Subject: [PATCH 00/16] last-minute patches for MCE .31

Here are 16 patches for bugfixes and cleanups etc.
These are against tip/x86/mce3, but today I confirmed that these
can be applied on Linus's latest, with no errors.

Please consider applying these for .31

[1] Bugfix
      x86, mce: don't init timer if !mce_available
      x86, mce: call-in should be after updating global_nwo

 These bugs are not serious, but should be fixed asap.

[2] Misc (requested by Ingo)
      x86, mce: add __read_mostly
      x86, mce: rename static variables around trigger
      x86, mce: sysfs entries for new options

 Minor improvements (cleanups), and an enhancement for a feature
 newly introduced in this merge window (i.e. run-time disablement
 of cmci).

[3] Cleanups
      x86, mce: unify mce.h
      x86, mce: make mce_disabled boolean
      x86, mce: unify smp_thermal_interrupt, prepare p4
      x86, mce: unify smp_thermal_interrupt, prepare mce_intel_64
      x86, mce: unify smp_thermal_interrupt, prepare
      x86, mce: unify smp_thermal_interrupt
      x86, mce: squash mce_intel.c into therm_throt.c
      x86, mce: remove intel_set_thermal_handler()
      x86, mce: remove therm_throt.h
      x86, mce: mce.h cleanup
      x86, mce: rename

 There are 3 goals:

 [3-1] unify mce.h
   There are 2 files named mce.h:
        arch/x86/include/asm/mce.h
        arch/x86/kernel/cpu/mcheck/mce.h
   The latter is small, and in it:
        #include <asm/mce.h>
   so we can have a unified one.

 [3-2] finish unifying thermal codes
   Now codes for thermal interrupt is distributed for multiple
   files.  We can gather them in one therm_throt.c file.

 delete mode 100644 arch/x86/include/asm/therm_throt.h
 delete mode 100644 arch/x86/kernel/cpu/mcheck/mce_intel.c

   This makes Makefile clean & simple:
   before:
     obj-y                            =  mce.o therm_throt.o
     obj-$(CONFIG_X86_MCE_P4THERMAL)  += mce_intel.o
     obj-$(CONFIG_X86_MCE_INTEL)      += mce_intel_64.o mce_intel.o
   after:
     obj-y                            =  mce.o
     obj-$(CONFIG_X86_MCE_INTEL)      += mce_intel_64.o
     obj-$(CONFIG_X86_THERMAL_VECTOR) += therm_throt.o

 [3-3] rename
   Rename files that are no longer 64bit specific:
        mce_amd_64.c    => mce_amd.c
        mce_intel_64.c  => mce_intel.c

Thanks,
H.Seto
