[ N.B. Don't merge this without first ensuring the kernel-side patch has propagated far enough, ideally upstream. ]
This patch causes secondary CPUs to enter a low power state while
waiting to be woken during booting. Without the corresponding kernel
patch to send an event, the secondary CPUs won't come online.
