Hi all,

Arm never supported a M2P yet there are some helpers implemented to deal with
the common code. However, the implementation of mfn_to_gmfn is completely
bogus.

This series aims to properly disable the M2P on Arm.

Cheers,

    PV guest
  xen: arm: Stop returning a bogus GFN for the shared info
  xen: arm: Remove mfn_to_gfn() macro
  xen/mm: Provide dummy M2P-related helpers when the M2P is not
    supported
