[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. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
