Hi all,

After merging the crypto tree, today's linux-next build (powerpc
pseries_le_defconfig) failed like this:

arch/powerpc/crypto/p10_aes_gcm.o: warning: objtool: .text+0x884: unannotated intra-function call
arch/powerpc/crypto/aesp8-ppc.o: warning: objtool: aes_p8_set_encrypt_key+0x44: unannotated intra-function call
ld: arch/powerpc/crypto/p10_aes_gcm.o: ABI version 1 is not compatible with ABI version 2 output
ld: failed to merge target specific data of file arch/powerpc/crypto/p10_aes_gcm.o

Caused by commit

  ca68a96c37eb ("crypto: p10-aes-gcm - An accelerated AES/GCM stitched implementation")

I have applied the following hack for today.
