Here's a dumb simple implementation of fake NUMA nodes for PowerPC.
Fake NUMA nodes can be specified using the following command line option
numa=fake=<node range>
node range is of the format <range1>,<range2>,...<rangeN>
Each of the rangeX parameters is passed using memparse(). I find this
useful for fake NUMA emulation on my simple PowerPC machine. I've
tested it on a non-numa box with the following arguments:
numa=fake=1G
numa=fake=1G,2G
name=fake=1G,512M,2G
numa=fake=1500M,2800M mem=3500M
numa=fake=1G mem=512M
numa=fake=1G mem=1G
