So as far as I can tell we now have to colliding values in domctl.h:

#define XEN_DOMCTL_PFINFO_LPINTAB (0x1U<<31)
#define XEN_DOMCTL_PFINFO_PAGEDTAB (0x8U<<28)

Was it determined that this is not (going to be) a problem? It's just
the tools interface, but it's a public header...

Also there are several places were gmfn_to_mfn() was replaced by
mfn_x(gfn_to_mfn()), but the p2m_is_valid() check that the former
does was lost. Again - has it been determined that this will never
cause any problem?
