+Release 2.21.3 (2013-02-20)
+===========================
+A few minor bugfixes, another point release.
+
+ * Fix tracking of DRI pixmaps and their backing bo across reparenting. If
+ we tried to execute a SwapBuffers after a Window was reparented, but
+ before the DRI client has updated its references, then we would end up
+ manipulating an exported pixmap without a flush flag set. In the worst
+ case, this would culminate in a segfault in the driver.
+
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497
+
+ * Restore the gen4 workarounds for flickering rendering - a few cases still
+ remain, as the root cause persists.
+ https://bugs.freedesktop.org/show_bug.cgi?id=60402
+
+ * Double check that the device has KMS enabled before claiming. This allows
+ X to gracefully fallback to VESA/fbdev rather than bailing out.
+ https://bugs.freedesktop.org/show_bug.cgi?id=60987
+
+ * Fix the UXA render programs for projective transforms on Ivybridge.
+
+

sna/trapezoids: Perform the cell allocation upfront
As we know the maximum extents of the trapezoids, we know the maximum
number of cells we will need and so can preallocate them.

sna: Assert that the GPU damage is NULL before destroy a proxy
If the GPU bo is a proxy, then it really is a pointer into a upload
buffer for CPU data. In these cases, there should never be any GPU
damage lying around.

sna/dri: Prevent swapping a decoupled DRI2Buffer
If the DRI2Buffer is no longer valid for the Drawable, for example the
window had just been reparent, just complete the swap without triggering
any assertions.

uxa/gen7: Don't use a message register to store vl
Turns out the "new" assembler that uses mesa's opcode emission hits the
path that automatically transforms MRF registers into GRF ones in the
exa_wm_src_projective shader.
The diff with the new assembler is:
$ intel-gen4disasm -g7 -
- { 0x00600041, 0x208077be, 0x008d03c0, 0x008d0180 },
+ { 0x00600041, 0x2e8077bd, 0x008d03c0, 0x008d0180 },
