This is insufficient - pci-bridge-emul.h needs to be fixed up to use __le32 and __le16. It is a good idea to check such changes with sparse - a tool originally written by Linus, which is able to detect incorrect endian accesses (iow, access to LE members without using a LE accessor.) Such checks rely on using the right types. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
