From a1261f54611ec4ad6a7ab7080f86747e3ac3685b Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 13 Nov 2005 16:06:55 -0800 Subject: [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.
