2022-10-03net/mlx5e: Improve MTT/KSM alignmentMaxim Mikityanskiy
Make mlx5e_mpwrq_mtts_per_wqe take into account that KSM requires smaller alignment than MTT. Ensure that there is always an even amount of MTTs in a UMR WQE, so that complete octwords are formed, and no garbage is mapped. Drop extra alignment in MLX5_MTT_OCTW that may cause setting too big ucseg->xlt_octowords, also leading to mapping garbage. Generalize some calculations by introducing the MLX5_OCTWORD constant.

2022-10-03net/mlx5e: xsk: Use umr_mode to calculate striding RQ parametersMaxim Mikityanskiy
Instead of passing the unaligned flag, pass an enum that indicates the UMR mode. The next commit will add the third mode (KLM for certain configurations of XSK), which will be added to this enum instead of adding another bool flag everywhere.

2022-10-03net/mlx5e: xsk: Improve need_wakeup logicMaxim Mikityanskiy
XSK need_wakeup mechanism allows the driver to stop busy waiting for buffers when the fill ring is empty, yield to the application and signal it that the driver needs to be waken up after the application refills the fill ring. Add protection against the race condition on the RX (refill) side: if the application refills buffers after xskrq->post_wqes is called, but before mlx5e_xsk_update_rx_wakeup, NAPI will exit, skipping taking these buffers to the hardware WQ, and the application won't wake it up again. Optimize the whole need_wakeup logic, removing unneeded flows, to compensate for this new check.

2022-10-03net: mvpp2: fix mvpp2 debugfs leakRussell King (Oracle)
When mvpp2 is unloaded, the driver specific debugfs directory is not removed, which technically leads to a memory leak. However, this directory is only created when the first device is probed, so the hardware is present. Removing the module is only something a developer would to when e.g. testing out changes, so the module would be reloaded. So this memory leak is minor. The original attempt in commit fe2c9c61f668 ("net: mvpp2: debugfs: fix memory leak when using debugfs_lookup()") that was labelled as a memory leak fix was not, it fixed a refcount leak, but in doing so created a problem when the module is reloaded - the directory already exists, but mvpp2_root is NULL, so we lose all debugfs entries. This fix has been reverted. This is the alternative fix, where we remove the offending directory whenever the driver is unloaded.

2022-10-03net: ipa: update commentsAlex Elder
This patch just updates comments throughout the IPA code. Transaction state is now tracked using indexes into an array rather than linked lists, and a few comments refer to the "old way" of doing things. The description of how transactions are used was changed to refer to "operations" rather than "commands", to (hopefully) remove a possible ambiguity. IPA register offsets and fields are now handled differently as well, and the register documentation is updated to better describe the code. A few minor updates to comments were made (e.g., adding a missing word, fixing a typo or punctuation, etc.). Finally, the local macro atomic_dec_not_zero() is no longer used, so it is deleted.

KMSAN adds extra metadata fields to struct page, so it does not fit into 64 bytes anymore. This change leads to increased memory consumption of the nvdimm driver, regardless of whether the kernel is built with KMSAN or not.

2022-10-03mm: hugetlb: eliminate memory-less nodes handlingMuchun Song
The memory-notify-based approach aims to handle meory-less nodes, however, it just adds the complexity of code as pointed by David in thread [1]. The handling of memory-less nodes is introduced by commit 4faf8d950ec4 ("hugetlb: handle memory hot-plug events"). >From its commit message, we cannot find any necessity of handling this case. So, we can simply register/unregister sysfs entries in register_node/unregister_node to simlify the code. BTW, hotplug callback added because in hugetlb_register_all_nodes() we register sysfs nodes only for N_MEMORY nodes, seeing commit 9b5e5d0fdc91, which said it was a preparation for handling memory-less nodes via memory hotplug. Since we want to remove memory hotplug, so make sure we only register per-node sysfs for online (N_ONLINE) nodes in hugetlb_register_all_nodes(). https://lore.kernel.org/linux-mm/60933ffc-b850-976c-78a0-0ee6e0ea9ef0@redhat.com/ [1] Link: https://lkml.kernel.org/r/20220914072603.60293-3-songmuchun@bytedance.com Suggested-by: David Hildenbrand <david@redhat.com> Signed-off-by: Muchun Song <songmuchun@bytedance.com> Acked-by: David Hildenbrand <david@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Mike Kravetz <mike.kravetz@oracle.com> Cc: Oscar Salvador <osalvador@suse.de> Cc: Rafael J.

2022-10-03mm: hugetlb: simplify per-node sysfs creation and removalMuchun Song
Patch series "simplify handling of per-node sysfs creation and removal", v4. This patch (of 2): The following commit offload per-node sysfs creation and removal to a kworker and did not say why it is needed. And it also said "I don't know that this is absolutely required". It seems like the author was not sure as well. Since it only complicates the code, this patch will revert the changes to simplify the code. 39da08cb074c ("hugetlb: offload per node attribute registrations") We could use memory hotplug notifier to do per-node sysfs creation and removal instead of inserting those operations to node registration and unregistration. Then, it can reduce the code coupling between node.c and hugetlb.c. Also, it can simplify the code.

2022-10-03zram: do not waste zram_table_entry flags bitsSergey Senozhatsky
zram_table_entry::flags stores object size in the lower bits and zram pageflags in the upper bits. However, for some reason, we use 24 lower bits, while maximum zram object size is PAGE_SIZE, which requires PAGE_SHIFT bits (up to 16 on arm64). This wastes 24 - PAGE_SHIFT bits that we can use for additional zram pageflags instead. Also add a BUILD_BUG_ON() to alert us should we run out of bits in zram_table_entry::flags.

2022-10-03drm/i915: Reject excessive dotclocks earlyVille Syrjälä
Make sure modes with crazy big dotclocks are rejected early, so as to not cause problems for subsequent code via integer overflows and whatnot. These would eventually be rejected in intel_crtc_compute_pipe_mode() but that is now too late as we do the clock computations a bit earlier than that. And we don't want to just reorder the two since we still want to check the final computed dotclock against the hardware limit to make sure we didn't end up above the limit due to rounding/etc. Fixes: 0ff0e219d9b8 ("drm/i915: Compute clocks earlier") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220927182455.3422-1-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com> (cherry picked from commit df2f59c5857b56a5cc40b6562b032c5d8d50cdfc) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
