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 Sat, Mar 13, 2010 at 12:19:44PM +0530, Rabin Vincent wrote:
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
