Naga Chumbalkar 8588d10671 oprofile/x86: add comment to counter-in-use warning ...

Currently, oprofile fails silently on platforms where a non-OS entity
such as the system firmware "enables" and uses a performance
counter. There is a warning in the code for this case.

The warning indicates an already running counter. If oprofile doesn't
collect data, then try using a different performance counter on your
platform to monitor the desired event. Delete the counter from the
desired event by editing the

 /usr/share/oprofile/<cpu_type>/<cpu>/events

file. If the event cannot be monitored by any other counter, contact
your hardware or BIOS vendor.
