Merge branch 'x86-ras-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 RAS changes from Ingo Molnar:

 - SCI reporting for other error types not only correctable ones

 - GHES cleanups

 - Add the functionality to override error reporting agents as some
   machines are sporting a new extended error logging capability which,
   if done properly in the BIOS, makes a corresponding EDAC module
   redundant

 - PCIe AER tracepoint severity levels fix

 - Error path correction for the mce device init

 - MCE timer fix

 - Add more flexibility to the error injection (EINJ) debugfs interface

  ACPI, APEI, GHES: Do not report only correctable errors with SCI
  ACPI, APEI, EINJ: Changes to the ACPI/APEI/EINJ debugfs interface
  ACPI, eMCA: Combine eMCA/EDAC event reporting priority
  EDAC, sb_edac: Modify H/W event reporting policy
  EDAC: Add an edac_report parameter to EDAC
  PCI, AER: Fix severity usage in aer trace event
  x86, mce: Call put_device on device_register failure
