SubjectRe: [PATCH 07/10] ftrace: pass KBUILD_CFLAGS to record_mcount.pl
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.

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
