Even after this change there's a stale reference to ->break_handler():

  arch/x86/include/asm/kprobes.h:  * a post_handler or break_handler).

Please use 'git grep'!

Also, there's no reason to send an incomplete series: please remove _all_ 
->break_handler() references so that it's 100% gone! The pain of having and not 
having ->break_handler() is completely unnecessary.

Thanks,
