[CRYPTO] Add faster DES code from Dag Arne Osvik
I've made a new implementation of DES to replace the old one in the kernel. It provides faster encryption on all tested processors apart from the original Pentium, and key setup is many times faster. Speed relative to old kernel implementation Processor des_setkey des_encrypt des3_ede_setkey des3_ede_encrypt Pentium 120Mhz 6.8 0.82 7.2 0.86 Pentium III 1.266Ghz 5.6 1.19 5.8 1.34 Pentium M 1.3Ghz 5.7 1.15 6.0 1.31 Pentium 4 2.266Ghz 5.8 1.24 6.0 1.40 Pentium 4E 3Ghz 5.4 1.27 5.5 1.48 StrongARM 1110 206Mhz 4.3 1.03 4.4 1.14 Athlon XP 2Ghz 7.8 1.44 8.1 1.61 Athlon 64 2Ghz 7.8 1.34 8.3 1.49 Signed-off-by: Dag Arne Osvik <da@osvik.no> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
