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

Pull rdma updates from Jason Gunthorpe:
 "This cycle we got a new RDMA driver "ERDMA" for the Alibaba cloud
  environment. Otherwise the changes are dominated by rxe fixes.

  There is another RDMA driver on the list that might get merged next
  cycle, 'MANA' for the Azure cloud environment.

  Summary:

   - Bug fixes and small features for irdma, hns, siw, qedr, hfi1, mlx5

   - General spelling/grammer fixes

   - rdma cm can follow changes in neighbours for control packets

   - Significant amounts of rxe fixes and spec compliance changes

   - Use the modern NAPI API

   - Use the bitmap API instead of open coding

   - Performance improvements for rtrs

   - Add the ERDMA driver for Alibaba cloud

   - Fix a use after free bug in SRP"
