Release 2.20.18 (2013-01-16)
============================
A bunch of miscellaneous fixes for assertion failures and various
performance regressions when mixing new methods for offloads, along with
a couple of improvements for rendering with gen4.
* Remove use of packed unnormalized texture coordinates on gen4/5 as
these GPUs do not support unnormalized coordinates in the sampler.
* Remove dependency upon x86 asm for cross-building to unsupported
architectures.

* Apply damage around PRIME updates in the correct order.
* Correctly read the initial backlight level for when the user
overrides UXA's choice of backlight controller.
* Throttle UXA and prevent it queuing work much faster than the GPU can
complete it. This realised itself in impossible performance figures and
the entire display freezing for several seconds whlist the GPU caught
up. One side effect is that it also caused the DDX to consume more
memory than was required as it could not recycle buffers quick
enough, and in some cases this produces a marked improvement in
performance. Also note on gen2/3 this requires a new libdrm [2.4.41]
in order to prevent a bug causing the DDX to fallback to swrast.

A minor update to prepare for co-operating with the kernel over managing
