Given the proximity to v6.7 window opening I am going to go ahead and
throw this into linux-next for some soak time. If an x86 maintainer
wants to take it, or otherwise wants me to drop it out linux-next just
holler.
Per above there are limited arch/x86 touches in this series, and it
merges cleanly with tip/master.
I will also copy x86@ on the linux-next branch add request.
