[PATCH] PCI: fix build errors with CONFIG_PCI=n

["Randy.Dunlap" <rddunlap@osdl.org>]

[-- Attachment #1: Type: text/plain, Size: 992 bytes --]


Fix (most of) kernel build for CONFIG_PCI=n.  Fixes these 3 errors:

1. drivers/parport/parport_pc.c:3162: error: `parport_init_mode'
undeclared (first use in this function)

2. arch/x86_64/kernel/built-in.o(.text+0x8186): In function
`quirk_intel_irqbalance':
: undefined reference to `raw_pci_ops'

Kconfig change:
3. arch/x86_64/kernel/pci-gart.c:194: error: `pci_bus_type' undeclared
(first use in this function)

Still does not fix these 2 (similar):
a.  drivers/built-in.o(.text+0x3dcd8): In function
`pnpacpi_allocated_resource':
: undefined reference to `pcibios_penalize_isa_irq'
b.  drivers/built-in.o(.text+0xb4d4): In function
`pnpbios_parse_allocated_irqresource':
: undefined reference to `pcibios_penalize_isa_irq'
