PCI: add set_nouse_crs for use by a pci=nocrs blacklist
Some machines don't boot unless passed pci=nocrs. (See https://bugzilla.redhat.com/show_bug.cgi?id=770308 for details of one report. Waiting on dmidecode output for others). Currently there is a DMI whitelist, even though the default is on. v2: drop the 1536 blacklist entry, superceded by the PNP/MMCONFIG changes from Bjorn Acked-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
