Subject: [PATCH v2 0/2] Fix MSR access errors during kexec in root partition
Date: Thu, 27 Oct 2022 15:27:27 +0530 [thread overview]
Message-ID: <20221027095729.1676394-1-anrayabh@linux.microsoft.com> (raw)
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().

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