x86/xen: export xen_alloc_p2m_entry()
Rename alloc_p2m() to xen_alloc_p2m_entry() and export it. This is useful for ensuring that a p2m entry is allocated (i.e., not a shared missing or identity entry) so that subsequent set_phys_to_machine() calls will require no further allocations. Signed-off-by: David Vrabel <david.vrabel@citrix.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com> --- v3: - Make xen_alloc_p2m_entry() a nop on auto-xlate guests.
