Thank you for the comment.

I considered about it well, and think that a new option '-X' is
good for excluding all the user domain pages. I will merge your
patch with this option.

I think it is better that the dump_level is used for excluding
only linux's pages. If the dump_level for linux is added after
the one for xen, the dump_level probably becomes strange like
the following:

       |               linux              | Xen | linux
       +----------------------------------+-----+-------
 Dump  | zero  cache  cache    user  free |     | some
 Level | page  page   private  data  page | Xen | page
-------+----------------------------------+-----+-------
    1  |  X
    2  |        X
    4  |        X      X
    8  |                        X
   16  |                              X
   32  |                                     X
   64  |                                           X

Sorry, I should have considered about it before posting the last mail.
