Yes, this should do, thanks! I'd also suggest to leave a comment like
/*
* This function can get preemted and migrate to a different CPU
* but this doesn't matter. We just need to assign
* reenlightenment notification to some online CPU. In case this
* CPU goes offline, hv_cpu_die() will re-assign it to some
* other online CPU.
