Pull rdma fixes from Doug Ledford:
"We have 5 small fixes for this pull request. One is a performance
regression, so not necessarily strictly a fix, but it was small and
reasonable and claimed to avoid thrashing in the scheduler, so I took
it. The remaining are all legitimate fixes that match the "we take
fixes any time" criteria.
Summary:
- One performance regression for hfi1
- One kasan fix for hfi1
- A couple mlx5 fixes
- A core oops fix"
