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.

Pulled into the arm64 for-next/fixes branch. I'll send a pull request to Linus later today.

BTW, I'm also away next week. I'll randomly check emails but if you have another pull request, better send it to Will.

Thanks.

Looks like this pull request was never sent (the last arm64 fixes PR is from August 16), so I pulled this now.

Duplicate commits are generally harmless so it shouldn't be an issue if they end up being sent by Catalin as well.

Thanks,

Paolo

I think this was all pulled by Linus over a week ago:
