 1.3  12-Sep-2009  drochner fix some confusion between highest DMA address and the boundary not to
be crossed in a transfer,
back out previous fixes which only added to the confusion
 1.2  10-Sep-2009  christos PR/42041: Jasper Wallace: Stopgap fix for kernel assert
("(boundary & (boundary - 1)) == 0") triggers with i915drm in recent -5 kernel

Read the comment in the code for a detailed explanation. This should be fixed
properly in the i386 bus code, but it is too intrusive to do for -5.

merge the changes from drm 85b9f737db0d2a845e4d7e2bbf9ad12ff9e2227c
with our changes and the work recently done by Arto Huusko and FUKAUMI
Naoki.

it includes all the changes arto provided from both mesa-drm and
the r6xx-r7xx-support branch. it does not yet include code to
handle the (deleted) drm_pciids.h file, but i'll probably just
check in a generated one for now.

i have not yet merged the changes from outside this dir.

from arto's messages to tech-x11:

The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.

Other changes:

- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers

- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared
--
add a freshly generated drm_pciids.h
--
some minor clean up:
- reduce diffs to mesa-drm where possible
- fix various formatting issues
- netbsd uses major 180 for drm (XXX)
