high-precision timers for parisc using cr16

parisc,

After another dicsussion about high-precision timers on parisc and the possible uses of cr16, I decided to write down our ideas so that they are not lost and rehashed.

http://wiki.parisc-linux.org/Time?action=show

I'm looking for comments. In particular from kernel hackers about implementing the cr16 offset table. If someone wants a small project that would be cool to work on. I would make myself responsible to finish the userspace pieces and then we would have nanosecond timing using get_cycles (independant library) or clock_gettime (nsec field filled from cr16).

c.
