Subject: [PATCH v4 10/16] ARM: Change more ARM kprobes symbol names to something more

From: "David A. Long" <dave.long@...aro.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@...aro.org>
