From 97db7fbfc7712bc403330c81c04ddfa82b335bce Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Fri, 31 Mar 2006 02:30:26 -0800 Subject: [PATCH] for_each_possible_cpu: s390 for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu.
