Subject: [PATCH v1 2/4] powerpc/mm: Move book3s64 specifics in subdirectory
 mm/book3s64
To:     Benjamin Herrenschmidt <benh@kernel.crashing.org>,
        Paul Mackerras <paulus@samba.org>,
        Michael Ellerman <mpe@ellerman.id.au>
Cc:     linux-kernel@vger.kernel.org, linuxppc-dev@lists.ozlabs.org
Date:   Fri, 29 Mar 2019 10:00:00 +0000 (UTC)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Many files in arch/powerpc/mm are only for book3S64. This patch
creates a subdirectory for them.
