3.2.48-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Ben Hutchings <b...@decadent.org.uk> This reverts commit 393143615d9f2f581d87387268dc11b95adc339c, which was commit f05bb0c7b624252a5e768287e340e8e45df96e42 upstream. This has been found to cause GPU hangs when backported to 3.2, though not in mainline.
