2026-02-23platform/x86: alienware-wmi-wmax: Add G-Mode support to m18 laptopsKurt Borja1-1/+1

2026-02-23platform/x86: hp-wmi: add Omen 14-fb1xxx (board 8E41) supportAnton Plotnikov1-0/+1
Reverse engineering of the HP Omen Windows utility shows that for performance mode it uses the same codes listed in hp_thermal_profile_omen_v1. Therefore it seems sufficient to add the board model name to omen_thermal_profile_boards. Tested on Omen 14-fb1xxx: CPU power in performance profile reaches the Windows limit (65W), instead of 45W in automatic BIOS mode. Max fan speed was reached as well.

2026-02-23platform/x86: hp-wmi: Add Victus 16-d0xxx supportVictor Lattaro Volpini1-1/+2
This patch enables Victus thermal profile support for the HP Victus 16-d0xxx. It does so by adding model's DMI board name 88F8 to victus_thermal_profile_boards. Tested on a Victus 16-d0xxx: - Victus thermal profile choices available (quiet, balanced, performance) instead of the default ones (cool, quiet, balanced, performance); - Profile switching works correctly; - About 4% increase in FPS using benchmark Cyberpunk 2077 on performance profile; - No noticeable regressions.

2026-02-23platform/x86: intel-hid: Enable 5-button array on ThinkPad X1 Fold 16 Gen 1Leif Skunberg1-0/+7
The Lenovo ThinkPad X1 Fold 16 Gen 1 has physical volume up/down buttons that are handled through the intel-hid 5-button array interface. The firmware does not advertise 5-button array support via HEBC, so the driver relies on a DMI allowlist to enable it. Add the ThinkPad X1 Fold 16 Gen 1 to the button_array_table so the volume buttons work out of the box.

2026-02-23platform/x86: int3472: Handle GPIO type 0x10 (DOVDD)Leif Skunberg2-2/+10
The Lenovo ThinkPad X1 Fold 16 Gen 1 has an OV5675 sensor (ACPI HID OVTI5675) behind an INT3472 discrete PMIC controller. The INT3472 _DSM returns GPIO type 0x10 for one of the pins, which controls the DOVDD (digital I/O power) regulator enable. Type 0x10 is not currently handled by the driver, causing the GPIO to be ignored with a warning. Add INT3472_GPIO_TYPE_DOVDD (0x10) and handle it as a regulator with con_id "dovdd" to match the supply name used by sensor drivers (e.g. ov5675). Also increase GPIO_SUPPLY_NAME_LENGTH from 5 to 6 to accommodate the "dovdd" name (5 chars + null terminator).

2026-02-22Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds826-2422/+1211
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface.

2026-02-22Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds6673-13013/+13013
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-22add default_gfp() helper macro and use it in the new *alloc_obj() helpersLinus Torvalds2-24/+28
Most simple allocations use GFP_KERNEL, and with the new allocation helpers being introduced, let's just take advantage of that to simplify that default case. It's a numbers game: git grep 'alloc_obj(' | sed 's/.*\(GFP_[_A-Z]*\).*/\1/' | sort | uniq -c | sort -n | tail shows that about 90% of all those new allocator instances just use that standard GFP_KERNEL. Those helpers are already macros, and we can easily just make it be the default case when the gfp argument is missing. And yes, we could do that for all the legacy interfaces too, but let's keep it to just the new ones at least for now, since those all got converted recently anyway, so this is not any "extra" noise outside of that limited conversion. And, in fact, I want to do this before doing the -rc1 release, exactly so that we don't get extra merge conflicts. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-22slab.h: disable completely broken overflow handling in flex allocationsLinus Torvalds2-6/+2
Commit 69050f8d6d07 ("treewide: Replace kmalloc with kmalloc_obj for non-scalar types") started using the new allocation helpers, and in the process showed that they were completely non-working. The overflow logic in overflows_flex_counter_type() is completely the wrong way around, and that broke __alloc_flex() completely. By chance, the resulting code was then such a mess that clang generated sufficiently garbage code that objtool warned about it all. Which made it somewhat quicker to narrow things down. While fixing overflows_flex_counter_type() would presumably fix this all, I'm excising the whole broken overflow logic from __alloc_flex(), because we don't want that kind of code in basic allocation functions anyway. That (no longer) broken overflows_flex_counter_type() thing needs to be inserted into the actual __set_flex_counter() logic in the unlikely case that we ever want this at all. And made conditional.

2026-02-21scripts: coccicheck: warn on unset debug fileBenjamin Philip1-0/+5
coccicheck prints debug logs to stdout unless a debug file has been set. This makes it hard to read coccinelle's suggested changes, especially for someone new to coccicheck. From this commit, we warn about this behaviour from within the script on an unset debug file. Explicitly setting the debug file to /dev/null suppresses the warning while keeping the default.

2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook8016-20913/+20055
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2026-02-21tools/sched_ext: fix getopt not re-parsed on restartDavid Carlier6-0/+6
After goto restart, optind retains its advanced position from the previous getopt loop, causing getopt() to immediately return -1. This silently drops all command-line options on the restarted skeleton. Reset optind to 1 at the restart label so options are re-parsed. Affected schedulers: scx_simple, scx_central, scx_flatcg, scx_pair, scx_sdt, scx_cpu0. Signed-off-by: David Carlier <devnexen@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2026-02-21tools/sched_ext: scx_userland: fix data races on shared countersDavid Carlier1-13/+13
The stats thread reads nr_vruntime_enqueues, nr_vruntime_dispatches, nr_vruntime_failed, and nr_curr_enqueued concurrently with the main thread writing them, with no synchronization. Use __atomic builtins with relaxed ordering for all accesses to these counters to eliminate the data races. Only display accuracy is affected, not scheduling correctness.
