This is the first step to make ODP use the owning_mm that is now part of struct ib_umem. Each ODP umem is linked to a single per_mm structure, which in turn, is linked to a single mm, via the embedded mmu_notifier. This first patch introduces the structure and reworks eveything to use it. This also needs to introduce tgid into the ib_ucontext_per_mm, as get_user_pages_remote() requires the originating task for statistics tracking.
