[PATCH 2/7] arm: ftrace: Add call modify mechanism

2016-12-06 Thread Abel Vesa
Function ftrace_modify_call provides a way to replace ftrace_stub with the ftrace function. This helps the klp_ftrace_handler to be called via ftrace_ops_no_ops, which in turn will set the pc with the patched function's starting address. This is used for livepatching. Signed-off-by: Abel Vesa ---
