[PATCH 0/3] mmu_notifiers follow ups

[Michal Hocko]

Hi Andrew,
Tetsuo has noticed some fallouts from 93065ac753e4 ("mm, oom:
distinguish blockable mode for mmu notifiers"). One of them has
been fixed and picked up by AMD/DRM maintainer [1]. XEN issue is
fixed by patch 1. I have also clarified expectations about blockable
semantic of invalidate_range_end. Finally the last patch removes
MMU_INVALIDATE_DOES_NOT_BLOCK which is no longer used nor needed.
