Patch in this message
Subject[PATCH] for_each_possible_cpu [1/19] defines for_each_possible_cpu
for_each_cpu() is for-loop cpu over cpu_possible_map.
for_each_online_cpu is for-loop cpu over cpu_online_map.
.....for_each_cpu() looks bad name.

This patch renames for_each_cpu() as for_each_possible_cpu().

I also wrote patches to replace all for_each_cpu with for_each_possible_cpu.
please confirm....

BTW, when HOTPLUC_CPU is not suppoted, using for_each_possible_cpu()
should be avoided, I think.

all patches are against 2.6.16-rc6-mm1.
