Cover letter [PATCH 00/12] jump label v10
Hi,
updates in -v10:
*removed build-time jump table sort. Since I moved to faster lib/sort.c qsort
method, the run-time sort is really fast. This change also reduces the complexity quite a bit.
*added arch_jump_label_text_poke_early(), removing text_poke_early() in generic code.
I think for most arches this should be a no-op.
*various Sparc cleanups and build testing on x86_64 using the 4.5 sparc64 cross
compiler for both 'asm goto' enabled/disabled cases.
*re-ordered the patches, so as to separate out arch bits cleanly
*various cleanups - incorporating last round of feedback and docs update
Special thanks to Tony Breeds for helping me with the sparc64 cross compiler 4.5 toolchain.
thanks,
-Jason
