From c77b8912d86a08b57bab21982a865fbf2151f0af Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 22 Jul 2015 01:21:12 -0700 Subject: [PATCH] x86: Allow cpu-x86 driver to be probed for UP Currently cpu-x86 driver is probed only for SMP. We add the same support for UP when there is only one cpu node in the deive tree.
