This is a useful fixup for some of the g4x ring initialisation woes, but as usual, not all. v2: Do the rewrite unconditionally anyway To generate a diff of this commit: cvs rdiff -u -r1.5 -r1.6 \ src/sys/external/bsd/drm2/dist/drm/i915/intel_ringbuffer.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
