Ok I've resynced all the patches with 2.6.13-mm1, made some cleanups and minor 
modifications. As pm timer is the only supported timer for dynticks I've also 
made it depend on it.

A rollup patch against 2.6.13-mm1 is here:

http://ck.kolivas.org/patches/dyn-ticks/2.6.13-mm1-dtck1.patch

also available in the dyn-ticks directory are the older patches and these 
split out patches posted here.

Cheers,
Con
