PCI: Add ability to mmap legacy_io on some platforms
This adds the ability to mmap legacy IO space to the legacy_io files in sysfs on platforms that support it. This will allow to clean up X to use this instead of /dev/mem for legacy IO accesses such as those performed by Int10. While at it I moved pci_create/remove_legacy_files() to pci-sysfs.c where I think they belong, thus making more things statis in there and cleaned up some spurrious prototypes in the ia64 pci.h file Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
