Subject: ftrace does not work on cpus > 999.

Just started looking into using ftrace to identify a difficult to diagnose
userland set of processes when I noticed that the .../trace/per_cpu
directory only contains entries for cpus 0-999.  I have not looked at
what else may not work.  For the cpus that are listed, I am able to grep
trace buffer information so it is mostly working.

I will be away from email for most of today, but may get back to this
tonight.  If there are any suggestions, I will happily give them a try.

Thanks,
Robin
