Subject: linux-next: build failure after merge of the crypto tree

Hi all,

After merging the crypto tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ld: warning: discarding dynamic section .glink
ld: warning: discarding dynamic section .plt
ld: linkage table error against `sm2_compute_z_digest'
ld: stubs don't match calculated size
ld: can not build stubs: bad value
ld: crypto/asymmetric_keys/x509_public_key.o: in function `x509_get_sig_params':
x509_public_key.c:(.text+0x474): undefined reference to `sm2_compute_z_digest'

Possibly caused by commit

  e5221fa6a355 ("KEYS: asymmetric: Move sm2 code into x509_public_key")

This looks like it may be a compiler bug?  Maybe the deep ternary
expressions may be contributing to that? (cc'ing the ppc guys in case
they have any ideas.)

I have reverted that commit (and the following one) for today.
