Subject: drm/amdkfd: fix build, select MMU_NOTIFIER
Git-commit: 7bbc0b950f34bf11c26a32b6beb927777e7f3b93
Patch-mainline: v4.17-rc3
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
When CONFIG_MMU_NOTIFIER is not enabled, struct mmu_notifier has an
incomplete type definition, which causes build errors.
