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
