Add a function to free buffers on hold for destruction if their
fence object has expired.
Add a timer to periodically call that function when there are
buffers pending deletion.
0x10000000 to 0x90000000 in PAGE_SIZE increments.
Implement hashed map lookups.
This potentially breaks both 2D and 3D drivers. If so, the corresponding
2D and 3D driver should be fixed, and it's corresponding drm device driver
should have its major bumped as soon as possible.
Bump sis and via drm device driver majors.
The SiS and Unichrome 3D drivers are fixed in Mesa CVS HEAD and
mesa_6_4_branch.
drm_mtrr_{add,del} for handling the MTRR setup. Still has a LOR issue
with DRM_VERIFYAREA_READ/DRM_COPY_FROM_USER_UNCHECKED in savage_bci.c
-- this won't work with the fine-grained locking in use, and just doing
a single copyin to a temporary will probably work fine. Also note that
the module leaks approximately 4 kb on unload.
radeon_cp.c to use a drm_local_map_t-type mapping (drm_core_ioremap
rather than drm_ioremap), which contains private device mapping
information on BSD. I also changed the ati_pcigart interface to use
"void *" for pointers to kva rather than "unsigned long". While PCIGART
support appears to be broken on FreeBSD currently, I think this is not
new, and BusType PCI remains working on my r100 in Linux.
drm_agp_foo_ioctl pair. Modifies the MGA DRM to use the drm_agp_foo
functions instead of the drm_foo_agp functions. The drm_foo_agp
functions are no longer exported by drm.ko.
Ensures that dma->seg_count and dma->page_count are properly set in
drm_addbufs_{agp,sg,fb}. drm_addbufs_pci was already correct.
Ensures that mga_do_agp_dma_bootstrap correctly sets agp_buffer_token.
At this point PCI DMA is still broken.

can register allocations on other clients or free memory used by other
clients which will lead to severe memory manager inconsistensies.

postinit and version were replaced with generic code in the Linux DRM
(drivers now set their version numbers and description in the driver
structure, like on BSD). postsetup wasn't used at all. Fixes the savage
hooks for initializing and tearing down mappings at the right times.
Testing involved at least starting X, running glxgears, killing
glxgears, exiting X, and repeating.
Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
