Pull timer updates from Thomas Gleixner: "Updates for timers, timekeeping and drivers: Core: - The timer_shutdown[_sync]() infrastructure: Tearing down timers can be tedious when there are circular dependencies to other things which need to be torn down. A prime example is timer and workqueue where the timer schedules work and the work arms the timer. What needs to prevented is that pending work which is drained via destroy_workqueue() does not rearm the previously shutdown timer. Nothing in that shutdown sequence relies on the timer being functional. The conclusion was that the semantics of timer_shutdown_sync() should be: - timer is not enqueued - timer callback is not running - timer cannot be rearmed Preventing the rearming of shutdown timers is done by discarding rearm attempts silently. A warning for the case that a rearm attempt of a shutdown timer is detected would not be really helpful because it's entirely unclear how it should be acted upon. The only way to address such a case is to add 'if (in_shutdown)' conditionals all over the place. This is error prone and in most cases of teardown not required all. - The real fix for the bluetooth HCI teardown based on timer_shutdown_sync(). A larger scale conversion to timer_shutdown_sync() is work in progress. - Consolidation of VDSO time namespace helper functions - Small fixes for timer and timerqueue Drivers: - Prevent integer overflow on the XGene-1 TVAL register which causes an never ending interrupt storm. - The usual set of new device tree bindings - Small fixes and improvements all over the place" * tag 'timers-core-2022-12-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits) dt-bindings: timer: renesas,cmt: Add r8a779g0 CMT support dt-bindings: timer: renesas,tmu: Add r8a779g0 support clocksource/drivers/arm_arch_timer: Use kstrtobool() instead of strtobool() clocksource/drivers/timer-ti-dm: Fix missing clk_disable_unprepare in dmtimer_systimer_init_clock() clocksource/drivers/timer-ti-dm: Clear settings on probe and free clocksource/drivers/timer-ti-dm: Make timer_get_irq static clocksource/drivers/timer-ti-dm: Fix warning for omap_timer_match clocksource/drivers/arm_arch_timer: Fix XGene-1 TVAL register math error clocksource/drivers/timer-npcm7xx: Enable timer 1 clock before use dt-bindings: timer: nuvoton,npcm7xx-timer: Allow specifying all clocks dt-bindings: timer: rockchip: Add rockchip,rk3128-timer clockevents: Repair kernel-doc for clockevent_delta2ns() clocksource/drivers/ingenic-ost: Define pm functions properly in platform_driver struct clocksource/drivers/sh_cmt: Access registers according to spec vdso/timens: Refactor copy-pasted find_timens_vvar_page() helper into one copy Bluetooth: hci_qca: Fix the teardown problem for real timers: Update the documentation to reflect on the new timer_shutdown() API timers: Provide timer_shutdown[_sync]() timers: Add shutdown mechanism to the internal functions timers: Split [try_to_]del_timer[_sync]() to prepare for shutdown mode ...

Pull irq updates from Thomas Gleixner: "Updates for the interrupt core and driver subsystem: The bulk is the rework of the MSI subsystem to support per device MSI interrupt domains. This solves conceptual problems of the current PCI/MSI design which are in the way of providing support for PCI/MSI[-X] and the upcoming PCI/IMS mechanism on the same device. IMS (Interrupt Message Store] is a new specification which allows device manufactures to provide implementation defined storage for MSI messages (as opposed to PCI/MSI and PCI/MSI-X that has a specified message store which is uniform accross all devices). The PCI/MSI[-X] uniformity allowed us to get away with "global" PCI/MSI domains. IMS not only allows to overcome the size limitations of the MSI-X table, but also gives the device manufacturer the freedom to store the message in arbitrary places, even in host memory which is shared with the device. There have been several attempts to glue this into the current MSI code, but after lengthy discussions it turned out that there is a fundamental design problem in the current PCI/MSI-X implementation. This needs some historical background. When PCI/MSI[-X] support was added around 2003, interrupt management was completely different from what we have today in the actively developed architectures. Interrupt management was completely architecture specific and while there were attempts to create common infrastructure the commonalities were rudimentary and just providing shared data structures and interfaces so that drivers could be written in an architecture agnostic way. The initial PCI/MSI[-X] support obviously plugged into this model which resulted in some basic shared infrastructure in the PCI core code for setting up MSI descriptors, which are a pure software construct for holding data relevant for a particular MSI interrupt, but the actual association to Linux interrupts was completely architecture specific. This model is still supported today to keep museum architectures and notorious stragglers alive. In 2013 Intel tried to add support for hot-pluggable IO/APICs to