This brought in some additional config items that were hidden with
NUMA off. I have made best attempts, but let me know if you would like
any of these to change:
CONFIG_EMU_SIZE=0x10000000
CONFIG_NODES_SHIFT=4
CONFIG_NUMA_BALANCING_DEFAULT_ENABLED=y
CONFIG_NUMA_BALANCING=y
CONFIG_NUMA_EMU=y
CONFIG_NUMA=y
I've asked IBM for a review of the config options and here is the reply:
"The config option CONFIG_NUMA_BALANCING_DEFAULT_ENABLED should be
*disabled *.
Automatic balancing does not make sense for FAKE NUMA and just produces
overhead by moving around memory.
The rest looks good to me."
Please update the config accordingly.
