2026-07-15docs: pagemap: fix flags location, member name and sample codeZenghui Yu1-4/+4
The userland visible page flags (KPF_*) were initially moved to include/linux/kernel-page-flags.h in commit 1a9b5b7fe0c5 ("mm: export stable page flags"), and later moved to include/uapi/linux/kernel-page-flags.h in commit 607ca46e97a1 ("UAPI: (Scripted) Disintegrate include/linux"). Update the doc to reflect the current location of these flags. The member @walk_end of struct pm_scan_arg {} was wrongly written as "end_walk". The first sample code of the PAGEMAP_SCAN ioctl wrongly used the PM_SCAN_CHECK_WPASYNC flag twice, instead of the PM_SCAN_WP_MATCHING flag. The second one included the wrong category in the required mask - PAGE_IS_FILE should be used instead of PAGE_IS_SWAPPED as per the intention. Fix them all together.

2026-07-15irqchip/gic-v3: Add Renesas R-Car Gen4 erratum workaroundMarek Vasut1-0/+1
Renesas R-Car S4/V4H/V4M GIC600 integration has address width for AXI or APB interface configured to 32 bit, it can therefore access only the first 4 GiB of physical address space. This information comes from R-Car V4H Interface Specification sheet; there is currently no technical update number assigned to this limitation. Further input from hardware engineer indicates that this limitation also applies to R-Car S4 and V4M. Name the limitation GEN4GICITS1, and add a driver quirk to mitigate this limitation. The quirk is keyed on the combination of the GIC implementation and the platform identification in the device tree.

2026-07-14tracing/probes: Add this_cpu_read() and this_cpu_ptr() dereference method to ↵Masami Hiramatsu (Google)2-0/+4
fetcharg When tracing the kernel local variables, sometimes we need to get the CPU local variables. To access it, current simple dereference is not enough. Thus, introduce a special this_cpu_read() dereference to access per-cpu variable for the current CPU (accessing other CPU variable may race with updates on other CPUs). Also this_cpu_ptr() is for accessing per-cpu pointer. Those are working as same as the kernel percpu macro.

Since we can use the BTF to cast value to a structure pointer type, it is useful to introduce "$current" special variable support to fetcharg. User can define a fetcharg to access current task_struct properties using BTF info. e.g. $current->cpus_ptr Link: https://lore.kernel.org/all/178271366709.1176915.15320906169981578568.stgit@devnote2/ Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org>
2026-07-14tracing/probes: Support field specifier option for typecastMasami Hiramatsu (Google)3-7/+14
Add a field specifier option for the typecast. This works like container_of() macro. (STRUCT[,FIELD[.FIELD2...]])VAR This is equivalent to : container_of(VAR, struct STRUCT, FIELD[.FIELD2...]) For example: echo "f tick_nohz_handler next_tick=(tick_sched,sched_timer)timer->next_tick" >> dynamic_events This will trace tick_nohz_handler() with its tick_sched::next_tick which is converted from @timer by contianer_of(tick, struct tick_sched, sched_timer). So, if you enabkle both fprobes:tick_nohz_handler__entry and timer:hrtimer_expire_entry events, we will see something like: <idle>-0 [002] d.h1. 3778.087272: hrtimer_expire_entry: hrtimer=00000000d63db328 f unction=tick_nohz_handler now=3777450051040 <idle>-0 [002] d.h1. 3778.087281: tick_nohz_handler__entry: (tick_nohz_handler+0x4 /0x140) next_tick=3777450000000 Link: https://lore.kernel.org/all/178271365745.1176915.725923927180862257.stgit@devnote2/ Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org>
2026-07-14tracing/probes: Support nested typecastMasami Hiramatsu (Google)3-0/+6
When we hit an open parenthesis right after typecast closing parenthesis, it means we have nested typecast. This allows us to typecast a generic data member in a structure to a pointer to another structure. For example, to cast a DATA_MEMBER of VAR structure to STRUCT pointer and get MEMBER value. (STRUCT)(VAR->DATA_MEMBER)->MEMBER Also, we can nest typecast. (STRUCT1)((STRUCT2)$ARG->FIELD2)->FIELD1 Currently the max nest level is limited to 3. This also allows user to use typecasting for registers or stacks on kprobe events. e.g. (STRUCT)(%ax)->MEMBER (STRUCT)($stack0)->MEMBER Link: https://lore.kernel.org/all/178271363855.1176915.16793301788257446529.stgit@devnote2/ Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org>

Support BTF typecast feature on other probe events, but only if it is kernel function entry or return, and must use function parameter name or $retval. This means you can do: (STRUCT)PARAM->MEMBER Note: you can not use other variables like $stackN, %reg etc. That needs nesting support. To support other probe events, we just need to use last_struct type when we find a function parameter in parse_btf_arg(). This also updates <tracefs>/README file to show struct typecast.

2026-07-14dt-bindings: soc: mediatek: mutex: Improve title and descriptionAngeloGioacchino Del Regno1-7/+10
Improve both the title and the description of this hardware to disambiguate its functionality from a hardware mutex and/or from a hwspinlock. Though in datasheets this is called "DISP_MUTEX", the meaning is is "Mute-X" (where "X" means "any hardware trigger signal") really as this is what this piece of hardware does: muting or unmuting of signals in each sub-IP of the display or other multimedia related controllers. Based on that, also clarify the description text, as to make sure that the information is actually accurate. While at it, also avoid forcing literal blocks in the description as there is nothing in there needing that (no ascii graph or other stuff that needs a literal block anyway), and add myself in the list of maintainers.

2026-07-13x86/alternative: Drop smp_locks glueBorislav Petkov (AMD)1-3/+0
This was there to be able to patch out locking instructions when running a SMP kernel build on a UP CPU. The times are long gone when single-CPU x86 machines were relevant so drop that machinery and simplify the code considerably. LOCK_PREFIX needs to stay for when one wants to do a UP build for whatever reason. That'll go away when CONFIG_SMP becomes unconditional. Kill a bunch of leftover, unused prototypes while at it.

2026-07-13dt-bindings: firmware: qcom,scm: Add minidump SRAM propertyMukesh Ojha1-0/+7
On Qualcomm SoCs that support minidump, a word in always-on SRAM is shared between the Operating System(HLOS) and boot firmware. OS is expected to select the minidump download destination either USB upload to a host PC or save to on-device storage. Boot firmware will reads this word before DDR is initialized on the warm reset following a crash to decide where to deliver the minidump. Add a 'sram' property to the SCM binding to allow the OS to identify this SRAM region via a phandle.

2026-07-13ASoC: apple: mca: support simultaneous I2S capture on the frontendMark Brown6-204/+218
James Calligeros <jcalligeros99@gmail.com> says: This series introduces a number of changes to the ASoC driver for the Apple MCA peripheral to enable support for bidirectional I2S. This is achieved by allowing frontends to act as clock consumers and logically ORing data input lines when multiple backends are linked to a frontend. This allows the Texas Instruments speaker amps used on Apple Silicon Macs (Apple-specific revisions of TAS2764 and TAS2770) to send their IVSENSE data back to the SoC. Since these amps do not have any sort of integrated speaker protection logic, we must use the IVSENSE data and the Thiele/Small Parameters of the attached speaker(s) to implement our own in software.

Add the compatible for the MMC controllers of the Rockchip RV1106, which are compatible with the RK3288 variant. Unlike the newer controller in the RV1103B, which uses the RK3576 fallback, the RV1106 controller is the older IP whose drive and sample phases are set through clocks provided by the GRF, so the RK3288 fallback is the correct one here.
