Intel hit me with a series of fixes for TID processing. Mellanox hit me with a series for their UMR memory support. And we had one fix for siw that fixes the 32bit build warnings and because of the number of casts that had to be changed to properly silence the warnings, that one patch alone is a full 40% of the LOC of this entire pull request. Given that this is the initial release kernel for siw, I'm trying to fix anything in it that we can, so that adds to the impetus to take fixes for it like this one. I had to do a rebase early in the week. Jason had thought he put a patch on the rc queue that he needed to be there so he could base some work off of it, and it had actually not been placed there. So he asked me (on Tuesday) to fix that up before pushing my wip branch to the official rc branch. I did, and that's why the early patches look like they were all committed at the same time on Tuesday. That bunch had been in my queue prior. The various patches all pass my test for being legitimate fixes and not attempts to slide new features or development into a late rc. Well, they were all fixes with the exception of a couple clean up patches people wrote for making the fixes they also wrote better (like a cleanup patch to move UMR checking into a function so that the remaining UMR fix patches can reference that function), so I left those in place too. My apologies for the LOC count and the number of patches here, it's just how the cards fell this cycle. Summary: - Fix siw buffer mapping issue - Fix siw 32/64 casting issues - Fix a KASAN access issue in bnxt_re - Fix several memory leaks (hfi1, mlx4) - Fix a NULL deref in cma_cleanup - Fixes for UMR memory support in mlx5 (4 patch series) - Fix namespace check for restrack - Fixes for counter support - Fixes for hfi1 TID processing (5 patch series) - Fix potential NULL deref in siw - Fix memory page calculations in mlx5" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (21 commits) RDMA/siw: Fix 64/32bit pointer inconsistency RDMA/siw: Fix SGL mapping issues RDMA/bnxt_re: Fix stack-out-of-bounds in bnxt_qplib_rcfw_send_message infiniband: hfi1: fix memory leaks infiniband: hfi1: fix a memory leak bug IB/mlx4: Fix memory leaks RDMA/cma: fix null-ptr-deref Read in cma_cleanup IB/mlx5: Block MR WR if UMR is not possible IB/mlx5: Fix MR re-registration flow to use UMR properly IB/mlx5: Report and handle ODP support properly IB/mlx5: Consolidate use_umr checks into single function RDMA/restrack: Rewrite PID namespace check to be reliable RDMA/counters: Properly implement PID checks IB/core: Fix NULL pointer dereference when bind QP to counter IB/hfi1: Drop stale TID RDMA packets that cause TIDErr IB/hfi1: Add additional checks when handling TID RDMA WRITE DATA packet IB/hfi1: Add additional checks when handling TID RDMA READ RESP packet IB/hfi1: Unsafe PSN checking for TID RDMA READ Resp packet IB/hfi1: Drop stale TID RDMA packets RDMA/siw: Fix potential NULL de-ref ... |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
