Merged requested to merge thomash/mesa:banded-dma-fix into master
A previous commit ("winsys/svga: Limit the maximum DMA hardware buffer size") made banded DMA transfer kick in when transfering gnome-shell window contents under gnome-shell / wayland. This uncovered a bug where we assumed that banded DMA transfers always occur to the top (y=0) of the surface. Fix this by taking the destination y offset into account.
