Subject: [PATCH 2/2] Allow any x86 sub-architecture type to set CONFIG_NUMA


While there are a limited number of x86 sub-architecture types that can
really support NUMA, there is nothing stopping other machines booting that
type of kernel. The fact that X86_GENERICARCH can set NUMA currently is an
indicator of that. This restriction only limits potential testing coverage.
This patch allows any sub-architecture to set CONFIG_NUMA if they wish.
