mips allmodconfig fails with

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.
Then why would it be a problem?
It isn't a problem for those other architectures. Mostly it is mapped to functions like memcpy().

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.
Sounds good to me, consider it forgotten :)
