I am starting to think this patch makes even more sense than I thought. > Likewise we could kill UTASK_SSTEP, In fact we can kill utask->state. But I just realized we can also kill uprobe_deny_signal() and simplify arch_uprobe_xol_was_trapped() logic. But this needs some (simple) changes in arch/ code, so we need to wait until powerpc is merged.
