this is gets radeon working on amd64 with an older PCI 9250 card.
XXX: need to excise vtophys() usage.
XXX: need to finish porting these fixes to external.
yay! this takes care of one of the XXX's. still not quite working.
- fix a DEBUG message
- apply from sys/dev:

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.

however, this doesn't get radeon working on amd64 here :(

include the size in a falled allocation message.
- use BUS_DMA_ALLOCNOW in bus_dmamap_create() call
- remove a redundant check for NULL

add a comment explaining DRM_NETBSD_ADDR2HANDLE/DRM_NETBSD_HANDLE2ADDR:
* This hack strips the top bit from amd64 addresses, which avoid
* udv_attach() returning NULL for "negative" offset.
* A better hack would be to encode the offset of some kernel data
* structure..
add a new DRM_HANDLE_NEEDS_MASK macro to check whether the above need to
be applied for various mapping types (_DRM_SHM and _DRM_SCATTER_GATHER.)
also:
- use IPL_VM for now
- use a lot of bus_space
- struct drm_device now has a pointer to the device_t

- atime updates were not being synced.
ffs_sync:
- In some cases the sync vnode was acting like now dead /usr/sbin/update.
It was examining vnodes that it should have ignored.
- It would find dirty inodes and try to flush them. Often ffs_fsync()
cheerfully ignored the flush request due to the fsync bug. Such inodes
remained dirty and were repeatedly re-examined by the syncer until
vnode reclaim or system shutdown.
- We were marking our place in the per-mount vnode list even though in
most cases there was not flush to perform. While not a bug, this wasted
CPU cycles because a TAILQ_NEXT would have sufficed.
XXX This must not be enabled by default because the LWP private mechanism
is reserved for TLS. It is provided only as a test/demo.
XXX Since ucontext_t does not contain the thread private variable, for a
short time after threads are created their thread specific data is unset.
If a signal arrives during that time we are screwed.
- No longer need pthread__osrev.
- Rearrange _lwp_ctl() calls slightly.
This will be used to support TLS. The MD method must match the ELF TLS spec
for that CPU architecture (if there is a spec).
At this time it is only implemented for i386, where it means setting the
per-thread base address for %gs. Please implement this for your platform!
Instead, always check ether_type and use appropriate offsets to adjust
the hardware RX sum value.
XXX: vlan(4) doesn't seem to use csum_data and csum_flags in mbufs anyway.
