Commit: 0bbf47eab469 ("ia64: use asm-generic/io.h")
results in a BUG while booting ia64. This is because asm-generic/io.h defines PCI_IOBASE, which results in the function acpi_pci_root_remap_iospace() doing a lot of unnecessary (and wrong) things.
I'd suggested an #if !CONFIG_IA64 in the functon, but Arnd suggested keeping the fix inside the arch/ia64 tree.
