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!
