[PATCH] ARM: ftrace: Implement HAVE_FUNCTION_GRAPH_FREGS

[Linus Walleij]

Unsolicited thread intervention:

Richard if you use ftrace on ARM a lot, have you looked into
patchable function entry as described by Mark Rutland for
ARM64 in this talk?

(Described at 19:12 into the talk.)

I think it would be neat if we could do this on ARM32 as well
but I do not know how hard it would be.

Yours,
