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

Pull rdma updates from Jason Gunthorpe:
 "Again another fairly quiet cycle with few notable core code changes
  and the usual variety of driver bug fixes and small improvements.

   - Various driver updates and bug fixes for siw, bnxt_re, hns, qedr,
     iw_cxgb4, vmw_pvrdma, mlx5

   - Improvements in SRPT from working with iWarp

   - SRIOV VF support for bnxt_re

   - Skeleton kernel-doc files for drivers/infiniband

   - User visible counters for events related to ODP

   - Common code for tracking of mmap lifetimes so that drivers can link
     HW object liftime to a VMA

   - ODP bug fixes and rework

   - RDMA READ support for efa

   - Removal of the very old cxgb3 driver"
