zero does not mean no privs, instead it grants write access
_DRM_READ_ONLY only applies to non-root users. Problem is only in CVS,
initmaps are not in the kernel yet.

sleep-with- mutex held. This probably ought to be an os-independent

FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff
doesn't need to be in shared code.
- Fix mach64 build by using __DECONST to work around passing a const
pointer to useracc, which is unfortunately not marked const.
- Get rid of a lot of maplist code by not having dev->maplist be a pointer,
and by sticking the link entries directly in drm_local_map_t rather
than having a separate structure for the linked list.
- Factor out map uninit and removal into its own routine, rather than
duplicating in both drm_takedown() and drm_rmmap().
- Hook up more driver functions, and correct FreeBSD-specific bits of
radeon_cp.c, making radeon work.
- Baby steps towards using bus_space as we should.

to the shared code -- they aren't OS-specific.

Ups radeon to version 1.12.0, Vladimir, you might want to add any extra
pciids...

a busid that doesn't correspond to the device the DRM is attached to.
This is a breaking of backwards-compatibility only for the
multiple-DRI-head case with X Servers that don't use interface 1.1.
- Move irq_busid to drm_irq.h and make it only return the IRQ for the
current device. Retains compatibility with previous X Servers, cleans
up unnecessary code. This means no irq_busid on !__HAVE_IRQ, but can be
changed if necessary.
- Bump interface version to 1.2. This version when set signifies that the
control ioctl should ignore the irq number passed in and enable the
interrupt handler for the attached device. Otherwise it errors out when
the passed-in irq is not equal to the device's.
- Store the highest version the interface has been set to in the device.
- Fix a recursion on DRM_LOCK in irq_uninstall on FreeBSD. This leaves
irq_uninstall being done without the lock in some cases, but it was
racey anyways.

the 2D driver initializes MC_FB_LOCATION and related registers sanely
the DRM deduces the layout from these registers
clients use the new SETPARAM ioctl to tell the DRM where they think the
framebuffer is located in the card's address space
the DRM uses all this information to check client state and fix it up if
necessary
This is a prerequisite for things like direct rendering with IGP chips and
video capturing.

from __HAVE_DMA. This will be useful for adding vblank sync support to
sis and tdfx. Rename dma_service to irq_handler, which is more
accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
the right number of underscores. This may have been a problem in the
case that the server died without doing its DRM_IOCTL_CONTROL to
uninit.

irq handler in DRM(irq_install). Modify all drivers to ensure irq
handler is removed before cleanup and cleanup is called at takedown.
Remove unused buffer private struct fields in i810, i830. Check for
lock on init/cleanup in all drivers except i810/i830. The current DDX
for i810 and i830 doesn't hold the lock on kernel init (FIXME?).

use correct address for ring read pointer writeback (yes, we seem to have
been running with bogus values for the ring read pointer, which
'worked' because the return value of radeon_wait_ring() is never
checked and the ring usually never fills up)
