[Intel-gfx] [PATCH 00/17] gtt rework, part2 : pte handling

[Daniel Vetter]

Hi all,

The next part of my intel gtt rework. This creates a new abstraction
for the pte handling, resulting in:
- A generic fake agp driver for all chipsets (save the poor bastard i81x).
- Less indirection hell for the pte writing (a simpel write_entry instead
  of iowrite32(mask_memory(type_to_mask))).

Of course there's still a bit left to clean up in intel-gtt.c (Chris Wilson
is busy adding things to my todo list). But I think this is a nice cut
point for the current release cycle. The next one can then concern itself
with better integration with gem and a few other loose ends on a hopefully
well-tested basis.

As usual, tested on i855 (with -fixes merged in), i945 and my ilk. Comments
highly welcome. Altough I refuse to accept responsability for headaches
from reading the (old) code in intel-gtt.c ;)

Yours, Daniel
