The patchset contains mainly scalability and NUMA stuff, and anything
else that stops things from irritating me. It's meant to be pretty stable,
not so much a testing ground for new stuff.
I'd be very interested in feedback from anyone willing to test on any
platform, however large or small.

Since 2.5.72-mjb1 (~ = changed, + = added, - = dropped)
Notes: I applied lots of patches which affect similar areas. They all went on
without any problems. That's a worse omen than waking up in a pentagram
full of black candles ... chances I haven't managed to screw something up are
minimal. Go ahead, break it. Make my day.

Add a tag to the makefile
During build:
include/linux/mm.h: In function `page_to_nid':
include/linux/mm.h:620: warning: implicit declaration of function `pfn_to_nid'
This patch shuts it up, but I'm only guessing as to whether
page_to_nid is NUMA-specific.
