2025-03-05hwmon: (pt5161l) Use per-client debugfs entryWolfram Sang
The I2C core now offers a debugfs-directory per client. Use it and remove the custom handling. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Link: https://lore.kernel.org/r/20250305123149.16990-2-wsa+renesas@sang-engineering.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2025-03-04hwmon: Fix the missing of 'average' word in hwmon_power_attr_templatesHuisong Li
The string "power%d_interval_max" and "power%d_interval_min" in the hwmon_power_attr_templates[] are corresponding to the sysfs interface name of hwmon_power_average_interval_max and hwmon_power_average_interval_min. But the 'average' word is missing in two strings. Fortunately, there is no driver to use it yet.

2025-03-02hwmon: (acpi_power_meter) Fix the fake power alarm reportingHuisong Li
We encountered a problem that a fake power alarm is reported to user on the platform unsupported notifications at the second step below: 1> Query 'power1_alarm' attribute when the power capping occurs. 2> Query 'power1_alarm' attribute when the power capping is over and the current average power is less then power cap value. The root cause is that the resource->power_alarm is set to true at the first step. And power meter use this old value to show the power alarm state instead of the current the comparison value.

2025-03-02hwmon: (pmbus/core) Report content of CAPABILITY register in debugfsGuenter Roeck

2025-03-02hwmon: (pmbus/core) Optimize debugfs status attribute initializationGuenter Roeck
Define debugfs attributes used to access status registers in a data structure and loop through it instead of creating debugfs files one by one. This reduces code size and simplifies adding additional attributes if needed. Reviewed-by: Tzung-Bi Shih <tzungbi@kernel.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2025-03-02hwmon: (pmbus/core) Optimize debugfs block data attribute initializationGuenter Roeck
Define debugfs attributes which need block data access in a data structure and loop through it instead of creating debugfs files one by one. This reduces code size and simplifies adding additional attributes if needed. While this is currently only used for manufacturer specific attributes, the access code is generic and also works for other block attributes, so rename operation functions from _mfg to _block. While at it, rename the "revison" file to "pmbus_revision" to make its meaning more obvious and to create a clear distinction against the "mfg_revision" file.

2025-03-02hwmon: (pmbus/core) Make debugfs code unconditionalGuenter Roeck
Drop contitionals around debugfs code to compile it unconditionally. In practice it will be optimized away by the compiler if CONFIG_DEBUG_FS is not enabled, so the code size is not affected by this change. Also silently ignore errors if debugfs initialization fails.

2025-02-06hwmon: (xgene-hwmon) use appropriate type for the latency valueAndrey Vatoropin
The expression PCC_NUM_RETRIES * pcc_chan->latency is currently being evaluated using 32-bit arithmetic. Since a value of type 'u64' is used to store the eventual result, and this result is later sent to the function usecs_to_jiffies with input parameter unsigned int, the current data type is too wide to store the value of ctx->usecs_lat.

2025-02-01mm/hugetlb: fix hugepage allocation for interleaved memory nodesRitesh Harjani (IBM)
gather_bootmem_prealloc() assumes the start nid as 0 and size as num_node_state(N_MEMORY). That means in case if memory attached numa nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail to scan few of these nodes. Since memory attached numa nodes can be interleaved in any fashion, hence ensure that the current code checks for all numa node ids (.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that it can distributes all nr_node_ids among the these many no. threads. e.g. qemu cmdline ======================== numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20" mem_cmd="-object memory-backend-ram,id=mem1,size=16G" w/o this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): ========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 0 kB with this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): =========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 2 HugePages_Free: 2 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 2097152 kB Link: https://lkml.kernel.org/r/f8d8dad3a5471d284f54185f65d575a6aaab692b.1736592534.git.ritesh.list@gmail.com Fixes: b78b27d02930 ("hugetlb: parallelize 1G hugetlb initialization") Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Reported-by: Pavithra Prakash <pavrampu@linux.ibm.com> Suggested-by: Muchun Song <muchun.song@linux.dev> Tested-by: Sourabh Jain <sourabhjain@linux.ibm.com> Reviewed-by: Luiz Capitulino <luizcap@redhat.com> Acked-by: David Rientjes <rientjes@google.com> Cc: Donet Tom <donettom@linux.ibm.com> Cc: Gang Li <gang.li@linux.dev> Cc: Daniel Jordan <daniel.m.jordan@oracle.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2025-02-01mm: gup: fix infinite loop within __get_longterm_lockedZhaoyang Huang
We can run into an infinite loop in __get_longterm_locked() when collect_longterm_unpinnable_folios() finds only folios that are isolated from the LRU or were never added to the LRU. This can happen when all folios to be pinned are never added to the LRU, for example when vm_ops->fault allocated pages using cma_alloc() and never added them to the LRU. Fix it by simply taking a look at the list in the single caller, to see if anything was added.
