Pull x86 fix from Thomas Gleixner:
 "A single fix for x86.

  Revert the recent change to the MTRR code which aimed to support
  SEV-SNP guests on Hyper-V. It caused a regression on XEN Dom0 kernels.

  The underlying issue of MTTR (mis)handling in the x86 code needs some
  deeper investigation and is definitely not 6.2 material"
