Pull remoteproc updates from Bjorn Andersson: - Unnecessary type casts from the 'void *' rproc->priv pointer are dropped throughout the subsystem. - A kernel-doc error is corrected in the Mediatek SCPI IPI implementation - The firmware loading onto the IMX DSP remote processors is reworked to avoid non-32bit memory operations. A module parameter is introduced to assist development of firmware without communication abilities in place. Error paths in imx_dsp_rproc_mbox_alloc() is cleaned up - The cluster configuration handling in the TI K3 R5 driver is corrected and support for the single-R5 core found in the TI AM62x SoC family is introduced - The TI PRU driver device- to virtual-address translation is updated to avoid compiler warning about the unsigned device-address always being larger than 0 - The ST remoteproc driver is transitioned to use of_property_present() - Issues with kicks arriving after the STM32 remote processor has been shut down are mitigated by checking the processor's state before handling them. - Support for mailbox channels for communication with the remote processors are added to the Xilinx R5 remoteproc driver. The naming of carveouts are corrected and their parsing is reworked. For this a couple of fixes targeting the mailbox subsystem are picked up here as well. - Reference counting of of_nodes are corrected in the ST, STM32, RCAR and IMX remoteproc drivers * tag 'rproc-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (24 commits) remoteproc: st: Use of_property_present() for testing DT property presence dt-bindings: remoteproc: Drop unneeded quotes remoteproc: imx_dsp_rproc: Fix kernel test robot sparse warning remoteproc: imx_dsp_rproc: Improve exception handling in imx_dsp_rproc_mbox_alloc() remoteproc: pru: Remove always true check positive unsigned value dt-bindings: remoteproc: stm32-rproc: Typo fix remoteproc: stm32_rproc: Add mutex protection for workqueue remoteproc: Remove unnecessary (void*) conversions remoteproc: imx_dsp_rproc: Call of_node_put() on iteration error remoteproc: imx_rproc: Call of_node_put() on iteration error remoteproc: rcar_rproc: Call of_node_put() on iteration error remoteproc: st: Call of_node_put() on iteration error remoteproc: stm32: Call of_node_put() on iteration error remoteproc: k3-r5: Use separate compatible string for TI AM62x SoC family dt-bindings: remoteproc: ti: Add new compatible for AM62 SoC family remoteproc: k3-r5: Simplify cluster mode setting usage remoteproc/mtk_scpi_ipi: Fix one kernel-doc comment remoteproc: xilinx: Add mailbox channels for rpmsg drivers: remoteproc: xilinx: Fix carveout names mailbox: zynqmp: Fix typo in IPI documentation ...

Pull regmap updates from Mark Brown: "This is a much bigger change for regmap than is normal, the main things being the addition of some KUnit coverage and a maple tree based register cache which longer term is likely to replace the rbtree cache except possibly for very small register maps. While it's complete overkill for most applications the code for maple trees is there and there are some larger, sparser devices where the data structure is a better fit. The maple tree support is still a work in progress but already useful, there's some conversions of drivers ready to go after the merge window. Summary: - Support for shifting register addresses up as well as down, there's a use cases with memory mapped MDIO. - Refactoring of the type configuration in regmap-irq to allow access to driver data in the handler, needed by some GPIO devices. - Some initial KUnit coverage, the bulk of the driver facing API is covered but there's holes and things like the data marshalling for bytestream buses are just not covered in the slightest. - Removal of the compressed cache type, it had zero users and was getting in the way of KUnit. - Addition of a maple tree based register cache, there's more work to do but it's already useful for some devices with a flatter data structure than rbtree and getting to use all the optimisation work Liam is doing" * tag 'regmap-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: allow upshifting register addresses before performing operations regmap: Pass irq_drv_data as a parameter for set_type_config() regmap: Use mas_walk() instead of mas_find() regmap: Fix double unlock in the maple cache regmap: Add maple tree based register cache regmap: Factor out single value register syncing regmap: Add some basic kunit tests regmap: Add RAM backed register map regmap: Removed compressed cache support regmap: Support paging for buses with reg_read()/reg_write() regmap: Clarify error for unknown cache types regmap: Handle sparse caches in the default sync regmap: add a helper to translate the register address regmap: cache: Silence checkpatch warning regmap: cache: Return error in cache sync operations for REGCACHE_NONE regmap-irq: Place kernel doc of struct regmap_irq_chip in order regmap-irq: Add no_status support regmap: sdw: Remove 8-bit value size restriction regmap: sdw: Update misleading comment

