I notice that the userspace stuff in CVS assumes perfmon3 has 7 system
calls, the 5 added here plus pfm_create_sets and pfm_getinfo_sets.
Are you planning to add those two later (in which case we should
reserve the numbers now), or are you going to implement the
functionality of those two in pfm_write and pfm_read?

Regards,
Paul.
