From 7a302a9674593259866de4a9d5ae8edc03dc1934 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 14 May 2007 12:50:43 +0900 Subject: sh: Split out CPU topology initialization. Split out the CPU topology initialization to a separate file, and switch it to a percpu type, rather than an NR_CPUS array. At the same time, switch to only registering present CPUs, rather than using the possible CPU map.