the kernel, which was creating yet another architecture specific mechanism and resulted in an unholy mess on top of the existing horrors of x86 interrupt handling. The x86 interrupt management code was already an incomprehensible maze of indirections between the CPU vector management, interrupt remapping and the actual IO/APIC and PCI/MSI[-X] implementation. At roughly the same time ARM struggled with the ever growing SoC specific extensions which were glued on top of the architected GIC interrupt controller. This resulted in a fundamental redesign of interrupt management and provided the today prevailing concept of hierarchical interrupt domains. This allowed to disentangle the interactions between x86 vector domain and interrupt remapping and also allowed ARM to handle the zoo of SoC specific interrupt components in a sane way. The concept of hierarchical interrupt domains aims to encapsulate the functionality of particular IP blocks which are involved in interrupt delivery so that they become extensible and pluggable. The X86 encapsulation looks like this: |--- device 1 [Vector]---[Remapping]---[PCI/MSI]--|... |--- device N where the remapping domain is an optional component and in case that it is not available the PCI/MSI[-X] domains have the vector domain as their parent. This reduced the required interaction between the domains pretty much to the initialization phase where it is obviously required to establish the proper parent relation ship in the components of the hierarchy. While in most cases the model is strictly representing the chain of IP blocks and abstracting them so they can be plugged together to form a hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the hardware it's clear that the actual PCI/MSI[-X] interrupt controller is not a global entity, but strict a per PCI device entity. Here we took a short cut on the hierarchical model and went for the easy solution of providing "global" PCI/MSI domains which was possible because the PCI/MSI[-X] handling is uniform across the devices. This also allowed to keep the existing PCI/MSI[-X] infrastructure mostly unchanged which in turn made it simple to keep the existing architecture specific management alive. A similar problem was created in the ARM world with support for IP block specific message storage. Instead of going all the way to stack a IP block specific domain on top of the generic MSI domain this ended in a construct which provides a "global" platform MSI domain which allows overriding the irq_write_msi_msg() callback per allocation. In course of the lengthy discussions we identified other abuse of the MSI infrastructure in wireless drivers, NTB etc. where support for implementation specific message storage was just mindlessly glued into the existing infrastructure. Some of this just works by chance on particular platforms but will fail in hard to diagnose ways when the driver is used on platforms where the underlying MSI interrupt management code does not expect the creative abuse. Another shortcoming of today's PCI/MSI-X support is the inability to allocate or free individual vectors after the initial enablement of MSI-X. This results in an works by chance implementation of VFIO (PCI pass-through) where interrupts on the host side are not set up upfront to avoid resource exhaustion. They are expanded at run-time when the guest actually tries to use them. The way how this is implemented is that the host disables MSI-X and then re-enables it with a larger number of vectors again. That works by chance because most device drivers set up all interrupts before the device actually will utilize them. But that's not universally true because some drivers allocate a large enough number of vectors but do not utilize them until it's actually required, e.g. for acceleration support. But at that point other interrupts of the device might be in active use and the MSI-X disable/enable dance can just result in losing interrupts and therefore hard to diagnose subtle problems. Last but not least the "global" PCI/MSI-X domain approach prevents to utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact that IMS is not longer providing a uniform storage and configuration model. The solution to this is to implement the missing step and switch from global PCI/MSI domains to per device PCI/MSI domains. The resulting hierarchy then looks like this: |--- [PCI/MSI] device 1 [Vector]---[Remapping]---|... |--- [PCI/MSI] device N which in turn allows to provide support for multiple domains per device: |--- [PCI/MSI] device 1 |--- [PCI/IMS] device 1 [Vector]---[Remapping]---|... |--- [PCI/MSI] device N |--- [PCI/IMS] device N This work converts the MSI and PCI/MSI core and the x86 interrupt domains to the new model, provides new interfaces for post-enable allocation/free of MSI-X interrupts and the base framework for PCI/IMS. PCI/IMS has been verified with the work in progress IDXD driver. There is work in progress to convert ARM over which will replace the platform MSI train-wreck. The cleanup of VFIO, NTB and other creative "solutions" are in the works as well.

