This fixes a link error in current upstream when:
CONFIG_PCI=y
# CONFIG_AMD_NB not set
LD .tmp_vmlinux1
arch/x86/pci/built-in.o: In function `early_fill_mp_bus_info':
/opt/src/linux/arch/x86/pci/amd_bus.c:189: undefined reference to
`amd_get_mmconfig_range'
make: *** [.tmp_vmlinux1] Error 1

Subject [PATCH] x86/PCI: build amd_bus.o only when CONFIG_AMD_NB=y
From Bjorn Helgaas <>
Date Thu, 12 Jan 2012 08:01:40 -0700
We only need amd_bus.o for AMD systems with PCI. arch/x86/pci/Makefile
already depends on CONFIG_PCI=y, so this patch just adds the dependency
on CONFIG_AMD_NB.
