For non hotplug PCI devices, the system firmware usually configures CLS correctly. For pccard devices system firmware can't do it and Linux PCI layer doesn't do it either. Unfortunately this leads to poor performance for certain devices (sata_sil). Unless MWI, which requires separate configuration, is to be used, CLS doesn't affect correctness, so the configuration should be harmless. This patch makes pci_set_cacheline_size() always built and export it and make pccard call it during attach. Please note that some other PCI hotplug drivers (shpchp and pciehp) also configure CLS on hotplug.
