PMU, P being power, support for the JH7110. PMIC and frequency scaling support for the JH7110 equipped VisionFive 2. Most of the DT bits for the JH7110, and the SBCs using it, are pending support for one of the clock controllers, so it's a smaller set of changes than I would have hoped for. Misc: Pick up some dt-binding cleanup that Palmer assigned to me & had no uptake from the respective maintainers. My powers of estimation failed me again, with part of my motivation for picking them up being the addition of new platforms that ended up not making it. Hopefully next window for those, as they were relatively close. Exclude the Allwinner and Renesas subdirectories from the Misc. MAINTAINERS entry, since I do not take care of those.

2023-06-20arm64: dts: exynos: Remove clock from Exynos850 pmu_system_controllerSam Protsenko
As described in the corresponding binding documentation for "samsung,exynos850-pmu", the "clocks" property should be used for specifying CLKOUT mux inputs. Therefore, the clock provided to exynos850 pmu_system_controller is incorrect and should be removed. Instead of making syscon regmap keep that clock running for PMU accesses, it should be made always running in the clock driver, because the kernel is not the only software accessing PMU registers on Exynos850 platform.

2023-06-20uml: Replace strlcpy with strscpyAzeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

2023-06-20s390/module: fix rela calculation for R_390_GOTENTSumanth Korikkar
During module load, module layout allocation occurs by initially allowing the architecture to frob the sections. This is performed via module_frob_arch_sections(). However, the size of each module memory types like text,data,rodata etc are updated correctly only after layout_sections(). After calculation of required module memory sizes for each types, move_module() is responsible for allocating the module memory for each type from modules vaddr range. Considering the sequence above, module_frob_arch_sections() updates the module mod_arch_specific got_offset before module memory text type size is fully updated in layout_sections(). Hence mod_arch_specific got_offset points to currently zero. As per s390 ABI, R_390_GOTENT : (G + O + A - P) >> 1 where G=me->mem[MOD_TEXT].base+me->arch.got_offset O=info->got_offset A=rela->r_addend P=loc fix R_390_GOTENT calculation in apply_rela(). Note: currently this doesn't break anything because me->arch.got_offset is zero. However, reordering of functions in the future could break it.

2023-06-20s390/kasan: avoid short by one page shadow memoryAlexander Gordeev
Kernel Address Sanitizer uses 3 bits per byte to encode memory. That is the number of bits the start and end address of a memory range is shifted right when the corresponding shadow memory is created for that memory range. The used memory mapping routine expects page-aligned addresses, while the above described 3-bit shift might turn the shadow memory range start and end boundaries into non-page-aligned in case the size of the original memory range is less than (PAGE_SIZE << 3). As result, the resulting shadow memory range could be short on one page. Align on page boundary the start and end addresses when mapping a shadow memory range and avoid the described issue in the future. Note, that does not fix a real problem, since currently no virtual regions of size less than (PAGE_SIZE << 3) exist.

2023-06-20x86/smp: Put CPUs into INIT on shutdown if possibleThomas Gleixner
Parking CPUs in a HLT loop is not completely safe vs. kexec() as HLT can resume execution due to NMI, SMI and MCE, which has the same issue as the MWAIT loop. Kicking the secondary CPUs into INIT makes this safe against NMI and SMI. A broadcast MCE will take the machine down, but a broadcast MCE which makes HLT resume and execute overwritten text, pagetables or data will end up in a disaster too. So chose the lesser of two evils and kick the secondary CPUs into INIT unless the system has installed special wakeup mechanisms which are not using INIT.

2023-06-20x86/smp: Cure kexec() vs. mwait_play_dead() breakageThomas Gleixner
TLDR: It's a mess. When kexec() is executed on a system with offline CPUs, which are parked in mwait_play_dead() it can end up in a triple fault during the bootup of the kexec kernel or cause hard to diagnose data corruption. The reason is that kexec() eventually overwrites the previous kernel's text, page tables, data and stack. If it writes to the cache line which is monitored by a previously offlined CPU, MWAIT resumes execution and ends up executing the wrong text, dereferencing overwritten page tables or corrupting the kexec kernels data. Cure this by bringing the offlined CPUs out of MWAIT into HLT. Write to the monitored cache line of each offline CPU, which makes MWAIT resume execution. The written control word tells the offlined CPUs to issue HLT, which does not have the MWAIT problem. That does not help, if a stray NMI, MCE or SMI hits the offlined CPUs as those make it come out of HLT. A follow up change will put them into INIT, which protects at least against NMI and SMI.

