0b699e36b2 [PATCH] x86_64: bring back __read_mostly support to linux-2.6.17-rc2
It seems latest kernel has a wrong/missing __read_mostly implementation
for x86_64

__read_mostly macro should be declared outside of #if CONFIG_X86_VSMP block

18bd057b14 [PATCH] i386/x86-64: Fix x87 information leak between processes
AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE
when an exception is pending.  This means the value leak through
context switches and allow processes to observe some x87 instruction
state of other processes.

This was actually documented by AMD, but nobody recognized it as
being different from Intel before.

The fix first adds an optimization: instead of unconditionally
calling FNCLEX after each FXSAVE test if ES is pending and skip
it when not needed. Then do a x87 load from a kernel variable to
clear FOP/FIP/FDP.

This means other processes always will only see a constant value
defined by the kernel in their FP state.

I took some pain to make sure to chose a variable that's already
in L1 during context switch to make the overhead of this low.

Also alternative() is used to patch away the new code on CPUs
who don't need it.

Patch for both i386/x86-64.

The problem was discovered originally by Jan Beulich. Richard
Brunner provided the basic code for the workarounds, with contribution
from Jan.

This is CVE-2006-1056

aafda4e0d0 [PATCH] update OBSOLETE_OSS_DRIVER schedule and dependencies
Update the schedule for the removal of drivers depending on
OBSOLETE_OSS_DRIVER as follows:

- adjust OBSOLETE_OSS_DRIVER dependencie
- from the release of 2.6.16 till the release of 2.6.17:
  approx. two months for users to report problems with the ALSA
  drivers for the same hardware
- after the release of 2.6.17 (and before 2.6.18):
  remove the subset of drivers marked at OBSOLETE_OSS_DRIVER without
  known regressions in the ALSA drivers for the same hardware

Additionally, correct some OBSOLETE_OSS_DRIVER dependencies.

962f831f67 [PATCH] sound: fix hang in mpu401_uart.c
This fixes a hang in mpu401_uart.c that can occur when the mpu401 interface
is non-existent or otherwise doesn't respond to commands but we issue IO
anyway.  snd_mpu401_uart_cmd now returns an error code that is passed up
the stack so that an open() will fail immediately in such cases.

Eventually discovered after wine/cxoffice would constantly cause hard
lockups on my desktop immediately after loading (emulating Windows too
well).  Turned out that I'd recently moved my sound cards around and using
/dev/sequencer now talks to a sound card with a broken MPU.

This second version changes -EFAULT to -EIO and frees open resources on
error too.  Test booted and seems to work ok.

c79cfbacca [PATCH] i2c-i801: Fix resume when PEC is used
Fix for bug #6395:

Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM

The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume
after the i2c-i801 driver has left the SMBus in PEC mode.  The most simple
fix is to clear the PEC bit after after every transaction.  That's what
this driver was doing up to 2.6.15 (inclusive).

Thanks to Daniele Gaffuri for the very good report.

7daa0c4f51 [PATCH] MSI-K8T-Neo2-Fir OnboardSound and additional Soundcard
On the MSI-K8T-NEO2 FIR ( Athlon-64, Socket 939 with VIA-K8T800- Chipset
and onboard Sound,...  ) the BIOS lets you choose "DISABLED" or "AUTO" for
the On-Board Sound Device.

If you add another PCI-Sound-Card the BIOS disables the on-board device.

So far I have a Quirk, that does set the correspondent BIT in the
PCI-registers to enable the soundcard.

But how to ensure that the code is executed ONLY on excactly this kind of
boards (not any other with similar Chipset)?

Add some sanity checking.  truesize should be at least sizeof(struct

But we can add checks to more spots over time.

9b0b4d8ae8 [PATCH] softmac: fix spinlock recursion on reassoc
This fixes a spinlock recursion on receiving a reassoc request.

On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.

Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.

This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

c1783454a3 [PATCH] Revert NET_RADIO Kconfig title change
2.6.17-rc1 changed the title for the entry CONFIG_NET_RADIO. I
personally disagree with this change and want it reverted. Patch for
2.6.17-rc1.
	Rationale : WIRELESS_EXT is an invisible option. Therefore,
the only way for a user to enable it is via NET_RADIO. Some users need
to do that for out-of-tree drivers. Therefore it should be mentionned
in the title of the option.
	Rationale2 : the option just below is called "Wireless
Extension API over RtNetlink". Some users may confuse this option for
the main "Wireless Extension" option. Therefore reverting this change
help disambiguate the relation between those two options.

a417016d1a [PATCH] wext: Fix IWENCODEEXT security permissions
Check the permissions when user-space try to read the
encryption parameters via SIOCGIWENCODEEXT. This is trivial and
probably should go in 2.6.17...

6fcdf565ff [PATCH] wireless/airo: clean up WEXT association and scan events
Airo firmware versions >= 5.30.17 send re-association events to the
driver that are currently unrecognized, causing spurious disassociation
events to be sent to user space.  Loss of sync due to scan requests also
results in disassociation events sent to user space.  This patch traps
those two events; suppressing sync-loss on scan, and sending the correct
association event on re-association notifications.
