camellia_setup_tail() applies 'inverse of the last half of P-function' to subkeys, which is unneeded if keys are applied directly to yl/yr in CAMELLIA_ROUNDSM. Patch speeds up key setup and should speed up CAMELLIA_ROUNDSM as applying key to yl/yr early has less register dependencies. Quick tcrypt camellia results: x86_64, AMD Phenom II, ~5% faster x86_64, Intel Core 2, ~0.5% faster i386, Intel Atom N270, ~1% faster Signed-off-by: Jussi Kivilinna <redacted>
