Comment(by fweisbec):


 Could you please test the above patch, it will disable tracing on those
 naked functions.
 Note that it applies on 2.6.28 (original) so tell me if it applies not
 well on the openmoko kernel.

 It's not a smart one, just to test. If it works, it would be better you
 redefine the __naked macro with "no_instrument_function" attribute and
 "naked" and replace all __attribute__((naked))__ by __naked (should
 perhaps even be done in mainline).
