Merge branch 'drm-next-4.15' of git://people.freedesktop.org/~agd5f/linux into drm-next
First feature pull for 4.15. Highlights: - Per VM BO support - Lots of powerplay cleanups - Powerplay support for CI - pasid mgr for kfd - interrupt infrastructure for recoverable page faults - SR-IOV fixes - initial GPU reset for vega10 - prime mmap support - ttm page table debugging improvements - lots of bug fixes * 'drm-next-4.15' of git://people.freedesktop.org/~agd5f/linux: (232 commits) drm/amdgpu: clarify license in amdgpu_trace_points.c drm/amdgpu: Add gem_prime_mmap support drm/amd/powerplay: delete dead code in smumgr drm/amd/powerplay: delete SMUM_FIELD_MASK drm/amd/powerplay: delete SMUM_WAIT_INDIRECT_FIELD drm/amd/powerplay: delete SMUM_READ_FIELD drm/amd/powerplay: delete SMUM_SET_FIELD drm/amd/powerplay: delete SMUM_READ_VFPF_INDIRECT_FIELD drm/amd/powerplay: delete SMUM_WRITE_VFPF_INDIRECT_FIELD drm/amd/powerplay: delete SMUM_WRITE_FIELD drm/amd/powerplay: delete SMU_WRITE_INDIRECT_FIELD drm/amd/powerplay: move macros to hwmgr.h drm/amd/powerplay: move PHM_WAIT_VFPF_INDIRECT_FIELD to hwmgr.h drm/amd/powerplay: move SMUM_WAIT_VFPF_INDIRECT_FIELD_UNEQUAL to hwmgr.h drm/amd/powerplay: move SMUM_WAIT_INDIRECT_FIELD_UNEQUAL to hwmgr.h drm/amd/powerplay: add new helper functions in hwmgr.h drm/amd/powerplay: use SMU_IND_INDEX/DATA_11 pair drm/amd/powerplay: refine powerplay code. drm/amd/powerplay: delete dead code in hwmgr.h drm/amd/powerplay: refine interface in struct pp_smumgr_func ...
