Alan, Martin, Linus, and anyone else who cares, ;)
Here's a patch Martin and I put together a while ago to clean up the
xquad_portio kludgery that's been floating around for too long. I think
this pretty much goes along with what you have in your tree, Alan. It's
a small patch, so if no one complains, please apply Linus.
Cheers!

STANDALONE seems to be a very namespace-polluting choice of define.
MULTIQUAD_STANDALONE, MQ_STANDALONE... anything would be better imo.

The #define is most definitely *not* NUMA/Multiquad specific. In this
particular instance, it is guarding Multiquad specific code... The
STANDALONE option (please clarify if I'm wrong, Alan) is for code that
is compiled along with the kernel, with the kernel headers, etc, but is
not acually part of the kernel proper.
Cheers!

Indeed
Its set by the boot loader code that wants to also use inb/outb etc but
not get the kernel magic wonders of numa-q and other evil abuses of PC
iomapping

Linus,
I believe Alan cleared up the only objection to this small patch. Please
apply.
Changelog:
Cleans up a bit of a hack to get compressed (gziped) kernels booting on
NUMA-Q. Resulting code is more readable and understandable.
Cheers!
