off of the file system root: "user" for user attributes, and "system"
for system attributes. When the scan occurs, attribute backing files
discovered in those directories will be started in the respective
namespaces. This re-introduces support for auto-starting of user
attributes, which was removed when the "$" prefix for system attributes
was replaced with explicit namespacing.
For users of the TrustedBSD UFS POSIX.1e ACL code, you'll need to:
mv ${FSROOT}/'$posix1e.acl_access' ${FSROOT}/system/posix1e.acl_access
mv ${FSROOT}/'$posix1e.acl_default' ${FSROOT}/system/posix1e.acl_default
For users of the TrustedBSD POSIX.1e Capability code, you'll need to:
mv ${FSROOT}/'$posix1e.cap' ${FSROOT}/system/posix1e.cap
For users of the TrustedBSD MAC code, you'll need to:
mv ${FSROOT}/'$freebsd.mac' ${FSROOT}/system/freebsd.mac
Updated versions of relevant patches will be released in the near
future.

- Make sure that m_mballoc() really doesn't allow over nmbufs mbufs to
be allocated from mb_map. In the case where nmbufs-reserved space is not
an exact multiple of PAGE_SIZE (which it should be, but anyway...), we
hold nmbufs as an absolute maximum which need not ever be reached.
- Clean up m_clalloc(); make it more consistent in the sense that the first
argument `ncl' really means "the number of clusters ensured to be allocated"
and not "the number of pages worth of clusters to be allocated," as was
previously the case. This also makes it consistent with m_mballoc() as well
as the comment that preceeds it.

Make the name cache hash as well as the nfsnode hash use it.
As a special tweak, create an unsigned version of register_t. This allows
us to use a special tweak for the 64 bit versions that significantly
speeds up the i386 version (ie: int64 XOR int64 is slower than int64
XOR int32).
The code layout is a little strange for the string function, but I was
able to get between 5 to 10% improvement over the original version I
started with. The layout affects gcc code generation choices and this way
was fastest on x86 and alpha.
Note that 'CPUTYPE=p3' etc makes a fair difference to this. It is
around 45% faster with -march=pentiumpro on a p6 cpu.
Fowler / Noll / Vo Hash (http://www.isthe.com/chongo/tech/comp/fnv/).
This improves hash coverage a *massive* amount. We were seeing one
set of machines that were using 0.84% of their 131072 entry nfsnode
hash buckets with maximum chain lengths of up to ~500 entries. The
machine was spending nearly 100% of its time in 'system'.
A test with this has pushed the coverage from a few perCent up to 91%
utilization with a max chain length of 11.

Add the AAC_DEBUG option to enable debugging in the aac driver.
Correct a race condition in the interrupt handler where the
controller may queue a fib to a response queue after the driver
has serviced the queue but before the interrupt is cleared.
This could leave a completed fib stranded in the response queue
unless another I/O completed and generated another interrupt.

the socket buffer size, the receive is done in sections. After completing
a read, call pru_rcvd on the underlying protocol before blocking again.
This allows the the protocol to take appropriate action, such as
sending a TCP window update to the peer, if the window happened to
close because the socket buffer was filled. If the protocol is not
notified, a TCP transfer may stall until the remote end sends a window
probe.

So we now get the length from the inquiry data returned by the drive.
(Since we will fetch as much inquiry data as the drive claims to support.)
