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

Pull more rdma updates from Doug Ledford:
 "Items of note:

   - two patches fix a regression in the 4.15 kernel. The 4.14 kernel
     worked fine with NVMe over Fabrics and mlx5 adapters. That broke in
     4.15. The fix is here.

   - one of the patches (the endian notation patch from Lijun) looks
     like a lot of lines of change, but it's mostly mechanical in
     nature. It amounts to the biggest chunk of change in it (it's about
     2/3rds of the overall pull request).

  Summary:

   - Clean up some function signatures in rxe for clarity

   - Tidy the RDMA netlink header to remove unimplemented constants

   - bnxt_re driver fixes, one is a regression this window.

   - Minor hns driver fixes

   - Various fixes from Dan Carpenter and his tool

   - Fix IRQ cleanup race in HFI1

   - HF1 performance optimizations and a fix to report counters in the right units

   - Fix for an IPoIB startup sequence race with the external manager

   - Oops fix for the new kabi path

   - Endian cleanups for hns

   - Fix for mlx5 related to the new automatic affinity support"
