Use the new cache functions for invalidating single pages.
that td_intr_nesting_level is 0 (like malloc() does). Since malloc() calls
uma we can probably remove the check in malloc() for this now. Also,
perform an extra witness check in that case to make sure we don't hold
any locks when performing a M_WAITOK allocation.
yet. We just return without performing any checks.
- Don't explicitly enter and exit critical sections when walking lock
lists. We don't need a critical section to walk the list of sleep
locks for a thread. We check to see if a spin lock list is empty
before we walk it. If the list is empty we don't need to walk it. If
it isn't then we already hold at least one spin lock and are already in
a critical section and thus don't need our own explicit critical
section.
initialized socket with no qlimit was being passed in. In order
to handle this case properly, we must not use >= when comparing
queue sizes to qlimit. As a result of this improper handling,
a panic could result in certain cases.

o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
socket buffer. The mutex in the receive buffer also protects the data
in struct socket.
o Determine the lock strategy for each members in struct socket.
o Lock down the following members:
- so_count
- so_options
- so_linger
- so_state
o Remove *_locked() socket APIs. Make the following socket APIs
touching the members above now require a locked socket:
- sodisconnect()
- soisconnected()
- soisconnecting()
- soisdisconnected()
- soisdisconnecting()
- sofree()
- soref()
- sorele()
- sorwakeup()
- sotryfree()
- sowakeup()

fix a comment that suggested setting ipv6_ipv4mapping to blank. This
will aid in merging with rcng which requires all veriables to be
explicitly set.

make_dev() to create device nodes for each of the serial port channels
(ttym%d and cuam%d respectively, as borrowed from MAKEDEV). This allows
the rc driver to work in 5.0. I've tested it with only one card, but
will try sticking in a second card tomorrow and see what happens.

Change msU macros to mU.
This is only a partial solution; the whole issue of building the
documentation needs to be revisited.
