HVM does not allow direct PTE modification, so instead we request that Xen change its internal p2m mappings on the allocated pages and map the memory into userspace normally. Note: The HVM path for map and unmap is slightly different: HVM keeps the pages mapped until the area is deleted, while the PV case (use_ptemod being true) must unmap them when userspace unmaps the range. In the normal use case, this makes no difference to users since unmap time is deletion time.
