATCH 344/869] syncppp: Fix crashes.

The syncppp layer wants a mid-level netdev private pointer.

It was using netdev->priv but that only worked by accident,
and thus this scheme was broken when the device private
allocation strategy changed.

Add a proper mid-layer private pointer for uses like this,
update syncppp and all users, and remove the HDLC_PPP broken
tag from drivers/net/wan/Kconfig

Subject: [PATCH 345/869] [POWERPC] ppc: More compile fixes

This fixes a few more miscellaneous compile problems with ARCH=ppc.

1. Don't compile devres.c on ARCH=ppc, it doesn't have ioremap_flags.
2. Include <asm/irq.h> in setup.c for the __DO_IRQ_CANON definition.
3. Include <linux/proc_fs.h> in residual.c for the
   definition of create_proc_read_entry.
4. Fix xchg_ptr to be a static inline to eliminate a compiler warning.

Subject: [PATCH 349/869] [MIPS] Alchemy: SMBus resource fix

The Alchemy platform code registers the SMBus device using the virtual
address of its registers instead of the physical one -- fix this, taking
into account that actually the whole megabyte is decoded by any of the
programmable serial controllers (one of which is SMBus), and that all the
Alchemy peripherals are directly mappable into KSEG1 kernel space and
therefore ioremap() call would just boil down to CKSEG1ADDR() invocation.

Subject: [PATCH 354/869] [MIPS] IRIX: Handle do_brk() error return correctly.

do_brk's return value was stored in an unsigned long variable before being
tested for less than zero making the test always fail.  Also do_brk's
called irix_map_prda_page wasn't forwarding do_brk() success.

Bug checking the return value of do_brk() and initial fix for it found
by Roel Kluin <12o3l@tiscali.nl>.

This is to clarify that GCC_IMM_ASM does not take an argument as the

As suggested by Maciej W. Rozycki (macro@linux-mips.org).

Subject: [PATCH 359/869] [MIPS] Alchemy common headers style cleanup

Fix several errors and warnings given by checkpatch.pl:

- space after opening and before closing parentheses;

- opening brace following 'struct' not on the same line;

- leading spaces instead of tabs;

- use of C99 // comments;

- macros with complex values not enclosed in parentheses;

- missing space between the type and asterisk in a variable declaration;

- space between asterisk and function name;

- including <asm/io.h> instead of <linux/io.h> and <asm/irq.h> instead of
  <linux/irq.h>;

- use of '__inline__' instead of 'inline';

- space between function name and opening parenthesis;

- line over 80 characters.

In addition to these changes, also do the following:

- remove needless parentheses;

- insert spaces between operator and its operands;

- replace spaces after the macro name with tabs in the #define directives and
  after the type in the structure field declarations;

- remove excess tabs after the macro name in the #define directives and in the
  'extern' variable declarations;

- remove excess spaces between # and define for the SSI_*_MASK macros to align
  with other such macros;

- put '||' operator on the same line with its first operand;

- properly indent multi-line function prototypes;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first line and/or adding space/asterisk on their left side;

- make two-line comments that only have one line of text one-line;

- convert the large multi-line comment in au1xxx_ide.h into several one-liners,
  replace spaces with tabs there;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- insert missing and remove excess new lines;

- update MontaVista copyright;

- remove Pete Popov's and Steve Longerbeam's old email addresses...

Subject: [PATCH 360/869] [MIPS] Alchemy common code style cleanup

Fix many errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- missing space between the type and asterisk in a variable declaration;

- space between the asterisk and function/variable name;

- leading spaces instead of tabs;

- space after opening and before closing parentheses;

- initialization of a 'static' variable to 0;

- missing spaces around assignement/comparison operator;

- brace not on the same line with condition (or 'else') in the 'if'/'switch'
  statement;

- missing space between 'if'/'for'/'while' and opening parenthesis;

- use of assignement in 'if' statement's condition;

- printk() without KERN_* facility level;

- EXPORT_SYMBOL() not following its function immediately;

- unnecessary braces for single-statement block;

- adding new 'typedef' (where including <linux/types.h> will do);

- use of 'extern' in the .c file (where it can be avoided by including header);

- line over 80 characters.

In addition to these changes, also do the following:

- insert missing space after opening brace and/or before closing brace in the
  structure initializers;

- insert spaces between operator and its operands;

- put the function's result type and name/parameters on the same line;

- properly indent multi-line expressions;

- remove commented out code;

- remove useless initializers and code;

- remove needless parentheses;

- fix broken/excess indentation;

- add missing spaces between operator and its operands;

- insert missing and remove excess new lines;

- group 'else' and 'if' together where possible;

- make au1xxx_platform_init() 'static';

- regroup variable declarations in pm_do_freq() for prettier look;

- replace numeric literals with the matching macros;

- fix printk() format specifiers mismatching the argument types;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first line and/or adding space on their left side;

- make two-line comments that only have one line of text one-line;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- fix/remove obsolete references in the comments;

- reformat some comments;

- add comment about the CPU:counter clock ratio to calc_clock();

- update MontaVista copyright;

- remove Pete Popov's and Steve Longerbeam's old email addresses...

Subject: [PATCH 361/869] [MIPS] Alchemy PCI code style cleanup

Fix 15 errors and 4 warnings given by checkpatch.pl:

- space between the asterisk and variable name;

- space after opening and before closing parentheses;

- leading spaces instead of tabs;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

- line over 80 characters.

In addition to these changes, also do the following:

- combine the nested 'if' statements into one when possible;

- remove needless parentheses;

- add missing and remove excess spaces between operator and its operands;

- fix printk() format specifiers mismatching the argument types;

- put the function's result type and name/parameters on the same line;

- insert missing and remove excess new lines;

- properly indent multi-line expressions;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first line;

- fix typos, capitalize acronyms, etc. in the comments;

- update MontaVista copyright;

- remove Pete Popov's old email address...

Subject: [PATCH 362/869] [MIPS] DBAu1xx0 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- macros with complex values not enclosed in parentheses;

- leading spaces instead of tabs;

- printk() without KERN_* facility level;

- using simple_strtol() where strict_strtol() could be used;

- line over 80 characters.

In addition to these changes, also do the following:

- initialize variable instead of assigning value later where it makes sense;

- insert spaces between operator and its operands, also remove excess spaces
  there;

- remove unneeded numeric literal type casts;

- remove needless parentheses;

- remove space after the type cast's closing parenthesis;

- insert missing space before closing brace in the array initializers;

- replace spaces after the macro name with tabs in the #define directives;

- remove excess tabs after the macro name in the #define directives;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first/last line;

- update MontaVista copyright;

- remove Pete Popov's old email address...

From 7916c3548e53bffb0545a1d0dc7fde86d79add92 Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
Date: Wed, 30 Apr 2008 23:25:55 +0400
Subject: [PATCH 363/869] [MIPS] Pb1000 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- brace not on the same line with condition in the 'switch' statement;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

- using simple_strtol() where strict_strtol() could be used.

In addition to these changes, also do the following:

- properly indent the 'switch' statement;

- remove needless parentheses;

- insert spaces between operator and its operands;

- replace numeric literals/expressions with the matching macros;

- remove useless #if dirctive from board_setup();

- remove unneeded numeric literal type casts;

- remove space after the type cast's closing parenthesis;

- replace spaces after the macro name with tabs in the #define directives, and
  sometimes insert spaces there;

- remove excess new lines;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first/last line;

- combine some comments;

- update MontaVista copyright;

- remove Pete Popov's old email address...

From be1c3c1ed13f31ae8f9d5d043d96d2e56b5ee1d5 Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
Date: Wed, 30 Apr 2008 23:26:28 +0400
Subject: [PATCH 364/869] [MIPS] Pb1100 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- space between asterisk and variable name;

- use of C99 // comments;

- using simple_strtol() where strict_strtol() could be used.

In addition to these changes, also do the following:

- properly indent the code;

- remove space after the type cast's closing parenthesis;

- replace numeric literals/expressions with the matching macros;

- replace spaces after the macro name with tabs in the #define directives,
  and sometimes insert spaces there;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- make the multi-line comment style consistent with the kernel style
  elsewhere by adding empty first line;

- update MontaVista copyright;

- remove Pete Popov's old email address...

From 2091a17ff7f32432976d1eacbb79a06819d95301 Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
Date: Wed, 30 Apr 2008 23:27:20 +0400
Subject: [PATCH 365/869] [MIPS] Pb1500 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

- using simple_strtol() where strict_strtol() could be used.

In addition to these changes, also do the following:

- replace numeric literals/expressions with the matching macros;

- insert spaces between operator and its operands;

- properly indent the code and the array initializers;

- remove useless #if dirctive from board_setup();

- remove needless parentheses;

- remove unneeded type casts;

- remove excess new lines;

- make hexadecimal literals all lower case;

- remove space after the type cast's closing parenthesis;

- insert missing space before closing brace in the array initializers;

- replace spaces after the macro name with tabs in the #define directives,
  also sometimes insert space there for better looks;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- update MontaVista copyright;

- remove Pete Popov's old email address...

Subject: [PATCH 366/869] [MIPS] Pb1550 code style cleanup

Fix a few errors and warnings given by checkpatch.pl:

- macros with complex values not enclosed in parentheses;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

- using simple_strtol() where strict_strtol() could be used.

In addition to these changes, also do the following:

- replace numeric literals with the matching macros;

- properly indent the code and the array initializers;

- insert spaces between operator and its operands, also remove excess spaces
  there;

- remove space after the type cast's closing parenthesis;

- insert missing space before closing brace in the array initializers;

- replace spaces after the macro name with tabs in the #define directives, also
  sometimes insert space there for better looks;

- remove excess tabs after the macro name in the #define directives;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first line;

- update MontaVista copyright;

- remove Pete Popov's old email address...

Subject: [PATCH 367/869] [MIPS] Pb1200/DBAu1200 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- initialization of a 'static' variable to 0;

- space after opening and before closing parentheses;

- missing space between 'for' and opening parenthesis;

- macros with complex values not enclosed in parentheses;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

- using simple_strtol() where strict_strtol() could be used;

- line over 80 characters.

In addition to these changes, also do the following:

- mention DBAu1200 board in the Makefile;

- replace the group of #include/#ifdef directives by a single
  #include <au1xxx.h> since this header contains the needed stuff;

- properly indent the blocks;

- insert spaces between operator and its operands, remove excess spaces
  there;

- remove needless parentheses and add some for clarity;

- replace numeric literals/expressions with the matching macros;

- remove space after the type cast's closing parenthesis;

- reduce pb1200_setup_cascade() to the single 'return' statement;

- reduce the number of printed empty lines in the so-called CPLD
  workaround;

- remove #undef AU1X00_EXTERNAL_INT since that macro is not defined
  anywhere;

- replace spaces after the macro name with tabs in the #define directives;

- remove excess tabs after the macro name in the #define directives;

- fix typo in the BCSR_RESETS_PWMR1mUX macro's name;

- group all Pb1200 PCMCIA definitions together;

- put the function's result type and name/parameters on the same line;

- insert missing and remove excess new lines;

- make the multi-line comment style consistent with the kernel style
  elsewhere by adding empty first line and/or adding space/asterisk on
  their left side;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- combine some comments;

- update MontaVista copyright;

- remove Pete Popov's old email address...

From 1ff1a78cbb6fb6ceafac1b2cbdd72c939a7c9bae Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
Date: Wed, 30 Apr 2008 23:30:12 +0400
Subject: [PATCH 368/869] [MIPS] MTX-1 code style cleanup

Fix many errors and warnings given by checkpatch.pl:

- space after opening and before closing parentheses;

- use of C99 // comments;

- leading spaces instead of tabs;

- brace not on the same line with 'else' in the 'if' statement;
  statement;

- printk() without KERN_* facility level;

- using simple_strtol() where strict_strtol() could be used.

- including <asm/gpio.h> instead of <linux/gpio.h>.

In addition to these changes, also do the following:

- insert spaces between operator and its operands;

- replace tab between the function type and name with space in
  mtx1_pci_idsel() declaration;

- remove space after the type cast's closing parenthesis;

- insert missing space before closing brace in the array/structure
  initializers;

Subject: [PATCH 369/869] [MIPS] XXS1500 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- using simple_strtol() where strict_strtol() could be used.

In addition to these changes, also do the following:

- remove needless parentheses;

- remove unneeded numeric literal type cast;

- insert spaces between operator and its operands;

- remove excess new lines;

- remove space after the type cast's closing parenthesis;

- insert missing space before closing brace in the structure initializer;

- fix typos, capitalize acronyms, etc. in the comments;

- update MontaVista copyright;

- remove Pete Popov's old email address...

these cpus.

56a6b1eb7bfb5ace0b5cb9c149f502fbd101b8ab was a bit too conservative and
left __ilog2 around which is only used as an internal function for other

Subject: [PATCH 378/869] Fix up 'need_resched()' definition

We should not go through the task pointer to get at the thread info,
since it's usually cheaper to just access the thread info directly.

So don't make the code look up 'current', when we can just use the
thread info accessor functions directly.  This generally avoids one
level of indirection and tends to work better together with code that
also looks at other thread flags (eg preempt_count).

That patch is buggy. We had an implicit assumption that
dev = NULL for ISA devices that require 24bit DMA.

The recent work on x86 dma_alloc_coherent() breaks the ISA DMA buffer
allocation, which is represented by "dev = NULL" and requires 24bit
DMA implicitly.

The phys_cpu_present_map is an expected symbol in the SMP harness.
Unfortunately, x86 recently moved this and a few others to
kernel/setup.c where it doesn't quite work because voyager has to
define its own.  Use CONFIG_X86_LOCAL_APIC to isolate these
definitions and fix up another area in setup.c where CONFIG_X86_SMP
should be used instead of CONFIG_SMP.

