Hmm. My laptop (XPS 13) doesn't resume any more. It suspends, but
doesn't come back from resume.

I immediately assumed it was the power management pulls I just did,
but then I started bisecting, and now it's actually pointing into the
various x86 pulls I did yesterday instead.

Now, I'm reasonably early in my bisection (so literally "somewhere
between the 'docs-next' and the 'x86-mm-for-linus' pull), and maybe
the problem isn't even entirely repeatable and my bisection has
already gone off the rails, but I thought I'd give at least an early
heads-up about this thing.

I'll have more as it bisects deeper into the merge window, but it
might be a while.