2023-06-20x86/smp: Use dedicated cache-line for mwait_play_dead()Thomas Gleixner
Monitoring idletask::thread_info::flags in mwait_play_dead() has been an obvious choice as all what is needed is a cache line which is not written by other CPUs. But there is a use case where a "dead" CPU needs to be brought out of MWAIT: kexec(). This is required as kexec() can overwrite text, pagetables, stacks and the monitored cacheline of the original kernel. The latter causes MWAIT to resume execution which obviously causes havoc on the kexec kernel which results usually in triple faults. Use a dedicated per CPU storage to prepare for that.

stop_this_cpu() tests CPUID leaf 0x8000001f::EAX unconditionally. Intel CPUs return the content of the highest supported leaf when a non-existing leaf is read, while AMD CPUs return all zeros for unsupported leafs. So the result of the test on Intel CPUs is lottery. While harmless it's incorrect and causes the conditional wbinvd() to be issued where not required.

2023-06-20x86/smp: Make stop_other_cpus() more robustThomas Gleixner
Tony reported intermittent lockups on poweroff. His analysis identified the wbinvd() in stop_this_cpu() as the culprit. This was added to ensure that on SME enabled machines a kexec() does not leave any stale data in the caches when switching from encrypted to non-encrypted mode or vice versa. That wbinvd() is conditional on the SME feature bit which is read directly from CPUID. But that readout does not check whether the CPUID leaf is available or not. If it's not available the CPU will return the value of the highest supported leaf instead. Depending on the content the "SME" bit might be set or not. That's incorrect but harmless. Making the CPUID readout conditional makes the observed hangs go away, but it does not fix the underlying problem: CPU0 CPU1 stop_other_cpus() send_IPIs(REBOOT); stop_this_cpu() while (num_online_cpus() > 1); set_online(false); proceed... -> hang wbinvd() WBINVD is an expensive operation and if multiple CPUs issue it at the same time the resulting delays are even larger. But CPU0 already observed num_online_cpus() going down to 1 and proceeds which causes the system to hang. This issue exists independent of WBINVD, but the delays caused by WBINVD make it more prominent. Make this more robust by adding a cpumask which is initialized to the online CPU mask before sending the IPIs and CPUs clear their bit in stop_this_cpu() after the WBINVD completed. Check for that cpumask to become empty in stop_other_cpus() instead of watching num_online_cpus(). The cpumask cannot plug all holes either, but it's better than a raw counter and allows to restrict the NMI fallback IPI to be sent only the CPUs which have not reported within the timeout window.

2023-06-20MIPS: PCI: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. While destroying alignment of the assignments in bridge_driver, do it consistently and use a single space before =.

2023-06-19riscv: mm: Pre-allocate PGD entries for vmalloc/modules areaBjörn Töpel
The RISC-V port requires that kernel PGD entries are to be synchronized between MMs. This is done via the vmalloc_fault() function, that simply copies the PGD entries from init_mm to the faulting one. Historically, faulting in PGD entries have been a source for both bugs [1], and poor performance. One way to get rid of vmalloc faults is by pre-allocating the PGD entries. Pre-allocating the entries potientially wastes 64 * 4K (65 on SV39). The pre-allocation function is pulled from Jörg Rödel's x86 work, with the addition of 3-level page tables (PMD allocations). The pmd_alloc() function needs the ptlock cache to be initialized (when split page locks is enabled), so the pre-allocation is done in a RISC-V specific pgtable_cache_init() implementation. Pre-allocate the kernel PGD entries for the vmalloc/modules area, but only for 64b platforms.