Pull s390 updates from Alexander Gordeev: - Factor out handle_write() function and simplify 3215 console write operation - When 3170 terminal emulator is connected to the 3215 console driver the boot time could be very long due to limited buffer space or missing operator input. Add con3215_drop command line parameter and con3215_drop sysfs attribute file to instruct the kernel drop console data when such conditions are met - Fix white space errors in 3215 console driver - Move enum paiext_mode definition to a header file and rename it to paievt_mode to indicate this is now used for several events. Rename PAI_MODE_COUNTER to PAI_MODE_COUNTING to make consistent with PAI_MODE_SAMPLING - Simplify the logic of PMU pai_crypto mapped buffer reference counter and make it consistent with PMU pai_ext - Rename PMU pai_crypto mapped buffer structure member users to active_events to make it consistent with PMU pai_ext - Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option. This results in saving of 12K per 1M hugetlb page (~1.2%) and 32764K per 2G hugetlb page (~1.6%) - Use generic serial.h, bugs.h, shmparam.h and vga.h header files and scrap s390-specific versions - The generic percpu setup code does not expect the s390-like implementation and emits a warning. To get rid of that warning and provide sane CPU-to-node and CPU-to-CPU distance mappings implementat a minimal version of setup_per_cpu_areas() - Use kstrtobool() instead of strtobool() for re-IPL sysfs device attributes - Avoid unnecessary lookup of a pointer to MSI descriptor when setting IRQ affinity for a PCI device - Get rid of "an incompatible function type cast" warning by changing debug_sprintf_format_fn() function prototype so it matches the debug_format_proc_t function type - Remove unused info_blk_hdr__pcpus() and get_page_state() functions - Get rid of clang "unused unused insn cache ops function" warning by moving s390_insn definition to a private header - Get rid of clang "unused function" warning by making function raw3270_state_final() only available if CONFIG_TN3270_CONSOLE is enabled - Use kstrobool() to parse sclp_con_drop parameter to make it identical to the con3215_drop parameter and allow passing values like "yes" and "true" - Use sysfs_emit() for all SCLP sysfs show functions, which is the current standard way to generate output strings - Make SCLP con_drop sysfs attribute also writable and allow to change its value during runtime. This makes SCLP console drop handling consistent with the 3215 device driver - Virtual and physical addresses are indentical on s390. However, there is still a confusion when pointers are directly casted to physical addresses or vice versa. Use correct address converters virt_to_phys() and phys_to_virt() for s390 channel IO drivers - Support for power managemant has been removed from s390 since quite some time. Remove unused power managemant code from the appldata device driver - Allow memory tools like KASAN see memory accesses from the checksum code. Switch to GENERIC_CSUM if KASAN is enabled, just like x86 does - Add support of ECKD DASDs disks so it could be used as boot and dump devices - Follow checkpatch recommendations and use octal values instead of S_IRUGO and S_IWUSR for dump device attributes in sysfs - Changes to vx-insn.h do not cause a recompile of C files that use asm(".include \"asm/vx-insn.h\"\n") magic to access vector instruction macros from inline assemblies. Add wrapper include header file to avoid this problem - Use vector instruction macros instead of byte patterns to increase register validation routine readability - The current machine check register validation handling does not take into account various scenarios and might lead to killing a wrong user process or potentially ignore corrupted FPU registers. Simplify logic of the machine check handler and stop the whole machine if the previous context was kerenel mode. If the previous context was user mode, kill the current task - Introduce sclp_emergency_printk() function which can be used to emit a message in emergency cases. It is supposed to be used in cases where regular console device drivers may not work anymore, e.g. unrecoverable machine checks Keep the early Service-Call Control Block so it can also be used after initdata has been freed to allow sclp_emergency_printk() implementation - In case a system will be stopped because of an unrecoverable machine check error print the machine check interruption code to give a hint of what went wrong - Move storage error checking from the assembly entry code to C in order to simplify machine check handling. Enter the handler with DAT turned on, which simplifies the entry code even more - The machine check extended save areas are allocated using a private "nmi_save_areas" slab cache which guarantees a required power-of-two alignment.

