[GIT PULL] x86/mm for 7.2-rc1

[Dave Hansen]

Hi Linus,

Please pull some x86/mm changes for 7.2-rc1. There's a small comment
fixup, followed by an actual bug fix. The bug fix is slightly new
territory for us.  It fixes a real regression, but it is from ~6.18
not a _new_ regression. It was mostly only biting folks doing hotplug
memory testing. So, it was queued in here and held for the merge
window instead of going via x86/urgent.

We _think_ holding on to things like this is what you asked for in
the 7.1-rc5 announcement. Please holler if this isn't what you were
hoping for.

This sounds about right to me. If the fix doesn't affect any normal
users, there's no huge reason to try to expedite it.

It's always a judgement call, obviously. So it's not like there's "one
correct thing".

I just do want people to *make* that judgement, not just some mindless
"it's a fix" without any judgement on importance or possible risks...
