#     powerpc/powernv/npu: Remove redundant change_pte() hook
#     
#     The change_pte() notifier was designed to use as a quick path to
#     update secondary MMU PTEs on write permission changes or PFN changes.
#     For KVM, it could reduce the vm-exits when vcpu faults on the pages
#     that was touched up by KSM. It's not used to do cache invalidations,
#     for example, if we see the notifier will be called before the real PTE
#     update after all (please see set_pte_at_notify that set_pte_at was
#     called later).
#     
#     All the necessary cache invalidation should all be done in
#     invalidate_range() already.
