[GIT PULL] KVM/arm64 fixes for 6.11, round #2

[GIT PULL] KVM/arm64 fixes for 6.11, round #2

[Oliver Upton]

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

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:

Yeah, that's what happens if you "git rebase v6.11-rc6" on the wrong machine.
