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

Pull rdma fixes from Jason Gunthorpe:
 "Here is the first rc pull request for RDMA. This includes an important
  core fix for a regression in iWarp if SELinux is enabled, a fix for a
  compilation regression introduced in this merge window, and one
  obscure kconfig combination that oops's the kernel.

  For drivers, we have hns fixes needed to make their devices work on
  certain ARM IOMMU configurations, a stack data leak for hfi1, and
  various testing discovered -rc bug fixes for i40iw.

  This cycle we pushed back on the driver maintainers to have better
  commit messages for -rc material"
