kernel: handle tos and per process pcycle counters in port/
we might as well handle the per process cycle counter in the portable part instead of duplicating the code in every arch and have inconsistent implementations. we now have a portable kenter() and kexit() function, that is ment to be used in trap/syscall from user, which updates the counters. some kernels missed initializing Mach.cyclefreq.
