clang points out that the declaration of cio_irb does not match the
definition exactly, it is missing the alignment attribute:
../drivers/s390/cio/cio.c:50:1: warning: section does not match previous declaration [-Wsection]
DEFINE_PER_CPU_ALIGNED(struct irb, cio_irb);
^

__percpu __attribute__((section(PER_CPU_BASE_SECTION sec))) \

Use DECLARE_PER_CPU_ALIGNED() here, to make the two match.
