Subject: [patch 1/2] revert: x86: move prefill_possible_map calling early, fix
Date: Mon, 29 Sep 2008 18:27:56 -0400 [thread overview]
Message-ID: <20080929182756.4e33b06b@redhat.com> (raw)
From: Chuck Ebbert <cebbert@redhat.com>
revert: x86: move prefill_possible_map calling early, fix
revert 4a7017370aa0a94a00ae5b5705e9169cdcae5fb8
This 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.
