[PATCH] Fix X86_GENERICARCH & NUMA compile error

[PATCH] Fix X86_GENERICARCH & NUMA compile error

From: Matthew Dobson <colpatch@us.ibm.com>

Trying to build a kernel with both CONFIG_X86_GENERICARCH and
CONFIG_NUMA on results in a compile error.  This patch fixes that build
problem by adding a config option for NUMA on Summit which is used to
correctly conditionally compile arch/i386/kernel/summit.c and properly
ifdef the function calls used in generic code.  Please apply.
