Linus Torvalds 925cf0457d A single fix for x86:
Revert the recent change to the MTRR code which aimed to support
   SEV-SNP guests on Hyper-V. It cuased 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.
