how they work in 4-STABLE.

always set to DEV_BSIZE, since the size of the directories is not
currently kept.

For an object type, we maintain a variable mb_mapfull. It is 0 by default
and is only raised to 1 in one place: when an mb_pop_cont() fails for
the first time, on the assumption that the reason for the failure is
due to the underlying map for the object (e.g. clust_map, mbuf_map) being
exhausted.
Problem and Changes:
Change how we define "mb_mapfull." It now means: "set to 1 when the first
mb_pop_cont() fails only in the kmem_malloc()-ing of the object, and
only if the call was with the M_TRYWAIT flag." This is a more conservative
definition and should avoid odd [but theoretically possible] situations
from occuring. i.e. we had set mb_mapfull to 1 thinking the map for the
object was actually exhausted when we _actually_ failed in malloc()ing
the space for the bucket structure managing the objects in the page
we're allocating.

yamamoto-san's original patch had a small race window for AX88190
chips, which I corrected by limiting the number of iterations we'd try
to reset the bits to be about 15ms rather than forever. This seems to
work for me, but I don't have a large collections of cards based on
this chipset.

snooped on. This causes all kinds of Bad Things(tm) to happen since
closing one session will clobber state that's needed for the other
one. This could theoretically be supported if the code was careful,
but until somebody implements that, preventing this will stop people
from unknowingly shooting themselves in the foot.
device cloned, and assign all further devices to depend on it. This
allows us to call dev_depends() on it at module unload time to get rid
of /dev/snp* (in the devfs case, anyway). For this to work, we must
not destroy the device at close time. [Idea stolen from if_tun.]
The above has the following sideaffects: (a) The snp device used by
watch(8) will remain after watch(8) exits. This is probably how it
should have been all along, and how it was before devfs came along.
(b) Module unload doesn't panic if there are any /dev/snp* devices
which haven't been used (and thus previously destroyed). Thus, we can
reenable the unload functionality disabled in rev. 1.65.

- Add memory barrier definition for sparc64.
Patch sent by David E. O'Brien, approved by maintainer.
- Fix an endianization error of a bus physical address used from SCRIPTS
that made the driver fail on big endian machines as sparc64.
The kernel certainly doesn't use _PATH_DEV or even /dev/ to find the device.
It cannot, since "/" has not been mounted. Maybe the only affect of using
/dev/ is that it gets put in the mounted-from name for "/", so that mount(8),
etc., display an absolute path before "/" has been remounted. Many have
never bothered typing the full path, and code that constructs a path in
rootdevnames[] never bothered to construct a full path, so the example
shouldn't have it.

device. Add a new quirk to cover this case, and enable it for C-1
cameras. The quirk enables translation from the C-1 signature to
the normal CSWSIGNATURE value.

Actually this porting supports Pegasus II chip so I guess some other
devices supported by NetBSD also work. But the devices list are not
included because I cannot confirm if they work.