Pull x86 APIC updates from Thomas Gleixner: - Fix the incorrect handling of atomic offset updates in reserve_eilvt_offset() The check for the return value of atomic_cmpxchg() is not compared against the old value, it is compared against the new value, which makes it two round on success. Convert it to atomic_try_cmpxchg() which does the right thing. - Handle IO/APIC less systems correctly When IO/APIC is not advertised by ACPI then the computation of the lower bound for dynamically allocated interrupts like MSI goes wrong. This lower bound is used to exclude the IO/APIC legacy GSI space as that must stay reserved for the legacy interrupts. In case that the system, e.g. VM, does not advertise an IO/APIC the lower bound stays at 0. 0 is an invalid interrupt number except for the legacy timer interrupt on x86. The return value is unchecked in the core code, so it ends up to allocate interrupt number 0 which is subsequently considered to be invalid by the caller, e.g. the MSI allocation code. A similar problem was already cured for device tree based systems years ago, but that missed - or did not envision - the zero IO/APIC case. Consolidate the zero check and return the provided "from" argument to the core code call site, which is guaranteed to be greater than 0. - Simplify the X2APIC cluster CPU mask logic for CPU hotplug Per cluster CPU masks are required for X2APIC in cluster mode to determine the correct cluster for a target CPU when calculating the destination for IPIs These masks are established when CPUs are borught up. The first CPU in a cluster must allocate a new cluster CPU mask. As this happens during the early startup of a CPU, where memory allocations cannot be done, the mask has to be allocated by the control CPU. The current implementation allocates a clustermask just in case and if the to be brought up CPU is the first in a cluster the CPU takes over this allocation from a global pointer. This works nicely in the fully serialized CPU bringup scenario which is used today, but would fail completely for parallel bringup of CPUs. The cluster association of a CPU can be computed from the APIC ID which is enumerated by ACPI/MADT. So the cluster CPU masks can be preallocated and associated upfront and the upcoming CPUs just need to set their corresponding bit. Aside of preparing for parallel bringup this is a valuable simplification on its own. - Remove global variables which control the early startup of secondary CPUs on 64-bit The only information which is needed by a starting CPU is the Linux CPU number. The CPU number allows it to retrieve the rest of the required data from already existing per CPU storage. So instead of initial_stack, early_gdt_desciptor and initial_gs provide a new variable smpboot_control which contains the Linux CPU number for now. The starting CPU can retrieve and compute all required information for startup from there. Aside of being a cleanup, this is also preparing for parallel CPU bringup, where starting CPUs will look up their Linux CPU number via the APIC ID, when smpboot_control has the corresponding control bit set. - Make cc_vendor globally accesible Subsequent parallel bringup changes require access to cc_vendor because confidental computing platforms need special treatment in the early startup phase vs. CPUID and APCI ID readouts. The change makes cc_vendor global and provides stub accessors in case that CONFIG_ARCH_HAS_CC_PLATFORM is not set. This was merged from the x86/cc branch in anticipation of further parallel bringup commits which require access to cc_vendor. Due to late discoveries of fundamental issue with those patches these commits never happened. The merge commit is unfortunately in the middle of the APIC commits so unraveling it would have required a rebase or revert. As the parallel bringup seems to be well on its way for 6.5 this would be just pointless churn. As the commit does not contain any functional change it's not a risk to keep it. * tag 'x86-apic-2023-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/ioapic: Don't return 0 from arch_dynirq_lower_bound() x86/apic: Fix atomic update of offset in reserve_eilvt_offset() x86/coco: Export cc_vendor x86/smpboot: Reference count on smpboot_setup_warm_reset_vector() x86/smpboot: Remove initial_gs x86/smpboot: Remove early_gdt_descr on 64-bit x86/smpboot: Remove initial_stack on 64-bit x86/apic/x2apic: Allow CPU cluster_mask to be populated in parallel

