Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:

 - Usual minor updates and fixes for bnxt_re, hfi1, rxe, mana, iser,
   mlx5, vmw_pvrdma, hns

 - Make rxe work on tun devices

 - mana gains more standard verbs as it moves toward supporting
   in-kernel verbs

 - DMABUF support for mana

 - Fix page size calculations when memory registration exceeds 4G

 - On Demand Paging support for rxe

 - mlx5 support for RDMA TRANSPORT flow tables and a new ucap mechanism
   to access control use of them

 - Optional RDMA_TX/RX counters per QP in mlx5
