compiling profiling broken

[Matthew Dillon]

    If someone would like a go at fixing this please do !  Else I'll tackle
    it in a week or two.  p.s. there might be other issues with profiling
    due to me not being too careful in my use of 'ret' in the assembly
    ('ret' is overridden in the profiling code to do a lot more then just
    'ret').

    I agree that profiling would be nice.  I'm not sure how relevant it will
    be with the MP lock in place, but it should still tell us something.
