Subject: [git pull] agp patches for 2.6.25-rc3


Hi Linus,

Please pull the 'agp-patches' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6.git agp-patches

This contains a patch from Arjan to avoid ioremap stupidities in agp, and
adds a warning to catch any others. It also contains an update for the SiS
chipset driver.

Dave.

fix historic ioremap() abuse in AGP

Several AGP drivers right now use ioremap_nocache() on kernel ram in order
to turn a page of regular memory uncached.

There are two problems with this:

1) This is a total nightmare for the ioremap() implementation to keep
various mappings of the same page coherent.

2) It's a total nightmare for the AGP code since it adds a ton of
complexity in terms of keeping track of 2 different pointers to
the same thing, in terms of error handling etc etc.

This patch fixes this by making the AGP drivers use the new
set_memory_XX APIs instead.

Note: amd-k7-agp.c is built on Alpha too, and generic.c is built
on ia64 as well, which do not yet have the set_memory_*() APIs,
so for them some we have a few ugly #ifdefs - hopefully they'll
be fixed soon.
