2.6.7-mjb1

2.6.7-mjb1

[Martin J. Bligh]

The patchset is meant to be pretty stable, not so much a testing ground.
Main differences from mainline are:

1. Better performance & resource consumption, particularly on larger machines.
2. Diagnosis tools (kgdb, early_printk, etc).
3. Kexec support.
4. ivtv drivers

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