I got sidetracked working on other things, but I did manage to
learn this so far - It turns out that Randy fixed it and then
James un-fixed it in this commit:

commit 97a29d59fc222b36bac3ee3a8ae994f65bf7ffdf
Author: James Bottomley <James.Bottomley@...senPartnership.com>
Date:   Mon Jan 30 10:40:47 2012 -0600

    [PARISC] fix compile break caused by iomap: make IOPORT/PCI mapping functions conditional

Reverting the above and mips builds 3c59x just fine.  Note that MIPS
allmodconfig does not have either CONFIG_GENERIC_IOMAP or the other
CONFIG_GENERIC_PCI_IOMAP options.

Paul.
