Hi! it's x86/jumplabel branch, as a followup to commit fd4363fff3d96 ("x86: Introduce int3 (breakpoint)-based instruction patching") sitting there. This branch however seems to be broken by Ingo's mismerge; this e-mail from earlier today: https://lkml.org/lkml/2013/7/22/147 implied that he fixed this ("all is fine"), however x86/jumplabel still contains just 3/3 of Masami's series, and therefore is broken; 3/3 is not enough, it needs also kprobes/x86: Remove an incorrect comment about int3 in NMI/MCE kprobes/x86: Use text_poke_bp() instead of text_poke_smp*() included or kprobes/x86: Remove unused text_poke_smp() and text_poke_smp_batch() functions dropped to be in consistent state again. I pinged Ingo about this: https://lkml.org/lkml/2013/7/22/281 but the branch still seems to be in an odd state, containing last patch of Masami's series.
