The tricky part here is that task_pt_regs() on m68k works *only* for process inside do_signal(). However, we need something much simpler - pt_regs of a process inside do_signal() may be at different offsets from the stack bottom, depending on the way we'd entered the kernel, but for a task inside sys_execve() it *is* at constant offset. Moreover, for a kernel thread about to become a userland process the same location is also fine - setting sp to that will leave the kernel stack pointer at the very bottom of the kernel stack when we finally switch to userland.
