Sorry for the late reply, just got back from vacation.

Steven, Frederic,

I'd like to resurrect this old ARM dynamic ftrace patchset.  It still
applies on next except for a small merge conflict in one of the
ARM-specific patches.

On ARM, we have two ABIs, and the ABI used is controlled via a config
option.  Object files built with one ABI can't be merged with object
files built with the other ABI.  So, record_mcount.pl needs to use the
same compiler flags as the kernel when generating the object file with
the mcount locations.  Ensure this by passing CFLAGS to the script.

This is the only non-arch/arm/ patch in the series which doesn't have
either of your Acked-bys, so if you'd be willing to ack it, I'll send in
the lot via rmk's ARM patch system for .37.

Alternatively, this one and "[PATCH 03/10] ftrace: allow building
without frame pointers" could go in via the tracing tree for .36?  Then
I'll send in the ARM specific stuff for .37 via the ARM tree.

Thanks,
Rabin

Hmm, this changes the number of parameters passed to the
recordmcount.pl. shouldn't this be part of the change to
recordmcount.pl? Otherwise, we can break a bisect.
