    arm: Prevent compilation of old, experimental SMP support
    
    The ARM SMP feature was added a long time ago and has never really been
    used by anyone since. We are still always compiling cpu_info() even
    though we don't use it, and it makes some dangerous assumptions about
    stack alignment that are not guaranteed anywhere.
    
    I'm planning to change the way the stack boundaries are defined. Rather
    than trying to work that into this unsafe, unused and hard to test
    feature, I think we should just seal it off with police tape and make
    sure that if anyone ever tries to use it again (which currently seems
    unlikely), they get forced to do their due diligence on making sure it
    works as intended.
    
    BUG=None
    TEST=Compiled Veyron_Pinky.
