This is an RFC patch set that makes gcc use the -mfentry option with
-pg. This will set the ftrace 'hook' to the beginning of the function
and also remove the requirement that -pg enables frame pointers.
This has a couple of benefits (and probably more).
1) removal of the frame pointer

and also remove the requirement that -pg enables frame pointers.
