Revision: linuxbios@linuxbios.org--devel/freebios--devel--2.0--patch-3
Creator: Eric Biederman <ebiederman@lnxi.com>
Add read[bwl] write[bwl] to arch/io.h for i386
A pending patch requires needs this and ppc already has them
so it is a good idea to implement them :)
I don't know why this was not implemented earlier.
