Subject: [PATCH 0/3] KVM: VMX: fix handling inv{ept,vpid} and nested RHEL6 KVM

Patches 1 and 2 fix two cases where a guest could hang at 100% CPU
due to mis-emulation of a failing invept or invvpid.

Patch 3 works around a bug in RHEL6 KVM, which is exposed by nested
VPID support; RHEL6 KVM uses single-context invvpid unconditionally,
but until now KVM did not provide it.
