- u_render-Cast-color-masks-to-unsigned-long-before-shifting-them.patch:

Make sure result of shift operation fits into type of variable. This
  fixes finding the correct visual for RENDER with a BGRA framebuffer
  (bnc#876757).

+Subject: [PATCH]render: Cast color masks to unsigned long before shifting them
+Patch-mainline: to be upstreamed
+Git-commit: 6ec9a78f9b79668239c3a1519d715cbecf186cef

+
+The color masks in DirectFormatRec are CARD16. Shifting them may lead
+to unexpected results. Cast them to unsigned long to make sure the
+shifted value will still fit into that type.
