signal.h need a definition of struct task_struct
This fixes these build errors on powerpc: In file included from arch/powerpc/mm/fault.c:18: include/linux/signal.h:239: error: 'struct task_struct' declared inside parameter list include/linux/signal.h:239: error: its scope is only this definition or declaration, which is probably not what you want include/linux/signal.h:240: error: 'struct task_struct' declared inside parameter list .. Exposed by commit e66eed651fd1 ("list: remove prefetching from regular list iterators"), which removed the include of <linux/prefetch.h> from <linux/list.h>. Without that, linux/signal.h no longer accidentally got the declaration of 'struct task_struct'. Fix by properly declaring the struct, rather than introducing any new header file dependency.
