This patch adds support for ftrace operations on the ARM architecture. This support is needed by kgraft and possibly other ftrace-based tools. My goal is to have kgraft working on ARM and aarch64.
I tested this patch with a toy implementation of kgraft for ARM and basic usage of function and function_graph tracers It doesn't show any problem with the ftrace selftests and the tests found today in branch ftrace/testing-mystuff of linux-trace repository (git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git)
change since v1: - changed the title and the commit log of the patch to make it more understandable
