This looks great.

As you mention some platforms return zero, for example sparc32,
for get_cycles().

I suggest we just expand the dependency list for NET_SCH_CLK_TSC
to include SPARC64 PPC64 and perhaps some other easy to verify
as having a working get_cycles() implementation.  I believe that
as long as it increments at some rate >= jiffies, the psched
calibration will get things into a working state.

A lot of patches have been posted in this area and I'm losing
track of what to apply first etc.  Can you repost your work
one change at a time?  Thanks.