Subject: [PATCH 382/869] Make 'cond_resched()' nullification depend on
 PREEMPT_BKL

Because it's not correct with a non-preemptable BKL and just causes
PREEMPT kernels to have longer latencies than non-PREEMPT ones (which is
obviously not the point of it at all).

Of course, that config option actually got removed as an option earlier,
so for now this basically disables it entirely, but if BKL preemption is
ever resurrected it will be a meaningful optimization.  And in the
meantime, it at least documents the intent of the code, while not doing
the wrong thing.

Subject: [PATCH 383/869] pppol2tp: Remove null pointer dereference.

If session is NULL, it is not possible to access its name field.  So I
have split apart the printing of the error message to drop the
printing of the name field in this case.

The macro PRINTK actually only evaluates its arguments starting with
the third one if the bitwise conjunction of the first two is non-zero.
Normally, this conjunction would only be non-zero if debugging mode
were turned on, but when session is NULL, the first argument in both
the old and new code is -1, and thus the bitwise conjunction is true.
Perhaps a different strategy is desired, such as using tunnel->debug,
which session->debug is initialized to, but tunnel can also be NULL,
so this does not completely solve the problem.


This problem was found using the following semantic match
(http://www.emn.fr/x-info/coccinelle/)

Subject: [PATCH 384/869] sparc: Fix mremap address range validation.

Just like mmap, we need to validate address ranges regardless
of MAP_FIXED.

sparc{,64}_mmap_check()'s flag argument is unused, remove.

Based upon a report and preliminary patch by
Jan Lieskovsky <jlieskov@redhat.com>

Subject: [PATCH 385/869] lmb: Fix inconsistent alignment of size argument.

When allocating, if we will align up the size when making
the reservation, we should also align the size for the
check that the space is actually available.

The simplest thing is to just aling the size up from
the beginning, then we can use plain 'size' throughout.

Subject: [PATCH 386/869] lmb: Make lmb debugging more useful.

Having to muck with the build and set DEBUG just to
get lmb_dump_all() to print things isn't very useful.

So use pr_info() and use an early boot param
"lmb=debug" so we can simply ask users to reboot
with this option when we need some debugging from
them.

Subject: [PATCH 388/869] fix irq flags in mac80211 code

A file in the net/mac80211 directory uses "int" for flags.  This can cause
hard to find bugs on some architectures.  This patch converts the flags to use
"long" instead.

This bug was discovered by doing an allyesconfig make on the -rt kernel where
checks are done to ensure all flags are of size sizeof(long).

Subject: [PATCH 390/869] mac80211: fix debugfs default key oops

Under certain circumstances (in AP mode) the debugfs function
that is supposed to add the default key symlink can encounter
a NULL default_key pointer. This patch makes it handle that
situtation gracefully.

Subject: [PATCH 392/869] rt2x00: Don't use pskb_expand_head()

rt2x00pci allocates DMA for descriptor and data,
rt61pci doesn't use this for the beacon, but it can
use the descriptor part as temporary buffer instead
of using pskb_expand_head().
Using this temporary buffer is obviously much better
then reallocating the skb buffer...

At the same time we can set the data length for the
beacon queue at 0, to make sure no DMA is allocated for
data (but just for the descriptor).

Subject: [PATCH 393/869] rt2x00: Fix broken recover-on-error path

During initialization the initialize() callback function
in rt2x00pci and rt2x00usb will cleanup the mess they made.

rt2x00lib shouldn't call uninitialize because the callback function already
cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the
rt2x00lib_uninitialize() to halt directly anyway. All that is required
to be cleaned up by rt2x00lib is the queue, and that can be done by
calling rt2x00queue_uninitialize() directly.

Subject: [PATCH 394/869] rt2x00: Clean up error handling of PCI queue DMA
 allocation.

When, for some reason, the rt2x00pci module fails to allocate DMA memory for
the queues, it tries to undo the complete initialization of the PCI device,
including freeing of the irq. This results in the following error in dmesg, as
the irq hadn't been requested yet:

[  78.123456] Trying to free already-free IRQ 17

Fix this by implementing proper error handling code, instead of just using the
full uninitialization function.

Subject: [PATCH 400/869] Fix not checked kmalloc() result.

The new_node kmallocation is not checked for success, so add
this check.

BTW, it also happens under the read_lock.

Calling synchronize_rcu() under write-lock-ed pathtbl_resize_lock may
result in this warning (and other side effects).

It looks safe just dropping this lock before calling synchronize_rcu.

Subject: [PATCH 404/869] mac80211: fix association with some APs

Some APs refuse association if the supported rates contained in the
association request do not match its own supported rates. This patch
introduces a new function which builds the intersection between the AP's
supported rates and the client's supported rates to work around such
problems. The same approach is already used in ipw2200 for example.

Subject: [PATCH 407/869] net: Set LL_MAX_HEADER properly for wireless.

Wireless networking, particularly with MESH enabled, has
quite strong requirements for link-layer header space.

Based upon some numbers and descriptions from Johannes Berg
we use 96 (same as AX25) for plain wireless, and with
mesh enabled we use 128.

In the process, simplify the cpp conditional logic here by
ordering the cases by those needing the most space down
to those needing the least case.

This patch adds needed_headroom/needed_tailroom members to struct

all of them can be converted though, and I'm sure I missed some (I
mostly grepped for LL_RESERVED_SPACE)

Subject: [PATCH 418/869] myri10ge: increase and fix handoff timeout

Increase the handoff timeout to 512ms so as to give the aeluros based
NICs sufficient time to handoff without relying on the msleep() being
sloppy, and accidentally sleeping way longer than the 20ms we specified
in 20 separate 1ms sleeps.

Fix typo in the handoff sleep delay, which made it additive, not
exponential.

Subject: [PATCH 426/869] myri10ge: fix the number of interrupt slots

Fix a long-standing bug/misunderstanding between the
driver and the firmware.  The size of the interrupt
queue must be set to the number of rx slots (big + small),
and it should never have been a tunable.
Setting it too small results in chaos.

From b9b39b625cf57cd0ea998717598b68963cbec3cb Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Wed, 7 May 2008 12:51:12 +0100
Subject: [PATCH 433/869] [netdrvr] sfc: Add TSO support

The SFC4000 controller does not have hardware support for TSO, and the
core GSO code incurs a high cost in allocating and freeing skbs.  This
TSO implementation uses lightweight packet header structures and is
substantially faster.

Subject: [PATCH 434/869] [netdrvr] sfc: Add phy_flash_cfg module parameter and
 implementation

The 10Xpress PHY supports flash upgrades through MDIO, but needs to be
put in upgrade mode at power-up.  This adds a module parameter and other
logic to support that.

Subject: [PATCH 448/869] tcp FRTO: Fix fallback to conventional recovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It seems that commit 009a2e3e4ec ("[TCP] FRTO: Improve
interoperability with other undo_marker users") run into
another land-mine which caused fallback to conventional
recovery to break:

1. Cumulative ACK arrives after FRTO retransmission
2. tcp_try_to_open sees zero retrans_out, clears retrans_stamp
   which should be kept like in CA_Loss state it would be
3. undo_marker change allowed tcp_packet_delayed to return
   true because of the cleared retrans_stamp once FRTO is
   terminated causing LossUndo to occur, which means all loss
   markings FRTO made are reverted.

This means that the conventional recovery basically recovered
one loss per RTT, which is not that efficient. It was quite
unobvious that the undo_marker change broken something like
this, I had a quite long session to track it down because of
the non-intuitiviness of the bug (luckily I had a trivial
reproducer at hand and I was also able to learn to use kprobes
in the process as well :-)).

This together with the NewReno+FRTO fix and FRTO in-order
workaround this fixes Damon's problems, this and the first
mentioned are enough to fix Bugzilla #10063.

Subject: [PATCH 449/869] tcp FRTO: work-around inorder receivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If receiver consumes segments successfully only in-order, FRTO
fallback to conventional recovery produces RTO loop because
FRTO's forward transmissions will always get dropped and need to
be resent, yet by default they're not marked as lost (which are
the only segments we will retransmit in CA_Loss).

Price to pay about this is occassionally unnecessarily
retransmitting the forward transmission(s). SACK blocks help
a bit to avoid this, so it's mainly a concern for NewReno case
though SACK is not fully immune either.

This change has a side-effect of fixing SACKFRTO problem where
it didn't have snd_nxt of the RTO time available anymore when
fallback become necessary (this problem would have only occured
when RTO would occur for two or more segments and ECE arrives
in step 3; no need to figure out how to fix that unless the
TODO item of selective behavior is considered in future).

Subject: [PATCH 450/869] [ALSA] emux midi synthesizer doesn't honor
 SOFT_PEDAL-release event

When the hardware wavetable synthesizer of an Creative SB Audigy or SB
Live! card (with emu10k chip) receives the MIDI SOFT_PEADAL-press event
(?? 67 127) the appropriate voice is attenuted. Unfortunately when the
pedal is released (event ?? 67 0) the voice does not get it's original
volume again.

Boolean MIDI controls should interpret 0..63 as false and 64..127 as true.
Thanks to Clemens Ladisch for review and correction.

Subject: [PATCH 455/869] [POWERPC] 86xx: mpc8610_hpcd: use ULI526X driver for
 on-board ethernet

As of current mainline tree, TULIP driver is unusable on MPC8610HPCD
boards. There is a patch[1] floating around (and also included in the
BSP), which tries to heal the situation, though the ethernet is still
unusable. Practically it takes ages to mount NFS filesystem:

VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 180k init
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying

So, instead of trying to add uli526x functionality into TULIP driver
(which is already bloated enough), I fixed existing ULI526X driver
and now it works perfectly well here.

The 8568 MDS needs some configuration changes to the PHY in order to
work properly.  These are done in the firmware, normally, but Linux
shouldn't need to rely on the firmware running such things (someone
could disable the PHY support in the firmware to save space, for instance).

DIU platform code should not just write to the PIXIS' BRDCFG0 register,
it should set and clear its own bits only, otherwise it will break
firmware setup (in fact it breaks second uart).

Also get rid of magic numbers in the related code.

Subject: [PATCH 461/869] [POWERPC] 85xx: SBC8548 - Add flash support and HW
 Rev reporting

The following adds local bus, flash and MTD partition nodes for
sbc8548. As well, a compatible field for the soc node, so that
of_platform_bus_probe() will pick it up.

Something that is provided through this newly added epld node
is the Hardware Revision which is now being utilized.

Subject: [PATCH 462/869] uml: redo host capability detection and disabling

Redo how host capabilities are recorded at startup and disabled on the
command line.

There are now explicit variables saying what's been disabled by the
command line rather than the implicitness of the have_* variable being
zero.  The capability variables now start at zero and are set to one
as their capabilities are found to be present on the host.

Subject: [PATCH 464/869] uml: hppfs fixes

hppfs tidying and fixes noticed during hch's get_inode work -
      style fixes
      a copy_to_user got its return value checked
      hppfs_write no longer fiddles file->f_pos because it gets and
returns pos in its arguments
      hppfs_delete_inode dputs the underlyng procfs dentry stored in
its private data and mntputs the vfsmnt stashed in s_fs_info
      hppfs_put_super no longer needs to mntput the s_fs_info, so it
no longer needs to exist
      hppfs_readlink and hppfs_follow_link were doing a bunch of stuff
with a struct file which they didn't use
      there is now a ->permission which calls generic_permission
      get_inode was always returning 0 for some reason - it now
returns an inode if nothing bad happened

Subject: [PATCH 468/869] uml: fix build when SLOB is enabled

Reintroduce uml_kmalloc for the benefit of UML libc code.  The
previous tactic of declaring __kmalloc so it could be called directly
from the libc side of the house turned out to be getting too intimate
with slab, and it doesn't work with slob.

So, the uml_kmalloc wrapper is back.  It calls kmalloc or whatever
that translates into, and libc code calls it.

kfree is left alone since that still works, leaving a somewhat
inconsistent API.

Subject: [PATCH 470/869] uml: fix bad NTP interaction with clock

UML's supposed nanosecond clock interacts badly with NTP when NTP
decides that the clock has drifted ahead and needs to be slowed down.
Slowing down the clock is done by decrementing the cycle-to-nanosecond
multiplier, which is 1.  Decrementing that gives you 0 and time is
stopped.

This is fixed by switching to a microsecond clock, with a multiplier
of 1000.

Subject: [PATCH 474/869] uml: use PAGE_SIZE in linker scripts

This patch includes page.h header into linker scripts that allow us to
use PAGE_SIZE macro instead of numeric constant.

To be able to include page.h into linker scripts page.h is needed for
some modification - i.e.  we need to use __ASSEMBLY__ and _AC macro

The top of physical memory should be below the initial process stack, not the
top of the address space, at least for as long as the stack isn't known to the
kernel VM system and appropriately reserved.

Subject: [PATCH 476/869] uml: random driver fixes

The random driver would essentially hang if the host's /dev/random returned
-EAGAIN.  There was a test of need_resched followed by a schedule inside the
loop, but that didn't help and it's the wrong way to work anyway.

The right way is to ask for an interrupt when there is input available from
the host and handle it then rather than polling.

Now, when the host's /dev/random returns -EAGAIN, the driver asks for a wakeup
when there's randomness available again and sleeps.  The interrupt routine
just wakes up whatever processes are sleeping on host_read_wait.

There is an atomic_t, host_sleep_count, which counts the number of processes
waiting for randomness.  When this reaches zero, the interrupt is disabled.

An added complication is that async I/O notification was only recently added
to /dev/random (by me), so essentially all hosts will lack it.  So, we use the
sigio workaround here, which is to have a separate thread poll on the
descriptor and send an interrupt when there is input on it.  This mechanism is
activated when a process gets -EAGAIN (activating this multiple times is
harmless, if a bit wasteful) and deactivated by the last process still
waiting.

