With this, when kexec-ing, we copy the code and start the slaves on their journey to the next kernel's spin loop as soon as we copy the kexec image into place. The kernel doesn't know exactly which slaves are spinning in kexec_wait. This allows us to pass more than max-cpus to the next kernel. But it also means that we might leave some behind. Moving the code here means they have the time it takes us to clear the hash table to wake up and move on. Moving the code any earlier would reuqire walking the image description to search for the code, which could span multiple pages.
