Hi Andi, This is a follow up in my ongoing effort of making inb()/outb() and similar I/O port accessors compile-time optional. 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_v6 branch[1] with signed tags. As for compile-time vs runtime see Linus' reply to my first attempt[2].
