Eric Anholt ec111d70fe Convert BSD code to mostly use bus_dma, the dma abstraction for dealing 
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.

Eric Anholt 10ddbc8c8c Use /*- to begin license blocks in BSD code to reduce diffs against FreeBSD 
CVS.

Eric Anholt c9202c8965 Commit WIP of BSD conversion to core model. Compiles for r128, radeon, but 
doesn't run yet. Moves the ioctl definitions for these two drivers back
    to the shared code -- they aren't OS-specific.

Eric Anholt 0cf1887139 - SMPng lock the DRM. This is only partial -- there are a few code paths 
used by root (the X Server) which are not locked. However, it should
    deal with lost-IRQ issues on -current which I think people have been
    experiencing but I am unable to reproduce (though I understand why they
    would occur, because of a bug of mine). Note that most of the locking
    (DRM_LOCK()/UNLOCK()) is all covered by Giant still, so it doesn't
    matter yet.
- Remove locking on FreeBSD-stable and NetBSD. These are covered by the
    fact that there is no reentrancy of the kernel except by interrupts,
    which are locked using spldrm()/splx() instead.

Eric Anholt ad78a613a4 - Remove $FreeBSD$ tags as they weren't too useful and merges are now being 
done through perforce.
- Add copyright headers to drm_os_*bsd.h, still need to research the other
    copyright-less files better.

Eric Anholt 766a1da2e5 Remove the map argument from DRM_*MEMORYBARRIER. Not all of the uses of 
DRM_*MEMORYBARRIER we had were related to an MMIO space. This means
    arch-specific code on the BSDs, unfortunately. Also add
    DRM_MEMORYBARRIER() and change the DRM_READMEMORYBARRIER()s that used
    to be read/write barriers to it.

Eric Anholt 0bd0dd2300 Merge back from FreeBSD-current, adding FreeBSD ID tags to aid future 
merging. Also includes an update to radeon PCI IDs.
