From e0982e90cd1ecf59818b137386b7f63debded9cc Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Wed, 26 Mar 2008 14:23:48 -0700 Subject: init: move setup of nr_cpu_ids to as early as possible Move the setting of nr_cpu_ids from sched_init() to start_kernel() so that it's available as early as possible. Note that an arch has the option of setting it even earlier if need be, but it should not result in a different value than the setup_nr_cpu_ids() function.
