Date: Thu, 2 May 2013 17:00:55 -0700 From: Cody P Schafer <cody@...ux.vnet.ibm.com> To: Linux MM <linux-mm@...ck.org> Cc: LKML <linux-kernel@...r.kernel.org>, Cody P Schafer <cody@...ux.vnet.ibm.com>, Simon Jeons <simon.jeons@...il.com> Subject: [RFC PATCH v3 23/31] x86: memlayout: add a arch specific inital memlayout setter. On x86, we have numa_info specifically to track the numa layout, which is precisely the data memlayout needs, so use it to create an initial memlayout.
