Merge branch 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull miscellaneous x86 fixes from Peter Anvin:
 "The biggest ones are fixing suspend/resume breakage on 32 bits, and an
  interrim fix for mapping over holes that allows AMD kit with more than
  1 TB.

  A final solution for the latter is in the works, but involves some
  fairly invasive changes that will probably mean it will only be
  appropriate for 3.8."

* 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, MCE: Remove bios_cmci_threshold sysfs attribute
  x86, amd, mce: Avoid NULL pointer reference on CPU northbridge lookup
  x86: Exclude E820_RESERVED regions and memory holes above 4 GB from direct mapping.
  x86/cache_info: Use ARRAY_SIZE() in amd_l3_attrs()
  x86/reboot: Remove quirk entry for SBC FITPC
  x86, suspend: Correct the restore of CR4, EFER; skip computing EFLAGS.ID
