From 48483b3290988952a593c6e66ca354c19f1a4350 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Sat, 26 Jan 2008 14:11:05 +0100 Subject: [S390] Get rid of additional_cpus kernel parameter. It caused only a lot of confusion. From now on cpu hotplug of up to NR_CPUS will work by default. If somebody wants to limit that then the possible_cpus parameter can be used.
