Subject: [RFC PATCH v3 24/31] init/main: call memlayout_global_init() in start_kernel().
Date: Thu,  2 May 2013 17:00:56 -0700	[thread overview]
Message-ID: <1367539263-19999-25-git-send-email-cody@linux.vnet.ibm.com> (raw)
In-Reply-To: <1367539263-19999-1-git-send-email-cody@linux.vnet.ibm.com>

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?).
