Xen devel - May 2008 - [PATCH][HVM] stdvga: handle 64bit io operations

Hi!

In struct ioreq  are the "addr", "size", "count"
and "data" 64bit fields.
So handle 64bit operations in stdvga instead of throwing away the upper 32bits 
(see attached patch).

This fixes some noisy xen messages like "invalid io size: 8".
