mesa-10.4.4 fails when trying to apply patch mesa-10.3.7-dont-use-clrsb.patch. As can be seen from the mesa-10.3.7-dont-use-clrsb.patch.out I have attached (and after inspection of the original src/gallium/auxiliary/util/u_math.h) the #if defined .. #else #endif lines the patch tries to remove aren't present in the original file in this version, so I guess the patch isn't needed for 10.4.4

This seems to be related to bug #538086
I'm leaving this bug open for a bit to prevent duplicate reports.

It must be on or after
