6971be783b util: Improve the cpuid assembly. 
No need to save ebx on 64bit. Use just xchgl. Refer to gcc's cpuid.h header.

Thanks to Uros Bizjak for pointing this out.

75e0a376cd mesa: Copy textures' base format into wrapper renderbuffer. 
Otherwise st_copy_texsubimage will fallback to software blit due to
inconsistent base formats.

1336989ec6 st/dri: no need to request fake front buffer, only handle it being returned 
The previous behaviour was incorrect, and resulted in EXT_tfp being broken
for DDX drivers that implement the correct behaviour (intel/radeon/nouveau).

In the cases where a fake front buffer is required, the X server will
return one when requesting __DRI_BUFFER_FRONT_LEFT.

The Xorg state tracker (aka modesetting_drv) is likely broken now until
it's modified to match the other drivers.

7a2271c659 util: Make assert a no-op on non-debug builds. 
This ensures that an assertion like

  assert(expensive_test());

won't have any penalty on release builds. It also implies that no vital
code should be in assert expressions.

589ec337f0 llvmpipe: Autogenerate lp_tile_soa.c from u_format.csv. 
This is just a temporary change until we code generate the tile read/write
functions in runtime. The new code avoids an extra memcpy that exists in
u_tile.c functions, from which lp_tile_soa.c was originally based.

This achieves up to 5% improvement, particularly in frames with
little geometry overlap.

bbe384c86a r300: Workaround problem on R500 with very large fragment programs 
The non-KMS interface is to blame here. In theory, a proper fix
could be produced that works for the KMS interface only, but it
require cleaning a lot of mess. Easier to just do it right in r300g.

918199fb0f mesa/st: don't reuse vertex buffers for bitmap, clear quads 
Currently using max_slots > 1 will cause synchronous rendering
if the driver flushes its command buffers between one bitmap and the
next.

Need to improve buffer_write to allow NO_WAIT (as well as no_flush)
updates to buffers where we know there is no conflict with previous
data.
