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

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.

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