[RFD] Time rework [take #2]

[Franck Bui-Huu <vagabon.xyz@gmail.com>]

OK, I don't get any feedbacks since my original post but I had time to
make some changes...

It's now based on "linux-2.6.22-rc4-357-g7518784", with a part of Ralf's
linux-time patches.

I'd like to port some 'interesting' platforms as a proof of
concept. Could anybody name them ? I'd like to port a platform that
uses the 'hpt' as clock source and timer. A second one that uses the
hpt only as a timer, and a third one that doesn't uses it at all. A
small description can help too...

Thanks

		Franck
