Stack is not needed since implementation store blocks in registers. --- Jussi Kivilinna (5): crypto: x86/glue_helper - use le128 instead of u128 for CTR mode crypto: cast6/avx - avoid using temporary stack buffers crypto: twofish/avx - avoid using temporary stack buffers crypto: serpent/avx - avoid using temporary stack buffers crypto: cast5/avx - avoid using temporary stack buffers arch/x86/crypto/camellia_glue.c | 16 + arch/x86/crypto/cast5-avx-x86_64-asm_64.S | 332 +++++++++++++++++++++------ arch/x86/crypto/cast5_avx_glue.c | 79 ++---- arch/x86/crypto/cast6-avx-x86_64-asm_64.S | 190 ++++++++++----- arch/x86/crypto/cast6_avx_glue.c | 77 +----- arch/x86/crypto/glue_helper-asm-avx.S | 91 +++++++ arch/x86/crypto/glue_helper.c | 12 - arch/x86/crypto/serpent-avx-x86_64-asm_64.S | 166 +++++++++----- arch/x86/crypto/serpent_avx_glue.c | 49 +--- arch/x86/crypto/serpent_sse2_glue.c | 12 - arch/x86/crypto/twofish-avx-x86_64-asm_64.S | 208 +++++++++++------ arch/x86/crypto/twofish_avx_glue.c | 73 +----- arch/x86/crypto/twofish_glue_3way.c | 20 +- arch/x86/include/asm/crypto/glue_helper.h | 28 +- arch/x86/include/asm/crypto/serpent-avx.h | 27 +- arch/x86/include/asm/crypto/twofish.h | 4 16 files changed, 835 insertions(+), 549 deletions(-) create mode 100644 arch/x86/crypto/glue_helper-asm-avx.S
