From b636f1379eefe6eba931deaa386605bc7ac623e7 Mon Sep 17 00:00:00 2001 From: Matt Evans Date: Mon, 7 Jun 2010 21:38:18 +0000 Subject: [PATCH] powerpc/kexec: Wait for online/possible CPUs only. kexec_perpare_cpus_wait() iterates i through NR_CPUS to check paca[i].kexec_state of each to make sure they have quiesced. However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily valid and we overrun the array; spurious "cpu is not possible, ignoring" errors result. This patch iterates for_each_online_cpu so stays within the bounds of paca[] -- and every CPU is now 'possible'.
