[Xen-devel] [PATCH v2 0/2] add support for vNVDIMM - Part 1: enable instructions

[Haozhong Zhang <haozhong.zhang@xxxxxxxxx>]

I split the previous patch series "[PATCH 0/4] add support for vNVDIMM"
into two parts. This is the first part that enables clflushopt/clwb/pcommit
instructions for HVM guests.

[The second part will be sent separately after v1 patches get reviewed.]

Changes in v2:
 * Refactor modifications in hvm_cpuid() per Andrew Cooper's comments.

Haozhong Zhang (2):
  x86/hvm: allow guest to use clflushopt and clwb
  x86/hvm: add support for pcommit instruction
