We use large pages, and in fact we are forced to a special area to

Consider it a permanent large page (64M) that is used for real mode,
this is our minimum memory.
In order to decrease a reservation that mean that memory must be
greater than this minimum memory by at least as much as we want to
decrease.  We also want to make sure that pages that are part of the
decrease do not come from the RMA.

Any thoughts on this would be appreciated.
Also, I know others are thinking about super-pages, any progress on
that with regard to grant transfers?

You could use the copy mode of operation supported by netfront/back.

Do you have more info on this?
My specific issue at the moment is how to deal with put_page()