Pull ARM SoC DT updates from Arnd Bergmann: "The devicetree changes contain exactly 1000 non-merge changesets, including a number of new arm64 SoC variants from Qualcomm and Apple, as well as the Renesas r9a07g043f/u chip in both arm64 and riscv variants. While we have occasionally merged support for non-arm SoCs in the past, this is now the normal path for riscv devicetree files. The most notable changes, by SoC platform, are: - The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips now have initial support. This is particularly nice as I am typing this on a T6002 Mac Studio with only a small number of driver patches. - Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662), SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670 (Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon 650) are all mobile phone chips that are closely related to others we already support. Adding those helps support more phones and we add several models from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3, 3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and Google (Pixel 3a). There are also new variants of the Herobrine and Trogdor chromebook motherboards. SA8540P is an automotive SoC used in the Qdrive-3 development platform - Rockchips gains no new SoC variants, but a lot of new boards: three mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two more Anbernic gaming systems based on RK3566 and a number of other RK356x based single-board computers. - Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as the newly added RZ/Five is based on the same design, this now gets reorganized in order to share most of the dts description between the two and add the RZ/Five SMARC EVK board support. Aside from that, there are the usual changes all over the tree: - New boards on other platforms contain two ASpeed BMC users, two Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based Kobo Aura2 ebook reader, two i.MX8 based development boards, two Uniphier Pro5 development boards, the STM32MP1 testbench board from DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek Helio X10 based Sony Xperia M5 phone. - The Starfive JH7100 source gets reorganized in order to support the VisionFive V1 board. - Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI, ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton, Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500, spear, ...

Pull slab updates from Vlastimil Babka: - SLOB deprecation and SLUB_TINY The SLOB allocator adds maintenance burden and stands in the way of API improvements [1]. Deprecate it by renaming the config option (to make users notice) to CONFIG_SLOB_DEPRECATED with updated help text. SLUB should be used instead as SLAB will be the next on the removal list. Based on reports from a riscv k210 board with 8MB RAM, add a CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the expense of scalability. This has resolved the k210 regression [2] so in case there are no others (that wouldn't be resolvable by further tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles. Existing defconfigs with CONFIG_SLOB are converted to CONFIG_SLUB_TINY. - kmalloc() slub_debug redzone improvements A series from Feng Tang that builds on the tracking or requested size for kmalloc() allocations (for caches with debugging enabled) added in 6.1, to make redzone checks consider the requested size and not the rounded up one, in order to catch more subtle buffer overruns. Includes new slub_kunit test. - struct slab fields reordering to accomodate larger rcu_head RCU folks would like to grow rcu_head with debugging options, which breaks current struct slab layout's assumptions, so reorganize it to make this possible. - Miscellaneous improvements/fixes: - __alloc_size checking compiler workaround (Kees Cook) - Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes) - Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina) - Correct SLUB's percpu allocation estimates (Baoquan He) - Re-enableS LUB's run-time failslab sysfs control (Alexander Atanasov) - Make tools/vm/slabinfo more user friendly when not run as root (Rong Tao) - Dead code removal in SLUB (Hyeonggon Yoo) * tag 'slab-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: (31 commits) mm, slob: rename CONFIG_SLOB to CONFIG_SLOB_DEPRECATED mm, slub: don't aggressively inline with CONFIG_SLUB_TINY mm, slub: remove percpu slabs with CONFIG_SLUB_TINY mm, slub: split out allocations from pre/post hooks mm/slub, kunit: Add a test case for kmalloc redzone check mm/slub, kunit: add SLAB_SKIP_KFENCE flag for cache creation mm, slub: refactor free debug processing mm, slab: ignore SLAB_RECLAIM_ACCOUNT with CONFIG_SLUB_TINY mm, slub: don't create kmalloc-rcl caches with CONFIG_SLUB_TINY mm, slub: lower the default slub_max_order with CONFIG_SLUB_TINY mm, slub: retain no free slabs on partial list with CONFIG_SLUB_TINY mm, slub: disable SYSFS support with CONFIG_SLUB_TINY mm, slub: add CONFIG_SLUB_TINY mm, slab: ignore hardened usercopy parameters when disabled slab: Remove special-casing of const 0 size allocations slab: Clean up SLOB vs kmalloc() definition mm/sl[au]b: rearrange struct slab fields to allow larger rcu_head mm/migrate: make isolate_movable_page() skip slab pages mm/slab: move and adjust kernel-doc for kmem_cache_alloc mm/slub, percpu: correct the calculation of early percpu allocation size ...

