I have "queued" it, but that's just my queue - it's not on kernel.org 
and it's not going to be in 5.16, at least not in the first batch.

There's plenty of time for me to rebase on top of a fix, if you want to 
send the fix through your kvm-arm pull request.  Just Cc me so that I 
understand what's going on.

Thanks,
