[PATCH] [x86] NUMA implied when DISCONTIGMEM

[Christoph Egger]

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we are looking at multiple integrity errors in linux'
configuration system.

	x86 Kconfig implies NUMA if DISCONTIGMEM is selected (the
dependency is as [1] -- excerpt from our tool's output) meaning a
check for NUMA inside a DISCONTIGMEM is useless (in x86 specific code
not in general), so this part can be simplified as in the below patch.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger
