    x86: modify hvm_memory_op() prototype
    
    hvm_memory_op() should take an unsigned long as cmd, like
    do_memory_op().
    
    As hvm_memory_op() is basically just calling do_memory_op() (or
    compat_memory_op()) passing through the parameters the cmd parameter
    should have no smaller size than that of the called functions.
