I would name it map_regions_mattr (or something similar) to stop people 
using this helper to map real RAM.

I overlooked it when I reviewed {,un}map_regions_rw_cache. p2m_access_t 
is for memaccess to restrict the permission. The helper should always 
use d->arch.p2m.default_access.

Can you fix it in a separate patch and request for backport to Xen 4.7?
