Subject: [PATCH 0/7] clocksource_register_khz/hz cleanups(for 2.6.37?)

So the common x86 clocksources have switched over to using 
clocksource_register_khz/hz() and so far I've seen no bug
reports, so I wanted to post the conversion for a few more
architectures so they can be queued up for 2.6.37 (or later
if the maintainer feels more testing would be good).

These changes greatly simplify clocksource registration,
removing much of the copy/paste voodoo surrounding how
to calculate good mult and shift values for clocksources.

While the patch set is numbered here, the patches are not
dependent on each other. So each maintainer can make an 
independent call on merging for 2.6.37.

The conversion is fairly straight forward. However, I have 
not been able to test these, so I'd appreciate any testing 
or feedback. Any assistance from the maintainers in getting
these into their trees would also be greatly appreciated.

thanks
-john
