[PATCH v7 10/15] ARM: Change more ARM kprobes symbol names to something more generic
David Long

Fri Mar 7 15:10:35 EST 2014
From: "David A. Long" <dave.long at linaro.org>
Change kprobe_emulate_none, kprobe_simulate_nop, and arm_kprobe_decode_init
function names to something more appropriate for code being shared
outside of the kprobes subsystem. Also, move the new arm_probes_decode_init
declaration out of the kprobes.h include file and into the probes.h include file.
Signed-off-by: David A. Long <dave.long at linaro.org>
Acked-by: Jon Medhurst <tixy at linaro.org>
