Linux Scalability Effort

The patchset is meant to be pretty stable, not so much a testing ground.

1. Better performance & resource consumption, particularly on larger machines.
2. Diagnosis tools (kgdb, early_printk, etc).

I'd be very interested in feedback from anyone willing to test on any 
platform, however large or small.
