KVM: x86: Second batch of updates for 6.1, i.e. kvm/queue

[Sean Christopherson <seanjc@google.com>]

Second and likely final batch of x86 updates for 6.1, i.e. for kvm/queue.  All
larger series (NX precision, Hyper-V TLB flush, AVIC fixes, etc...) are
destined for 6.2.

There are a variety of selftest fixes and improvements that I think we should
get into 6.1, but they're not x86 specific, i.e. I need to sync with you to
figure out how to handle those.

Note, Like's PEBS KVM-unit-tests[1] will fail unless the PMU fix that's going
through the tip tree is also applied[2].  That's my fault, I requested Like to
post it separately without thinking through the KUT ramifications.

Thanks!
