Documentation: document /sys/devices/system/cpu/

Hi Greg, Randy,

Not sure who actually maintains Documentation/ABI/; if it's not either of
y'all then please point me at the correct maintainer.

Anyhow, I was proposing some patches to enhance the NUMA sysfs interface:

	http://thread.gmane.org/gmane.linux.kernel.mm/40084/

I documented my changes, but David Rientjes suggested that I take this
as an opportunity to do a more thorough job, so here is an attempt at
doing so by documenting at least the files that I saw on my system. Maybe
there are more that I didn't configure in, but I think this series covers
a good amount.

One thing David suggested was following the sysfs hierarchy a bit more
strictly wrt to the file name in Documentation/ABI. I renamed one existing
file, and then stuck all the new stuff into the result.

I made the decision to keep the granularity at the top level sysfs
CPU interface rather than break out each subdirectory into a separate
file. If that's not ok or preferred, let me know and I can split it out
(but I hope to avoid having to do that).

I split out each group of files into a separate patch, with my best
guess at interested parties cc'ed. That way, they can each bike-shed
me individually. ;)

Thanks,
/ac
