  * ARM passes parameters to a callee in registers r0-r3. If there are more
  * than 4 parameters, the first four args are passed in registers the rest are
  * placed on the stack. This code pushes all parameters from registers into the
  * stack; thus, we keep all parameters on the stack as follows:
  * top - arg0, arg1, arg2, arg3 .... argN
  *
  * On top of that we push the return address, so we will know where to return
  * after the system call.
