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

Pull x86 fixes from Peter Anvin:
 "One (hopefully) last batch of x86 fixes.  You asked for the patch by
  patch justifications, so here they are:

      x86, MCE: Retract most UAPI exports

   This one unexports from userspace a bunch of definitions which should
   never have been exported.  We really don't want to create an
   accidental legacy here.

      x86, doc: Add a bootloader ID for OVMF

   This is a documentation-only patch, just recording the official
   assignment of a boot loader ID.

      x86: Do not leak kernel page mapping locations

   Security: avoid making it needlessly easy for user space to probe the
   kernel memory layout.

      x86/mm: Check if PUD is large when validating a kernel address

   Prevent failures using /proc/kcore when using 1G pages.

      x86/apic: Work around boot failure on HP ProLiant DL980 G7 Server systems

   Works around a BIOS problem causing boot failures on affected hardware."
