From 3ee1062b4ee82a56294808a065b64f4bc6781a56 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 12 Aug 2008 15:08:40 -0700 Subject: cpu hotplug: s390 doesn't support additional_cpus anymore. s390 doesn't support the additional_cpus kernel parameter anymore since a long time. So we better update the code and documentation to reflect that.

In the event BIOS doesn't mark such hot-pluggable cpus as disabled entries, one could use this parameter "additional_cpus=x" to represent those cpus in the cpu_possible_map. -s390 uses the number of cpus it detects at IPL time to also the number of bits -in cpu_possible_map.
