Just a quick note...
> From: Ray Strode <rstrode at redhat.com>
> lp_build_fetch_rgba_soa fetches a texel from a texture.
> Part of that process involves first gathering the element
> together from memory into a packed format, and then breaking
> out the individual color channels into separate, parallel
> The code fails to account for endianess when reading the packed
> This commit attempts to correct the problem by reversing the order
> the packed values are read on big endian systems.

If consensus is this patch is good enough for now, then it's, of course,
