[XenPPC] [PATCH 0 of 2] [PATCH] xen: flag gmfns as mfns

[Ryan Harper <ryanh@xxxxxxxxxx>]

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.
