More Qualcomm driver updates for v5.16 This introduces the Qualcomm "sleep stats" driver, which aids the efforts of bringing various Qualcomm platforms into low power mode. The SMP2P driver gains support for negotiating the "SSR" feature, which is used to better synchronize some corner cases that might appear as the remoteproc is recovering from a crash. The socinfo driver learns about a few new PMICs. SMEM is updated so that it's possible to put the compatible property directly in the reserved-memory node, to avoid having to have a separate node just pointing to the memory-region. Lastly it fixes some bugs in smp2p, apr, rpmhpd drivers, notably avoiding the issue where powering on a power-domain using rpmhpd while keeping the performance_state at 0 is a nop * tag 'qcom-drivers-for-5.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: firmware: qcom: scm: Don't break compile test on non-ARM platforms soc: qcom: smp2p: Add of_node_put() before goto soc: qcom: apr: Add of_node_put() before return soc: qcom: qcom_stats: Fix client votes offset soc: qcom: rpmhpd: fix sm8350_mxc's peer domain dt-bindings: arm: cpus: Document qcom,msm8916-smp enable-method ARM: qcom: Add qcom,msm8916-smp enable-method identical to MSM8226 firmware: qcom: scm: Add support for MC boot address API soc: qcom: spm: Add 8916 SPM register data dt-bindings: soc: qcom: spm: Document qcom,msm8916-saw2-v3.0-cpu soc: qcom: socinfo: Add PM8150C and SMB2351 models firmware: qcom_scm: Fix error retval in __qcom_scm_is_call_available() soc: qcom: smp2p: add feature negotiation and ssr ack feature support soc: qcom: Add Sleep stats driver dt-bindings: Introduce QCOM Sleep stats bindings soc: qcom: socinfo: add two missing PMIC IDs soc: qcom: rpmhpd: Make power_on actually enable the domain soc: qcom: smem: Support reserved-memory description dt-bindings: soc: smem: Make indirection optional dt-bindings: sram: Document qcom,rpm-msg-ram Link: https://lore.kernel.org/r/20211026140706.1205989-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Samsung SoC drivers changes for v5.16 1. Convert Exynos ChipID and ASV driver to a module and make it a default, instead of selected. The driver is not essential, so it could be disabled, if needed. 2. Add support for Exynos850 and Exynos Auto v9 to Exynos ChipID and ASV driver. 3. Get rid of HAVE_S3C_RTC because it was adding just another layer instead of direct dependencies. 4.

2021-10-26s390/pci: add s390_iommu_aperture kernel parameterNiklas Schnelle1-0/+12
Some applications map the same memory area for DMA multiple times while also mapping significant amounts of memory. With our current DMA code these applications will run out of DMA addresses after mapping half of the available memory because the number of DMA mappings is constrained by the number of concurrently active DMA addresses we support which in turn is limited by the minimum of hardware constraints and high_memory. Limiting the number of active DMA addresses to high_memory is only a heuristic to save memory used by the iommu_bitmap and DMA page tables however. This was added under the assumption that it rarely makes sense to DMA map more than system memory. To accommodate special applications which insist on double mapping, which works on other platforms, allow specifying a factor of how many times installed memory is available as DMA address space. Use 0 as a special value to apply no constraints beyond what hardware dictates at the expense of significantly more memory use.

2021-10-26irq: remove handle_domain_{irq,nmi}()Mark Rutland1-3/+0
Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

2021-10-26x86/signal: Implement sigaltstack size validationThomas Gleixner1-0/+9
For historical reasons MINSIGSTKSZ is a constant which became already too small with AVX512 support. Add a mechanism to enforce strict checking of the sigaltstack size against the real size of the FPU frame. The strict check can be enabled via a config option and can also be controlled via the kernel command line option 'strict_sas_size' independent of the config switch. Enabling it might break existing applications which allocate a too small sigaltstack but 'work' because they never get a signal delivered. Though it can be handy to filter out binaries which are not yet aware of AT_MINSIGSTKSZ. Also the upcoming support for dynamically enabled FPU features requires a strict sanity check to ensure that: - Enabling of a dynamic feature, which changes the sigframe size fits into an enabled sigaltstack - Installing a too small sigaltstack after a dynamic feature has been added is not possible. Implement the base check which is controlled by config and command line options. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Chang S.

The current doc of workqueue API suggests that work items are non-reentrant: any work item is guaranteed to be executed by at most one worker system-wide at any given time. However this is not true, the following case can cause a work item W executed by two workers at the same time: queue_work_on(0, WQ1, W); // after a worker picks up W and clear the pending bit queue_work_on(1, WQ2, W); // workers on CPU0 and CPU1 will execute W in the same time. , which means the non-reentrance of a work item is conditional, and Lai Jiangshan provided a nice summary[1] of the conditions, therefore use it to describe a work item instance and improve the doc.

2021-10-24kbuild: use more subdir- for visiting subdirectories while cleaningMasahiro Yamada1-15/+2
Documentation/kbuild/makefiles.rst suggests to use "archclean" for cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement. Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures. This can take advantage of the parallel option (-j) for "make clean". I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep" target no longer exists.

2021-10-23dt-bindings: arm: cpus: Document qcom,msm8916-smp enable-methodStephan Gerhold1-1/+4
Since MSM8916 is an ARM v8 64-bit SoC the CPU cores are normally booted using "psci" or "spin-table". Unfortunately, some devices come with signed 32-bit-only firmware without ARM64 and PSCI support. This setup is easy to support since it's very similar to older 32-bit only Qualcomm SoCs (e.g. MSM8226) and only requires adding a few new definitions to already existing drivers. Document the qcom,msm8916-smp enable-method. It is actually just an alias of qcom,msm8226-smp since it should be implemented identically. The enable-method is only valid on ARM32 and must not be used on ARM64.