Pull printk updates from Petr Mladek: - Add NMI-safe SRCU reader API. It uses atomic_inc() instead of this_cpu_inc() on strong load-store architectures. - Introduce new console_list_lock to synchronize a manipulation of the list of registered consoles and their flags. This is a first step in removing the big-kernel-lock-like behavior of console_lock(). This semaphore still serializes console->write() calbacks against: - each other. It primary prevents potential races between early and proper console drivers using the same device. - suspend()/resume() callbacks and init() operations in some drivers. - various other operations in the tty/vt and framebufer susbsystems. It is likely that console_lock() serializes even operations that are not directly conflicting with the console->write() callbacks here. This is the most complicated big-kernel-lock aspect of the console_lock() that will be hard to untangle. - Introduce new console_srcu lock that is used to safely iterate and access the registered console drivers under SRCU read lock. This is a prerequisite for introducing atomic console drivers and console kthreads. It will reduce the complexity of serialization against normal consoles and console_lock(). Also it should remove the risk of deadlock during critical situations, like Oops or panic, when only atomic consoles are registered. - Check whether the console is registered instead of enabled on many locations. It was a historical leftover. - Cleanly force a preferred console in xenfb code instead of a dirty hack. - A lot of code and comment clean ups and improvements. * tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: (47 commits) printk: htmldocs: add missing description tty: serial: sh-sci: use setup() callback for early console printk: relieve console_lock of list synchronization duties tty: serial: kgdboc: use console_list_lock to trap exit tty: serial: kgdboc: synchronize tty_find_polling_driver() and register_console() tty: serial: kgdboc: use console_list_lock for list traversal tty: serial: kgdboc: use srcu console list iterator proc: consoles: use console_list_lock for list iteration tty: tty_io: use console_list_lock for list synchronization printk, xen: fbfront: create/use safe function for forcing preferred netconsole: avoid CON_ENABLED misuse to track registration usb: early: xhci-dbc: use console_is_registered() tty: serial: xilinx_uartps: use console_is_registered() tty: serial: samsung_tty: use console_is_registered() tty: serial: pic32_uart: use console_is_registered() tty: serial: earlycon: use console_is_registered() tty: hvc: use console_is_registered() efi: earlycon: use console_is_registered() tty: nfcon: use console_is_registered() serial_core: replace uart_console_enabled() with uart_console_registered() ...

Andi Kleen requested that we print the PID when the LOCK_MAND warning fires, to help track down applications trying to use it. Finally, we added some new warnings to some of the file locking functions that fire when the ->fl_file and filp arguments differ. This helped us find some long-standing bugs in lockd. Patches for those are in Chuck Lever's tree and should be in his v6.2 PR. After that patch, people using NFSv2/v3 locking may see some warnings fire until those go in. Happy Holidays!" * tag 'locks-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: Add process name and pid to locks warning nfsd: use locks_inode_context helper nfs: use locks_inode_context helper lockd: use locks_inode_context helper ksmbd: use locks_inode_context helper cifs: use locks_inode_context helper ceph: use locks_inode_context helper filelock: add a new locks_inode_context accessor function filelock: new helper: vfs_inode_has_locks filelock: WARN_ON_ONCE when ->fl_file and filp don't match

