Subject: drm/amdgpu: Fix the exported always on CU bitmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: dbfe85ea496728ccf7731601084853f760be77d7
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Newer asics with 4 SEs are not able to fit the entire bitmask in the
original field, use an array instead.
v2: keep cu_ao_mask for backward compatibility.
