I am trying to extend the bounce frame which xen creates on the ring 1 stack.
---------------
| My_var |
|     SS     |
|   ESP    |
|  eflags  |
|     CS    |
|   EIP     |


I wish to add an integer variable My_var before xen adds SS to the bounce frame. What are the possible modifications I will have to make? Can you please suggest me proper places where I should make changes?

Thank you,
- Swapna
