Subject: drm/amdgpu: update to new mmu_notifier semantic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: c90270a9f11b455102874c15c4c9c1dabb0d030b
Patch-mainline: v4.13
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Calls to mmu_notifier_invalidate_page() were replaced by calls to
mmu_notifier_invalidate_range() and are now bracketed by calls to
mmu_notifier_invalidate_range_start()/end()
Remove now useless invalidate_page callback.
