Modified Files:
        src/sys/dev/drm: drmP.h drm_dma.c drm_drv.c drm_irq.c drm_lock.c
        src/sys/dev/pci/drm: radeon_cp.c

Log Message:
First round of DRM improvements:  switch to mutex(9), make use of &
operator consistent in locking macros, use mb(9) for memory barrier ops
(to be replaced with bus_space_barrier(9) at a later date; this is not
necessary for x86 but might be for e.g. mips).

More to come.  Try it out!  It's a lot more stable now just with the
mutex(9) changes.