The module name was changed from "random" to "hw_random" in order for udev to
recognize it.

The sigio workaround needed some changes.  sigio_broken was added for cases
when we know that async notification doesn't work.  This is now called from
maybe_sigio_broken, which deals with pts devices.

Subject: [PATCH 478/869] uml: track and make up lost ticks

Alarm delivery could be noticably late in the !CONFIG_NOHZ case because lost
ticks weren't being taken into account.  This is now treated more carefully,
with the time between ticks being calculated and the appropriate number of
ticks delivered to the timekeeping system.

There is a typo in pxa2xx_spi.c, comment says "Enable the SSP clock", code
says: clk_disable ...  so after resume, the SSP is dead.

Subject: [PATCH 480/869] drivers/misc/sgi-xp: clean up return values

Make XP return values more generic to XP and not so tied to XPC by changing
enum xpc_retval to xp_retval, along with changing return value prefixes from
xpc to xp.  Also, cleanup a comment block that referenced some of these return
values as well as the handling of BTE related return values.

- * to functions registered by xpc_connect(). A "NA" in that column indicates
- * that this reason code can be passed to functions registered by
- * xpc_send_notify() (i.e. they don't have data arguments).
+ * A reason code of xpConnected indicates that a connection has been
+ * established to the specified partition on the specified channel. The data
+ * argument indicates the max number of entries allowed in the message queue.
  *
- * Also, the first three reason codes in the following table indicate
- * success, whereas the others indicate failure. When a failure reason code
- * is received, one can assume that the channel is not connected.
+ * A reason code of xpMsgReceived indicates that a XPC message arrived from
+ * the specified partition on the specified channel. The data argument
+ * specifies the address of the message's payload. The user must call
+ * xpc_received() when finished with the payload.

From 8dc4e37362a5dc910d704d52ac6542bfd49ddc2f Mon Sep 17 00:00:00 2001
From: Miklos Szeredi <mszeredi@suse.cz>
Date: Mon, 12 May 2008 14:02:04 -0700
Subject: [PATCH 482/869] ecryptfs: clean up (un)lock_parent

dget(dentry->d_parent) --> dget_parent(dentry)

unlock_parent() is racy and unnecessary.  Replace single caller with
unlock_dir().

There are several other suspect uses of ->d_parent in ecryptfs...

Subject: [PATCH 483/869] m68knommu: ColdFire add support for kernel preemption
 (missing chunk)

As the subject says this patch adds the support for kernel preemption on
m68knommu Coldfire.  I thing the same changes could be applied to 68360 &
68328 but since I don't have the HW, I don't touch it.  Kconfig enables the
preemption item only on coldfire.

This is a missing chunk from Sebastian's original patch that I lost from the
first submission.

Subject: [PATCH 486/869] quota: don't call sync_fs() from vfs_quota_off() when
 there's no quota turn off

Sometimes, vfs_quota_off() is called on a partially set up super block (for
example when fill_super() fails for some reason).  In such cases we cannot
call ->sync_fs() because it can Oops because of not properly filled in super
block.  So in case we find there's not quota to turn off, we just skip
everything and return which fixes the above problem.

Subject: [PATCH 490/869] md: fix raid5 'repair' operations

commit bd2ab67030e9116f1e4aae1289220255412b37fd "md: close a livelock window
in handle_parity_checks5" introduced a bug in handling 'repair' operations.
After a repair operation completes we clear the state bits tracking this
operation.  However, they are cleared too early and this results in the code
deciding to re-run the parity check operation.  Since we have done the repair
in memory the second check does not find a mismatch and thus does not do a
writeback.

Test results:
$ echo repair > /sys/block/md0/md/sync_action
$ cat /sys/block/md0/md/mismatch_cnt
51072
$ echo repair > /sys/block/md0/md/sync_action
$ cat /sys/block/md0/md/mismatch_cnt
0

(also fix incorrect indentation)

There is currently no way to query the bounding set of another task.  As there
appears to be no security reason not to, and as Michael Kerrisk points out the
following valid reasons to do so exist:

* consistency (I can see all of the other per-thread/process sets in
  /proc/.../status)

* debugging -- I could imagine that it would make the job of debugging an
  application that uses capabilities a little simpler.

this patch adds the bounding set to /proc/self/status right after the
effective set.

Subject: [PATCH 494/869] drivers/video/pnx4008: eliminate double free

The function framebuffer_release just calls kfree, so calling kfree
subsequently on the same argument represents a double free.  The comments with
the definition of framebuffer_release in drivers/video/fbsysfs.c suggest that
a more elaborate definition of this function is planned, such that the
splitting up of framebuffer_release and kfree as done in the second instance
might someday make sense, but it does not make sense now.

Fix an oops with a corrupted hfs+ image.

See http://bugzilla.kernel.org/show_bug.cgi?id=10548 for details.

Problem is that we call hfs_btree_open() from hfsplus_fill_super() to set
HFSPLUS_SB(sb).[ext_tree|cat_tree] Both trees are still NULL at this moment.
If hfs_btree_open() fails for any reason it calls iput() on the page, which
gets to hfsplus_releasepage() which tries to access HFSPLUS_SB(sb).* which is
still NULL and oopses while dereferencing it.

Subject: [PATCH 502/869] rtc: rtc_time_to_tm: use unsigned arithmetic

The input argument to rtc_time_to_tm() is unsigned as well as are members of
the output structure.  However signed arithmetic is used within for
calculations leading to incorrect results for input values outside the signed
positive range.  If this happens the time of day returned is out of range.

Found the problem when fiddling with the RTC and the driver where year was set
to an unexpectedly large value like 2070, e.g.:

rtc0: setting system clock to 2070-01-01 1193046:71582832:26 UTC (3155760954)

while it should be:

rtc0: setting system clock to 2070-01-01 00:15:54 UTC (3155760954)

Changing types to unsigned fixes the problem.

Subject: [PATCH 505/869] cpumask: remove bitmap_scnprintf_len and
 cpumask_scnprintf_len

They aren't used.  They were briefly used as part of some other patches to
provide an alternative format for displaying some /proc and /sys cpumasks.
They probably should have been removed when those other patches were dropped,
in favor of a different solution.

Subject: [PATCH 506/869] spi_mpc83xx: much improved driver

The current driver may cause glitches on SPI CLK line since one must disable
the SPI controller before changing any HW settings.  Fix this by implementing
a local spi_transfer function that won't change speed and/or word size while
CS is active.

While doing that heavy lifting a few other issues were addressed too:
 - Make word size 16 and 32 work too.
 - Honor bits_per_word and speed_hz in spi transaction.
 - Optimize the common path.

This also stops using the "bitbang" framework (except for a few constants).

Subject: [PATCH 507/869] memcg: fix possible panic when CONFIG_MM_OWNER=y

When mm destruction happens, we should pass mm_update_next_owner() the old mm.
 But unfortunately new mm is passed in exec_mmap().

Thus, kernel panic is possible when a multi-threaded process uses exec().

Also, the owner member comment description is wrong.  mm->owner does not
necessarily point to the thread group leader.

Subject: [PATCH 509/869] fuse: add flag to turn on big writes

Prior to 2.6.26 fuse only supported single page write requests.  In theory all
fuse filesystem should be able support bigger than 4k writes, as there's
nothing in the API to prevent it.  Unfortunately there's a known case in
NTFS-3G where big writes cause filesystem corruption.  There could also be
other filesystems, where the lack of testing with big write requests would
result in bugs.

To prevent such problems on a kernel upgrade, disable big writes by default,
but let filesystems set a flag to turn it on.

bdevname() fills the buffer that it is given as a parameter, so calling

Subject: [PATCH 514/869] vt/fbcon: update scrl_erase_char after 256/512-glyph
 font switch

Addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b ("vt: fix
background color on line feed").

vc->vc_scrl_erase_char was not updated when fbcon switches between
256- and 512-glyph fonts.

Subject: [PATCH 515/869] vt/fbcon: fix background color on line feed

Another addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b
("vt: fix background color on line feed").

fbcon still was not doing the right thing (read: continued to do old
behavior).  fbcon_clear() seems to clear the new line (e.g.  where your new
prompt appears after doing echo -en "\e[42mfoo\n"), while scr_memsetw clears
the previous one only (where "foo" appears).  So just temporarily set the
video_erase_char to the scrl_erase_char so that fbcon_clear does the right
thing.

Subject: [PATCH 517/869] PCI ACPI: fix uninitialized variable in
 __pci_osc_support_set

Fix uninitialized variable in __pci_osc_support_set().

If the ACPI namespace doesn't have any device object corresponding to
the specified hid, 'retval' in __pci_osc_support_set() is not changed
by the acpi_query_osc() callback. Since 'retval' is not initizlized in
the current implementation, the contents of 'retval' is undefined in
this case. This causes a mis-handling of ctrlset_buf[OSC_SUPPORT_TYPE]
and will cause an unexpected result in the subsequent
pci_osc_control_set() call as a result.

Subject: [PATCH 518/869] x86/PCI: fix broken ISA DMA

Rene Herman reported:

That patch is buggy. We had an implicit assumption that
dev = NULL for ISA devices that require 24bit DMA.

The recent work on x86 dma_alloc_coherent() breaks the ISA DMA buffer
allocation, which is represented by "dev = NULL" and requires 24bit
DMA implicitly.

Subject: [PATCH 520/869] ACPI/PCI: handle multiple _OSC

The pci_osc_control_set() function can be called for the ACPI object
that doesn't have _OSC method. In this case, acpi_get_osc_data() would
allocate a useless memory region. To avoid this, we need to check the
existence of _OSC before calling acpi_get_osc_data(). Here is a patch
to fix this problem in pci_osc_control_set.

The following patch changes the intel-iommu.c code to use the TSC
instead of jiffies for detecting bad DMAR functionality.  Some systems
with bad bios's have been seen to hang in early boot spinning in the
IOMMU_WAIT_IO macro.  This patch will replace the infinite loop with a call to
panic.

This applies the NVidia MSI enabled flag for HT capable devices quirk
to ALi bridges as well.

As described in more detail in http://bugzilla.kernel.org/show_bug.cgi?id=10667
this is required for my board which is using an nForce 3 250Gb chipset with an
ALi M1695 northbridge.

It fixes a regression introduced in 2.6.24 that made the internal NIC of the
board unusable (MSI initialisation of the NIC but disabled MSI on the
northbridge devices.

Subject: [PATCH 523/869] x86/PCI: X86_PAT & mprotect

Some versions of X used the mprotect workaround to change caching type from UC
to WB, so that it can then use mtrr to program WC for that region [1].  Change
the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS.
With this change, X will not need to use mprotect workaround to get WC type
since the MTRR mapping type will be honored.

The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So,
this X workaround will stop working as well.

The acpi_query_osc() function can be called for the ACPI object that
doesn't have _OSC method. In this case, acpi_get_osc_data() would
allocate a useless memory region. To avoid this, we need to check the
existence of _OSC before calling acpi_get_osc_data() in acpi_query_osc().

Subject: [PATCH 525/869] [SCSI] qla1280: Fix queue depth problem

The qla1280 driver was ANDing the output value of mailbox register
0 with (1 << target-number) to determine whether to enable queueing
on the target in question.

But mailbox register 0 has the status code for the mailbox command
(in this case, Set Target Parameters).  Potential values are:
/*
 * ISP mailbox command complete status codes
 */

So clearly that is in error.  I can't think what the author of that
line was looking for in a mailbox register, so I just eliminated the
AND.  flag is used later in the function, and I think that the later
usage was also wrong, though it was used to set values that aren't
used.  Oh well, an overhaul of this driver is not what I want to do
now -- just a bugfix.

After the fix, I found that my disks were getting a queue depth of
255, which is far too many.  Most SCSI disks are limited to 32 or
64.  In any case, there's no point, queueing up a bunch of commands
to the adapter that will just result in queue full or starve other
targets from being issued commands due to running out of internal
memory.  So I dropped default queue depth to 32 (from which 1 is
subtracted elsewhere, giving net of 31).

I tested with a Seagate ST336753LC, and results look good, so
I'm satisfied with this patch.

Subject: [PATCH 526/869] x86: fix app crashes after SMP resume

After resume on a 2cpu laptop, kernel builds collapse with a sed hang,
sh or make segfault (often on 20295564), real-time signal to cc1 etc.

Several hurdles to jump, but a manually-assisted bisect led to -rc1's
d2bcbad5f3ad38a1c09861bca7e252dde7bb8259 x86: do not zap_low_mappings
in __smp_prepare_cpus.  Though the low mappings were removed at bootup,
they were left behind (with Global flags helping to keep them in TLB)
after resume or cpu online, causing the crashes seen.

Reinstate zap_low_mappings (with local __flush_tlb_all) for each cpu_up
on x86_32.  This used to be serialized by smp_commenced_mask: that's now
gone, but a low_mappings flag will do.  No need for native_smp_cpus_done
to repeat the zap: let mem_init zap BSP's low mappings just like on UP.

(In passing, fix error code from native_cpu_up: do_boot_cpu returns a
variety of diagnostic values, Dprintk what it says but convert to -EIO.
And save_pg_dir separately before zap_low_mappings: doesn't matter now,
but zapping twice in succession wiped out resume's swsusp_pg_dir.)

That worked well on the duo and one quad, but wouldn't boot 3rd or 4th
cpu on P4 Xeon, oopsing just after unlock_ipi_call_lock.  The TLB flush
IPI now being sent reveals a long-standing bug: the booting cpu has its
APIC readied in smp_callin at the top of start_secondary, but isn't put
into the cpu_online_map until just before that unlock_ipi_call_lock.

So native_smp_call_function_mask to online cpus would send_IPI_allbutself,
including the cpu just coming up, though it has been excluded from the
count to wait for: by the time it handles the IPI, the call data on
native_smp_call_function_mask's stack may well have been overwritten.

