2011-04-13ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio()Eric Miao
This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup event. It is misinterpreted as a gpio irq not a PWER bitmask. Fixed this by converting the incorrect IRQ_TO_IRQ() to a correct version of irq_to_gpio(). Reported-by: Nick Bane <nickbane1@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

Restore the initialization of mmu_cr4_features during boot, which was removed without comment in checkin e5f15b45ddf3afa2bbbb10c7ea34fb32b6de0a0e 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.)

2011-04-06KVM: move and fix substitue search for missing CPUID entriesAndre Przywara
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.

2011-04-06KVM: fix XSAVE bit scanningAndre Przywara
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.

Commit b3df895aebe091b1657 "powerpc/kexec: Add support for FSL-BookE" introduced the original PPC_STD_MMU_64 checks around the function crash_kexec_wait_realmode(). Then commit c2be05481f61252 "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.

2011-04-01rcu: create new rcu_access_index() and use in mcePaul E. McKenney
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.
