PCI: X86: Introduce and enable PCI domain support
* fix bug in pci_read() and pci_write() which prevented PCI domain support from working (hardcoded domain 0). * unconditionally enable CONFIG_PCI_DOMAINS * implement pci_domain_nr() and pci_proc_domain(), as required of all arches when CONFIG_PCI_DOMAINS is enabled. * store domain in struct pci_sysdata, as assigned by ACPI * support "pci=nodomains" Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
