Alistair Popple ec8832d007 mmu_notifiers: don't invalidate secondary TLBs as part of mmu_notifier_invalidate_range_end()
Secondary TLBs are now invalidated from the architecture specific TLB
invalidation functions.  Therefore there is no need to explicitly notify
or invalidate as part of the range end functions.  This means we can
remove mmu_notifier_invalidate_range_end_only() and some of the
ptep_*_notify() functions.
