The fix patch was already posted, but in another thread (confusingly
with _almost_ the same subject: "Re: Linux 4.15-rc2: Regression in
resume from ACPI S3").

Here:

  https://git.kernel.org/pub/scm/linux/kernel/git/luto/linux.git/commit/?h=x86/fixes

but it hasn't actually gotten to me yet (I think Luto made a new
version where he split it up into three smaller patches, and I'm
assuming it's in one of the -tip trees heading for me asap).

All the x86 people have been insanely busy with the crazy page table
isolation patches, that probably is slowing down things. But I was
expecting to get the -tip tree pulls tomorrow (.. because.. Friday.
It's my busiest day of the week because everybody wants to get their
work out before the weekend).
