Hi Catalin,

Paolo is on holiday for a few weeks and has asked that KVM arch maintainers
send pulls through the architecture trees in his absence.

So lucky you, here's a pile of kvmarm crap from the past week.

Details can be found in the tag, but this is a set of small fixes
around the shop thanks to syzkaller bringup on KVM/arm64 and a few
recently introduced bugs.

Please pull.

Thanks,
Oliver
