ff7447dae1 MFp4: Make it work :-)
o Don't delay when checking the done bits.  There's no gain other
	  than a small performance hit.
	o calculate the clock divisors better (things are still way slow,
	  so maybe there's more here?)
	o don't always fail reset.  Always succeed instead.
	o fix inverted logic around at91_twi_wait() return value
	o remove debug code
	o remove unneeded, unworking junk

8cd5dc08c3 MFp4:
o Fix the packet statistics
	o Make sure we set the FD bit when in full duplex
	o Improve TX side efficency by eliminating a data copy for
	  unfragmented mbufs (the hardware can't do s/g).
	o Minor busdma pedantry
	o better comments in some places, more XXX in others
	o Minor style nits.

This solves a problem I was seeing where I'd get no ethernet when not
booting with a NFS root.  Well, unless I unplugged the cable and
plugged it back in first so I'd get the same up down up messages I get
for NFS root...

Thanks to sam and scottl for suggestions on making this driver more
efficient through better use of approrpiate APIs.

da834c5711 Do not include both <sys/types.h> and <sys/param.h>, it is a style bug as
sys/types.h is included in sys/param.h, so instead just move the
#include <sys/param.h> before the headers that need it.

3d068827c2 Add a cnputs() function to write a string to the console with
a lock to prevent interspersed strings written from different CPUs
at the same time.

To avoid putting a buffer on the stack or having to malloc one,
space is incorporated in the per-cpu structure. The buffer
size if 128 bytes; chosen because it's the next power of 2 size
up from 80 characters.

String writes to the console are buffered up the end of the line
or until the buffer fills. Then the buffer is flushed to all
console devices.

Existing low level console output via cnputc() is unaffected by
this change. ithread calls to log() are also unaffected to avoid
blocking those threads.

A minor change to the behaviour in a panic situation is that
console output will still be buffered, but won't be written to
a tty as before. This should prevent interspersed panic output
as a number of CPUs panic before we end up single threaded
running ddb.

3750d1ecad Remove the KSE option now that it's in DEFAULTS on these arches/machines.
The 'nooption' kernel config entry has to be used to turn KSE off now.
This isn't my preferred way of dealing with this, but I'll defer to
scottl's experience with the io/mem kernel option change and the grief
experienced over that.

06e28eec94 Ok I am an idiot. On 32 bits big-endian systems, it is needed to handle the
syscalls using __syscall but only actually returning 32bits, such as mmap(),
specially : they set the return value in td->td_retval[0], but the userland
functions will expect this in r1, and not in r0 as it is normally done, as it
is the LSB. So add a special case for all these syscalls (all except lseek,
which truly returns 64bits).

Many thanks to Peter Grehan for his patience while explaining me the issue.
