commit 2863d5f3cd96d66cadeef19b8b4111de55ce78de
Author: Andy Polyakov <appro at openssl.org>
Date:   Fri Jan 23 18:02:44 2015 +0100

    des/asm/des_enc.m4: strip #ifdef OPENSSL_SYS_ULTRASPARC as part of
    pre-processor controls cleanup. It doesn't mean that it no longer
    works on UltraSPARC, only that it doesn't utilize sparcv9-specific
    features like branch prediction hints and load in little-endian byte
    order anymore. This "costs" ~3% in EDE3 performance regression on
    UltraSPARC.
