Adds support for Numascale NumaChip large-SMP systems. It is needed to enable the booting of more than ~168 cores. v2: - [Steffen] enumerate only accessible northbridges - [Daniel] rediffed and validated against 3.1-rc10 v3: - [Daniel] use x86_init core numbering override - [Daniel] cleanups as per feedback v4: - [Daniel] use updated x86_cpuinit override v5: - drop disabling interrupts locally, as ISR write is atomic; drop delay - added read-mostly annotations where appropriate - require CONFIG_SMP, so drop conditional path Workload tested on 96 cores/16 sockets.
