    crypto: arm64/crc32 - remove PMULL based CRC32 driver · 598b7d41

    Now that the scalar fallbacks have been moved out of this driver into
    the core crc32()/crc32c() routines, we are left with a CRC32 crypto API
    driver for arm64 that is based only on 64x64 polynomial multiplication,
    which is an optional instruction in the ARMv8 architecture, and is less
    and less likely to be available on cores that do not also implement the
    CRC32 instructions, given that those are mandatory in the architecture
    as of ARMv8.1.
    
    Since the scalar instructions do not require the special handling that
    SIMD instructions do, and since they turn out to be considerably faster
    on some cores (Cortex-A53) as well, there is really no point in keeping
    this code around so let's just remove it.