So fall back to send_IPI_mask while cpu_online_map does not match
cpu_callout_map: perhaps there's a better APICological fix to be
made at the start_secondary end, but I wouldn't know that.

    ERROR: "csum_partial" [fs/reiserfs/reiserfs.ko] undefined!
    make[1]: *** [__modpost] Error 1
    make: *** [modules] Error 2

This is due to a known weakness of symbol exports: if a symbol's
only in-core user is an EXPORT_SYMBOL from a lib-y section, the
symbol is not linked in.

The solution is to move the export to x8664_ksyms_64.c - but the real
solution would be to fix kbuild.

Subject: [PATCH 530/869] x86: user_regset_view table fix for ia32 on 64-bit

The user_regset_view table for the 32-bit regsets on the 64-bit build had
the wrong sizes for the FP regsets.  This bug had no user-visible effect
(just on kernel modules using the user_regset interfaces and the like).
But the fix is trivial and risk-free.

Subject: [PATCH 531/869] RDMA/nes: Fix up nes_lro_max_aggr module parameter

Fix some bugs with the max_aggr module parameter added with LRO support:

 - The module parameter value ignored and not actually used to set
   lro_mgr.max_aggr.
 - MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
   end up describing the actual module parameter.
 - The nes_lro_max_aggr variable was declared as unsigned, but the
   module_param line said "int" instead of "uint" for the type.
 - The default value for the parameter was stuck in the permissions
   field of module_param, which led to nonsensical permissions for the
   file under /sys/module/iw_nes/param.
 - The parameter was used in only one file but defined in another, which
   led to the variable being global for no good reason.  Move everything
   related to the parameter to the file nes_hw.c where it is actually
   used.

Subject: [PATCH 532/869] IB/ipath: Fix RC and UC error handling

When errors are detected in RC, the QP should transition to the
IB_QPS_ERR state, not the IB_QPS_SQE state. Also, when the error is on
the responder side, the receive work completion error was incorrect
(remote vs. local).

From e509be898d8937634437caa474b57ac12795e5bc Mon Sep 17 00:00:00 2001

Subject: [PATCH 533/869] IB/ipath: Fix many locking issues when switching to
 error state

The send DMA hardware queue voided a number of prior assumptions about
when a send is complete which led to completions being generated out of
order.  There were also a number of locking issues when switching the QP
to the error or reset states, and we implement the IB_QPS_SQD state.

If an out of sequence RDMA read response middle or last packet is
received, we should only resend the RDMA read request on the first
out of sequence packet and drop subsequent out of sequence packets
otherwise, we get "too many retries".

Subject: [PATCH 535/869] IB/ipath: Make ipath_portdata work with struct pid *
 not pid_t

The official reason is "with the presence of pid namespaces in the
kernel using pid_t-s inside one is no longer safe."

But the reason I fix this right now is the following:

About a month ago (when 2.6.25 was not yet released) there still was a
one last caller of a to-be-deprecated-soon function find_pid() - the
kill_proc() function, which in turn was only used by nfs callback
code.

During the last merge window, this last caller was finally eliminated
by some NFS patch(es) and I was about to finally kill this kill_proc()
and find_pid(), but found, that I was late and the kill_proc is now
called from the ipath driver since commit 58411d1c ("IB/ipath: Head of
Line blocking vs forward progress of user apps").

So here's a patch that fixes this code to use struct pid * and (!)
the kill_pid routine.

Subject: [PATCH 536/869] IB/ipath: Change ipath_devdata.ipath_sdma_status to
 be unsigned long

Andrew Morton <akpm@linux-foundation.org> pointed out that bitops
should take an unsigned long * arg.  However, the ipath driver was
doing bitops on struct ipath_devdata.ipath_sdma_status, which is u64.
Change this member to unsigned long to avoid tons of warnings when x86
fixes the bitops to take unsigned long * instead of void *.

Also, change the IPATH_SDMA_RUNNING and IPATH_SDMA_SHUTDOWN bit
numbers to 30 and 31 (instead of 62 and 63) so that we're not setting
another booby trap for someone who tries to make ipath work on a
32-bit architecture.

Subject: [PATCH 538/869] ext4: correct mount option parsing to detect when
 quota options can be changed

We should not allow user to change quota mount options when quota is
just suspended.  It would make mount options and internal quota state
inconsistent.  Also we should not allow user to change quota format when
quota is turned on.  On the other hand we can just silently ignore when
some option is set to the value it already has (mount does this on
remount).

In journal=data mode, it is not enough to do write_inode_now as done in
vfs_quota_on() to write all data to their final location (which is
needed for quota_read to work correctly).  Calling journal_flush() does
its job.

Subject: [PATCH 542/869] ext4: mballoc fix mb_normalize_request algorithm for
 1KB block size filesystems

In case of inode preallocation, the number of blocks to allocate depends
on the file size and it is calculated in ext4_mb_normalize_request().
Each group in the filesystem is then checked to find one that can be
used for allocation; this is done in ext4_mb_good_group().

When a file bigger than 4MB is created, the requested number of blocks
to preallocate, calculated by ext4_mb_normalize_request is 4096.
However for a filesystem with 1KB block size, the maximum size of the
block buddies used by the multiblock allocator is 2048, so none of
groups in the filesystem satisfies the search criteria in
ext4_mb_good_group(). Scanning all the filesystem groups impacts
performance.

This was demonstrated by using a freshly created, 70GB, 1k block
filesystem, with caches dropped write before the test via
/proc/sys/vm/drop_caches, and with the filesystem mounted with
nodelalloc and nodealloc,nomballoc.  The time to write an 8 megabyte
file using "dd if=/dev/zero of=/mnt/test/fo bs=8k count=1k conv=fsync"
took 35.5091 seconds (236kB/s) with nodellaloc, and 0.233754 seconds
(35.9 MB/s) with the nodelloc,nomballoc options.  With a 1TB partition,
it took several minutes to write 8MB!

This patch modifies the algorithm in ext4_mb_normalize_group_request to
calculate the number of blocks to allocate by taking into account the
maximum size of free blocks chunks handled by the multiblock allocator.

It has also been tested for filesystems with 2KB and 4KB block sizes to
ensure that those cases don't regress.

Subject: [PATCH 546/869] V4L/DVB (7804): tea5767: Fix error logic

As pointed by Andrew Morton, the error testing were wrong. After reviewing
tea5767, it were returning a positive value for errors.

So, the double errors were cancelling each other.

This patch fix it properly. It also considers any positive value as ok, on
tuner-core.

Subject: [PATCH 552/869] V4L/DVB (7813): Fix compilation, when V4L1_COMPAT is
 disabled

This driver uses some sysfs helper functions that are available only for legacy
drivers. It also requires linux/mm.h.

This patch fixes compiliation when not in compat mode.

Thanks to Ingo Molnar for identifying this issue.

Subject: [PATCH 556/869] V4L/DVB (7829): cx23885: remove remaining references
 to dvb-pll

The cx23885 driver used to use dvb-pll for LG-TDVS-H064F support on the
FusionHDTV5 Express.  This has since been converted to use tuner-simple
instead, once digital tuning support was added to tuner-simple.

Since cx23885 no longer uses dvb-pll, remove the #include "dvb-pll.h",
and the DVB_PLL Kconfig selection.

Subject: [PATCH 557/869] V4L/DVB (7830): dvb_ca_en50221: Fix High CPU load in
 'top' due to budget_av slot polling

This change addresses kernel bug #10459: In kernel 2.6.25 the
budget_av driver polls for an CI slot in 100ms intervals (because no
interrupt solution for budget_av cards is feasible due to HW reasons).
If no CI/CAM is connected to the DVB card, polling times out only after 250ms.
This periodic polling leads to high CPU load.

The change increases the polling interval for empty slots from 100ms to 5s.
Intervals for remaining slot states (invalid, in progress, ready) are unchanged,
as they are either temporary conditions or no timeout should occur.

x86.git testing found the following build failure in v2.6.26-rc1:

  MODPOST 424 modules

with this config:

  http://redhat.com/~mingo/misc/config-Sat_May__3_22_28_58_CEST_2008.bad

this patch does what other video drivers do to utilize the
VIDEO_TVEEPROM functionality (and this resolves the build problem) - but
i have not checked it on real hardware and i have not checked whether
the fix is complete.

selections, so some items might still be missing - just not triggered
with this specific config.

Subject: [PATCH 561/869] V4L/DVB (7836): cinergyT2 build fix

x86.git testing found the following build bug in v2.6.26-rc1:

  drivers/built-in.o: In function `cinergyt2_probe':
  cinergyT2.c:(.text+0xb6117): undefined reference to `input_allocate_device'
  cinergyT2.c:(.text+0xb6230): undefined reference to `input_register_device'
  cinergyT2.c:(.text+0xb623d): undefined reference to `input_free_device'

with the following config:

  http://redhat.com/~mingo/misc/config-Sun_May__4_22_06_54_CEST_2008.bad

The reason for the bug is that the cinergyT2 driver depends on
CONFIG_INPUT functionality, but if INPUT is modular it's still possible
to build CONFIG_DVB_CINERGYT2=y - which leads to missing symbols.

The solution is to make DVB_CINERGYT2 dependent on INPUT.

[ This solves the build problem - i have not tested the driver on this card. ]

Subject: [PATCH 570/869] V4L/DVB (7846): Re-creates VIDEO_TUNER

VIDEO_TUNER is responsible for compilation of tuners.ko module. This were the
previous behaviour before the creation of MEDIA_TUNER.

Before this patch, tuner.ko were created even for drivers that don't need a
tuner (like webcam drivers).

Subject: [PATCH 572/869] V4L/DVB (7848): Fix dependencies for tuner-xc2028 and
 em28xx-dvb

em28xx-dvb doesn't need FW_LOADER. Instead, tuner-xc2028 needs to select
FW_LOADER.

Also, this can happen only if HOTPLUG is selected, since FW_LOADER
is dependent on HOTPLUG.

Subject: [PATCH 573/869] V4L/DVB (7849): cx88: fix Kconfig depencencies for
 FW_LOADER

cx88 doesn't need support for FW_LOADER. Instead, this is required only for
cx88-blackbird.

Also, cx88-blackbird depends on HOTPLUG, due to FW_LOADER dependency.

Subject: [PATCH 574/869] V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvb

Since:
1) FW_LOADER is defined as:

config FW_LOADER
        tristate "Userspace firmware loading support"
        depends on HOTPLUG

2) several V4L/DVB driver just selects it;

3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.

So, All drivers that select FW_LOADER should also depend on HOTPLUG.

An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:

drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->
USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB

Subject: [PATCH 577/869] V4L/DVB (7854): cx18/ivtv: improve and fix
 out-of-memory handling

- don't show kernel backtrace when the allocation of the buffers fails: the
  normal ivtv/cx18 messages are clear enough and the backtrace scares users.
- fix cleanup after the buffer allocation fails (caused kernel panic).

Subject: [PATCH 578/869] V4L/DVB (7856): cx18/: possible cleanups

This patch contains the following possible cleanups:
- cx18-i2c.c should #include "cx18-i2c.h" for getting the prototypes of
  it's global functions
- make the following needlessly global functions static:
  - cx18-fileops.c:cx18_claim_stream()
  - cx18-fileops.c:cx18_release_stream()
  - cx18-queue.c:cx18_queue_move()
- remove the following unused functions:
  - cx18-driver.c:cx18_waitq()
  - cx18-queue.c:cx18_buf_copy_from_user()

Subject: [PATCH 580/869] V4L/DVB (7858): video: build fix for
 drivers/media/video/mt9v022.c

x86.git testing found the following build bug on latest -git:

  CC [M]  drivers/media/video/mt9v022.o

  make[2]: *** [drivers/media/video] Error 2
  make[1]: *** [drivers/media] Error 2
  make[1]: *** Waiting for unfinished jobs....
  make: *** [drivers] Error 2

with this config:

   http://redhat.com/~mingo/misc/config-Sat_May__3_16_08_39_CEST_2008.bad

the bug was that the driver uses GPIO functionality but only includes
the GPIO interface definitions for the CONFIG_MT9M001_PCA9536_SWITCH
case, which was not set in this config.

The quick fix seems to be to include linux/gpio.h unconditionally. (this
seems like a small cleanup as well as it removes and #ifdef is more
robust than an inclusion of asm/gpio.h) Not tested too much yet, so
please have another look in any case.

 mt312_, Add zl10313 to kconfig description

This patch does some small cleanup to mt312.
It changes kconfig description to also list the ZL10313.

It does change some strange symbol names to be consistent with
module name mt312 and naming of all other functions in there.
* vp310_mt312_ops -> mt312_ops
* vp310_mt312_attach -> mt312_attach

Adds a MODULE_AUTHOR for me

+/*
+    History of this driver (Steven Toth):
+      I was given a public release of a linux driver that included
+      support for the MaxLinear MXL5005S silicon tuner. Analysis of
+      the tuner driver showed clearly three things.
+
+      1. The tuner driver didn't support the LinuxTV tuner API
+	 so the code Realtek added had to be removed.
+
+      2. A significant amount of the driver is reference driver code
+	 from MaxLinear, I felt it was important to identify and
+	 preserve this.
+
+      3. New code has to be added to interface correctly with the
+	 LinuxTV API, as a regular kernel module.
+
+      Other than the reference driver enum's, I've clearly marked
+      sections of the code and retained the copyright of the
+      respective owners.

-    History of this driver (Steven Toth):
-      I was given a public release of a linux driver that included
-      support for the MaxLinear MXL5005S silicon tuner. Analysis of
-      the tuner driver showed clearly three things.
-
-      1. The tuner driver didn't support the LinuxTV tuner API
-	 so the code Realtek added had to be removed.
-
-      2. A significant amount of the driver is reference driver code
-	 from MaxLinear, I felt it was important to identify and
-	 preserve this.
-
-      3. New code has to be added to interface correctly with the
-	 LinuxTV API, as a regular kernel module.
-
-      Other than the reference driver enum's, I've clearly marked
-      sections of the code and retained the copyright of the
-      respective owners.

