o Removed hwmp_discover call from PREQ, because sending a PREP will

Break out the arge MDIO bus code into an optional argemdio device.
This is only done if the ARGE_MDIO option is included.
* Shuffle the arge MDIO bus into a separate device, that needs to be
probed early (use hint.argemdio.X.order=0)
* hint.arge.X.mdio now specifies which miiproxy to rendezvous with.
* Call MAC/MDIO bus init during MDIO attach, not arge attach.
This is done regardless:
* Shift the arge MAC and MDIO bus reset code into separate functions
and call it early during MDIO bus attach. It's required for
correct MDIO bus IO to occur on AR71xx/AR91xx devices.
* Remove the AR71xx/AR91xx centric assumption that there's only one
MDIO bus. The initial code mapped miibus0(arge0) and miibus1(arge1)
MII register operations to the MII0 (arge0) register space. The
AR724x (and later, upcoming chipsets) have two MDIO busses and
the second is very much in use.

MDIO/MII rendezvous proxy.
* Add an 'mdio' bus, which is the "IO" side of an MII bus (but by design
can be anything which implements the underlying register access API.)
* Add 'miiproxy' and 'mdioproxy', which provides a rendezvous mechanism

necessarily a traditional looking MII bus.)
MII busses can now hang off anything that implements an mdiobus.
For the AR71xx SoC, there's one MDIO bus but two MII busses. So to

no effect, since both header protections are equivalent. However the GNU version

Remove incorrect __restrict qualifier on several pointers
The typical case was:
static __inline int
convert_ccl(FILE *fp, char * __restrict p, [...])
{
[...]
if (p == SUPPRESS_PTR) {
[...]
} else {
[...]
}
[...]
}
This qualifier says that the pointer is the only one at that time
pointing to the resource.
Here, clang considers that "p" will never match "SUPPRESS_PTR" and
optimize the if{} block out. This leads to segfaults in programs calling
vfscanf(3) and vfwscanf(3) with just the format string (no arguments
following it).

Fix a bug in *wscanf's handling of non-wide %s, %c, and %[
conversions. Both the specification and the documentation say the
width is interpreted as the max number of wide characters to read, but
the implementation was interpreting it as the number of bytes to convert.
(See also r105317.)
This change has security implications for any applications that depend
on the buggy behavior, but the impact in practice is probably nil.
Any such application would already be buggy on other platforms that
get the semantics right. Also, these conversions are rarely used;
%ls, %lc, and %l[ are more appropriate.
Catch the user-error when no queue name was specified on an
lpc-command which supports '-msg' (e.g.: setstatus). Print
out a helpful error message instead hitting a seg-fault.

Previously, vfscanf()'s wide character processing functions were
reading wide characters manually. With this change, they now use
fgetwc(). To make this work, we use an internal version of fgetwc()
with a few extensions: it takes an mbstate * because non-wide streams
don't have a built-in mbstate, and it indicates the number of bytes
read.
vfscanf() now resembles vfwscanf() more closely. Minor functional
improvements include working xlocale support in vfscanf(), setting the
stream error indicator on encoding errors, and proper handling of
shift-based encodings. (Actually, making shift-based encodings work
with non-wide streams is hopeless, but the implementation now matches
the broken specification.)
