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_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.
