[PATCH] staging: Disable lustre file system for MIPS, SH, and XTENSA

[Guenter Roeck]

mips allmodconfig fails with

ERROR: "copy_from_user_page" [drivers/staging/lustre/lustre/libcfs/libcfs.ko]
undefined!

which is due to LUSTRE using copy_from_user_page which is not exported by any
architecture. Unfortunately, LUSTRE can only be built as module, so there is no
easy fix.

MIPS, SH, and optionally XTENSA implement copy_from_user_page as unexported
functions. Disable LUSTRE for those.
