I think this should probably be

diff --git a/arch/parisc/Kconfig b/arch/parisc/Kconfig
--- a/arch/parisc/Kconfig
+++ b/arch/parisc/Kconfig
@@ -244,6 +244,9 @@ config ARCH_DISCONTIGMEM_DEFAULT

+config NUMA
+ def_bool ARCH_DISCONTIGMEM_ENABLE

default "3"
instead since we don't need CONFIG_NUMA for anything other than
CONFIG_PA8X00 and 64-bit enabled.
