Similar in nature to ab10727. glibc-2.42 drops the legacy termio struct, but the ioctls.h header still defines some TC* constants in terms of termio (via sizeof). Hardcode the values instead. This fixes building Python for example, which falls over like: ./Modules/termios.c:1119:16: error: invalid application of 'sizeof' to incomplete type 'struct termio' Link: https://bugs.gentoo.org/961769 Link: https://bugs.gentoo.org/962600 Co-authored-by: Stian Halseth <stian@itx.no> Cc: stable@vger.kernel.org Signed-off-by: Sam James <sam@gentoo.org> Signed-off-by: Helge Deller <deller@gmx.de>
The "transitional" symbol keyword, while working with the "olddefconfig" target, was prompting during "oldconfig". This occurred because these symbols were not being marked as user-defined when they received values from transitional symbols that had user values. The "olddefconfig" target explicitly doesn't prompt for anything, so this deficiency wasn't noticed. The issue manifested when a symbol's value came from a transitional symbol's user value but the receiving symbol wasn't marked with SYMBOL_DEF_USER. Thus the "oldconfig" logic would then prompt for these symbols unnecessarily. Check after value calculation whether a symbol without a user value gets its value from a single transitional symbol that does have a user value. In such cases, mark the receiving symbol as user-defined to prevent prompting. Update regression tests to verify that symbols with transitional defaults are not prompted in "oldconfig", except when conditional defaults evaluate to 'no' and should legitimately be prompted. Build tested with "make testconfig".

pm_runtime_get_sync() and pm_runtime_put_autosuspend() were previously
called in cmdq_mbox_send_data(), which is under a spinlock in msg_submit()
(mailbox.c). This caused lockdep warnings such as "sleeping function
called from invalid context" when running with lockdebug enabled.

…l/git/clk/linux Pull clk updates from Stephen Boyd: "There's a bunch of patches here across drivers/clk/ to migrate drivers to use struct clk_ops::determine_rate() instead of the round_rate() one so that we can remove the round_rate clk_op entirely. Brian has taken up that task which nobody else has wanted to do for close to a decade. Thanks Brian! This is all prerequisite work to get to the real task of improving the clk rate setting process. Once we have determine_rate() used everywhere, we'll be able to do things like chain the rate request structs in linked lists to order the rate setting operations or add more parameters without having to change every clk driver in existence. It's also nice to not have multiple ways to do something which just causes confusion for clk driver authors. Overall I'm glad this is getting done. Beyond this change we also have a tweak to the clk_lookup() function in the core framework to use hashing on the clk name instead of a clk tree walk with string comparisons. We _still_ rely on the clk name to be unique, because historically we've used globally unique strings to describe the clk tree topology. This tree walk becomes increasingly slow as more clks are added to the system. Searching from the roots for a duplicate is simple but pretty dumb and it wastes boot time so we're using a hash table as an improvement. Ideally we wouldn't rely on the strings to be unique at all, relegating them to simply debug information, but that is future work that will likely require some sort of Kconfig knob indicating strings aren't used for topology description. Outside of the core framework changes we have the usual new SoC support and fixes to clk drivers for things that were discovered once the clks were used by consumer drivers. Nothing in particular is jumping out at me in the "misc" pile, except maybe the Amlogic driver that has gone through a refactoring. That series got a fix from testing in -next though so it seems likely that things have been getting good test coverage for a couple weeks already" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (299 commits) clk: microchip: core: remove duplicate roclk_determine_rate() reset: aspeed: register AST2700 reset auxiliary bus device dt-bindings: clock: ast2700: modify soc0/1 clock define clk: tegra: do not overallocate memory for bpmp clocks clk: ep93xx: Use int type to store negative error codes clk: nxp: Fix pll0 rate check condition in LPC18xx CGU driver clk: loongson2: Add clock definitions for Loongson-2K0300 SoC clk: loongson2: Avoid hardcoding firmware name of the reference clock clk: loongson2: Allow zero divisors for dividers clk: loongson2: Support scale clocks with an alternative mode clk: loongson2: Allow specifying clock flags for gate clock dt-bindings: clock: loongson2: Add Loongson-2K0300 compatible clk: clocking-wizard: Fix output clock register offset for Versal platforms clk: xilinx: Optimize divisor search in clk_wzrd_get_divisors_ver() clk: mmp: pxa1908: Instantiate power driver through auxiliary bus clk: s2mps11: add support for S2MPG10 PMIC clock dt-bindings: clock: samsung,s2mps11: add s2mpg10 dt-bindings: stm32: cosmetic fixes for STM32MP25 clock and reset bindings clk: stm32: introduce clocks for STM32MP21 platform dt-bindings: stm32: add STM32MP21 clocks and reset bindings ...

