Subject: [PATCH v2 2/2] powerpc/kexec: move kexec files into a dedicated
 subdir.

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

arch/powerpc/kernel/ contains 7 files dedicated to kexec.

Move them into a dedicated subdirectory.

Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

v2: moved crash.c as well as it's part of kexec suite.
