Hi, Is KSTK_ESP supposed to return the kernel mode SP of a sleeping task or is it supposed to provide the user mode SP at the time of last kernel entry ? The 2 non arch users of the API expect the user mode SP semantics: * vm_is_stack_for_task() - to annotate /proc/<pid>/maps stack vma - which is shere Alexey noted this. * do_task_stat() ARC port uses these for unwinding the task of a sleeping task (hence kernel mode SP semantics). metag (from the looks of it) also seem to provide kernel mode value, while most others seem to provide the user mode variant. I can fix ARC to work with expectation of generic code, but wanted to understand anyways.
