FWIW, I've traced the use of inb_p and outb_p to access the PIT timer
all the way back to Linux 0.10

I wonder if any of the systems affected actually has enough memory to boot
a modern kernel or if the _p versions have become useless bagagge that
should be dropped - cleanup which would then also allow more code to the
iomap() API.

I'm interested because quite a few MIPS systems have been built based on
Intel, OPTi and other chipsets which may or may not have been affected.
