Release 2.21.4 (2013-03-11)
===========================
More bugs, more fixes, more releases. A minor new feature being introduced
is the runtime detection of CPU instructions sets along with specialised
paths to take advantage of the available CPU.

 * Honour LinearFramebuffer for clumsy PowerXpress integration

 * Disable read-read optimisations of mappings whilst the root
   cause of a corruption issue remains elusive.
   https://bugs.freedesktop.org/show_bug.cgi?id=61628

 * Disable 8-bpp framebuffers in UXA as the regressions therein
   remain unfixed.

 * Restart vertex checks after lock contention
   https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576

 * Handle Screen Pixmap recreation whilst exported via PRIME.

 * Correct application of scale factors to video source offsets.
   https://bugs.freedesktop.org/show_bug.cgi?id=61610

 * Chain up CloseScreen so that resources are actually freed across regen
   https://bugs.freedesktop.org/show_bug.cgi?id=56608

 * Fix Haswell CRW PCI-IDs

 * Handle batch submission failure during DRI copies
   https://bugs.freedesktop.org/show_bug.cgi?id=61708

 * Probe for kernel support of requested Screen depth
   https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403

 * Correct GPU limits for early gen2 and gen3 architectures and prevent
   an infinite recursion for particular image sizes.
