Move the arm version of the kprobes instruction parsing code into more generic files from where it can be used by uprobes and possibly other subsystems. The symbol names will be made more generic in a subsequent part of this patchset. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
