Subject: drm/amdgpu: cleanup mtype mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 71776b6daef66b6d7afdd404c2175dbcac7e1a05
Patch-mainline: v5.5-rc1
References: bsc#1152489
Unify how we map the UAPI flags to the PTE hardware flags for a mapping.
Only the MTYPE is actually ASIC dependent, all other flags should be
copied over 1 to 1 and ASIC differences are handled later on.
