From cce4517f33384c3794c759e206cc8e1bb6df146b Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 3 May 2012 09:02:47 +0000 Subject: frv: Use correct size for task_struct allocation 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.
