    Subject: [PATCH 06/13] IB/hfi1: update to new mmu_notifier semantic

    Call to mmu_notifier_invalidate_page() are replaced by call to
    mmu_notifier_invalidate_range() and thus call are bracketed by call to mmu_notifier_invalidate_range_start()/end()

    Remove now useless invalidate_page callback.
