2.6.2-mjb1

From: Martin J. Bligh
Date: Wed Feb 11 2004 - 15:46:22 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. Updated arch support for AMD64 + PPC64.
4. Better support for sound, especially OSS emulation over ALSA.
5. Better support for video (v4l2, bttv, ivtv).
6. Kexec support.

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