*	crypto: s390 - add crypto library interface for ChaCha20	Vladis Dronov	2022-05-13	3	-0/+418
	Implement a crypto library interface for the s390-native ChaCha20 cipher algorithm. This allows us to stop to select CRYPTO_CHACHA20 and instead select CRYPTO_ARCH_HAVE_LIB_CHACHA. This allows BIG_KEYS=y not to build a whole ChaCha20 crypto infrastructure as a built-in, but build a smaller CRYPTO_LIB_CHACHA instead. Make CRYPTO_CHACHA_S390 config entry to look like similar ones on other architectures. Remove CRYPTO_ALGAPI select as anyway it is selected by CRYPTO_SKCIPHER. Add a new test module and a test script for ChaCha20 cipher and its interfaces. Here are test results on an idle z15 machine: Data \| Generic crypto TFM \| s390 crypto TFM \| s390 lib size \| enc dec \| enc dec \| enc dec -----+--------------------+------------------+---------------- 512b \| 1545ns 1295ns \| 604ns 446ns \| 430ns 407ns 4k \| 9536ns 9463ns \| 2329ns 2174ns \| 2170ns 2154ns 64k \| 149.6us 149.3us \| 34.4us 34.5us \| 33.9us 33.1us 6M \| 23.61ms 23.11ms \| 4223us 4160us \| 3951us 4008us 60M \| 143.9ms 143.9ms \| 33.5ms 33.2ms \| 32.2ms 32.1ms Signed-off-by: Vladis Dronov <vdronov@redhat.com> Reviewed-by: Harald Freudenberger <freude@linux.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
