Subject: [PATCH 20/24] net, diet: Make XPS configurable

From: Andi Kleen <ak@...ux.intel.com>

Not needed on small systems. Already disabled with !SMP,
but also makes sense to explicitely disabled on very
small multi-core SOCKs.

Saves ~6k text, but increases the data segment by a
mysterious ~4k (some padding?)

   text	   data	    bss	    dec	    hex	filename
6893698	1392544	 634880	8921122	 882022	vmlinux-with-xps
6887542	1396544	 634880	8918966	 8817b6	vmlinux-wo-xps
