PCI: Don't reassign resources that are already aligned The "pci=resource_alignment=" kernel argument designates devices for which we want alignment greater than is required by the PCI specs. Previously we set IORESOURCE_UNSET for every MEM resource of those devices, even if the resource was *already* sufficiently aligned. If a resource is already sufficiently aligned, leave it alone and don't try to reassign it. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
