Thanks!

Hmm.. I think it'll be simpler to just include asm/io.h to all
hostap_{cs,plx,pci} modules whether it is really needed or not. There
should not be any need to limit this to 2.6.x either.

I would assume hostap_cs.c ended up including this file either because I
needed it at some point for one of my target platforms that do not have
PCI bus.. Alternatively, it may have something to do with external
pcmcia-cs compilation.

I'm assuming you mean using kernel Makefile or not with
in/out-of-kernel.. I believe I have cross-compiled it
out-of-tree many times. However, nowadays I use kernel Makefiles for all
builds, so I wouldn't be too surprised if the Host AP makefile would not
handle something properly. If you meant linked-in-kernel without using
modules, then you can of course ignore this part ;-).