+/*
+    History of this driver (Steven Toth):
+      I was given a public release of a linux driver that included
+      support for the MaxLinear MXL5005S silicon tuner. Analysis of
+      the tuner driver showed clearly three things.
 
+      1. The tuner driver didn't support the LinuxTV tuner API
+	 so the code Realtek added had to be removed.
+
+      2. A significant amount of the driver is reference driver code
+	 from MaxLinear, I felt it was important to identify and
+	 preserve this.
+
+      3. New code has to be added to interface correctly with the
+	 LinuxTV API, as a regular kernel module.
+
+      Other than the reference driver enum's, I've clearly marked
+      sections of the code and retained the copyright of the
+      respective owners.

Subject: [PATCH 601/869] V4L/DVB (7880): saa7134: remove explicit GPIO
 initialization

This causes a problem with the audio mute on some cards and is done
implictly in the audio initialization code.

Upon error conditions in cx18/ivtv_probe(), the code at the 'err:' label
leaves a NULL entry in cx18/ivtv_cards[]. This can cause a NULL pointer
de-reference in cx18/ivtv_v4l2_open() which is fixed by this patch.

From 48723543aff1f46091840222490ded5fe09c0e37 Mon Sep 17 00:00:00 2001

Subject: [PATCH 608/869] V4L/DVB (7893): xc5000: bug-fix: allow multiple
 devices in a single system

The current code passes a context pointer in the xc5000_config struct.
This context pointer is used in the tuner_callback function, used to
reset the device after firmware download.

The xc5000_config struct is a static structure, whose .priv member was
being assigned before calling xc5000_attach().  If there are more than
one of the same device type installed on a single system, the last one
to assign xc5000_config.priv will "win", and all others will cease to
function properly.

This patch passes the context pointer in xc5000_attach() rather that
storing it within the static struct xc5000_config.

Subject: [PATCH 610/869] V4L/DVB (7898): Fix VIDEO_MEDIA Kconfig logic

If one of DVB_CORE or VIDEO_DEV is a module, the modules that can be used by
both DVB and V4L cores should also be a module, otherwise, it will break its
dependencies. This Kconfig logic implements the following:

CONFIG_VIDEO_DEV        CONFIG_DVB_CORE         CONFIG_VIDEO_MEDIA
        N                       N                       N
        N                       M                       M

 at common/tuners

- MEDIA_ATTACH now applies also for V4L;

- select a FW_LOADER dependent driver should happen only if HOTPLUG;

- apply the common tuner dependency to all tuners. This helps to avoid latter
  issues.

Subject: [PATCH 613/869] cipso: Relax too much careful cipso hash function.

The cipso_v4_cache is allocated to contain CIPSO_V4_CACHE_BUCKETS
buckets. The CIPSO_V4_CACHE_BUCKETS = 1 << CIPSO_V4_CACHE_BUCKETBITS,
where CIPSO_V4_CACHE_BUCKETBITS = 7.

The bucket-selection function for this hash is calculated like this:

  bkt = hash & (CIPSO_V4_CACHE_BUCKETBITS - 1);
                                     ^^^

i.e. picking only 4 buckets of possible 128 :)

 messages

Conntrack ID is not put (anymore ?) in event messages. This causes
current ulogd2 code to fail because it uses the ID to build a hash in
userspace. This hash is used to be able to output the starting time of
a connection.

Conntrack ID can be used in userspace application to maintain an easy
match between kernel connections list and userspace one. It may worth
to add it if there is no performance related issue.

[ Patrick: it was never included in events, but really should be ]

Subject: [PATCH 621/869] USB: create attributes before sending uevent

This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.

Unfortunately there are a few attributes which cannot be created that
early.  The "descriptors" attribute is binary and so must be created
separately.  The power-management attributes can't be created until
the dev/power/ group exists.  And the interface string can vary from
one altsetting to another, so it has to be created dynamically.

the proposed patch allows the ET502HS HDSPA modem to be handled by the
"option" driver. It has been tested for 1 month and works reliably (no
oopses, no hangs, 300KB/s throughput).

Subject: [PATCH 628/869] USB: add Zoom Telephonics Model 3095F V.92 USB Mini
 External modem to cdc-acm

The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:

May  3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May  3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22

Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

From: Eugeniy Meshcheryakov <eugen@debian.org>
Date: Mon, 5 May 2008 01:24:38 +0200
Subject: [PATCH 630/869] USB: do not handle device 1410:5010 in 'option'
 driver

This device is not a serial port, but a virtual CD-ROM device. For
example with my Novatel MC950D:

lsusb -v -d 1410:5010 | grep InterfaceClass
      bInterfaceClass         8 Mass Storage

After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:

% lsusb -v -d 1410:4400 | grep InterfaceClass
      bInterfaceClass       255 Vendor Specific Class
      bInterfaceClass       255 Vendor Specific Class

Variable name says that 0x5010 is a Novatel U727, but searching in
internet shows, that this device also provides virtual CD that should be
ejected before use. Product id for serial port in this case is 0x4100.

Subject: [PATCH 632/869] USB: serial gadget: cleanup/reorg

Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.

 - Remove most forward declarations
     * put tty and gadget driver structs after their contents
     * snug module init/exit decls next to their functions
     * reordered some functions

 - Other cleanup:
     * convert a funky macro to an inline function
     * snug up module params next to their declarations
     * add missing driver.owner
     * add separator lines between major driver sections

 - Add comments re potential parameter/#define changes:
     * only supports one port (shrank GS_NUM_PORTS)
     * changing from 9600-8-N-1 affects multiple sites

 - Remove net2280-specific optimization ... it was being done
   way too late, can be done by net2280 module options, and in
   any case doesn't matter at any sane serial data rates.

There are no behavioral changes, but the macro thing saves I-space.

Subject: [PATCH 633/869] USB: serial gadget: remove needless data structure

This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.

Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

Subject: [PATCH 634/869] USB: serial gadget: simplify endpoint handling

Switch serial gadget away from a *very* old idiom:  just remember
the endpoints we'll be using, instead of looking them up by name
each time.  This is a net code and data (globals) shrink.

Also fix a small memory leak in the rmmod path, by working the
same as the disconnect code.

Subject: [PATCH 635/869] USB: serial gadget: descriptor cleanup

Bugfix some serial gadget descriptors:

 - Stop mangling the low bits (controller type ID) of bcdDevice;
   just use the high bits for a driver revision code.

 - Serial numbers that aren't specific to individual devices
   are useless; stop reporting "0" for this.

 - Since it's not part of a CDC-conformant function, the "bulk only"
   configuration shouldn't be using "CDC Data" as its interface class.
   Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).

Subject: [PATCH 636/869] USB: unusual_devs: Add support for GI 0401 SD-Card
 interface

Enables the SD-Card interface on the GI 0401 HSUPA card from Option.

The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an
interface driver.

This revised patch adds a small comment explaining why and reduces the
rev range.

Subject: [PATCH 638/869] USB: remove PICDEM FS USB demo (04d8:000c) device
 from ldusb

Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
to use bulk transfer and not interrupt transfer. So I've updated the libusb
based program here (Post #31).
	http://forum.microchip.com/tm.aspx?m=106426&mpage=2

So I believe that the in-kernel ldusb driver will no longer work with the
demo firmware.  It should be removed.

Subject: [PATCH 641/869] USB: atmel_usba_udc fixes, mostly disconnect()

Various fixes to Atmel's high speed UDC driver.

  * Issue some missing disconnect() calls.  Currently they are only made
    when VBUS power goes away (on boards where the driver can sense such
    changes), but that's not enough for gadget drivers to clean out all
    the state that's needed.  Missing calls were:

      - After USB reset, before starting enumeration.
      - When unregistering a gadget driver, before unbind().

  * Don't assume gadget drivers provide disconnect callbacks; make sure
    to not call through a null pointer!

  * When the driver doesn't provide an unbind() callback, refuse to
    unregister it.

Also remove two bogus "error" messages:

  * Related to mis-handling of disconnect() ... don't emit error messages
    for disconnect() handlers that disable endpoints.  All of them should
    be doing that; the problem is (unfixed) oddness in atmel_usba_udc.

  * Don't emit a diagnostic for a curious and transient nonfatal error
    that shows up sometimes with EP0.

Those messages spammed syslog, for no good reason.

Subject: [PATCH 643/869] fix SMP data race in pagetable setup vs walking

There is a possible data race in the page table walking code. After the split
ptlock patches, it actually seems to have been introduced to the core code, but
even before that I think it would have impacted some architectures (powerpc
and sparc64, at least, walk the page tables without taking locks eg. see
find_linux_pte()).

The race is as follows:
The pte page is allocated, zeroed, and its struct page gets its spinlock
initialized. The mm-wide ptl is then taken, and then the pte page is inserted
into the pagetables.

At this point, the spinlock is not guaranteed to have ordered the previous
stores to initialize the pte page with the subsequent store to put it in the
page tables. So another Linux page table walker might be walking down (without
any locks, because we have split-leaf-ptls), and find that new pte we've
inserted. It might try to take the spinlock before the store from the other
CPU initializes it. And subsequently it might read a pte_t out before stores
from the other CPU have cleared the memory.

There are also similar races in higher levels of the page tables. They
obviously don't involve the spinlock, but could see uninitialized memory.

Arch code and hardware pagetable walkers that walk the pagetables without
locks could see similar uninitialized memory problems, regardless of whether
split ptes are enabled or not.

I prefer to put the barriers in core code, because that's where the higher
level logic happens, but the page table accessors are per-arch, and open-coding
them everywhere I don't think is an option. I'll put the read-side barriers
in alpha arch code for now (other architectures perform data-dependent loads
in order).

Subject: [PATCH 644/869] block: do_mounts - accept root=<non-existant
 partition>

Some devices, like md, may create partitions only at first access,
so allow root= to be set to a valid non-existant partition of an
existing disk. This applies only to non-initramfs root mounting.

This fixes a regression from 2.6.24 which did allow this to happen and
broke some users machines :(

Subject: [PATCH 646/869] mmc: Fix omap compile by replacing dev_name with

This patch fixes error:

drivers/mmc/host/omap.c: In function 'mmc_omap_get_dma_channel':
drivers/mmc/host/omap.c:1038: error: called object 'dev_name' is not a function

Commit 06916639e2fed9ee475efef2747a1b7429f8fe76 adds a function
called dev_name. This will cause a name conflict as dev_dbg calls
dev_name(((host->mmc)->parent)).

This same issue should not affect other drivers as they don't seem
to use dev_name with dev_dbg.

Thanks to Paul Walmsley <paul@pwsan.com> for figuring this one out.

+ * Addressing Terminology
+ *
+ *	M       - The low M bits of a physical address represent the offset
+ *		  into the blade local memory. RAM memory on a blade is physically
+ *		  contiguous (although various IO spaces may punch holes in
+ *		  it)..
+ *
+ * 	N	- Number of bits in the node portion of a socket physical
+ * 		  address.
+ *
+ * 	NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
+ * 	 	  routers always have low bit of 1, C/MBricks have low bit
+ * 		  equal to 0. Most addressing macros that target UV hub chips
+ * 		  right shift the NASID by 1 to exclude the always-zero bit.
+ * 		  NASIDs contain up to 15 bits.
+ *
+ *	GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
+ *		  of nasids.
+ *
+ * 	PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
+ * 		  of the nasid for socket usage.
+ *
+ *
+ *  NumaLink Global Physical Address Format:
+ *  +--------------------------------+---------------------+
+ *  |00..000|      GNODE             |      NodeOffset     |
+ *  +--------------------------------+---------------------+
+ *          |<-------53 - M bits --->|<--------M bits ----->
+ *
+ *	M - number of node offset bits (35 .. 40)
+ *
+ *
+ *  Memory/UV-HUB Processor Socket Address Format:
+ *  +----------------+---------------+---------------------+
+ *  |00..000000000000|   PNODE       |      NodeOffset     |
+ *  +----------------+---------------+---------------------+
+ *                   <--- N bits --->|<--------M bits ----->
+ *
+ *	M - number of node offset bits (35 .. 40)
+ *	N - number of PNODE bits (0 .. 10)
+ *
+ *		Note: M + N cannot currently exceed 44 (x86_64) or 46 (IA64).
+ *		The actual values are configuration dependent and are set at
+ *		boot time. M & N values are set by the hardware/BIOS at boot.

From 8a3360f06cd4d3b1d57f73e029f2f8b6057fdcba Mon Sep 17 00:00:00 2001
From: Bernhard Walle <bwalle@suse.de>
Date: Wed, 14 May 2008 15:40:40 -0700
Subject: [PATCH 658/869] [IA64] Don't reserve crashkernel memory > 4 GB

Some IA64 machines map all cell-local memory above 4 GB (32 bit limit).
However, in most cases, the kernel needs some memory below that limit that is
DMA-capable. So in this machine configuration, the crashkernel will be reserved
above 4 GB.

For machines that use SWIOTLB implementation because they lack an I/O MMU
the low memory is required by the SWIOTLB implementation. In that case,
it doesn't make sense to reserve the crashkernel at all because it's unusable
for kdump.

A special case is the "hpzx1" machine vector. In theory, it has a I/O MMU, so
it can be booted above 4 GB. However, in the kdump case that is not possible
because of changeset 51b58e3e26ebfb8cd56825c4b396ed251f51dec9:

    On HP zx1 machines, the 'machvec=dig' parameter is needed for the kdump
    kernel to avoid problems with the HP sba iommu.  The problem is that during
    the boot of the kdump kernel, the iommu is re-initialized, so in-flight DMA
    from improperly shutdown drivers causes an IOTLB miss which leads to an
    MCA.  With kdump, the idea is to get into the kdump kernel with as little
    code as we can, so shutting down drivers properly is not an option.

