Subject: Revert "mm, mmu_notifier: annotate mmu notifiers with blockable
invalidate callbacks"
Revert 5ff7091f5a2ca ("mm, mmu_notifier: annotate mmu notifiers with
blockable invalidate callbacks").
MMU_INVALIDATE_DOES_NOT_BLOCK flags was the only one used and it is no
longer needed since 93065ac753e4 ("mm, oom: distinguish blockable mode for
mmu notifiers"). We now have a full support for per range !blocking
behavior so we can drop the stop gap workaround which the per notifier
flag was used for.
