ioremap is not intended to be used for that purpose. It may work for
some systems and fail on others. So you'll have to supply a new function
for that purpose which on some architectures may just be the same as
ioremap.

Then the answer is obvious, produce the hooks in the US, then publish
them in book form, post them to Finland and get some poor students to
scan them and OCR them for months and re-build them there ;)
It does seem MAD that the US govt. will restrict you from exporting
crypto that is freely available outside the US. Obviously they think
that a terrorist or drug lord is too dumb to go to www.pgpi.com to get
the same program they aren't allowed to get from www.pgp.com!

The people making those descisions mostly don't even know what encryption
means. They only know it is something dangerous and probably criminal that
could take away their power over people.
So, what about IMporting crypto? I mean, the kernel isn't actually
_produced_ in the USA, is it? Or where do the official releases come from,
geographically?

All too true...

Since Linus works in the USA (memory says for Transmeta in
California), and he's the one making the official releases, I'd
presume that's where the official releases come from...

You could contact the maintainer of the patch-int-<linux-version> patches.
Not sure who that is, the patches already implement cipe, crypto for
loopback fs mounting. A very nice patch, although it takes a while for the
international patches, to come out after a new linux kernel release.
FYI, the patches are at ftp.kerneli.org.

Sadly. There should be more technical people in politics.
(Why do I feel like I just said an oxymoron?)

Hm. That is a problem, yes.
Well, we still have kerneli.org :) only to make the major distributions
include it in their international versions, then crypto will become a lot
more popular (I suppose)...
