single DRM_COPY_FROM_USER rather than DRM_VERIFYAREA_READ followed by
tons of DRM_COPY_FROM_USER_UNCHECKED. I don't like the look of the
temporary space allocation, but I like the simplification in the rest
of the file. Tested with glxgears, tuxracer, and q3 on a savage4.
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.
up a good bit, I think. Also, remove the agp_uninit() function which
has lain around as a noop for years now. The FreeBSD DRM is now all
compiling, with the exception of via. One known sleeping-with-lock-held
issue remains.
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.
firstopen, by making drm_addmap require the drm device lock to be held.
Also, make matching of kernel maps match linux by requiring shm matches
to have the contains_lock flag set if the offset doesn't match.
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.

mga_do_agp_dma_bootstrap fails causes problems if
mga_do_pci_dma_bootstrap succeeds. This commit makes it possible to do
a "minimal" clean up instead. I'm still trying to figure out what is
causing the failures in mga_do_agp_dma_bootstrap...
