I get the following section mismatch when building linux-next:

WARNING: vmlinux.o(.text+0xc93f32): Section mismatch in reference from the function vcpu_hotplug() to the function .cpuinit.text:cpu_up()
The function vcpu_hotplug() references
the function __cpuinit cpu_up().
This is often because vcpu_hotplug lacks a __cpuinit 
annotation or the annotation of cpu_up is wrong.

Is this a benign warning?
