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

Pull rdma updates from Jason Gunthorpe:
 "Small cycle, with some typical driver updates:

   - General code tidying in siw, hfi1, idrdma, usnic, hns rtrs and
     bnxt_re

   - Many small siw cleanups without an overeaching theme

   - Debugfs stats for hns

   - Fix a TX queue timeout in IPoIB and missed locking of the mcast
     list

   - Support more features of P7 devices in bnxt_re including a new work
     submission protocol

   - CQ interrupts for MANA

   - netlink stats for erdma

   - EFA multipath PCI support

   - Fix Incorrect MR invalidation in iser"
