Consequently, there are fixes sitting in limbo and we /still/ don't have a sensible base for arm64/kvm patches targetting 5.8. Paolo -- how can I help get this stuff moving again? I'm more than happy to send this lot up to Linus via arm64 if you're busy atm. Please just let me know. Cheers, Will

So this is basically really bad timing in Marc's first pull request, that he couldn't have anticipated. I have pulled both trees now, so you can base 5.8 development on kvm/master. It will get to Linus in a couple days. Paolo

If possible, please just let us know in future as we can probably figure something out rather than having things sit in limbo. > I have pulled both trees now, so you can base 5.8 development on > kvm/master.

I got stuck in a "1: tomorrow should be better" / "no it was actually worse" / "goto 1b" loop. Paolo
Paolo, This is the second batch of KVM/arm fixes for 5.7. A compilation fix, a GICv4.1 fix, plus a couple of sanity checks (SP_EL0 save/restore, and the sanitising of AArch32 registers). Note that the pull request I sent a week ago[1] is still valid, and that this new series is built on top of the previous one. Please pull, M.
