Ok, tip guys, so Jörg and I talked about the IOPFs a bit and we feel
that while they still need to be taken care of, they're harmless and
there's no need to hold off tip/x86/apic anymore unless there are other
problems with it.

So, from my POV, it can go in so that it doesn't miss this merge window
and we'd deal with the IOPFs later.

I'm guessing Jiang needs to give you some updated versions of patches
from this thread for the branch to be complete. Jiang, please add my

Tested-by: Borislav Petkov <bp@...e.de>

for those.

Thanks to everyone involved.
