The following patch cleans up the duplicated thread_info struct within each task. m68knommu only used the stack based one, but m68k mostly used the threaad_struct one. All other architectures only used the stack based one. Unfortunately it adds a couple of instructions into the exception processing paths. This could be reduced a little, since the act of calculating the current pointer (%a2) actually gets us the thread_info pointer. I have not taken advantage of this just yet, though this patch does take advantage of what the GET_CURRENT() macro does internally. I have tested this on ARAnyM and it seems to work just fine. Of course tested on ColdFire as well, no problems there. Thoughts on this one?
