Both Mellanox and Intel had a series of -rc fixes that landed this week. The Mellanox bunch is spread throughout the stack and not just in their driver, where as the Intel bunch was mostly in the hfi1 driver. And, several of the fixes in the hfi1 driver were more than just simple 5 line fixes. As a result, the hfi1 driver fixes has a sizable LOC count. Everything else is as one would expect in an RC cycle in terms of LOC count. One item that might jump out and make you think "That's not an rc item" is the fix that corrects a typo. But, that change fixes a typo in a user visible API that was just added in this merge window, so if we fix it now, we can fix it. If we don't, the typo is in the API forever. Another that might not appear to be a fix at first glance is the Simplify mlx5_ib_cont_pages patch, but the simplification allows them to fix a bug in the existing function whenever the length of an SGE exceeded page size. We also had to revert one patch from the merge window that was wrong. Summary: - a few core fixes - a few ipoib fixes - a few mlx5 fixes - a 7-patch hfi1 related series" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: IB/hfi1: Unsuccessful PCIe caps tuning should not fail driver load IB/hfi1: On error, fix use after free during user context setup Revert "IB/ipoib: Update broadcast object if PKey value was changed in index 0" IB/hfi1: Return correct value in general interrupt handler IB/hfi1: Check eeprom config partition validity IB/hfi1: Only reset QSFP after link up and turn off AOC TX IB/hfi1: Turn off AOC TX after offline substates IB/mlx5: Fix NULL deference on mlx5_ib_update_xlt failure IB/mlx5: Simplify mlx5_ib_cont_pages IB/ipoib: Fix inconsistency with free_netdev and free_rdma_netdev IB/ipoib: Fix sysfs Pkey create<->remove possible deadlock IB: Correct MR length field to be 64-bit IB/core: Fix qp_sec use after free access IB/core: Fix typo in the name of the tag-matching cap struct
