Pull x86 cpu updates from Peter Anvin:
 "This is a corrected attempt at the x86/cpu branch, this time with the
  fixes in that makes it not break on KVM (current or past), or any
  other virtualizer which traps on this configuration.

  Again, the biggest change here is enabling the WC+ memory type on AMD
  processors, if the BIOS doesn't."
