[PATCH v2 0/2] Fix MSR access errors during kexec in root partition

[Anirudh Rayabharam]

Fixes a couple of MSR access errors seen during kexec in root partition
and opportunistically introduces a data structure for the reference TSC
MSR in order to simplify the code that updates that MSR.

New in v2:
1. Reverse the patch order as suggested by Michael. First introduce the
   new structure for reference tsc MSR and then use it in the hv_cleanup
   fix.
2. Use hv_{get,set}_register functions in hv_cleanup().

Anirudh Rayabharam (2):
  clocksource/drivers/hyperv: add data structure for reference TSC MSR
  x86/hyperv: fix invalid writes to MSRs during root partition kexec
