This is dependent on the module patch, which Rusty is taking. I need to
see that he has it before this can go in. At least see it in linux-next.
Also, you should have Cc'd the linux-arch mailing list. I'll send it
there.

I ran it on 25 archs, and s390 hit:
/work/autotest/nobackup/cross-linux.git/arch/s390/kernel/jump_label.c: In function 'arch_jump_label_transform':
/work/autotest/nobackup/cross-linux.git/arch/s390/kernel/jump_label.c:58:13: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]
