which is due to LUSTRE using copy_from_user_page which is not exported by any
architecture.

Any, or just these arches?

Other architectures implement it as define as far as I can see.

Unfortunately, LUSTRE can only be built as module, so there is no
easy fix.

Can't we just export the functions for those arches? Surely lutre
isn't the first/only driver that needs this?

That would be another option.

Actually, turns out Geert submitted a patch to do this for mips already, and Ralf applied it:

https://lkml.org/lkml/2013/9/5/111

So please forget this patch. If sh/xtensa actually need it, we can do the same there.
