[ Upstream commit 71c53e19226b0166ba387d3c590d0509f541a0a1 ]
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,

[ Upstream commit 35b4f4d4a725cf8f8c10649163cd12aed509b953 ]
The uvesafb fbdev driver uses memory management information that is not
available on ARCH=um, so don't allow this driver to be built on UML.
Prevents these build errors:
../drivers/video/fbdev/uvesafb.c: In function ‘uvesafb_vbe_init’:
