Busy today (want to reply to Christian) but

a) Re: performance, we would want something like
    vmf_insert_pfns_prot(), similar to vm_insert_pages(), to bulk-insert
    multiple PFNs.

b) Re: PAT, we'll have to figure out why PAT information is wrong here
    (was there no previous PAT reservation from the driver?), but IF we
    really have to override, we'd want a way to tell
    vmf_insert_pfn_prot() to force the selected caching mode.
