This series converts x86_64 timers to clockevents drivers and then

lapic broadcast mechanism is untested, I'm sure it still needs work,
there's still some cruft in lapic_setup_timer.

This is just for comments at this point, now that it's working on my
test box in both NO_HZ=n and NO_HZ=n configurations (typically using
hpet).

hm, neat - did you take a look at the x86_64 clockevents code that is in
-rt and that has been there for a year or so and has been tested quite
extensively?

Yes, that's what I started with. It was only partially done, for example,
didn't have hpet done yet and didn't work well on my machine (hang
on boot). As I dug at it, there was still more room for cleanups, etc.
Hence this, which has also been tested somewhat extensively as Jeremy
noted from my typo above... Both NO_HZ=n _and_ NO_HZ=n ;-)

thanks,
