3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Thomas Gleixner <t...@linutronix.de> commit cce4517f33384c3794c759e206cc8e1bb6df146b upstream. alloc_task_struct_node() allocates THREAD_SIZE and maintains some weird refcount in the allocated memory. This never blew up as task_struct size on 32bit machines was always less than THREAD_SIZE Allocate just sizeof(struct task_struct) and get rid of the magic refcounting.
