Okay. So for regular ISA port io drivers, I should just the regular kernel
intrinsics then, eh? Fine.
Just wanted to make sure I wasn't missing anything...
(Dave, did you receive the other mail I sent to you directly?)

Subject: Re: [Linux-streams] osif.h and port io?
LiS stands for Linux STREAMS. As such it only attempts to provide kernel
interface buffering for services needed by STREAMS drivers. These services
do
not include copy_from/to_user.
The port I/O routines would be good to add, though.