Pull timers and timekeeping updates from Thomas Gleixner: - Improve the VDSO build time checks to cover all dynamic relocations VDSO does not allow dynamic relocations, but the build time check is incomplete and fragile. It's based on architectures specifying the relocation types to search for and does not handle R_*_NONE relocation entries correctly. R_*_NONE relocations are injected by some GNU ld variants if they fail to determine the exact .rel[a]/dyn_size to cover trailing zeros. R_*_NONE relocations must be ignored by dynamic loaders, so they should be ignored in the build time check too. Remove the architecture specific relocation types to check for and validate strictly that no other relocations than R_*_NONE end up in the VSDO .so file. - Prefer signal delivery to the current thread for CLOCK_PROCESS_CPUTIME_ID based posix-timers Such timers prefer to deliver the signal to the main thread of a process even if the context in which the timer expires is the current task. This has the downside that it might wake up an idle thread. As there is no requirement or guarantee that the signal has to be delivered to the main thread, avoid this by preferring the current task if it is part of the thread group which shares sighand. This not only avoids waking idle threads, it also distributes the signal delivery in case of multiple timers firing in the context of different threads close to each other better. - Align the tick period properly (again) For a long time the tick was starting at CLOCK_MONOTONIC zero, which allowed users space applications to either align with the tick or to place a periodic computation so that it does not interfere with the tick. The alignement of the tick period was more by chance than by intention as the tick is set up before a high resolution clocksource is installed, i.e. timekeeping is still tick based and the tick period advances from there. The early enablement of sched_clock() broke this alignement as the time accumulated by sched_clock() is taken into account when timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is not longer a multiple of tick periods, which breaks applications which relied on that behaviour. Cure this by aligning the tick starting point to the next multiple of tick periods, i.e 1000ms/CONFIG_HZ. - A set of NOHZ fixes and enhancements: * Cure the concurrent writer race for idle and IO sleeptime statistics The statitic values which are exposed via /proc/stat are updated from the CPU local idle exit and remotely by cpufreq, but that happens without any form of serialization. As a consequence sleeptimes can be accounted twice or worse. Prevent this by restricting the accumulation writeback to the CPU local idle exit and let the remote access compute the accumulated value. * Protect idle/iowait sleep time with a sequence count Reading idle/iowait sleep time, e.g. from /proc/stat, can race with idle exit updates. As a consequence the readout may result in random and potentially going backwards values. Protect this by a sequence count, which fixes the idle time statistics issue, but cannot fix the iowait time problem because iowait time accounting races with remote wake ups decrementing the remote runqueues nr_iowait counter. The latter is impossible to fix, so the only way to deal with that is to document it properly and to remove the assertion in the selftest which triggers occasionally due to that. * Restructure struct tick_sched for better cache layout * Some small cleanups and a better cache layout for struct tick_sched - Implement the missing timer_wait_running() callback for POSIX CPU timers For unknown reason the introduction of the timer_wait_running() callback missed to fixup posix CPU timers, which went unnoticed for almost four years. While initially only targeted to prevent livelocks between a timer deletion and the timer expiry function on PREEMPT_RT enabled kernels, it turned out that fixing this for mainline is not as trivial as just implementing a stub similar to the hrtimer/timer callbacks. The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled systems there is a livelock issue independent of RT. CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU timers out from hard interrupt context to task work, which is handled before returning to user space or to a VM. The expiry mechanism moves the expired timers to a stack local list head with sighand lock held. Once sighand is dropped the task can be preempted and a task which wants to delete a timer will spin-wait until the expiry task is scheduled back in. In the worst case this will end up in a livelock when the preempting task and the expiry task are pinned on the same CPU. The timer wheel has a timer_wait_running() mechanism for RT, which uses a per CPU timer-base expiry lock which is held by the expiry code and the task waiting for the timer function to complete blocks on that lock. This does not work in the same way for posix CPU timers as there is no timer base and expiry for process wide timers can run on any task belonging to that process, but the concept of waiting on an expiry lock can be used too in a slightly different way. Add a per task mutex to struct posix_cputimers_work, let the expiry task hold it accross the expiry function and let the deleting task which waits for the expiry to complete block on the mutex. In the non-contended case this results in an extra mutex_lock()/unlock() pair on both sides. This avoids spin-waiting on a task which is scheduled out, prevents the livelock and cures the problem for RT and !RT systems * tag 'timers-core-2023-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: posix-cpu-timers: Implement the missing timer_wait_running callback selftests/proc: Assert clock_gettime(CLOCK_BOOTTIME) VS /proc/uptime monotonicity selftests/proc: Remove idle time monotonicity assertions MAINTAINERS: Remove stale email address timers/nohz: Remove middle-function __tick_nohz_idle_stop_tick() timers/nohz: Add a comment about broken iowait counter update race timers/nohz: Protect idle/iowait sleep time under seqcount timers/nohz: Only ever update sleeptime from idle exit timers/nohz: Restructure and reshuffle struct tick_sched tick/common: Align tick period with the HZ tick. selftests/timers/posix_timers: Test delivery of signals across threads posix-timers: Prefer delivery of signals to the current thread vdso: Improve cmd_vdso_check to check all dynamic relocations

Pull core debugobjects update from Thomas Gleixner: "A single update to debugobjects: Prevent a race vs statically initialized objects. Such objects are usually not initialized via an init() function. They are special cased and detected on first use under the assumption that they are already correctly initialized via the static initializer. This works correctly unless there are two concurrent debug object operations on such an object. The first one detects that the object is not yet tracked and tries to establish a tracking object after dropping the debug objects hash bucket lock. The concurrent operation does the same. The one which wins the race ends up modifying the state of the object which makes the other one fail resulting in a bogus debug objects warning. Prevent this by making the detection of a static object and the allocation of a tracking object atomic under the hash bucket lock. So the first one to acquire the hash bucket lock will succeed and the second one will observe the correct tracking state. This race existed forever but was only exposed when the timer wheel code added a debug_object_assert_init() call outside of the timer base locked region. This replaced the previous warning about timer::function being NULL which had to be removed when the timer_shutdown() mechanics were added" * tag 'core-debugobjects-2023-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: debugobject: Prevent init race with static objects

Pull x86 SEV updates from Borislav Petkov: - Add the necessary glue so that the kernel can run as a confidential SEV-SNP vTOM guest on Hyper-V.

devm_clk_get() will return either an error or NULL, which the driver handles, continuing to use the clock of reading the value of the clock-frequency property. However, the value of ov5670->xvclk is left as-is and the other clock framework functions aren't capable of handling error values. Use devm_clk_get_optional() to obtain NULL instead of -ENOENT.
