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.
