+Subject: [PATCH] mi: sprite: SaveUnderCursor2
+
+There is cursor bleeding for the devices which try to acclerate the
+Desktop environment using low powered ARM Mali GPUs. The area under
+the cusrsor is not updated for every swap call within the armsoc,
+resulting in the block artifact.
+
+Expose miDCSaveUnderCursor2 API, so that other graphics layer like
+armsoc can inoke and save the area under the cursor before actually
+performing a swap between the backbuffer and the frontbuffer.
