Hey Andrew,

These are a few requested cleanups for the "mm: userspace hugepage collapse, v7"
series[1] currently in mm-unstable.  Please considering squashing them into the
v7 series.  Note that https://lkml.kernel.org/r/Ys4aTRqWIbjNs1mI@google.com is
still outstanding, and that the series is incomplete until a suitable resolution
is reached there.

Thanks, and apologies for the multiple fixes / adjustments required here.
Zach
