crypto: vmx - Move to arch/powerpc/crypto

Relocate all crypto files in vmx driver to arch/powerpc/crypto directory and remove vmx directory. drivers/crypto/vmx/aes.c rename to arch/powerpc/crypto/aes.c drivers/crypto/vmx/aes_cbc.c rename to arch/powerpc/crypto/aes_cbc.c drivers/crypto/vmx/aes_ctr.c rename to arch/powerpc/crypto/aes_ctr.c drivers/crypto/vmx/aes_xts.c rename to arch/powerpc/crypto/aes_xts.c drivers/crypto/vmx/aesp8-ppc.h rename to arch/powerpc/crypto/aesp8-ppc.h drivers/crypto/vmx/aesp8-ppc.pl rename to arch/powerpc/crypto/aesp8-ppc.pl drivers/crypto/vmx/ghash.c rename to arch/powerpc/crypto/ghash.c drivers/crypto/vmx/ghashp8-ppc.pl rename to arch/powerpc/crypto/ghashp8-ppc.pl drivers/crypto/vmx/vmx.c rename to arch/powerpc/crypto/vmx.c deleted files: drivers/crypto/vmx/Makefile drivers/crypto/vmx/Kconfig drivers/crypto/vmx/ppc-xlate.pl This patch has been tested has passed the selftest. The patch is also tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled. Signed-off-by: Danny Tsen <dtsen@linux.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
