Merge branch 'k.o/for-rc' into k.o/wip/dl-for-next

Several items of conflict have arisen between the RDMA stack's for-rc
branch and upcoming for-next work:

9fd4350ba895 ("IB/rxe: avoid double kfree_skb") directly conflicts with
2e47350789eb ("IB/rxe: optimize the function duplicate_request")

Patches already submitted by Intel for the hfi1 driver will fail to
apply cleanly without this merge

Other people on the mailing list have notified that their upcoming
patches also fail to apply cleanly without this merge
