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
