Hi all,

Arm never supported an 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. See patch #8 for the
rationale regarding the lack of M2P on Arm.

While looking at the code, I also continue to convert some code to use
typesafe MFN/GFN.

Cheers,

Julien Grall (9):
  xen/arm: Use mfn_to_pdx instead of pfn_to_pdx when possible
  xen/x86: Constify the parameter "d" in mfn_to_mfn
  xen/x86: Use mfn_to_gfn rather than mfn_to_gmfn
  xen/grant-table: Make arch specific macros typesafe
  xen: Convert hotplug page function to use typesafe MFN
  xen: Convert is_xen_fixed_mfn to use typesafe MFN
  xen: Convert is_xen_heap_mfn to use typesafe MFN
  xen: Introduce HAS_M2P config and use to protect mfn_to_gmfn call
  xen: Remove mfn_to_gmfn macro
