[PATCH 0/4] gart cleanups and fixes

[Joerg Roedel]

Hi,

here is a patch-set to clean things up and fix certain issues with the
GART driver in x86-linux. The first patch changes the alignment
requirements for the aperture to be aper_size instead of hard-coded
512MB as discussed in another thread.
Patch two is preperation for patch three which makes sure that the bit
to disable cache probes on gart table walks is always set, even when the
BIOS sets up the aperture correctly and Linux does not remap then.
The last patch adds a check for a GART hardware constraint. The GART can
only map addresses in the first 1TB of physical memory. This is now
checked with the last patch.

Regards,

	Joerg
