        src/sys/external/bsd/drm/dist/bsd-core: drmP.h drm_pci.c

Log Message:
- for DRM_NETBSD_HANDLE2ADDR/ADDR2HANDLE, do what uvm does to recover
the virtual address from a uoffset, e.g. uoffset + vm_map_min(kernel_map).

- Eliminate the bus_space_read/write-based DRM_READ/WRITE macros.  The
  memory we're reading/writing from is not always allocated with bus_space,
  and so this will not do.  Instead, since all of our bus_space maps are
  linear, volatile pointer dereferences will do just fine.

- Unify members of struct drm_dma_handle amongst freebsd and netbsd:
  the 'addr' member was superfluous; also, set dmah->tag from
  dev->pa.pa_dmat and use that.

- we don't need BUS_DMA_ALLOCNOW, as bus_dmamap_load is called immediately
  following bus_dmamap_create(), so there's no need to avoid deferring
  allocation to load time.

- Add check for nsegs != 1 in drm_pci_alloc().

- We don't need the DRM_PCI_DMAADDR macro right now--it was only
  used once.
