Merge branch 'kvm-5.20-msr-eperm'

Merge a bug fix and cleanups for {g,s}et_msr_mce() using a base that
predates commit 281b52780b57 ("KVM: x86: Add emulation for
MSR_IA32_MCx_CTL2 MSRs."), which was written with the intention that it
be applied _after_ the bug fix and cleanups.  The bug fix in particular
needs to be sent to stable trees; give them a stable hash to use.
