Subject[PATCH 0/5] KVM: x86: Fix KVM behavior that does not follow spec
Date
This series of patches fix various scenarios in which KVM behavior does not
follow x86 specifications. Each patch actually deals with a separate bug.
These bugs can cause the guest to get stuck (i.e., make no progress), encounter
spurious injected exceptions, or cause guest code to misbehave. As a result
guest OS can potentially fail.

Thanks for reviewing the patches.

Nadav Amit (5):
KVM: x86: Fix wrong/stuck PMU when guest does not use PMI
KVM: x86: Fix CR3 reserved bits
KVM: x86: IN instruction emulation should ignore REP-prefix
KVM: x86: RSI/RDI/RCX are zero-extended when affected by string ops
KVM: x86: Processor mode may be determined incorrectly
