Very much to my surprise Fuxin Zhang reports this is all it takes to get
the kernel to work for page sizes larger than 4kB.  This also paves the
way for support for the R6000 and R8000 which don't support 4kB page size.

I'm pretty sure that the CKSEG0 bits are wrong, but I did need to
cover that region - because the SB-1 kernel links at 0xffffffff80100000
or so, disassembly and printing static variables don't work unless the
debugger can read that region.

In ip22-setup.c the checks for serial/graphics console logic does
not check if ARCS console=g but the machine is using serial console, as
it does if no keyboard is attached.
    
This patch adds a check if ConsoleOut is serial. There might also be
support for other graphics than Newport soon...

It looks glibc's pow() assumes an unary '-' operation for any number
(including NaNs) always inverts its sign bit (though IEEE754 does not
specify the sign bit for NaNs).  This patch make the kernel math-emu

Adding -mmad is not usable since over half a decade in gcc and when
fixed the proper -march option values should enable the use of the
mad, madu and mul instructions of the R5500, RM5200, RM7000 and RM9000
families.

Fix a really old buglet in AMD Au1xx0 restart code: instead of
modifying the whole CP0 Config.K0 field to 010b (meaning KSEG0 uncached)
before flushing the caches and resetting a board, it only sets bit 1 of that
reg. which is effectively a NOP since Config.K0 == 011b as the kernel sets it
up (which is also its default value for Au1xx0).

When we pull the PPP protocol off the skb, we forgot to update the
hardware RX checksum.  This may lead to messages such as

	dsl0: hw csum failure.

Similarly, we need to clear the hardware checksum flag when we use
the existing packet to store the decompressed result.
