Linux 2.5.18-dj1

Linux 2.5.18-dj1

[Dave Jones]

Resync against 2.5.18, and go through the pending patches folder.
Mostly compilation fixes, but a handful of useful bits too.
A lot of the pending stuff doesn't apply any more, so it may
take a while for me to get around to applying. (ie, resending
resynced versions of patches you sent me may be quicker)

As usual,..

Patch against 2.5.18 vanilla is available from:
ftp://ftp.kernel.org/pub/linux/kernel/people/davej/patches/2.5/

Merged patch archive: http://www.codemonkey.org.uk/patches/merged/

Check http://www.codemonkey.org.uk/Linux-2.5.html before reporting
known bugs that are also in mainline.

        I seem to be bringing a shitload of bad news to the list. :) Anywho, 
got this with booting -dj1. Oops was handwritten, and thrown through ksymoops:

This oops has existed over several 2.5 versions.  The following was thrown
around to fix it (I don't remember who though).

That looks like my patch.  It stops the oops (by fixing a signed
vs. unsigned comparison bug) but doesn't fix the colormap handling.
On my G4 powerbook, which has an ATI Rage 128 (Mobility M3 AGP 2x) the
screen colours are all totally wrong under X when I boot 2.5.18.  I
have Option "UseFBDev" in my /etc/X11/XF86Config-4, so the X server is
using the kernel frame buffer driver to do colormap updates.  (The
colours are all OK on the text consoles though.)

Where is the latest ATI 128 driver? I like to port it over to the new api.

I going to push the fix very soon to linus. I have a bunch of new updates.
