[PATCH v2 00/01] arm: ftrace: Adds support for CONFIG_DYNAMIC_FTRACE_WITH_REGS

[Jean-Jacques Hiblot]

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
