[PATCH 00/12] jump label v10

[Jason Baron <jbaron@redhat.com>]

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
