Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma fixes from Doug Ledford: "I had thought at the time of the last pull request that there wouldn't be much more to go, but several things just kept trickling in over the last week. Instead of just the six patches to bnxt_re that I had anticipated, there are another five IPoIB patches, two qedr patches, and a few other miscellaneous patches. The bnxt_re patches are more lines of diff than I like to submit this late in the game. That's mostly because of the first two patches in the series of six. I almost dropped them just because of the lines of churn, but on a close review, a lot of the churn came from removing duplicated code sections and consolidating them into callable routines. I felt like this made the number of lines of change more acceptable, and they address problems, so I left them. The remainder of the patches are all small, well contained, and well understood. These have passed 0day testing, but have not been submitted to linux-next (but a local merge test with your current master was without any conflicts). Summary: - A fix for fix eea40b8f624 ("infiniband: call ipv6 route lookup via the stub interface") - Six patches against bnxt_re...the first two are considerably larger than I would like, but as they address real issues I went ahead and submitted them (it also helped that a good deal of the churn was removing code repeated in multiple places and consolidating it to one common function) - Two fixes against qedr that just came in - One fix against rxe that took a few revisions to get right plus time to get the proper reviews - Five late breaking IPoIB fixes - One late cxgb4 fix" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: rdma/cxgb4: Fix memory leaks during module exit IB/ipoib: Fix memory leak in create child syscall IB/ipoib: Fix access to un-initialized napi struct IB/ipoib: Delete napi in device uninit default IB/ipoib: Limit call to free rdma_netdev for capable devices IB/ipoib: Fix memory leaks for child interfaces priv rxe: Fix a sleep-in-atomic bug in post_one_send RDMA/qedr: Add 64KB PAGE_SIZE support to user-space queues RDMA/qedr: Initialize byte_len in WC of READ and SEND commands RDMA/bnxt_re: Remove FMR support RDMA/bnxt_re: Fix RQE posting logic RDMA/bnxt_re: Add HW workaround for avoiding stall for UD QPs RDMA/bnxt_re: Dereg MR in FW before freeing the fast_reg_page_list RDMA/bnxt_re: HW workarounds for handling specific conditions RDMA/bnxt_re: Fixing the Control path command and response handling IB/addr: Fix setting source address in addr6_resolve()
