Patchset annotates arch/* uses of ->thread_info. Ones that really are about access of thread_info of given process are simply switched to task_thread_info(task); ones that deal with access to objects on stack are switched to new helper - task_stack_page(). A _lot_ of the latter are actually open-coded instances of "find where pt_regs are"; those are consolidated into task_pt_regs(task) (many architectures actually have such helper already). Note that these annotations are not mandatory - any code not converted to these helpers still works. However, they clean up a lot of places and have actually caught a number of bugs, so converting out of tree ports would be a good idea... As an example of breakage caught by that stuff, see i386 pt_regs mess - we used to have it open-coded in a bunch of places and when back in April Stas had fixed a bug in copy_thread(), the rest had been left out of sync. That required two followup patches (the latest - just before 2.6.15) _and_ still had left /proc/*/stat eip field broken. Try ps -eo eip on i386 and watch the junk... This patch: new helper - task_stack_page(task). Returns pointer to the memory object containing task stack; usually thread_info of task sits in the beginning of that object.
