I applied this to 60675d4ca1ef0 ("Merge branch 'linus' into x86/mm, to pick up
fixes"), booted it and ran some selftests on a Milan and a Genoa machine, no
issues, although I didn't have CONFIG_DEBUG_VM or anything like that. I did see
the warning reported by Oleksandr [0] on QEMU.
I tried to test Turin but there's some unrelated brokenness. Due to other
unrelated issues I also couldn't test with lockdep.
Anyway I guess that counts as:

I couldn't get any performance data either, more unrelated brokenness. Maybe I
can try again next week.
I posted some bikeshed review comments but I haven't grokked the interesting
bits yet, will try to do that next week too.
