    Fix stack assignment during CPU initialization
    
    There are two errors in the code. The first one is a missing
    $ sign in mov _stack, %esp. Thanks to Ronald G Minnich for
    catching that bug.
    
    The second bug is the 'incl %eax', which shouldn't be there, as
    there's no secondary CPU with index 0. CPU0 uses always the stack
    below _estack.
