From 14adf855baefad5ac3b545be23a64e6b61d6b74a Mon Sep 17 00:00:00 2001 From: Chuck Ebbert Date: Mon, 29 Sep 2008 18:29:42 -0400 Subject: x86: move prefill_possible_map calling early, fix, V2 Commit 4a701737 ("x86: move prefill_possible_map calling early, fix") is the wrong fix: prefill_possible_map() needs to be available even when CONFIG_HOTPLUG_CPU is not set. A followon patch will do that. Fix this correctly by making prefill_possible_map() available even when CONFIG_HOTPLUG_CPU is not set. The function is needed so that the number of possible CPUs can be determined. Tested on uniprocessor machine with CPU hotplug disabled.
