Merge branch 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull RAS updates from Ingo Molnar:
 "The main changes in this cycle were:

  - Assign notifier chain priorities for all RAS related handlers to
    make the ordering explicit (Borislav Petkov)

  - Improve the AMD MCA banks sysfs output (Yazen Ghannam)

  - Various cleanups and restructuring of the x86 RAS code (Borislav
    Petkov)"

* 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/ras, EDAC, acpi: Assign MCE notifier handlers a priority
  x86/ras: Get rid of mce_process_work()
  EDAC/mce/amd: Dump TSC value
  EDAC/mce/amd: Unexport amd_decode_mce()
  x86/ras/amd/inj: Change dependency
  x86/ras: Flip the TSC-adding logic
  x86/ras/amd: Make sysfs names of banks more user-friendly
  x86/ras/therm_throt: Do not log a fake MCE for thermal events
  x86/ras/inject: Make it depend on X86_LOCAL_APIC=y
