Subject: [PATCH 1/2] fbdev: geode: don't build on UML
The geode fbdev driver uses struct cpuinfo fields that are not present
on ARCH=um, so don't allow this driver to be built on UML.
Prevents these build errors:
In file included from ../arch/x86/include/asm/olpc.h:7:0,

Say 'Y' here to allow you to select framebuffer drivers for
the AMD Geode family of processors.
