    - 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.
