local rc.d scripts in the overall boot order was added.
Proper rc.d scripts are run by rc.subr in a subshell, whereas scripts that
end in .sh are sourced into rc's shell. The latter has potential to create
serious boot problems, and there is no reason that the same functionality
cannot be added by the user in the form of a proper rc.d script (as
opposed to being added by the user in the form of /etc/rc.early).
This script will be removed prior to the 8.0 branch.

fixes a bug on UP machines with SMP kernels where the idle thread
constantly switches after trying to steal work from the local cpu.
- Make the idle stealing code more robust against self selection.
- Prefer to steal from the cpu with the highest load that has at least one
transferable thread. Before we selected the cpu with the highest
transferable count which excludes bound threads.

a consequence of sparc64/sparc64/vm_machdep.c revision 1.76. It occurs
when uma_small_free() frees a page. The solution has two parts: (1) Mark
pages allocated with VM_ALLOC_NOOBJ as PG_UNMANAGED. (2) Defer the lock
assertion in pmap_page_is_mapped() until after PG_UNMANAGED is tested.
This is safe because both PG_UNMANAGED and PG_FICTITIOUS are immutable
flags, i.e., they do not change state between the time that a page is
allocated and freed.

not being independently freeable. This allows one to embed an mbuf in
the cluster itself. This confers the benefits of the packet zone on
all cluster sizes. Embedded mbufs currently suffer from the same
limitation that packet zone mbufs do in that one cannot disconnect
them and pass them around independently of the cluster. It would
likely be possible to eliminate this limitation in the future by
adding a second reference for the mbuf itself.

with all functions supported. This is done adding usb device IDs
to the table of recognised devices (because there is no standard
'scanner' class, so no other way to recognise them), and with
a small change to the uscanner attach routine that prevents
reconfiguring the whole USB device while we are dealing only with
one of its USB interfaces.
The latter part has been suggested by Steinar Hamre in
http://www.freebsd.org/cgi/query-pr.cgi?pr=107665 , i have
only added a bit of explaination to the code.
I have personally tried this on the Epson DX-5050 and DX-6000
devices (on the US market they have different names, CX-something).
I have good reasons to think that, possibly with the mere addition
of more USB ids to the table in uscanner.c, this should work with
all Epson multifunction devices in that family (from DX-3800 to
DX-7000 - these units are in the 50-120$ price range).

with identical meaning as the colon ":". This is to support a syntax
that is more similar to a PCI device specification in the device hints
file. The selector is not fully compatible with the specification in
the hints file, since entries in that file use a different prefix,
which needs to be added to the getsel() routine, if full support of
that syntax is found to be desirable.

PCI selectors with 2 or 3 elements behave exactly as before (i.e. the
domain is 0 and in the 2 element case, the function is also 0).
The form with 4 selector elements works as in the previous revision
and provides the PCI domain number as the left-most selector element.
This change allows old scripts (which used the 2 or 3 selector element
formats) to be kept. Without this patch, the 3 element form was parsed
as starting with a domain number (and the function was assumed to be 0),
with this patch, the domain is assumed to be 0 (and the last value is
used as the function number).
The man page is updated to describe the new selector semantics.
