Your changelogs gives zero insight on this change. I used this for compile testing since I build on s390 natively and this would have hidden the missing HAS_IOPORT dependencies I'm pretty sure it was added because of the I/O port problem too. I'll either add to the commit description that it is no longer needed or drop this. Any preference?
