ppc patch queue for 2021-04-21 Here's what I hope is the last ppc related pull request for qemu-6.0. The 2 patches here revert a behavioural change that after further discussion we concluded was a bad idea (adding a timeout for possibly-failed hot unplug requests). Instead it implements a different approach to the original problem: we again let unplug requests the guest doesn't respond to remain pending indefinitely, but no longer allow those to block attempts to retry the same unplug again. The change is a bit more complex than I'd like for this late in the freeze. Nonetheless, I think it's important to merge this for 6.0, so we don't allow a release which has the probably-a-bad-idea timeout behaviour.
