This patchset adds the ability to mark gmfn values indicating that they are mfns. This disambiguates the case where a privileged domain might ask the hypervisor to insert a guest's mfn and the value is both a valid mfn, and a valid pfn for the priviledged domain.
The flag is added to Xen, used in pfn2mfn(), and exported via the devtree to dom0. A seperate patch to Linux reads the value of the flag and updates Linux to use the flag when mapping another domain's memory. Signed-off-by: Ryan Harper <[EMAIL PROTECTED]>
