commit 230d7726ce55114c5c32c440c5928f104a085ba6

    memmmap: Use biosmem_addr_available rather than vm_page_lookup_pa
    The segment code actually has vm_page entries for reserved pages, and
    thus memmmap would reject mapping ACPI pages. Taking the information
    from biosmem is much more precise, and indeed knows all hardware quirks
    which can now be dropped from memmmap.

    Fix rejecting the mapping of some pages
    The memmmap method may reject some offsets (because it falls in non-device
    ranges), so device_map_page has to notice this and report the error.
    device_pager_data_request then has to notice as well and report.