Pull more power management updates from Rafael Wysocki:
"These are cpufreq fixes and cleanups on top of the material merged
previously, a power management core code fix and updates of the
runtime PM framework including unit tests, documentation updates and
introduction of auto-cleanup macros for runtime PM "resume and get"

Specifics:
- Make cpufreq drivers setting the default CPU transition latency to
CPUFREQ_ETERNAL specify a proper default transition latency value
instead which addresses a regression introduced during the 6.6
cycle that broke CPUFREQ_ETERNAL handling (Rafael Wysocki)
- Make the cpufreq CPPC driver use a proper transition delay value
when CPUFREQ_ETERNAL is returned by cppc_get_transition_latency()
to indicate an error condition (Rafael Wysocki)
- Make cppc_get_transition_latency() return a negative error code to
indicate error conditions instead of using CPUFREQ_ETERNAL for this
purpose and drop CPUFREQ_ETERNAL that has no other users (Rafael
Wysocki, Gopi Krishna Menon)
- Fix device leak in the mediatek cpufreq driver (Johan Hovold)
- Set target frequency on all CPUs sharing a policy during frequency
updates in the tegra186 cpufreq driver and make it initialize all
cores to max frequencies (Aaron Kling)
- Rust cpufreq helper cleanup (Thorsten Blum)
- Make pm_runtime_put*() family of functions return 1 when the given
device is already suspended which is consistent with the
documentation (Brian Norris)
- Add basic kunit tests for runtime PM API contracts and update
return values in kerneldoc comments for the runtime PM API (Brian
Norris, Dan Carpenter)
- Add auto-cleanup macros for runtime PM "resume and get" and "get
without resume" operations, use one of them in the PCI core and
drop the existing "free" macro introduced for similar purpose, but
somewhat cumbersome to use (Rafael Wysocki)
- Make the core power management code avoid waiting on device links
marked as SYNC_STATE_ONLY which is consistent with the handling of
those device links elsewhere (Pin-yen Lin)"

Commit 27758d8 ("kbuild: enable -Werror for hostprogs") unconditionally enabled -Werror for the compiler, assembler, and linker when building the host programs, as the build footprint of the host programs is small (thus risk of build failures from warnings are low) and that stage of the build may not have Kconfig values (thus CONFIG_WERROR could not be used as a precondition). While turning warnings into errors unconditionally happens in a few places within the kernel, it can be disruptive to people who may be building with newer compilers, such as while doing a bisect. While it is possible to avoid this behavior by passing HOSTCFLAGS=-w or HOSTCFLAGS=-Wno-error, it may not be the most intuitive for regular users not intimately familiar with Kbuild. Avoid being disruptive to the entire build by depending on the explicit opt-in of CONFIG_WERROR or W=e to enable -Werror and the like while building the host programs. While this means there is a small portion of the build that does not have -Werror enabled (namely scripts/kconfig/* and scripts/basic/fixdep), it is better than not having it altogether.

The problem is that __kmem_cache_release() could be called from
do_kmem_cache_create() before init_kmem_cache_cpus() registers
the lockdep key.
Let's perform lockdep_unregister_key() only when init_kmem_cache_cpus()

SCL_SCALER_ENABLE can be used to enable/disable the scaler on DCE6. Program it to 0 when scaling isn't used, 1 when used. Additionally, clear some other registers when scaling is disabled and program the SCL_UPDATE register as recommended. This fixes visible glitches for users whose BIOS sets up a mode with scaling at boot, which DC was unable to clean up.

If mmap write lock is taken while draining retry fault, mmap write lock is not released because svm_range_restore_pages calls mmap_read_unlock then returns.

Currently, we use predefined snd_soc_acpi_link_adr tables to match the link adr from ACPI table to select the machine driver and the topology. However, with the mechanism, we need to create the snd_soc_acpi_link_adr table for each audio config. The sof_sdw machine driver is used by almost all Intel platforms with SOF and we can load required topology file dynamically today. In other words, we can use sof_sdw machine driver as the default machine driver for Intel SOF SoundWire codecs and no need to create snd_soc_acpi_link_adr table for every new audio configs. To achieve it, we need to drop the const for some members and edit the link adr and acpi adr data to match the data from the ACPI table.

Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. system_wq is a per-CPU worqueue, replaced by system_percpu_wq. Despite that, system_wq in this change has been replaced by system_dfl_wq, because there aren't per-cpu variables. The old wq will be kept for a few release cylces.

Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>: Currently, we create a ACPI mach table for every new audio configuration. And all Intel SOF SoundWire configurations point to the same sof_sdw machine driver. Also, we don't need a specific topology for a coufguration, we can use the function topology instead. That give us a change to generate an ACPI mach table based on the SoundWire codec information reported by the ACPI table and use the sof_sdw machine driver as the default machine driver. This will reduce the effort to support a new Intel SOF SoundWire audio configuration.
