BTW, I get the opposite results from François on my Debian system when I build all three crc32c drivers as modules:
jim@anima:/lib/modules/4.14.36-test2$ find . -name "*crc32c*"
./kernel/lib/libcrc32c.ko ./kernel/arch/x86/crypto/crc32c-intel.ko ./kernel/crypto/crc32c_generic.ko
crc32c_generic and crc32c_intel are added to the initrd, but libcrc32c is not.
lsinitramfs /boot/initrd.img-4.14.36-test2|grep crc32
lib/modules/4.14.36-test2/kernel/arch/x86/crypto/crc32c-intel.ko lib/modules/4.14.36-test2/kernel/crypto/crc32c_generic.ko

François, James,
Does this fix things for you?
Thanks,
