| |
Fix bugs in set_msr_mce() where KVM returns '-1' instead of '1' when rejecting a WRMSR, which results in -EPERM getting returned to userspace.
Patches 2 and 3 are cleanups to make {g,s}et_msr_mce a bit less wierd (especially with respect to Jue's CMCI series) and a bit less magical.
Sean Christopherson (3): KVM: x86: Signal #GP, not -EPERM, on bad WRMSR(MCi_CTL/STATUS) KVM: x86: Use explicit case-statements for MCx banks in {g,s}et_msr_mce() KVM: x86: Add helpers to identify CTL and STATUS MCi MSRs
