[PATCH 3/4] IB/qib: Compile under User-Mode Linux

From: David Gow
Date: Fri Feb 18 2022 - 02:58:19 EST


The User-Mode-Linux architecture (with the x86_64 subarch) defines
CONFIG_X86_64, but doesn't expose the cpuinfo_x86 struct (instead
there's a cpuinfo_um struct).

In order to allow UML to build with allyesconfig, only check cpuinfo_x86
on non-UML architectures.
