Subject: [RFC][PATCH 0/6] xtime/wall_to_monotonic cleanups

This patchset cleans up all the direct accesses to xtime
and wall_to_monotonic, allowing them to be made static
so we can do further cleanup and rework of the timekeeping
core.

This is 2.6.36 (or later) material. But I wanted to get 
the ball rolling.

Any feedback/testing would be greatly appreciated!

thanks
-john
