[PATCH] percpu: add dummy pcpu_lpage_remapped() for !CONFIG_SMP

[Tejun Heo]

!CONFIG_SMP was missing pcpu_lpage_remapped() definition causing build
failure.  Add dummy implementation.  This was discovered by linux-next
testing.

Yeap, it was missing dummy definition on !CONFIG_SMP.  This patch
fixes it.  Committed to percpu#for-next.  Thanks.
