Not functional change intended

Is there a reason to not make all guest accessors tyep-safe instead?

Could you clarify what you mean? MFN and xen_pfn_t have different type on
Arm. So I am not sure how you would be able to make them typesafe.

What I meant was to make copy_{to,from}_guest* type-safe. I just feel it
a bit strange you only created a wrapper for this file. I wonder why.

Oh, I can have a look at that.

Note I'm just asking question. That's not necessarily a good idea to
turn them all in the end.
