In commit e517a5e970 the call to
map_page_into_agp() got removed from intel_i830_setup_flush(), but the
counterpart call from intel_i830_fini_flush() to unmap_page_from_agp()
was left in place.
Additionally, the page allocated here never gets its physical address
used for sending to hardware, so there's no need to allocate it with
GFP_DMA32. Nor is __GFP_ZERO really necessary, as the page is used
only to store data to force flushing of some internal processor state.

The intel gtt fake agp driver is the only agp driver to use dma
address remapping. So it makes sense to fold this code back into the
only user (and thus reduce the reliance on the agp code).
This patch does the first step by initializing (and remapping) the
scratch page in a new function intel_gtt_setup_scratch_page.
Unfortunately intel_gtt_cleanup had to move to avoid a forward
declaration. The new scratch page is not yet used, though.
v2: Refactor out scratch page teardown. Suggested by Chris Wilson on
irc. This makes it clear what's going on and results in a nice
symmetry between setup and teardown.

The file names are somehow misleading as the code is not specific to
AMD K8 CPUs anymore. The files accomodate code for other AMD CPU
northbridges as well.
Same is true for the config option which is valid for AMD CPU
northbridges in general and not specific to K8.

So far we only provide num_k8_northbridges. This is required in
different areas (e.g. L3 cache index disable, GART). But not all AMD
CPUs provide a GART. Thus it is useful to split off the GART handling
from the generic caching of AMD northbridge misc devices.

Use the detection from intel-gtt.ko instead. Hooray!
Also move the stolen mem allocator to the other gtt stuff in dev_prv->mem.
v2: Chris Wilson noted that my error handling was crap. Fix it. He also
said that this fixes a problem on his i845. Indeed, i915_probe_agp
misses a special case for i830/i845 stolen mem detection.

This way create_gatt_table become dummy glue functions for the fake
agp driver - rename them accordingly (and kill the now unnecessary
i9xx copy).
With this change, the gtt initialization code is almost independant
from the agp stuff. Two things are still missing:
- the scratch page is created by the generic agp code.
- filling the whole gtt with scratch_page ptes is not yet consolidated -
this needs abstracted pte handling, first.

Same idea as INTEL_INFO from drm/i915. This
- reduces the dependancy on agp_driver
- stops the what-does-IS_I965G-mean confusion (here it's just gen4, in
drm/i915 it's gen >=4)
- further prepares the separation of the fake agp driver from the rest.

In commit f1befe71 Chris Wilson added some code to clear the full gtt
on g33/pineview instead of just the mappable part. The code looks like
it was copy-pasted from agp/intel-gtt.c, at least an identical piece
of code is still there (in intel_i830_init_gtt_entries). This lead to
a regression in 2.6.35 which was supposedly fixed in commit e7b96f28
Now this commit makes absolutely no sense to me. It seems to be
slightly confused about chipset generations - it references docs for
4th gen but the regression concerns 3rd gen g33. Luckily the the g33
gmch docs are available with the GMCH Graphics Control pci config
register definitions. The other (bigger problem) is that the new
check in there uses the i830 stolen mem bits (.5M, 1M or 8M of stolen
mem). They are different since the i855GM.
The most likely case is that it hits the 512M fallback, which was
probably the right thing for the boxes this was tested on.
So the original approach by Chris Wilson seems to be wrong and the
current code is definitely wrong. There is a third approach by Jesse
Barnes from his RFC patch "Who wants a bigger GTT mapping range?"
where he simply shoves g33 in the same clause like later chipset
generations.
I've asked him and Jesse confirmed that this should work. So implement
it.

agp/intel_gtt.c and drm/i915/i915_dma.c don't calculate this the same
way: The intel-gtt code seems to use the actual gtt size, the drm

that's the more conservative choice.
But conserve the original code in intel_gtt_total_size for later use.

This implementation is stolen from drm/i915, but is equivalent to

It's not yet used anywhere, though.
Also introduce intel_gtt_init which only calls intel_gtt_stolen_entries.
