2017-02-14IB/umem: Update on demand page (ODP) supportArtemy Kovalyov3-15/+96
Currently ODP MR may explicitly register virtual address space area of limited length. This change allows MR to cover entire process virtual address space dynamicaly adding/removing translation entries to device MTT. Add following changes to support implicit MR: * Allow umem to be zero size to back-up implicit MR. * Add new function ib_alloc_odp_umem() to add virtual memory regions to implicit MR dynamically on demand. * Add new function rbt_ib_umem_lookup() to find dynamically added virtual memory regions. * Expose function rbt_ib_umem_for_each_in_range() to other modules and make it safe Signed-off-by: Artemy Kovalyov <artemyko@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>
