2.6.5-rc3-mjb2

From: Martin J. Bligh
Date: Fri Apr 02 2004 - 12:56:06 EST


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.
