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

Pull rdma updates from Jason Gunthorpe:
 "This contains a replacement driver for Intel iWarp hardware. This new
  driver supports the old ethernet hardware and also newer chips that
  can do ROCE.

  Other than that, this contains the typical mix of patches:

   - Driver updates and cleanups for bnxt_re, cxgb4, mlx4, and mlx5

   - Many static checker driven code clean ups, including a wide
     refcount_t conversion

   - Several series for the hns driver, more HIP09 HW capabilities,
     migration to new HW register manipulators, and code cleanups

   - Minor fixes and improvements in srp, rts, and cm

   - Improvements throughout for sysfs related code to use
     DEVICE_ATTR_*, make the ib_port sysfs first-class, and overall use
     sysfs APIs properly

   - Intel's new irdma driver replacing i40iw

   - rxe general clean ups and Memory Window support"
