It also replaces
[PATCH 19 of 24] cacheline align VM_is_OOM to prevent false sharing
since locking isn't globally done with VM_is_OOM anymore.
Also, the patch
[PATCH 17 of 24] apply the anti deadlock features only to global oom
will no longer need to move the global locking mechanism since its now
non-existant, but the deadlock feature is still apporpriate in the
CONSTRAINT_NONE (i.e. global) case.
