[RFC PATCH v2 18/25] init/main: call memlayout_global_init() in start_kernel().

From: Cody P Schafer
Date: Thu Apr 11 2013 - 21:14:51 EST

memlayout_global_init() initializes the first memlayout, which is
assumed to match the initial page-flag nid settings.

This is done in start_kernel() as the initdata used to populate the
memlayout is purged from memory early in the boot process (XXX: When?).
