Allow it to sleep waiting for resources during the allocation stage.
Only use BUS_DMA_NOWAIT when loading the map.

ati pci gart to use bus_dma to handle the allocations. This fixes
a garbled screen issue on at least some radeons (X1400 tested).

Allocate memory from different pools. This allows the OS to track memory
allocations for us, much like the linux memory debugging. This will ease
tracking down memory leaks since the OS can track the number of allocations
from each pool and help to point us in the right direction. Also replace
drm_alloc and friends with static __inline__ versions while we are here.

The brief descriptions usually had the wrong filename in them.

The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures. This also means that XFree86 4.2.0 support for i810 DRM
is lost.

With this, all modules build again.

with IOMMUs and such. There is one usage of the forbidden vtophys()
left in drm_scatter.c which will be fixed up soon. This required a KPI
change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
keeps track of os-specific bits, rather than just passing around the
vaddr/busaddr/size.

ioctls with dev_lock, which is a major step toward being able to remove
Giant. Covers some new pieces (dev->unique*) in the core, and avoids
one call down into system internals with the drm lock held, which is
usually bad (FreeBSD LOR #23, #27).

using drm_alloc/drm_free in the core and instead use plain malloc/free.

doesn't run yet. Moves the ioctl definitions for these two drivers back
to the shared code -- they aren't OS-specific.

done through perforce.
- Add copyright headers to drm_os_*bsd.h, still need to research the other
copyright-less files better.

merging. Also includes an update to radeon PCI IDs.
