It turns out we can't use num_possible_cpus() that early on boot, as
it hasn't yet been properly set, nor other helpers, a late setup for
big CPUs is therefore needed in order to use num_possible_cpus().
That also means we can use kzalloc() instead. I'll send a v4 and
I think we should test this a bit so will send as RFT.
