[PATCH] m68k: introduce task_thread_info
new helper - task_thread_info(task). On platforms that have thread_info
allocated separately (i.e. in default case) it simply returns
task->thread_info. m68k wants (and for good reasons) to embed its thread_info
into task_struct. So it will (in later patch) have task_thread_info() of its
own. For now we just add a macro for generic case and convert existing
instances of its body in core kernel to uses of new macro. Obviously safe -
all normal architectures get the same preprocessor output they used to get.