2023-06-19watchdog/hardlockup: make HAVE_NMI_WATCHDOG sparc64-specificPetr Mladek
There are several hardlockup detector implementations and several Kconfig values which allow selection and build of the preferred one. CONFIG_HARDLOCKUP_DETECTOR was introduced by the commit 23637d477c1f53acb ("lockup_detector: Introduce CONFIG_HARDLOCKUP_DETECTOR") in v2.6.36. It was a preparation step for introducing the new generic perf hardlockup detector. The existing arch-specific variants did not support the to-be-created generic build configurations, sysctl interface, etc. This distinction was made explicit by the commit 4a7863cc2eb5f98 ("x86, nmi_watchdog: Remove ARCH_HAS_NMI_WATCHDOG and rely on CONFIG_HARDLOCKUP_DETECTOR") in v2.6.38. CONFIG_HAVE_NMI_WATCHDOG was introduced by the commit d314d74c695f967e105 ("nmi watchdog: do not use cpp symbol in Kconfig") in v3.4-rc1. It replaced the above mentioned ARCH_HAS_NMI_WATCHDOG. At that time, it was still used by three architectures, namely blackfin, mn10300, and sparc. The support for blackfin and mn10300 architectures has been completely dropped some time ago. And sparc is the only architecture with the historic NMI watchdog at the moment. And the old sparc implementation is really special. It is always built on sparc64. It used to be always enabled until the commit 7a5c8b57cec93196b ("sparc: implement watchdog_nmi_enable and watchdog_nmi_disable") added in v4.10-rc1. There are only few locations where the sparc64 NMI watchdog interacts with the generic hardlockup detectors code: + implements arch_touch_nmi_watchdog() which is called from the generic touch_nmi_watchdog() + implements watchdog_hardlockup_enable()/disable() to support /proc/sys/kernel/nmi_watchdog + is always preferred over other generic watchdogs, see CONFIG_HARDLOCKUP_DETECTOR + includes asm/nmi.h into linux/nmi.h because some sparc-specific functions are needed in sparc-specific code which includes only linux/nmi.h. The situation became more complicated after the commit 05a4a95279311c3 ("kernel/watchdog: split up config options") and commit 2104180a53698df5 ("powerpc/64s: implement arch-specific hardlockup watchdog") in v4.13-rc1. They introduced HAVE_HARDLOCKUP_DETECTOR_ARCH. It was used for powerpc specific hardlockup detector. It was compatible with the perf one regarding the general boot, sysctl, and programming interfaces. HAVE_HARDLOCKUP_DETECTOR_ARCH was defined as a superset of HAVE_NMI_WATCHDOG. It made some sense because all arch-specific detectors had some common requirements, namely: + implemented arch_touch_nmi_watchdog() + included asm/nmi.h into linux/nmi.h + defined the default value for /proc/sys/kernel/nmi_watchdog But it actually has made things pretty complicated when the generic buddy hardlockup detector was added. Before the generic perf detector was newer supported together with an arch-specific one. But the buddy detector could work on any SMP system. It means that an architecture could support both the arch-specific and buddy detector. As a result, there are few tricky dependencies. For example, CONFIG_HARDLOCKUP_DETECTOR depends on: ((HAVE_HARDLOCKUP_DETECTOR_PERF || HAVE_HARDLOCKUP_DETECTOR_BUDDY) && !HAVE_NMI_WATCHDOG) || HAVE_HARDLOCKUP_DETECTOR_ARCH The problem is that the very special sparc implementation is defined as: HAVE_NMI_WATCHDOG && !HAVE_HARDLOCKUP_DETECTOR_ARCH Another problem is that the meaning of HAVE_NMI_WATCHDOG is far from clear without reading understanding the history. Make the logic less tricky and more self-explanatory by making HAVE_NMI_WATCHDOG specific for the sparc64 implementation. And rename it to HAVE_HARDLOCKUP_DETECTOR_SPARC64. Note that HARDLOCKUP_DETECTOR_PREFER_BUDDY, HARDLOCKUP_DETECTOR_PERF, and HARDLOCKUP_DETECTOR_BUDDY may conflict only with HAVE_HARDLOCKUP_DETECTOR_ARCH. They depend on HARDLOCKUP_DETECTOR and it is not longer enabled when HAVE_NMI_WATCHDOG is set.

2023-06-19watchdog/hardlockup: declare arch_touch_nmi_watchdog() only in linux/nmi.hPetr Mladek
arch_touch_nmi_watchdog() needs a different implementation for various hardlockup detector implementations. And it does nothing when any hardlockup detector is not built at all. arch_touch_nmi_watchdog() is declared via linux/nmi.h. And it must be defined as an empty function when there is no hardlockup detector. It is done directly in this header file for the perf and buddy detectors. And it is done in the included asm/linux.h for arch specific detectors. The reason probably is that the arch specific variants build the code using another conditions. For example, powerpc64/sparc64 builds the code when CONFIG_PPC_WATCHDOG is enabled. Another reason might be that these architectures define more functions in asm/nmi.h anyway. However the generic code actually knows when the function will be implemented. It happens when some full featured or the sparc64-specific hardlockup detector is built. In particular, CONFIG_HARDLOCKUP_DETECTOR can be enabled only when a generic or arch-specific full featured hardlockup detector is available. The only exception is sparc64 which can be built even when the global HARDLOCKUP_DETECTOR switch is disabled. The information about sparc64 is a bit complicated. The hardlockup detector is built there when CONFIG_HAVE_NMI_WATCHDOG is set and CONFIG_HAVE_HARDLOCKUP_DETECTOR_ARCH is not set. People might wonder whether this change really makes things easier. The motivation is: + The current logic in linux/nmi.h is far from obvious. For example, arch_touch_nmi_watchdog() is defined as {} when neither CONFIG_HARDLOCKUP_DETECTOR_COUNTS_HRTIMER nor CONFIG_HAVE_NMI_WATCHDOG is defined. + The change synchronizes the checks in lib/Kconfig.debug and in the generic code. + It is a step that will help cleaning HAVE_NMI_WATCHDOG related checks. The change should not change the existing behavior.

