Clockevents patch made its way to the kernel(2.6.21-rc1)

Last week (as of 27 Feb 2007) the Clockevents patch made
its way to the kernel(2.6.21-rc1) and took along a modified
version of the kernel timertop. Click in the link of this
post title.

That is great.
The former dyntick implementation (that one mantained by
Con Colivas) was deprecated and was superseded by this new
one which was derived from the real time patch from Red Hat
and Timesys. Surprinsingly timertop was the only part that
remained. Afterwards they ended up removing timertop.c but
have kept a good acknowledge and inspiration note in the new
code, timer_stats.c, as you can see in the link above.

Thanks Ingo Molnar and Thomas Gleixner
