Hi Stefano,

I like this. I think it might make sense to call it
gnttab_page_grant_foreign_access_ref_one to make clear that it is only
granting the first 4K.

Will do.

In the future we could introduce a new function, called
gnttab_page_grant_foreign_access_ref, that grants all 4K in the page.

Unless having a different prototype it won't be possible to do it. This 
is because one ref = one grant. We would need a list of grant.

In any case
