the page queues lock, which is already held, rather than Giant.

for the SYN|ACK packet and then letting in6_pcbconnect set the
flowlabel later. Arange for the syncache/syncookie code to set and
recall the flow label so that the flowlabel used for the SYN|ACK
is consistent. This is done by using some of the cookie (when tcp
cookies are enabeled) and by stashing the flowlabel in syncache.

served the same purpose) and use M_SKIP_FIREWALL in pf as well. This should
speed up things a bit as we get rid of the tag allocations.

using M_PROTO6 and possibly shooting someone's foot, as well as allowing the
firewall to be used in multiple passes, or with a packet classifier frontend,
that may need to explicitly allow a certain packet. Presently this is handled
in the ipfw_chk code as before, though I have run with it moved to upper
layers, and possibly it should apply to ipfilter and pf as well, though this
has not been investigated.

since they are only accessed by curthread and thus do not need any
locking.
- Move pr_addr and pr_ticks out of struct uprof (which is per-process)
and directly into struct thread as td_profil_addr and td_profil_ticks
as these variables are really per-thread. (They are used to defer an
addupc_intr() that was too "hard" until ast()).
define NULL. This means we cannot use NULL in the definition of CMSG_NXTHDR.
So replace NULL with 0.

it was an acpi child device, it really is a PCI device. Fix this by making
it a PCI child.
* Remove non-handle ivars accesses since child busses only implement
acpi_get_handle().
* Access the acpi softc directly through the devclass instead of through
the implied parent.
* Clean up a potential panic on unload by freeing the sysctl context before
storing NULL in the OID.

Device-dependent drivers, named after the sound module names.
Configure accordingly to your hardware.
In addition, rename the `snd_pcm' module to `sound' in order to sync

Biba and MLS labels. It also approximates the use of 'effective' in
traditional UNIX credentials, and avoids confusion with 'singlelabel'

We need the ttyopen() and ttyclose() for the new generic cdevsw
