/usr/src/linux-3.17.4-2.g2d23787/crypto/sha512_generic.c

but module's only available for for sha512

    find /lib/modules/3.17.4-2.g2d23787-desktop* -type f -name *sha*generic*ko
        /lib/modules/3.17.4-2.g2d23787-desktop/kernel/crypto/sha512_generic.ko

checking kernel config

    grep -i sha /boot/config-3.17.4-2.g2d23787-desktop | grep -y crypto
        CONFIG_CRYPTO_SHA1=y
        CONFIG_CRYPTO_SHA1_SSSE3=m
        CONFIG_CRYPTO_SHA256_SSSE3=m
        CONFIG_CRYPTO_SHA512_SSSE3=m
        CONFIG_CRYPTO_SHA256=y
        CONFIG_CRYPTO_SHA512=m
        CONFIG_CRYPTO_DEV_PADLOCK_SHA=m

note {SHA1,SHA256}=y

iiuc, for 'generic' modules to be (a) available, and (b) usable -- if only,
atm, via manual insertion, that should be, instead

    CONFIG_CRYPTO_SHA1=m
    CONFIG_CRYPTO_SHA256=m
    CONFIG_CRYPTO_SHA512=m

no?

( switching to kernel component )
