Aren't you missing a _gfn here?
_gfn(mfn_to_gfn(d, _mfn(__virt_to_mfn(d->shared_info))));
Patch #3 of this series convert mfn_to_gfn to use typesafe MFN & GFN. So the
function now return a gfn_t.
Ah! Somehow I am missing patches 2-3-4 in my inbox. I'll try to get them
from the archive.
Because they are x86 specific :). The rationale of implementing
domain_shared_info_gfn() in common code is any arch using M2P should
provide a similar helper.
Arm doesn't have an M2P, hence why mfn_to_gfn is not existent.
