Previously I sent this as a treewide series titled "treewide: Remove I/O port accessors for HAS_IOPORT=n" with the latest being its 5th version[0]. With a significant subset of patches merged I've changed over to per-subsystem series. These series are stand alone and should be merged via the relevant tree such that with all subsystems complete we can follow this up with the final patch that will make the I/O port accessors compile-time optional. The current state of the full series with changes to the remaining subsystems and the aforementioned final patch can be found for your convenience on my git.kernel.org tree in the has_ioport branch[1]. As for compile-time vs runtime see Linus' reply to my first attempt[2]. The patch was previously acked[3] by Greg but given this was almost a year ago and didn't apply then I didn't carry the Ack over. That said I don't think there were non trivial changes.
