From 890db403d59fbeaf273ed019d0b1862223d80a9a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 1 Apr 2009 03:13:15 -0700 Subject: [PATCH] sparc: Call OF and MD cpu scanning explicitly from paging_init() We need to split up the cpu present mask setup from the cpu_data initialization, and this is a first step towards that.
