From d8cb4e119f9a97f87f69a179d855f5dfc5d578c2 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sun, 11 Jun 2006 23:03:08 +0100 Subject: [PATCH] [MIPS] Cleanup ARCH_DISCONTIGMEM_ENABLE and NUMA configuration. IP27 configuration isn't the only NUMA system - it just happens to be the currently only supported MIPS NUMA system. So move the necessary options back into the main MIPS Kconfig file.
