3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Chris Wilson <[email protected]> commit 27c1cbd06a7620b354cbb363834f3bb8df4f410d upstream. The 845g shares the errata with i830 whereby executing a command within 2 cachelines of the end of the ringbuffer may cause a GPU hang.
