Subject: combine per-cpu trace files

Hi Steven,

Regarding trace-cmd I have a question about the trace files. While
debugging an driver issue I had trace-cmd recording driver events on the
target system until it crashed and I had to power down the machine. Now
I have three trace-cmd files: trace.dat, trace.cpu1 and trace.cpu2.
trace-cmd combines the per-cpu files into final trace.dat, but would it
be possible to do that as a separate post process after a crash/abort.

Regards,
Arend
