Hi Herbert, After merging the crypto tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "crypto_fpu_exit" [arch/x86/crypto/aesni-intel.ko] undefined! ERROR: "crypto_fpu_init" [arch/x86/crypto/aesni-intel.ko] undefined! Caused by commit 944585a64f5e ("crypto: x86/aes-ni - remove special handling of AES in PCBC mode") I have used the version of the crypto tree from next-20181005 for today. -- Cheers, Stephen Rothwell
