Subject[PATCH v4 08/16] ARM: Use new opcode type in ARM kprobes/uprobes code
Date
From: "David A. Long" <dave.long@linaro.org>

For any ARM kprobes/uprobes code interfacing to the generic ARM probes code
use a new probes_opcode_t type to avoid a dependency on kprobes definitions.

Signed-off-by: David A. Long <dave.long@linaro.org>
