Correct a very old and very obscure bug: vmspace_fork() calls
pmap_copy() if the mapping is VM_INHERIT_SHARE. Suppose the mapping
is also wired. vmspace_fork() clears the wiring attributes in the vm
map entry but pmap_copy() copies the PG_W attribute in the PTE. I
don't think this is catastrophic. It blocks pmap_remove_pages() from
destroying the mapping and corrupts the pmap's wiring count.
This revision fixes the problem by changing pmap_copy() to clear the
PG_W attribute.

arguments. For now, this is a work-around only, as sparc64 remains
broken for these ioctls, but it makes keyboard ioctls for little
endian LP64 platforms such as amd64 work again when using kbdmux
(it is used in the GENERIC kernel). A one true fix for all is in
works, and will be committed to -CURRENT shortly.

Sleep for one second after calling audit -t to give the audit daemon a
chance to actually terminate the audit service and exit. Otherwise, on
an rc.d/auditd restart, the new audit daemon instance may try to start
auditing while the previous session is still running. Likewise, this
ensures a chance for auditd to terminate the audit trail at system
shutdown.
Perhaps more ideally, the script would wait synchronously for auditd to
exit rather than for an arbitrary but short period of time.

Rework the way errors are handled with respect to how audit records are
written to the audit trail file:
- audit_record_write() now returns void, and all file system specific
error handling occurs inside this function. This pushes error handling
complexity out of the record demux routine that hands off to both the
trail and audit pipes, and makes trail behavior more consistent with
pipes as a record destination.
- Rate limit kernel printfs associated with running low on space. Rate
limit audit triggers for low space. Rate limit printfs for fail stop
events. Rate limit audit worker write error printfs.
- Document in detail the types of limits and space checks we perform, and
combine common cases.
This improves the audit subsystems tolerance to low space conditions by
avoiding toasting the console with printfs are waking up the audit daemon
continuously.

The sparc64/sparc64/pmap.c implementations of pmap_remove(),
pmap_protect(), and pmap_copy() have optimizations for regions
larger than PMAP_TSB_THRESH (which works out to 16MB). This
caused a panic in tsb_foreach for kernel mappings, since
pm->pm_tsb is NULL in that case. This fix teaches tsb_foreach
to use the kernel's tsb in that case.

pccard_ether rev 1.51:
Search the list of up interfaces provided by "ifconfig -ul" instead of
greping for UP in "ifconfig $ifn". This eliminates a dependancy on /usr.
pccard_ether rev 1.53 and network.subr rev 1.173:
Introduce a new method ipv6if which attemptes to figure out if an
interface is an IPv6 interface.
Use this method to decide if we should attempt to configure an interface
with an IPv6 address in pccard_ether. The mechanism pccard_ether uses
to do this is unsuited to the task because it assumes the list of
interfaces it is passed is the full list of IPv6 interfaces and makes
decissions based on that. This is at least a step in the right
direction and is probably about as much as we can MFC safely.

a short transfer that transferred 0 bytes of the requested qTD
transfer size does cause a toggle change, but the existing code was
