    m68k: switch to generic sys_execve()/kernel_execve() · d878d6da

    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.
