Patch from Nicolas Pitre Here's an ARM assembly SHA1 implementation to replace the default C version. It is approximately 50% faster than the generic C version. On an XScale processor running at 400MHz: generic C version: 9.8 MB/s my version: 14.5 MB/s This code is useful to quite a few callers in the tree: crypto/sha1.c: sha_transform(sctx->state, sctx->buffer, temp); crypto/sha1.c: sha_transform(sctx->state, &data[i], temp); drivers/char/random.c: sha_transform(buf, (__u8 *)r->pool+i, buf + 5); drivers/char/random.c: sha_transform(buf, (__u8 *)data, buf + 5); net/ipv4/syncookies.c: sha_transform(tmp + 16, (__u8 *)tmp, tmp + 16 + 5); Signed-off-by: Nicolas Pitre <nico@cam.org> Seems to work fine on big-endian as well.
