Module Name:    src

Modified Files:
        src/sys/dev/drm: drmP.h drm_auth.c drm_bufs.c drm_drv.c drm_irq.c
            drm_memory.c drm_pci.c drm_scatter.c drm_vm.c files.drm

Log Message:
- Use the extent manager to track mappings and provide sane offset
  "cookies" for mmap.  Now the radeon driver works on amd64!

- Use bus_dma for nearly all map types (carried over from prior patch).

- Plug some lock leaks in drm_bufs.c and remove superfluous locking in
  drm_add_magic() (from git).

- Lower spl of mutexes to IPL_NONE (and so are now adaptive instead of
  spin mutexes), save for irq_lock which is a spin mutex at IPL_VM.
  Use mutex_spin_enter()/mutex_spin_exit() for irq_lock.
