I can't build pseries_defconfig with this applied: /tmp/ccsjEdNB.s: Assembler messages: /tmp/ccsjEdNB.s: Error: .size expression for aes_p8_set_encrypt_key does not evaluate to a constant /tmp/ccsjEdNB.s: Error: .size expression for aes_p8_set_decrypt_key does not evaluate to a constant /tmp/ccsjEdNB.s: Error: .size expression for aes_p8_encrypt does not evaluate to a constant /tmp/ccsjEdNB.s: Error: .size expression for aes_p8_decrypt does not evaluate to a constant /tmp/ccsjEdNB.s: Error: .size expression for aes_p8_cbc_encrypt does not evaluate to a constant /tmp/ccsjEdNB.s: Error: .size expression for aes_p8_ctr32_encrypt_blocks does not evaluate to a constant That's with GCC 6.1.0 / binutils 2.26. Haven't debugged it any further. cheers