    The workaround is to add 'machvec=dig' to the kdump kernel boot parameters.
    This makes the kdump kernel avoid using the sba iommu altogether, leaving
    the IOTLB intact.  Any ongoing DMA falls harmlessly outside the kdump
    kernel.  After the kdump kernel reboots, all devices will have been
    shutdown properly and DMA stopped.

This patch pushes that functionality into the sba iommu initialization
code, so that users won't have to find the obscure documentation telling
them about 'machvec=dig'.

This means that also for hpzx1 it's not possible to boot when all
memory is above the 4 GB limit. So the only machine vectors that can handle
this case are "sn2" and "uv".

Subject: [PATCH 659/869] [IA64] allow user to force_pal_cache_flush

The sequence executed in check_sal_cache_flush:

	- pend a timer interrupt
	- call SAL_CACHE_FLUSH
	- see if interrupt is still pending

can hang HP machines with buggy SAL_CACHE_FLUSH implementations.

Provide a kernel command-line argument to allow users skip this
check if desired. Using this parameter will force ia64_sal_cache_flush
to call ia64_pal_cache_flush() instead of SAL_CACHE_FLUSH.

Subject: [PATCH 660/869] [IA64] fix interrupt masking for pending works on
 kernel leave

[Bug-fix for "[BUG?][2.6.25-mm1] sleeping during IRQ disabled"]

This patch does:
 - enable interrupts before calling schedule() as same as others, ex. x86
 - enable interrupts during ia64_do_signal() and ia64_sync_krbs()
 - do_notify_resume_user() is still called with interrupts disabled, since
   we can take short path of fsys_mode if-statement quickly.
 - pfm_handle_work() is also called with interrupts disabled, since
   it can deal interrupt mask within itself.
 - fix/add some comments/notes

Subject: [PATCH 664/869] [IA64] Properly unregister legacy interrupts

acpi_unregister_gsi() should "undo" what acpi_register_gsi() does.

On systems that have legacy interrupts, acpi_unregister_gsi erroneously calls
iosapci_unregister_intr() which is wrong to do and causes a loud warning.

acpi_unregister_gsi() should just return in these cases.

Subject: [PATCH 665/869] add match_strlcpy() us it to make v9fs make uname and
 remotename parsing more robust

match_strcpy() is a somewhat creepy function: the caller needs to make sure
that the destination buffer is big enough, and when he screws up or
forgets, match_strcpy() happily overruns the buffer.

There's exactly one customer: v9fs_parse_options().  I believe it currently
can't overflow its buffer, but that's not exactly obvious.

The source string is a substing of the mount options.  The kernel silently
truncates those to PAGE_SIZE bytes, including the terminating zero.  See
compat_sys_mount() and do_mount().

The destination buffer is obtained from __getname(), which allocates from
name_cachep, which is initialized by vfs_caches_init() for size PATH_MAX.

We're safe as long as PATH_MAX <= PAGE_SIZE.  PATH_MAX is 4096.  As far as
I know, the smallest PAGE_SIZE is also 4096.

Here's a patch that makes the code a bit more obviously correct.  It
doesn't depend on PATH_MAX <= PAGE_SIZE.

Subject: [PATCH 668/869] 9p: propagate parse_option changes to client and
 transports

Propagate changes that were made to the parse_options code to the
other parse options pieces present in the other modules.  Looks like
the client parse options was probably corrupting the parse string
and causing problems for others.

Subject: [PATCH 671/869] 9p: fix flags length in net

Some files in the net/9p directory uses "int" for flags. This can
cause hard to find bugs on some architectures. This patch converts the
flags to use "long" instead.

This bug was discovered by doing an allyesconfig make on the -rt kernel
where checks are done to ensure all flags are of size sizeof(long).

Subject: [PATCH 672/869] 9p: make cryptic unknown error from server less scary

Right now when we get an error string from the server that we can't
map we report a cryptic error that actually makes it look like we are
reporting a problem with the client.  This changes the text of the log
message to clarify where the error is coming from.

Subject: [PATCH 673/869] 9p: fix error path during early mount

There was some cleanup issues during early mount which would trigger
a kernel bug for certain types of failure.  This patch reorganizes the
cleanup to get rid of the bad behavior.

This also merges the 9pnet and 9pnet_fd modules for the purpose of
configuration and initialization.  Keeping the fd transport separate
from the core 9pnet code seemed like a good idea at the time, but in
practice has caused more harm and confusion than good.

Subject: [PATCH 676/869] oprofile: don't request cache line alignment for
 cpu_buffer

Alignment was previously requested because cpu_buffer was an [NR_CPUS]
array, to avoid cache line sharing between CPUS.

After commit 608dfddd845da5ab6accef70154c8910529699f7 (oprofile: change
cpu_buffer from array to per_cpu variable ), we dont need to force an
alignement anymore since cpu_buffer sits in per_cpu zone.

Subject: [PATCH 677/869] fix "lxfb: extend PLL table to support dotclocks
 below 25 MHz"

The following patch caused a regression with OLPC panels:

 commit 3888d4639e78802c4ec1086127124e890461b9e4
    lxfb: extend PLL table to support dotclocks below 25 MHz

    Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
    make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
    MHz.  These are needed for small LCDs (e.g.  320x240).  Also inserts some
    intermediate steps between pre-existing frequencies.

The problem was the insertion of intermediate steps into the frequency
table; they would cause the wrong frequency to be matched.  This patch
drops those intermediate frequencies while keeping the sub-25MHz
frequencies.

The subsequent AD181x quirk patch would like this as part of the API.
pnp_register_dependent_option() adds to the same dependent chain the quirk is
walking which is fairly unclean.  This enables a private option chain build
which it can then just add onto the end when done.

Subject: [PATCH 680/869] pnp: add ISAPnP MPU option quirks

The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but
work fine without one.  This adds (priority functional) IRQ-less options
for each port option to help systems with few available IRQs.

The AD1815 quirk can't use pnp_register_irq_resource() due to doubly
penalizing the IRQ.  Also, while not a practical issue due to no IRQ
option being present for the dependents, this needs to add in front, not
back.

Doesn't use pnp_register_port_resource() for symetry with above.

This does not delete the AD1815 independent option even though it should
be empty after the IRQ transfer due to AD1816 coming with an empty but
still present independent option by default.

Was tested on AD1815, AD1816 and AZT2320.  The ALSA snd-ad1818a driver
also support the AZT2002 ID for MPU401 but this doesn't as I was unable to
test it.

Subject: [PATCH 681/869] mm: fix infinite loop in filemap_fault

filemap_fault will go into an infinite loop if ->readpage() fails
asynchronously.

AFAICS the bug was introduced by this commit, which removed the wait after the
final readpage:

   commit d00806b183152af6d24f46f0c33f14162ca1262a
   Author: Nick Piggin <npiggin@suse.de>
   Date:   Thu Jul 19 01:46:57 2007 -0700

       mm: fix fault vs invalidate race for linear mappings

Fix by reintroducing the wait_on_page_locked() after ->readpage() to make sure
the page is up-to-date before jumping back to the beginning of the function.

I've noticed this while testing nfs exporting on fuse.  The patch
fixes it.

Subject: [PATCH 682/869] atmel_lcdfb: fix initialization of a pre-allocated
 framebuffer

Fix initialization of framebuffer not calling ioremap_writecombine() function
and not using internal SRAM for at91sam9rl.

This is a little rework of the "Don't initialize a pre-allocated framebuffer"
patch that corrects the call to ioremap_writecombine() function.

It also cuts the use of internal SRAM for at91sam9rl : it is a bit small
for a framebuffer.

Subject: [PATCH 684/869] memory hotplug: memmap_init_zone called twice

__add_zone calls memmap_init_zone twice if memory gets attached to an empty
zone.  Once via init_currently_empty_zone and once explictly right after that
call.

Looks like this is currently not a bug, however the call is superfluous and
might lead to subtle bugs if memmap_init_zone gets changed.  So make sure it
is called only once.

Subject: [PATCH 686/869] asm-{alpha,h8300,um,v850,xtensa}/param.h: unbreak HZ
 for userspace

I noticed this because alpha was broken due to the recent commit commit
bdc807871d58285737d50dc6163d0feb72cb0dc2 ("avoid overflows in
kernel/time.c").  Most arches do something like this in their
asm/param.h:

#ifdef __KERNEL__
# define HZ CONFIG_HZ
#else
# define HZ 100
#endif

A few arches though (namely alpha/h8300/um/v850/xtensa) either do no set
HZ at all for !__KERNEL__, or they set it wrongly.  This should bring all
arches in line by setting up HZ for userspace.

Without this currently perl 5.10 doesn't build on alpha:

perl.c: In function 'perl_construct':
perl.c:388: error: 'CONFIG_HZ' undeclared (first use in this function)
-> http://buildd.debian.org/fetch.cgi?pkg=perl;ver=5.10.0-10;arch=alpha;stamp=1210252894

This fix the uninitialized bs when we try to replace a xattr entry in
ibody with the new value which require more than free space.

This situation only happens we format ext3/4 with inode size more than 128 and
we have put xattr entries both in ibody and block.  The consequences about
this bug is we will lost the xattr block which pointed by i_file_acl with all
xattr entires in it.  We will alloc a new xattr block and put that large value
entry in it.  The old xattr block will become orphan block.

Subject: [PATCH 690/869] lib: create common ascii hex array

Add a common hex array in hexdump.c so everyone can use it.

Add a common hi/lo helper to avoid the shifting masking that is
done to get the upper and lower nibbles of a byte value.

Pull the pack_hex_byte helper from kgdb as it is opencoded many
places in the tree that will be consolidated.

Add a check to online_pages() to test for failure of
walk_memory_resource().  This fixes a condition where a failure
of walk_memory_resource() can lead to online_pages() returning
success without the requested pages being onlined.

Subject: [PATCH 692/869] per_cpu: fix DEFINE_PER_CPU_SHARED_ALIGNED for
 modules

Current module loader lookups ".data.percpu" ELF section to perform
per_cpu relocation.  But DEFINE_PER_CPU_SHARED_ALIGNED() uses another
section (".data.percpu.shared_aligned"), currently only handled in
vmlinux.lds, not by module loader.

To correct this problem, instead of adding logic into module loader, or
using at build time a module.lds file for all arches to group
".data.percpu.shared_aligned" into ".data.percpu", just use ".data.percpu"
for modules.

Alignment requirements are correctly handled by ld and module loader.

Subject: [PATCH 694/869] memory_hotplug: always initialize pageblock bitmap

Trying to online a new memory section that was added via memory hotplug
sometimes results in crashes when the new pages are added via __free_page.
 Reason for that is that the pageblock bitmap isn't initialized and hence
contains random stuff.  That means that get_pageblock_migratetype()
returns also random stuff and therefore

	list_add(&page->lru,
		&zone->free_area[order].free_list[migratetype]);

in __free_one_page() tries to do a list_add to something that isn't even
necessarily a list.

This happens since 86051ca5eaf5e560113ec7673462804c54284456 ("mm: fix
usemap initialization") which makes sure that the pageblock bitmap gets
only initialized for pages present in a zone.  Unfortunately for hot-added
memory the zones "grow" after the memmap and the pageblock memmap have
been initialized.  Which means that the new pages have an unitialized
bitmap.  To solve this the calls to grow_zone_span() and grow_pgdat_span()
are moved to __add_zone() just before the initialization happens.

The patch also moves the two functions since __add_zone() is the only
caller and I didn't want to add a forward declaration.

Subject: [PATCH 696/869] Remove blkdev warning triggered by using md

As setting and clearing queue flags now requires that we hold a spinlock
on the queue, and as blk_queue_stack_limits is called without that lock,
get the lock inside blk_queue_stack_limits.

For blk_queue_stack_limits to be able to find the right lock, each md
personality needs to set q->queue_lock to point to the appropriate lock.
Those personalities which didn't previously use a spin_lock, us
q->__queue_lock.  So always initialise that lock when allocated.

With this in place, setting/clearing of the QUEUE_FLAG_PLUGGED bit will no
longer cause warnings as it will be clear that the proper lock is held.

Thanks to Dan Williams for review and fixing the silly bugs.

Subject: [PATCH 700/869] [POWERPC] vmemmap fixes to use smaller pages

This changes vmemmap to use a different region (region 0xf) of the
address space, and to configure the page size of that region
dynamically at boot.

The problem with the current approach of always using 16M pages is that
it's not well suited to machines that have small amounts of memory such
as small partitions on pseries, or PS3's.

In fact, on the PS3, failure to allocate the 16M page backing vmmemmap
tends to prevent hotplugging the HV's "additional" memory, thus limiting
the available memory even more, from my experience down to something
like 80M total, which makes it really not very useable.

The logic used by my match to choose the vmemmap page size is:

 - If 16M pages are available and there's 1G or more RAM at boot,
   use that size.
 - Else if 64K pages are available, use that
 - Else use 4K pages

I've tested on a POWER6 (16M pages) and on an iSeries POWER3 (4K pages)
and it seems to work fine.

Note that I intend to change the way we organize the kernel regions &
SLBs so the actual region will change from 0xf back to something else at
one point, as I simplify the SLB miss handler, but that will be for a
later patch.

Subject: [PATCH 701/869] [POWERPC] Add null pointer check to of_find_property

Update function of_find_property() to return NULL if the device_node
passed to it is also NULL.  Otherwise, passing NULL will cause a null
pointer dereference.

Without this, the legacy_serial driver will crash if there's no
'chosen' node in the device tree.

