Hi Andrew, Chris,
Andrew: This is a fixup that applies to today's (20200521) linux-next.
In that tree, this fixes up:
commit dfb8dfe80808 ("mm/gup: refactor and de-duplicate gup_fast() code")
Chris: I'd like to request another CI run for the drm/i915 changes, so
for that, would you prefer that I post a v2 of the series [1], or
is it easier for you to just apply this patch here, on top of [2]?
[1] https://lore.kernel.org/r/20200519002124.2025955-1-jhubbard@nvidia.com
[2] https://lore.kernel.org/r/158985123351.31239.10766458886430429630@emeril.freedesktop.org
thanks,
John Hubbard

If you post your series again with this patch included to intel-gfx, CI
will pick it up. Or I'll do that in the morning.

OK, perfect. I'll post a version for linux.git in a moment here.
