Acked-by: Tejun Heo <[EMAIL PROTECTED]> Yeap, the patch looks good. I got tunnel visioned while converting to iomap and mechanically mapped IO BAR access to iomap. Thanks for catching this. This is already fixed in #upstream while converting to new-init-model (the code is in ata_pci_init_native_host() and does about the same thing as your patch does), so I think this patch is only needed for -stable.
