x86, soc: Fix fallout from the previous changes
PATCH 1/1 x86, soc: Fix fallout from the previous changes
From: Alan Cox <[email protected]>
The PCI fixups get executed based upon whether they are linked in. We need to avoid executing them if we boot a dual SoC/PC type kernel on a PC class system.

This would be for Jesse's PCI tree I think.
Thanks,
