47912a657e ARM: Tegra: select MACH_HAS_SND_SOC_TEGRA_WM8903
CONFIG_SND_SOC_TEGRA_WM8903 is useful for many Tegra boards. To avoid the
ASoC tegra/Kconfig enumerating them all, instead have the Tegra machine
Kconfig select MACH_HAS_SND_SOC_TEGRA_WM8903 where appropriate, and have
SND_SOC_TEGRA_WM8903 depend on this.

[Redid ASoC diff so it applies. -- broonie]

61a6d0764b ARM: Tegra: Add to tegra_wm8903_platform_data
Seaboard derivate Kaen has a GPIO to mute the headphone output. Add a field
to tegra_wm8903_platform_data so the board files can pass the GPIO number
for that to the ASoC machine driver.

Also, initialize this new field to a "not present" value for Harmony.

4da9484bde x86, hibernate: Initialize mmu_cr4_features during boot
Restore the initialization of mmu_cr4_features during boot, which was
removed without comment in checkin e5f15b45dd

x86: Cleanup highmap after brk is concluded

thereby breaking resume from hibernate.  This restores previous
functionality in approximately the same place, and corrects the
reading of %cr4 on pre-CPUID hardware (%cr4 exists if and only if
CPUID is supported.)

However, part of the problem is that the hibernate suspend/resume
sequence should manage the save/restore of %cr4 explicitly.

bd22f5cfcf KVM: move and fix substitue search for missing CPUID entries
If KVM cannot find an exact match for a requested CPUID leaf, the
code will try to find the closest match instead of simply confessing
it's failure.
The implementation was meant to satisfy the CPUID specification, but
did not properly check for extended and standard leaves and also
didn't account for the index subleaf.
Beside that this rule only applies to CPUID intercepts, which is not
the only user of the kvm_find_cpuid_entry() function.

So fix this algorithm and call it from kvm_emulate_cpuid().
This fixes a crash of newer Linux kernels as KVM guests on
AMD Bulldozer CPUs, where bogus values were returned in response to
a CPUID intercept.

20800bc940 KVM: fix XSAVE bit scanning
When KVM scans the 0xD CPUID leaf for propagating the XSAVE save area
leaves, it assumes that the leaves are contigious and stops at the
first zero one. On AMD hardware there is a gap, though, as LWP uses
leaf 62 to announce it's state save area.
So lets iterate through all 64 possible leaves and simply skip zero
ones to also cover later features.

b987812b3f powerpc/kexec: Fix mismatched ifdefs for PPC64/SMP.
Commit b3df895aeb "powerpc/kexec: Add support for FSL-BookE"
introduced the original PPC_STD_MMU_64 checks around the function
crash_kexec_wait_realmode().   Then commit c2be05481f
"powerpc: Fix default_machine_crash_shutdown #ifdef botch" changed
the ifdef around the calling site to add a check on SMP, but the
ifdef around the function itself was left unchanged, leaving an
unused function for PPC_STD_MMU_64=y and SMP=n

Rather than have two ifdefs that can get out of sync like this,
simply put the corrected conditional around the function and use
a stub to get rid of one set of ifdefs completely.

034e9e966c [S390] Fix parameter passing for smp_switch_to_cpu()
After the execution has been switched to the destination CPU, the target
function is called with the wrong parameter. According to the C calling
convention on s390, the first parameter should be loaded into register 2.
Currently in smp_restart_cpu() it is stored in register 3. To fix this, we
load the parameter into the correct register 2.

Prevent stack corruption by memcpy which copies more bytes then
available at the destination. While at it use the new test_facility
to test for the facility bit.

In commit f5e5bf088b
  ia64: Use irqd_irq_disabled() instead of desc->status access

Thomas forgot to convert from irq to *irq_data.

Add a call to irq_get_irq_data() to fix that.

a4dd99250d rcu: create new rcu_access_index() and use in mce
The MCE subsystem needs to sample an RCU-protected index outside of
any protection for that index.  If this was a pointer, we would use
rcu_access_pointer(), but there is no corresponding rcu_access_index().
This commit therefore creates an rcu_access_index() and applies it
to MCE.
