Change Details

This change depends on D17416. The idea is to provide a workaround for anyone that's negatively impacted by NUMA being configured in GENERIC. Setting vm.ndomains=1 in the loader overrides the NUMA topology detection in srat.c.

Setting vm.ndomains=1 in the loader overrides the NUMA topology detection in srat.c. Disabling NUMA this way does not completely remove the overhead associated with this option. In particular, we will still go through the vm_domainset iterator code on every memory allocation.
