Subject: [PATCH 00/10] clocksource_register_khz/hz cleanups (for 2.6.38)

clocksource_register_hz/khz() properly calculates a 
clocksource mult and shift value for a clocksource,
removing much of the copy/pasted or arch-specific helper 
functions that do so.

The common x86 clocksources have been converted to use
clocksource_register_hz/clocksource_register_khz and I've
seen no related bug reports, so I think the infrastructure
is fairly sound. So I wanted to start consolidating the
other arches to also use the clocksource_register_hz/khz
method.

I was a bit too late sending some of these patches out for
the 2.6.37 cycle, so I wanted to send these out early for 
2.6.38.

While all of these patches are untested, they are pretty
straight forward, so please consider including these into
your 2.6.38 queue for testing.

thanks
-john
