fix the module class.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Delete the do-nothing device-activation hook, drm_activate().

this fixes restarting X + drm after actually using drm.

convert a DRM_ERROR() to DRM_DEBUG(). its failure is not fatal
and it tends to trigger on almost all cards.

some minor clean up:
- reduce diffs to mesa-drm where possible
- fix various formatting issues
- netbsd uses major 180 for drm (XXX)

with our changes and the work recently done by Arto Huusko
<arto.huusko@pp2.inet.fi> and FUKAUMI Naoki <fun@naobsd.org>.

it includes all the changes arto provided from both mesa-drm and
the r6xx-r7xx-support branch. it does not yet include code to
handle the (deleted) drm_pciids.h file, but i'll probably just
check in a generated one for now.

i have not yet merged the changes from outside this dir.


from arto's messages to tech-x11:

The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.

Other changes:

- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers

- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared

Don't attempt to unload a DRM device that's in use. (Note:
Unloading doesn't work right in any case -- it doesn't clean up the
sysctl tree, among other things. This code needs Work, but at least
this prevents it crashing randomly due to autounload while X is
running.) Also, fix the dependency list for radeondrm.

Remove #ifdef __FreeBSD__ around DRM_UPDATE_DRAW ioctl, as we have drawable
code (and if it does not work, we must make it work!).

Add missing entry for DRM_MODESET_IOCTL.

add forgotten initialization/destruction for tsk_lock.

PCI_PRODUCT works on pa_id, not pa_device

dev->pci_device should be assigned PCI_PRODUCT(pa->pa_id), not the id
itself.

set dev->kdev = kdev at open time, not in drm_ioctl.

Implement drm_drawable gunk and drm_locked_task, untested. i915drm links now.

this still has a lot to go. it doesn't work yet, but it's getting
close.

most of this is from other authors than myself: yorrick, drochner,
jared, bjs, all contributed a lot more than i have so far, but there's
a bunch of clean up from myself in here as well.
