It's unclear whether this patch is in addition to Arnd's "mm: HMM always
needs MMU_NOTIFIER" or is a replacement for it.  (If the latter, it
should have Arnd's Reported-by).  But I cannot get this patch to apply
cleanly in either situation.

So I'll skip both patches.  Please send something which applies on top
of