Merge tag 'unsigned-char-6.2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux Pull unsigned-char conversion from Jason Donenfeld: "Enable -funsigned-char and fix code affected by that flag. During the 6.1 cycle, several patches already made it into the tree, which were for code that was already broken on at least one architecture, where the naked char had a different sign than the code author anticipated, or were part of some bug fix for an existing bug that this initiative unearthed. These 6.1-era fixes are: 64806090 ("MIPS: pic32: treat port as signed integer") 5c26159c ("ipvs: use explicitly signed chars") e6cb8769 ("wifi: airo: do not assign -1 to unsigned char") 937ec9f7 ("staging: rtl8192e: remove bogus ssid character sign test") 67704738 ("misc: sgi-gru: use explicitly signed char") 50895a55 ("ALSA: rme9652: use explicitly signed char") ee03c0f2 ("ALSA: au88x0: use explicitly signed char") 835bed1b ("fbdev: sisfb: use explicitly signed char") 50f19697 ("parisc: Use signed char for hardware path in pdc.h") 66063033 ("wifi: rt2x00: use explicitly signed or unsigned types") Regarding patches in this pull: - There is one patch in this pull that should have made it to you during 6.1 ("media: stv0288: use explicitly signed char"), but the maintainer was MIA during the cycle, so it's in here instead. - Two patches fix single architecture code affected by unsigned char ("perf/x86: Make struct p4_event_bind::cntr signed array" and "sparc: sbus: treat CPU index as integer"), while one patch fixes an unused typedef, in case it's ever used in the future ("media: atomisp: make hive_int8 explictly signed"). - Finally, there's the change to actually enable -funsigned-char ("kbuild: treat char as always unsigned") and then the removal of some no longer useful !__CHAR_UNSIGNED__ selftest code ("lib: assume char is unsigned"). The various fixes were found with a combination of diffing objdump output, a large variety of Coccinelle scripts, and plain old grep. In the end, things didn't seem as bad as I feared they would. But of course, it's also possible I missed things. However, this has been in linux-next for basically an entire cycle now, so I'm not overly worried. I've also been daily driving this on my laptop for all of 6.1. Still, this series, and the ones sent for 6.1 don't total in quantity to what I thought it'd be, so I will be on the lookout for breakage. We could receive a few reports that are quickly fixable. Hopefully we won't receive a barrage of reports that would result in a revert. And just maybe we won't receive any reports at all and nobody will even notice.

Pull RCU updates from Paul McKenney: - Documentation updates. This is the second in a series from an ongoing review of the RCU documentation. - Miscellaneous fixes. - Introduce a default-off Kconfig option that depends on RCU_NOCB_CPU that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument CPU lists, causes call_rcu() to introduce delays. These delays result in significant power savings on nearly idle Android and ChromeOS systems. These savings range from a few percent to more than ten percent. This series also includes several commits that change call_rcu() to a new call_rcu_hurry() function that avoids these delays in a few cases, for example, where timely wakeups are required. Several of these are outside of RCU and thus have acks and reviews from the relevant maintainers. - Create an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe() for architectures that support NMIs, but which do not provide NMI-safe this_cpu_inc(). These NMI-safe SRCU functions are required by the upcoming lockless printk() work by John Ogness et al. - Changes providing minor but important increases in torture test coverage for the new RCU polled-grace-period APIs. - Changes to torturescript that avoid redundant kernel builds, thus providing about a 30% speedup for the torture.sh acceptance test. * tag 'rcu.2022.12.02a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: (49 commits) net: devinet: Reduce refcount before grace period net: Use call_rcu_hurry() for dst_release() workqueue: Make queue_rcu_work() use call_rcu_hurry() percpu-refcount: Use call_rcu_hurry() for atomic switch scsi/scsi_error: Use call_rcu_hurry() instead of call_rcu() rcu/rcutorture: Use call_rcu_hurry() where needed rcu/rcuscale: Use call_rcu_hurry() for async reader test rcu/sync: Use call_rcu_hurry() instead of call_rcu rcuscale: Add laziness and kfree tests rcu: Shrinker for lazy rcu rcu: Refactor code a bit in rcu_nocb_do_flush_bypass() rcu: Make call_rcu() lazy to save power rcu: Implement lockdep_rcu_enabled for !CONFIG_DEBUG_LOCK_ALLOC srcu: Debug NMI safety even on archs that don't require it srcu: Explain the reason behind the read side critical section on GP start srcu: Warn when NMI-unsafe API is used in NMI arch/s390: Add ARCH_HAS_NMI_SAFE_THIS_CPU_OPS Kconfig option arch/loongarch: Add ARCH_HAS_NMI_SAFE_THIS_CPU_OPS Kconfig option rcu: Fix __this_cpu_read() lockdep warning in rcu_force_quiescent_state() rcu-tasks: Make grace-period-age message human-readable ...
