Pull rdma fixes from Doug Ledford: "This is probably our last -rc pull request. We don't have anything else outstanding at the moment anyway, and with the summer months on us and people taking trips, I expect the next weeks leading up to the merge window to be pretty calm and sedate. This has two simple, no brainer fixes for the EFA driver. Then it has ten not quite so simple fixes for the hfi1 driver. The problem with them is that they aren't simply one liner typo fixes. They're still fixes, but they're more complex issues like livelock under heavy load where the answer was to change work queue usage and spinlock usage to resolve the problem, or issues with orphaned requests during certain types of failures like link down which required some more complex work to fix too. They all look like legitimate fixes to me, they just aren't small like I wish they were. Summary: - 2 minor EFA fixes - 10 hfi1 fixes related to scaling issues" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: RDMA/efa: Handle mmap insertions overflow RDMA/efa: Fix success return value in case of error IB/hfi1: Handle port down properly in pio IB/hfi1: Handle wakeup of orphaned QPs for pio IB/hfi1: Wakeup QPs orphaned on wait list after flush IB/hfi1: Use aborts to trigger RC throttling IB/hfi1: Create inline to get extended headers IB/hfi1: Silence txreq allocation warnings IB/hfi1: Avoid hardlockup with flushlist_lock IB/hfi1: Correct tid qp rcd to match verbs context IB/hfi1: Close PSM sdma_progress sleep window IB/hfi1: Validate fault injection opcode user input