Subject: [PATCH 702/869] [POWERPC] Fix uninitialized variable bug in
 copy_{to|from}_user

Calls to copy_to_user() or copy_from_user() can fail when copying N
bytes, where N is a constant less than 8, but not 1, 2, 4, or 8,
because 'ret' is not initialized and is only set if the size is 1,
2, 4 or 8, but is tested after the switch statement for any constant
size <= 8.  This fixes it by initializing 'ret' to 1, causing the
code to fall through to the __copy_tofrom_user call for sizes other
than 1, 2, 4 or 8.

Subject: [PATCH 710/869] parisc: remove redundant display of free swap space
 in show_mem()

show_mem() has no need to print the amount of free swap space manually because
show_free_areas() does this already and is called by the former.

The two outputs only differ in text formatting:

  printk("Free swap  = %lukB\n", ...);
  printk("Free swap:       %6ldkB\n", ...);

 handler

When the dasd_int_handler is called with an error code instead of
an irb, the associated request should be restarted. This handling
was missing from the -ETIMEDOUT case. In fact it should be done in
any case.

Subject: [PATCH 721/869] [S390] smp: __smp_call_function_map vs cpu_online_map
 fix.

Both smp_call_function() and __smp_call_function_map() access
cpu_online_map. Both functions run with preemption disabled which
protects for cpus going offline. However new cpus can be added and
therefore the cpu_online_map can change unexpectedly.
So use the call_lock to protect against changes to the cpu_online_map
in start_secondary() and all smp_call_* functions.

Subject: [PATCH 727/869] [IA64] fix personality(PER_LINUX32) performance issue

The patch aims to fix a performance issue for the syscall
personality(PER_LINUX32).

On IA-64 box, the syscall personality (PER_LINUX32) has poor performance
because it failed to find the Linux/x86 execution domain. Then it tried
to load the kernel module however it failed always and it used the default
execution domain PER_LINUX instead. Requesting kernel modules is very
expensive. It caused the performance issue. (see the function
lookup_exec_domain in kernel/exec_domain.c).

To resolve the issue, execution domain Linux/x86 is always registered in
initialization time for IA-64 architecture.

Subject: [PATCH 728/869] tty: fix BKL related leak and crash

Enabling the BKL to be lockdep tracked uncovered the following
upstream kernel bug in the tty code, which caused a BKL
reference leak:

  ================================================
  [ BUG: lock held when returning to user space! ]
  ------------------------------------------------
  dmesg/3121 is leaving the kernel with locks still held!
  1 lock held by dmesg/3121:
   #0:  (kernel_mutex){--..}, at: [<c02f34d9>] opost+0x24/0x194

this might explain some of the atomicity warnings and crashes
that -tip tree testing has been experiencing since the BKL
was converted back to a spinlock.

Subject: [PATCH 729/869] ext4: Retry block allocation if new blocks are
 allocated from system zone.

If the block allocator gets blocks out of system zone ext4 calls
ext4_error. But if the file system is mounted with errors=continue
retry block allocation. We need to mark the system zone blocks as
in use to make sure retry don't pick them again

System zone is the block range mapping block bitmap, inode bitmap and inode
table.

Everybody wants to pass it a function pointer, and in fact, that is what
you _must_ pass it for it to make sense (since it knows that ia64 and
ppc64 use descriptors for function pointers and fetches the actual
address from there).

So don't make the argument be a 'unsigned long' and force everybody to
add a cast.

Date: Thu, 15 May 2008 13:52:41 -0700
Subject: [PATCH 733/869] initcalls: Fix m68k build and possible buffer
 overflow

This patch fixes a build bug on m68k - gcc decides to emit a call to the
strlen library function, which we don't implement.

More importantly - my previous patch "init: don't lose initcall return
values" (commit e662e1cfd434aa234b72fbc781f1d70211cb785b) had introduced
potential buffer overflow by wrong calculation of string accumulator
size.

Use strlcat() instead, fixing both bugs.

Many thanks Andreas Schwab and Geert Uytterhoeven for helping
to catch and fix the bug.

Subject: [PATCH 735/869] sh: disable initrd defaults in .empty_zero_page.

When using initramfs on systems that don't explicitly clear LOADER_TYPE,
unpack_to_rootfs() tramples tramples the range with the defaults taken
out of .empty_zero_page. This causes kernels with valid initramfs images
to bail out with crc or gzip magic mismatch errors after the second
unpack takes place on certain platform configurations.

Subject: [PATCH 740/869] NFS: Ensure that 'noac' and/or 'actimeo=0' turn off
 attribute caching

Both the 'noac' and 'actimeo=0' mount options should ensure that attributes
are not cached, however a bug in nfs_attribute_timeout() means that
currently, the attributes may in fact get cached for up to one jiffy. This
has been seen to cause corruption in some applications.

The reason for the bug is that the time_in_range() test returns 'true' as
long as the current time lies between nfsi->read_cache_jiffies and
nfsi->read_cache_jiffies + nfsi->attrtimeo. In other words, if jiffies
equals nfsi->read_cache_jiffies, then we still cache the attribute data.

Subject: [PATCH 742/869] NFSv4: Check the return value of
 decode_compound_hdr_arg()

If decode_compound_hdr_arg() returns a resource error, then we cannot
proceed to process the callback. Return a 'GARBAGE_ARGS' rpc-level error to
the caller instead.
If, however, the minor version field is incorrect, then we need to
propagate the resulting NFS4ERR_MINOR_VERS_MISMATCH error back as the
compound status field (setting the nops field to 0).

Finally, if encode_compound_hdr_res() returns an error, we need to return
an RPC_SYSTEM_ERR to the caller.

Subject: [PATCH 743/869] nfs/lsm: make NFSv4 set LSM mount options

NFSv3 get_sb operations call into the LSM layer to set security options passed
from userspace.  NFSv4 hooks were not originally added since it was reasonably
late in the merge window and NFSv3 was the only thing that had regressed (v4
has never supported any LSM options)

This patch makes NFSv4 call into the LSM to set security options rather than
just blindly dropping them with no notice to the user as happens today.  This
patch was tested in a simple NFSv4 environment with the context= option and
appeared to work as expected.

From 7047901ec7d6eca97cf66f54b8a4197bb0754f40 Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@davemloft.net>
Date: Wed, 14 May 2008 23:10:33 -0700
Subject: [PATCH 748/869] sparc64: Fix lmb_reserve() args in find_ramdisk().

This fixes the missing ram regression reported by
Mikael Pettersson <mikpe@it.uu.se>, much thanks for
all of this help in diagnosing this.

The second argument to lmb_reserve() is a size,
not an end address bounds.

Tested-by: Mikael Pettersson <mikpe@it.uu.se>

Date: Thu, 8 May 2008 21:02:45 -0400
Subject: [PATCH 752/869] [PATCH] dup_fd() part 2

use alloc_fdtable() instead of expand_files(), get rid of pointless
grabbing newf->file_lock, kill magic in copy_fdtable() that used to
be there only to skip copying when called from dup_fd().

Subject: [PATCH 754/869] [PATCH] dup_fd() part 4 - race fix

Parent _can_ be a clone task, contrary to the comment.  Moreover,
more files could be opened while we allocate a copy, in which case
we end up copying only part into new descriptor table.  Since what
we get _is_ affected by all changes in the old range, we can get
rather weird effects - e.g.
	dup2(0, 1024); close(0);
in parallel with fork() resulting in child that sees the effect of
close(), but not that of dup2() done just before that close().

What we need is to recalculate the open_count after having reacquired
->file_lock and if external fdtable we'd just allocated is too small for
it, free the sucker and redo allocation.

In kmalloc failing path, we shouldn't free pointers in 'info',
because the struct 'info' is uninitilized when kmalloc is called.

And when kmalloc returns NULL, it's needless to kfree it.

Even though copy_compat_strings() doesn't cache the pages,
copy_strings_kernel() and stuff indirectly called by e.g.
->load_binary() is doing that, so we need to drop the

	In case when both EEXIST and EROFS would apply we used to

us of being consistent, in the same situation knfsd gave clients
nfs_erofs...

	ro-bind series had switched the syscall side of things to
returning -EROFS and immediately broke an application - namely,
mkdir -p.  Patch restores the original behaviour...

Subject: [PATCH 771/869] 8250 Serial Driver: Added support for 8250-class
 UARTs in HV Sistemas H8606 board

Added support for 8250-class UARTs in HV Sistemas H8606 board,
modification in 8250.c driver for correct compilation with Blackfin

Besides, I think that there is more people using 8250-class UARTs
with a different hardware than the H8606 board. This code can be shared
by them.

Subject: [PATCH 775/869] x86: remove mwait capability C-state check

Vegard Nossum reports:

| powertop shows between 200-400 wakeups/second with the description
| "<kernel IPI>: Rescheduling interrupts" when all processors have load (e.g.
| I need to run two busy-loops on my 2-CPU system for this to show up).
|
| The bisect resulted in this commit:
|
| commit 0c07ee38c9d4eb081758f5ad14bbffa7197e1aec
| Date:   Wed Jan 30 13:33:16 2008 +0100
|
|     x86: use the correct cpuid method to detect MWAIT support for C states

remove the functional effects of this patch and make mwait unconditional.

A future patch will turn off mwait on specific CPUs where that causes
power to be wasted.

Subject: [PATCH 776/869] x86: fix crash on cpu hotplug on pat-incapable
 machines

pat_disable() is __init, which means it goes away after booting is complete.
Unfortunately it is used by the hotplug code if the machine is not
pat-capable, causing a crash.

Fix by marking pat_disable() as __cpuinit.

Subject: [PATCH 777/869] x86: disable mwait for AMD family 10H/11H CPUs

The previous revert of 0c07ee38c9d4eb081758f5ad14bbffa7197e1aec left
out the mwait disable condition for AMD family 10H/11H CPUs.

Andreas Herrman said:

It depends on the CPU. For AMD CPUs that support MWAIT this is wrong.
Family 0x10 and 0x11 CPUs will enter C1 on HLT. Powersavings then
depend on a clock divisor and current Pstate of the core.

If all cores of a processor are in halt state (C1) the processor can
enter the C1E (C1 enhanced) state. If mwait is used this will never
happen.

Thus HLT saves more power than MWAIT here.

It might be best to switch off the mwait flag for these AMD CPU
families like it was introduced with commit
f039b754714a422959027cb18bb33760eb8153f0 (x86: Don't use MWAIT on AMD
Family 10)

Re-add the AMD families 10H/11H check and disable the mwait usage for
those.

Subject: [PATCH 780/869] [ARM] 5034/1: fix arm{925,926,940,946}
 dma_flush_range() in WT mode

The CPU's dma_flush_range() operation needs to clean+invalidate the
given memory area if the cache is in writeback mode, or do just the
invalidate part if the cache is in writethrough mode, but the current
proc-arm{925,926,940,946} (incorrectly) do a cache clean in the
latter case.  This patch fixes that.

Subject: [PATCH 781/869] [ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI
 initialisation

Whereas most Orion 5x machine support code would initialise the PCI
subsystem with nr_controllers in their struct hw_pci set to 2, the
DNS323 and Kurobox Pro machine support code had nr_controllers set
to 1.

This was presumably done because on those two machines, the PCI(-X)
controller (nr == 1) isn't used, requiring initialisation of only
the PCIe controller (nr == 0.)  However, not initialising the PCI(-X)
controller on boards that don't use it leads to a situation where
both the PCIe and the PCI(-X) controller think that their root bus is
zero, and it messes up IRQ assignment.

This patch changes the DNS323 and Kurobox Pro support code to always
use nr_controllers == 2.

Subject: [PATCH 787/869] KVM: x86 emulator: fix writes to registers with modrm
 encodings

A register destination encoded with a mod=3 encoding left dst.ptr NULL.
Normally we don't trap writes to registers, but in the case of smsw, we do.

Fix by pointing dst.ptr at the destination register.

 position-dependent objects

The GVMM module is position independent since it is relocated to the guest
address space.

Commit ea696f9cf ("ia64 kvm fixes for O=... builds") broke this by linking
GVMM with non-PIC objects.

Fix by creating two files: memset.S and memcpy.S which just include the files
under arch/ia64/lib/{memset.S, memcpy.S} respectively.

[akpm: don't delete files which we need]

CPU0                            CPU1

kvm_vcpu_block

add_wait_queue

kvm_cpu_has_interrupt = 0
                                set interrupt
                                if (waitqueue_active())

kvm_cpu_has_pending_timer
kvm_arch_vcpu_runnable
signal_pending

set_current_state(TASK_INTERRUPTIBLE)
schedule()

Can be fixed by using prepare_to_wait() which sets the task state before
testing for the wait condition.

Subject: [PATCH 798/869] i2c-nforce2: Disable the second SMBus channel on the
 DFI Lanparty NF4 Expert

There is a strange chip at 0x2e on the second SMBus channel of the
DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the
system. As there's nothing interesting on this SMBus channel, the
easiest and safest thing to do is to disable it on that board.

This is a better fix to bug #5889 than the it87 driver update that was
done originally:
http://bugzilla.kernel.org/show_bug.cgi?id=5889

Subject: [PATCH 801/869] i2c: Convert remaining new-style drivers to use
 module aliasing

Update all the remaining new-style i2c drivers to use standard module
aliasing instead of the old driver_name/type driver matching scheme.

Note that the tuner driver is a bit quirky at the moment, as it
overwrites i2c_client.name with arbitrary strings. We write "tuner"
back on remove, to make sure that driver cycling will work properly,
but there may still be troublesome corner cases.

Subject: [PATCH 804/869] i2c/max6875: Really prevent 24RF08 corruption

i2c-core takes care of the possible corruption of 24RF08 chips for
quite some times, so device devices no longer need to do it. And they
really should not, as applying the prevention twice voids it.

