Subject: [PATCH] [PATCH] CPU hotplug printk fix

In the cpu hotplug case, per-cpu data possibly isn't initialized even the
system state is 'running'.  As the comments say in the original code, some
console drivers assume per-cpu resources have been allocated.  radeon fb is
one such driver, which uses kmalloc.  After a CPU is down, the per-cpu data
of slab is freed, so the system crashed when printing some info.
