It will be in kvm/next as soon as I finish running tests on it, which 
may take a couple more days because I'm updating my machines to newer 
operating systems.

Ok, thanks for the suggestion.  Generally speaking:

- kvm/master is stuff that is merged and will be in the next -rc, right 
now 5.16-rc4.  It shouldn't ever rewind (though it may happen, it is rare)

- kvm/next is stuff that is merged and will be in the next merge window, 
right now 5.17.  It also shouldn't rewind.

- kvm/queue is stuff that the submitter shouldn't care about, and that 
other people should only care about to check for conflicts.  When I say 
I "queued" a patch it goes in kvm/queue, and there's time to remove it 
if something breaks.

Regarding this series:

- I am queuing it up to this patch

- I am queuing it to kvm/next, meaning it targets 5.17

- it looks like the next one (11/43) triggers a known AMD errata, so I'm 
holding on the rest until we understand if it actually does, and if so 
if AMD AVIC is doomed.  For the time being, it will stay in kvm/queue.
