#     crypto: memneq - move into lib/
#     
#     This is used by code that doesn't need CONFIG_CRYPTO, so move this into
#     lib/ with a Kconfig option so that it can be selected by whatever needs
#     it.
#     
#     This fixes a linker error Zheng pointed out when
#     CRYPTO_MANAGER_DISABLE_TESTS!=y and CRYPTO=m:
#     
#       lib/crypto/curve25519-selftest.o: In function `curve25519_selftest':
#       curve25519-selftest.c:(.init.text+0x60): undefined reference to `__crypto_memneq'
#       curve25519-selftest.c:(.init.text+0xec): undefined reference to `__crypto_memneq'
#       curve25519-selftest.c:(.init.text+0x114): undefined reference to `__crypto_memneq'
#       curve25519-selftest.c:(.init.text+0x154): undefined reference to `__crypto_memneq'