I thought that I had fixed all drivers long ago but apparently I had
missed that one.

device is found is -ENODEV, not -ENXIO or -EIO.

Subject: [PATCH 817/869] m68k: Q40/Q60 floppy support is broken

Mark Q40/Q60 floppy support broken:

    arch/m68k/q40/q40ints.c: In function 'q40_irq_handler':
    arch/m68k/q40/q40ints.c:214: error: implicit declaration of function 'floppy_hardint'

Including <asm/floppy.h> doesn't help, as it causes a lot of additional error
messages (cfr. Sun 3x).

Subject: [PATCH 819/869] m68k: Prefix ISA type with ISA_TYPE_

The *_ISA type defines are quite generic and cause namespace conflicts
(e.g. with `AMIGAHW_DECLARE(GG2_ISA)' in <asm/amigahw.h>) for some kernel
configurations. Use ISA_TYPE_* to avoid such conflicts.

From 026bf9bbcf88f31ea619eb46cf9d62beade00821 Mon Sep 17 00:00:00 2001
From: Geert Uytterhoeven <geert@linux-m68k.org>
Date: Sun, 18 May 2008 20:47:24 +0200
Subject: [PATCH 822/869] m68k: Add multi_defconfig

Add multi_defconfig, to build a kernel for all supported m68k platforms,
excluding Sun 3 (Sun 3 kernels are incompatible with all other m68k platforms)

Subject: [PATCH 824/869] snd-pcsp: adjust help texts to frighten users

Added the warning text to the help of snd-pcsp about the possible problem
with this driver so that user can know of the problem in advance.

Also, removed the obsoleted text about ancient pc-speaker patch in
CONFIG_SOUND help.

Subject: [PATCH 825/869] snd-pcsp: put back the compatibility code for the
 older alsa-libs

The attached patch adds back the compatibility code, allowing the
driver to work with older alsa-libs.
The removal was premature, it breaks the real-life configs.

CONFIG_EXPERIMENTAL looks like the only safe way to get out
of all the troubles at one go. :)

It appears that alsa allows a sound buffer with size not

snd-pcsp and floods the log. As a quick fix, the warning should
be disabled.

Currently is_valid_bugaddr() is true for anything >= PAGE_OFFSET, which
happens to be 0 on nommu configurations. Make this a bit smarter by just
reading in the opcode and comparing it against the trap type that we
already know. Follows the logic from avr32.

Subject: [PATCH 829/869] sh: Fix up restorer in debug_trap exception return
 path.

There are a few different types of debug trap exceptions, though now
that they are all going through a special jump table, the restorer needs
to be unified as well.

Presently this is falling through the ret_from_fork path, which more or
less does the right thing on SH-3/4 whilst being completely unsuitable on
MMU-less targets.

Ultimately what we want here is a branch through the platform's
restore_all directly, without worrying about the retval being clobbered.
We can accomplish that through a branch to __restore_all directly, so
switch it so we come back from the jump table and branch to the restorer.

This fixes up a recursion in the nommu WARN_ON() path, as well as some
other userspace nastiness where said recursion caused serious stack
corruption.

Subject: [PATCH 830/869] [POWERPC] 4xx: Workaround for CHIP_11 Errata

The PowerPC 440EP, 440GR, 440EPx, and 440GRx chips have an issue that
causes the PLB3-to-PLB4 bridge to wait indefinitely for transaction
requests that cross the end-of-memory-range boundary.  Since the DDR
controller only returns the valid portion of a read request, the bridge
will prevent other PLB masters from completing their transactions.

This implements the recommended workaround for this errata for chips that
use older versions of firmware that do not already handle it.  The last
4KiB of memory are hidden from the kernel to prevent the problem
transactions from occurring.

0000000000000bce N DW.task_io_accounting.h.8d8de327.0
0000000000000bec N DW.hrtimer.h.c23659c6.0

in his System.map / kallsyms output.

Simple solution is to skip all debugging
symbols (they are marked 'N').

 terminate sequence.

Set ATAPI host state machine to control IDE device terminate sequence.
Some IDE harddisk may assert terminate sequence in the middle of a
formal DMA transaction and resume later. Bit DETECT_TERM in ATAPI_CTRL
register determines whether the ATAPI host state machine or the kernel
driver should take care of this case.

Fix handling of the FIS_IRQ_CAUSE register in sata_mv.

This register exists *only* on GenIIe devices, so don't bother
writing to it on older chips.  Also, it has to be read/cleared
in mv_err_intr() before clearing the main ERR_IRQ_CAUSE register.

This keeps sata_mv from getting stuck forever on certain error types.

Subject: [PATCH 845/869] sata_mv: async notify for genIIe only

Now that we handle the FIS_IRQ_CAUSE register correctly,
we can also now handle SATA asynchronous notification events.

So enable them, but only for the more modern GenIIe chips.
(older chips have unaddressed errata issues related to this).

This fixes hot plug/unplug for port-muliplier ports.

Part one of simplifying/fixing handling of the main_irq_mask register
to resolve unexpected interrupt issues observed in 2.6.26-rc*.

Don't blindly enable port IRQs at host init time.
Instead, enable only the bits that we want,
which in this case is simply the PCI_ERR bit.

The per-port bits can wait until the ports are reset/probed for devices.

Subject: [PATCH 848/869] sata_mv: fix pmp drives not found

Part three of simplifying/fixing handling of the main_irq_mask register
to resolve unexpected interrupt issues observed in 2.6.26-rc*.

Partially fix a reported bug whereby we sometimes miss seeing drives on
a port-multiplier, as reported by Gwendal Grignou <gwendal@google.com>.

The problem was that we were receiving unexpected interrupts
during EH from POLLed commands while accessing port-multiplier registers.
These unexpected interrupts can be prevented by masking the DONE_IRQ bit
for the port whenever not operating in EDMA mode.

Also fix port_stop() to mask all port interrupts.

Subject: [PATCH 850/869] sata_mv: cache main_irq_mask register in hpriv

Part five of simplifying/fixing handling of the main_irq_mask register
to resolve unexpected interrupt issues observed in 2.6.26-rc*.

Keep a cached copy of the main_irq_mask so that we don't have
to stall the CPU to read it on every pass through mv_interrupt.

This significantly speeds up interrupt handling, both for sata_mv,
and for any other driver/device sharing the same PCI IRQ line.

Subject: [PATCH 851/869] sata_mv: ensure empty request queue for FBS-NCQ EH

Check for an empty request queue before stopping EDMA after a FBS-NCQ error,
as per recommendation from the Marvell datasheet.

This ensures that the EDMA won't suddenly become active again
just after our subsequent check of the empty/idle bits.

Also bump DRV_VERSION.

Subject: [PATCH 853/869] sata_promise: fix irq clearing buglets

This patch fixes two bugs in sata_promise's irq status clearing paths:
1. When clearing the irq status for a specific port, the driver
   read the global SEQMASK register. This is wrong because that
   clears the irq status for _all_ ports.
2. pdc_thaw() incorrectly added the PDC_INT_SEQMASK host register
   offset to a per-port ata engine base address. This resulted in
   it reading the unrelated PDC_PKT_SUBMIT register, which did not
   have the desired irq status clearing effect.

In both cases the fix is to read from the port's Command/Status
register. This also matches what Promise's own driver does.

Subject: [PATCH 854/869] sata_promise: mmio access cleanups

This patch cleans up sata_promise's mmio accesses.

In sata_promise there are three distinct mmio address spaces:
1. global registers, offsets from host->iomap[PDC_MMIO_BAR]
2. per-port ATA registers, offsets from ap->ioaddr.cmd_addr
3. per-port SATA registers, offsets from ap->ioaddr.scr_addr

The driver currently often fails to indicate which address space
a given mmio base pointer refers to, which is a source of bugs
and confusion (see recent pdc_thaw() irq clearing bug; it's also
been an obstacle for the pending NCQ extensions).

To reduce these problems, adopt a coding style where the name of
a base pointer always indicates which address space it refers to:
1. global registers: host_mmio
2. per-port ATA registers: ata_mmio
3. per-port SATA registers: sata_mmio

Also rearrange register offset definitions to clearly indicate
which address space they belong to, and add a symbolic definition
for the previously hard-coded PHYMODE4 register.

Subject: [PATCH 855/869] sata_promise: other cleanups

Minor coding-style fixes for sata_promise:
- remove stray blank lines
- fix checkpatch.pl errors; warnings about long lines
  remain, but I don't intend to address those at this time
- remove two inline directives: neither is essential and
  both functions are trivially inlinable anyway by virtue
  of being static and having a single unique call site
- fix comment in pdc_interrupt(): the bits in PDC_INT_SEQMASK
  denote SEQIDs not tags, the distinction becomes important
  when NCQ gets implemented

Subject: [PATCH 856/869] libata: fix sata_link_hardreset() @online out
 parameter handling

The @online out parameter is supposed to set to true iff link is
online and reset succeeded as advertised in the function description
and callers are coded expecting that.  However, sata_link_reset()
didn't behave this way on device readiness test failure.  Fix it.

Subject: [PATCH 857/869] libata: reorganize ata_eh_reset() no reset method
 path

Reorganize ata_eh_reset() such that @prereset() is called even when no
reset method is available and if block is used instead of goto to skip
actual reset.  This makes no reset case behave better (readiness wait)
and future changes easier.

Subject: [PATCH 858/869] libata: move reset freeze/thaw handling into
 ata_eh_reset()

Previously reset freeze/thaw handling lived outside of ata_eh_reset()
mainly because the original PMP reset code needed the port frozen
while resetting all the fan-out ports, which is no longer the case.

This patch moves freeze/thaw handling into ata_eh_reset().
@prereset() and @postreset() are now called w/o freezing the port
although @prereset() an be called frozen if the port is frozen prior
to entering ata_eh_reset().

This makes code simpler and will help removing hotplug event related
races.

Subject: [PATCH 859/869] libata: kill hotplug related race condition

Originally, whole reset processing was done while the port is frozen
and SError was cleared during @postreset().  This had two race
conditions.  1: hotplug could occur after reset but before SError is
cleared and libata won't know about it.  2: hotplug could occur after
all the reset is complete but before the port is thawed.  As all
events are cleared on thaw, the hotplug event would be lost.

Commit ac371987a81c61c2efbd6931245cdcaf43baad89 kills the first race
by clearing SError during link resume but before link onlineness test.
However, this doesn't fix race #2 and in some cases clearing SError
after SRST is a good idea.

This patch solves this problem by cross checking link onlineness with
classification result after SError is cleared and port is thawed.
Reset is retried if link is online but all devices attached to the
link are unknown.  As all devices will be revalidated, this one-way
check is enough to ensure that all devices are detected and
revalidated reliably.

This, luckily, also fixes the cases where host controller returns
bogus status while harddrive is spinning up after hotplug making
classification run before the device sends the first FIS and thus
causes misdetection.

Low level drivers can bypass the logic by setting class explicitly to
ATA_DEV_NONE if ever necessary (currently none requires this).

Subject: [PATCH 860/869] libata: ignore recovered PHY errors

No reason to get overzealous about recovered comm and data errors.
Some PHYs habitually sets them w/o no good reason and being draconian
about these soft error conditions doesn't seem to help anybody.

If need ever rises, we might need to add soft PHY error condition, say
AC_ERR_MAYBE_ATA_BUS and use it only to determine whether speed down
is necessary but I don't think that's very likely to happen.  It's far
more likely we'll get timeouts or fatal transmission errors if
recovered errors are so prominent that they hamper operation.

Subject: [PATCH 861/869] libata: increase PMP register access timeout to 3s

This timeout was set low because previously PMP register access was
done via polling and register access timeouts could stack up.  This is
no longer the case.  One timeout will make all following accesses fail
immediately.

In rare cases both marvell and SIMG PMPs need almost a second.  Bump
it to 3s.

While at it, rename it to SATA_PMP_RW_TIMEOUT.  It's not specific to
SCR access.

Subject: [PATCH 862/869] libata: make sure PMP notification is turned off
 during recovery

PMP notification during reset can make some controllers fail reset
processing and needs to be turned off during resets.  PMP attach and
full-revalidation path did this via sata_pmp_configure() but the quick
revalidation wasn't.  Move the notification disable code right above
fan-out port recovery so that it's always turned off.

This fixes obscure reset failures.

Subject: [PATCH 864/869] sata_sil24: don't use NCQ if marvell 4140 PMP is
 attached

When 4140 PMP is attached to sil24, NCQ commands to fan out port 1 and
2 (0 based) often stall if commands are in progress to other ports.
I've tried a number of things but can't tell what's going on.  It
never happens w/ ahci and reportedly sata_mv which can issue NCQ
commands to multiple devices simultaneously like sil24 does.

Disable NCQ for devices behind 4140 PMP for the time being.

Subject: [PATCH 865/869] libata: ignore SIMG4726 config pseudo device

I was hoping ATA_HORKAGE_NODMA | ATA_HORKAGE_SKIP_PM could keep it
happy but no even this doesn't work under certain configurations and
it's not like we can do anything useful with the cofig device anyway.
Replace ATA_HORKAGE_SKIP_PM with ATA_HORKAGE_DISABLE and use it for
the config device.  This makes the device completely ignored by
libata.

Subject: [PATCH 866/869] Fixups to ATA ACPI hotplug

The libata-acpi.c code currently accepts hotplug messages from both the
port and the device. This does not match the behaviour of the bay
driver, and may result in confusion when two hotplug requests are
received for the same device. This patch limits the hotplug notification
to removable ACPI devices, which in turn allows it to use the _STA
method to determine whether the device has been removed or inserted.
On removal, devices are marked as detached. On insertion, a hotplug scan
is started. This should avoid lockups caused by the ata layer attempting
to scan devices which have been removed. The uevent sending is moved
outside the spinlock in order to avoid a warning generated by it firing
when interrupts are disabled.
