Commit 7110c89bb8852ff8b0f88ce05b332b3fe22bd11e ("mmu: swap out round for ALIGN") replaced two calls to round/rounddown with ALIGN/ALIGN_DOWN, but erroneously applied ALIGN_DOWN to a different variable (addr) and left intended variable (tail) not rounded/ALIGNed.

Turning off the sink in this case causes various issues, because userspace expects it to stay on until it turns it off explicitly. Instead, turn the sink off and back on when a display is connected again. This dance seems necessary for link training to work correctly.

The boost frequency is only applied from the RPS worker while someone is waiting on a request and requested a boost. As such, when the user wishes to change the frequency, we have to kick the worker in order to re-evaluate whether to apply the boost frequency. v2: Check num_waiters to decide if we should kick the worker to handle boosting.

Currently, we only allow ourselves to prune the fences so long as all the waits completed (i.e. all the fences we checked were signaled), and that the reservation snapshot did not change across the wait. However, if we only waited for a subset of the reservation object, i.e. just waiting for the last writer to complete as opposed to all readers as well, then we would erroneously conclude we could prune the fences as indeed although all of our waits were successful, they did not represent the totality of the reservation object. v2: We only need to check the shared fences due to construction (i.e. all of the shared fences will be later than the exclusive fence, if any).

On the CP110 components which are present on the Armada 7K/8K SoC we need to explicitly enable the clock for the registers. However it is not needed for the AP8xx component, that's why this clock is optional. With this patch both clock have now a name, but in order to be backward compatible, the name of the first clock is not used. It allows to still use this clock with a device tree using the old binding.

Merge tag 'for-4.16/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix an uninitialized variable false warning in dm bufio - Fix DM's passthrough ioctl support to be race free against an underlying device being removed. - Fix corner-case of DM raid resync reporting if/when the raid becomes degraded during resync; otherwise automated raid repair will fail. - A few DM multipath fixes to make non-SCSI optimizations, that were introduced during the 4.16 merge, useful for all non-SCSI devices, rather than narrowly define this non-SCSI mode in terms of "nvme". This allows the removal of "queue_mode nvme" that really didn't need to be introduced. Instead DM core will internalize whether nvme-specific IO submission optimizations are doable and DM multipath will only do SCSI-specific device handler operations if SCSI is in use. * tag 'for-4.16/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm table: allow upgrade from bio-based to specialized bio-based variant dm mpath: remove unnecessary NVMe branching in favor of scsi_dh checks dm table: fix "nvme" test dm raid: fix incorrect sync_ratio when degraded dm: use blkdev_get rather than bdgrab when issuing pass-through ioctl dm bufio: avoid false-positive Wmaybe-uninitialized warning

git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma由 Linus Torvalds 提交于
Pull rdma fixes from Doug Ledford: - Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging from bugs under load to bad error case handling - There in one largish patch fixing the locking in bnxt_re to avoid a machine hard lock situation - A few core bugs on error paths - A patch to reduce stack usage in the new CQ API - One mlx5 regression introduced in this merge window - There were new syzkaller scripts written for the RDMA subsystem and we are fixing issues found by the bot - One of the commits (aa0de36a “RDMA/mlx5: Fix integer overflow while resizing CQ”) is missing part of the commit log message and one of the SOB lines. The original patch was from Leon Romanovsky, and a cut-n-paste separator in the commit message confused patchworks which then put the end of message separator in the wrong place in the downloaded patch, and I didn’t notice in time. The patch made it into the official branch, and the only way to fix it in-place was to rebase. Given the pain that a rebase causes, and the fact that the patch has relevant tags for stable and syzkaller, a revert of the munged patch and a reapplication of the original patch with the log message intact was done. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (25 commits) RDMA/mlx5: Fix integer overflow while resizing CQ Revert "RDMA/mlx5: Fix integer overflow while resizing CQ" RDMA/ucma: Check that user doesn't overflow QP state RDMA/mlx5: Fix integer overflow while resizing CQ RDMA/ucma: Limit possible option size IB/core: Fix possible crash to access NULL netdev RDMA/bnxt_re: Avoid Hard lockup during error CQE processing RDMA/core: Reduce poll batch for direct cq polling IB/mlx5: Fix an error code in __mlx5_ib_modify_qp() IB/mlx5: When not in dual port RoCE mode, use provided port as native IB/mlx4: Include GID type when deleting GIDs from HW table under RoCE IB/mlx4: Fix corruption of RoCEv2 IPv4 GIDs RDMA/qedr: Fix iWARP write and send with immediate RDMA/qedr: Fix kernel panic when running fio over NFSoRDMA RDMA/qedr: Fix iWARP connect with port mapper RDMA/qedr: Fix ipv6 destination address resolution IB/core : Add null pointer check in addr_resolve RDMA/bnxt_re: Fix the ib_reg failure cleanup RDMA/bnxt_re: Fix incorrect DB offset calculation RDMA/bnxt_re: Unconditionly fence non wire memory operations ...

As reported by Dan the parentheses is in the wrong place, and since unlikely() call returns either 0 or 1 it's never less than zero. The second issue is that signed integer overflows like "INT_MAX + 1" are undefined behavior. Since num_test_devs represents the number of devices, we want to stop prior to hitting the max, and not rely on the wrap arround at all. So just cap at num_test_devs + 1, prior to assigning a new device.

Fix userfaultfd_hugetlb on hosts which have more than 64 cpus. --------------------------- running userfaultfd_hugetlb --------------------------- invalid MiB Usage: <MiB> <bounces> [FAIL] Via userfaultfd.c we can know, hugetlb_size needs to meet hugetlb_size >= nr_cpus * hugepage_size. hugepage_size is often 2M, so when host cpus > 64, it requires more than 128M.
