Thank you for the patch, testing on a 2.5.64 kernel (I don't have 2.5.67
yet :-) ) with and without preempt.

For now I would say it doesn't work :-( I get the same results from
realfeel4 than before.
However it works better (in a point of view) than before because now
pfm_ovfl_block_reset() is called and sends a SIGPROF. But this is done
only at the very end of realfeel4, according to the logs I think it's
when sending the SIGALRM.

Sorry, I hadn't noticed, I'm now cross-posting.
