    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
