    Subject[PATCH 3/6] xen mtrr: Use generic_validate_add_page()
    Date
    From: Mark McLoughlin <markmc@redhat.com>

    The hypervisor already performs the same validation, but
    better to do it early before getting to the range combining
    code.

    [ Impact: cleanup, avoid Xen console noise ]
