SubjectRe: Splat during resume
I think this is the same as the kexec issue that also hit -tip.

It's *probably* fixed by the final series to actually enable 5-level
paging (which I don't think is in -tip yet), but even if that is the
case this is obviously a nasty bisectability problem.

You migth want to verify, though. The second batch starts here:

Hmm?

In the meantime, this is currently -tip only, so I will stack back
from this thread unless you can reproduce it in mainline too.
