148b508309 x86: NMI watchdog: Downgrade helper
A downgrade helper for the NMI watchdog to be used in all places where
the I/O APIC watchdog may have been requested, but the I/O APIC is found
not to be there or meant to be left disabled.  This is so that the
reconfiguration is cosistent and defined in a single place only.

35542c5ebc x86: I/O APIC: clean up the 8259A on a NMI watchdog failure
There is no point in keeping the 8259A enabled if the I/O APIC NMI
watchdog has failed and the 8259A is not used to pass through regular
timer interrupts.  This fixes problems with some systems where some logic
gets confused.

ecd29476ae x86: I/O APIC: remove parameters to fiddle with the 8259A
Remove the "disable_8254_timer" and "enable_8254_timer" kernel
parameters.  Now that AEOI acknowledgements are no longer needed for
correct timer operation, the 8259A can be kept disabled unconditionally
unless interrupts, either timer or watchdog ones, are actually passed
through it.

ca3739327b x86: KVM guest: Add memory clobber to hypercalls
Hypercalls can modify arbitrary regions of memory.  Make sure to indicate this

GCC 4.3.0.

This was originally spotted and analyzed by Marcelo.

ca31e146d5 Move _RET_IP_ and _THIS_IP_ to include/linux/kernel.h
These two macros are useful beyond lock debugging. Moved definitions from
include/linux/debug_locks.h to include/linux/kernel.h, so code that needs
them does not have to include the former, which would have been a less
intuitive choice of a header.

acb7669c12 cpumask: introduce new APIs
In linux-next there is a commit ("x86: Add performance variants of cpumask
operators") which, as part of the 4096 cpu support work adds some new APIs
for dealing with cpu masks.  Add trivial versions of these now so that
subsystems can update in a timely manner and avoid conflicts in linux-next
and the next merge window.

e08c1694d9 olpc: sdhci: add quirk for the Marvell CaFe's vdd/powerup issue
This has been sitting around unloved for way too long..

The Marvell CaFe chip's SD implementation chokes during card insertion
if one attempts to set the voltage and power up in the same
SDHCI_POWER_CONTROL register write.  This adds a quirk that does
that particular dance in two steps.

It also adds an entry to pci_ids.h for the CaFe chip's SD device.

086f7316f0 security: filesystem capabilities: fix fragile setuid fixup code
This commit includes a bugfix for the fragile setuid fixup code in the
case that filesystem capabilities are supported (in access()).  The effect
of this fix is gated on filesystem capability support because changing
securebits is only supported when filesystem capabilities support is
configured.)

list.h to rculist.h.  Add a trivial version of the file now so that
various subsystem trees can start using it now for -next changes and so
reduce the build errors caused by adding uses of the moved functions.

There's a slight fault in the stub logic.  It fails for FW_LOADER=m and
the user =y.

This should fix it.

5095202603 [MIPS] Fix bug in atomic_sub_if_positive.
The branch optimization fixes in 2.6.21 introduced a bug in
atomic_sub_if_positive that causes it to return even when the sc
instruction fails. The result is that e.g. down_trylock becomes unreliable
as the semaphore counter is not always decremented.

41d54d3bf8 slub: Do not use 192 byte sized cache if minimum alignment is 128 byte
The 192 byte cache is not necessary if we have a basic alignment of 128
byte. If it would be used then the 192 would be aligned to the next 128 byte
boundary which would result in another 256 byte cache. Two 256 kmalloc caches
cause sysfs to complain about a duplicate entry.

MIPS needs 128 byte aligned kmalloc caches and spits out warnings on boot without
this patch.

18ce3751cc Properly notify block layer of sync writes
fsync_buffers_list() and sync_dirty_buffer() both issue async writes and
then immediately wait on them. Conceptually, that makes them sync writes
and we should treat them as such so that the IO schedulers can handle
them appropriately.

This patch fixes a write starvation issue that Lin Ming reported, where
xx is stuck for more than 2 minutes because of a large number of
synchronous IO in the system:

"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this

251a4b320f net/inet_lro: remove setting skb->ip_summed when not LRO-able
When an SKB cannot be chained to a session, the current code attempts
to "restore" its ip_summed field from lro_mgr->ip_summed. However,
lro_mgr->ip_summed does not hold the original value; in fact, we'd
better not touch skb->ip_summed since it is not modified by the code
in the path leading to a failure to chain it.  Also use a cleaer
comment to the describe the ip_summed field of struct net_lro_mgr.

b660398101 kbuild: fix a.out.h export to userspace with O= build.
We need to check for existence of the a.out.h header in the source tree,
not the object tree, if we want it to get the right answer with O=.

7fa8e6fa15 V4L/DVB (8092): videodev: simplify and fix standard enumeration
VIDIOC_ENUMSTD did not return all the PAL/SECAM/NTSC variants: it just returned
one single PAL/SECAM/NTSC standard without separate entries for the trickier
standards like NTSC-JP.

Changed the code so that it behaves better.

Also simplified the if/switch statements into a common standards lookup table.

16d7523973 thermal: Create CONFIG_THERMAL_HWMON=n
A bug in libsensors <= 2.10.6 is exposed
when this new hwmon I/F is enabled.
Create CONFIG_THERMAL_HWMON=n
until some time after libsensors 2.10.7 ships
so those users can run the latest kernel.

libsensors 3.x is already fixed -- those users
can use CONFIG_THERMAL_HWMON=y now.

This patch adds structs for the paravirt clocksource ABI
used by both xen and kvm (pvclock-abi.h).

It also adds some helper functions to read system time and
wall clock time from a paravirtual clocksource (pvclock.[ch]).
They are based on the xen code.  They are enabled using
CONFIG_PARAVIRT_CLOCK.

Subsequent patches of this series will put the code in use.

2849914393 xen: remove support for non-PAE 32-bit
Non-PAE operation has been deprecated in Xen for a while, and is
rarely tested or used.  xen-unstable has now officially dropped
non-PAE support.  Since Xen/pvops' non-PAE support has also been
broken for a while, we may as well completely drop it altogether.

06e0564566 KVM: close timer injection race window in __vcpu_run
If a timer fires after kvm_inject_pending_timer_irqs() but before
local_irq_disable() the code will enter guest mode and only inject such
timer interrupt the next time an unrelated event causes an exit.

It would be simpler if the timer->pending irq conversion could be done
with IRQ's disabled, so that the above problem cannot happen.

For now introduce a new vcpu requests bit to cancel guest entry.
