Subject: percpu: add dummy pcpu_lpage_remapped() for !CONFIG_SMP
X-Git-Tag: firefly_0821_release~12956^2^2~21
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a76761b621bcd8336065c4fe3a74f046858bc34c;p=firefly-linux-kernel-4.4.55.git

percpu: add dummy pcpu_lpage_remapped() for !CONFIG_SMP

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