Pull x86 mtrr updates from Borislav Petkov:
 "A serious scrubbing of the MTRR code including adding a new map
  mechanism in order to look up the memory type of a region easily.

  Also address memory range lookup issues like returning an invalid
  memory type. Furthermore, this handles the decoupling of PAT from MTRR
  more naturally.

  All work by Juergen Gross"
