+Subject: [PATCH 0377/1110] drm/amdgpu: Fix two bugs in
+ amdgpu_vm_bo_split_mapping
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Off-by-one: last is inclusive, so the maximum is start + max_size - 1
+Wrong unit: addr is in bytes, max_size is in pages