2023-06-19watchdog/hardlockup: make the config checks more straightforwardPetr Mladek
There are four possible variants of hardlockup detectors: + buddy: available when SMP is set. + perf: available when HAVE_HARDLOCKUP_DETECTOR_PERF is set. + arch-specific: available when HAVE_HARDLOCKUP_DETECTOR_ARCH is set. + sparc64 special variant: available when HAVE_NMI_WATCHDOG is set and HAVE_HARDLOCKUP_DETECTOR_ARCH is not set. The check for the sparc64 variant is more complicated because HAVE_NMI_WATCHDOG is used to #ifdef code used by both arch-specific and sparc64 specific variant. Therefore it is automatically selected with HAVE_HARDLOCKUP_DETECTOR_ARCH. This complexity is partly hidden in HAVE_HARDLOCKUP_DETECTOR_NON_ARCH. It reduces the size of some checks but it makes them harder to follow. Finally, the other temporary variable HARDLOCKUP_DETECTOR_NON_ARCH is used to re-compute HARDLOCKUP_DETECTOR_PERF/BUDDY when the global HARDLOCKUP_DETECTOR switch is enabled/disabled. Make the logic more straightforward by the following changes: + Better explain the role of HAVE_HARDLOCKUP_DETECTOR_ARCH and HAVE_NMI_WATCHDOG in comments. + Add HAVE_HARDLOCKUP_DETECTOR_BUDDY so that there is separate HAVE_* for all four hardlockup detector variants. Use it in the other conditions instead of SMP. It makes it clear that it is about the buddy detector. + Open code HAVE_HARDLOCKUP_DETECTOR_NON_ARCH in HARDLOCKUP_DETECTOR and HARDLOCKUP_DETECTOR_PREFER_BUDDY. It helps to understand the conditions between the four hardlockup detector variants. + Define the exact conditions when HARDLOCKUP_DETECTOR_PERF/BUDDY can be enabled. It explains the dependency on the other hardlockup detector variants. Also it allows to remove HARDLOCKUP_DETECTOR_NON_ARCH by using "imply". It triggers re-evaluating HARDLOCKUP_DETECTOR_PERF/BUDDY when the global HARDLOCKUP_DETECTOR switch is changed. + Add dependency on HARDLOCKUP_DETECTOR so that the affected variables disappear when the hardlockup detectors are disabled. Another nice side effect is that HARDLOCKUP_DETECTOR_PREFER_BUDDY value is not preserved when the global switch is disabled. The user has to make the decision again when it gets re-enabled.

2023-06-19watchdog/hardlockup: HAVE_NMI_WATCHDOG must implement ↵Douglas Anderson
watchdog_hardlockup_probe() Right now there is one arch (sparc64) that selects HAVE_NMI_WATCHDOG without selecting HAVE_HARDLOCKUP_DETECTOR_ARCH. Because of that one architecture, we have some special case code in the watchdog core to handle the fact that watchdog_hardlockup_probe() isn't implemented. Let's implement watchdog_hardlockup_probe() for sparc64 and get rid of the special case. As a side effect of doing this, code inspection tells us that we could fix a minor bug where the system won't properly realize that NMI watchdogs are disabled. Specifically, on powerpc if CONFIG_PPC_WATCHDOG is turned off the arch might still select CONFIG_HAVE_HARDLOCKUP_DETECTOR_ARCH which selects CONFIG_HAVE_NMI_WATCHDOG. Since CONFIG_PPC_WATCHDOG was off then nothing will override the "weak" watchdog_hardlockup_probe() and we'll fallback to looking at CONFIG_HAVE_NMI_WATCHDOG.
