To give zero regression risk to 1/12 when MMU_NOTIFIER=y or =n and the
mmu notifiers aren't registered by GRU or KVM. Keep in mind that the
whole point of my proposed patch ordering from day 0, is to keep as
1/N, the absolutely minimum change that fully satisfy GRU and KVM
requirements. 4/12 isn't required by GRU/KVM so I keep it in a later
patch. I now moved mmu_notifier_unregister in a later patch too for
the same reason.
