Subject: [PATCH v1 4/4] powerpc/mm: Move nohash specifics in subdirectory
 mm/nohash
To:     Benjamin Herrenschmidt <benh@kernel.crashing.org>,
        Paul Mackerras <paulus@samba.org>,
        Michael Ellerman <mpe@ellerman.id.au>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Many files in arch/powerpc/mm are only for nohash. This patch
creates a subdirectory for them.
