Pull clk updates from Stephen Boyd: "We have one small patch to the clk core this time around. It fixes a corner case with the CLK_OPS_PARENT_ENABLE flag combined with clk_core_is_enabled() where it hangs the system. We'll simply assume the clk is disabled if the parent is disabled and the flag is set. Trying to turn on the parent to check the enable state of the clk runs into system hangs at boot. We let this bake in -next for a couple weeks to make sure there aren't any more issues because the last attempt to fix this ran into hangs and had to be reverted. Note: There were some more patches to the core framework around sync_state and disabling unused clks, but I asked for that to be reverted from the qcom PR because it isn't ready and we're still discussing the best solution on the list. Outside of the core clk framework, we have the usual collection of clk driver updates and support for new SoCs (which seems to never stop). The dirstat is dominated by Qualcomm because they added support for quite a few SoCs this time around and also migrated quite a few of their drivers to clk_parent_data. The other big diff is in the Mediatek clk drivers that saw a significant rework this cycle to similarly modernize the code, and we'll see that work continue in the next cycle as well. Nothing really jumps out as scary here, except that the significant churn in parent data descriptions can have typos that go unnoticed. More details below. Core: - Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled() New Drivers: - Add a new clk-gpr-mux clock type and use it on i.MX6Q to add ENET ref clocks - Support for Mediatek MT7891 SoC clks - Support for many Qualcomm clk controllers: - QDU1000/QRU1000 global clock controller - SA8775P global clock controller - SM8550 TCSR and display clock controller - SM6350 clock controller - MSM8996 CBF and APCS clock controllers Updates: - Various cleanups and improvements to Mediatek clk drivers to reduce code size and modernize the drivers - Support for Versa 5P49V60 clks - Disable R-Car H3 ES1.*, as it was only available to an internal development group and needed a lot of quirks and workarounds - Add PWM, Compare-Match Timer (TIM), USB, SDHI, and eMMC clocks and resets on Renesas RZ/V2M - Add display clocks on Renesas R-Car V4H - Add Camera Receiving Unit (CRU) clocks and resets on Renesas RZ/G2L - Free the imx_uart_clocks even if imx_register_uart_clocks returns early - Get the stdout clocks count from device tree on i.MX - Drop the clock count argument from imx_register_uart_clocks() - Keep the uart clocks on i.MX93 for when earlycon is used - Fix SPDX comment in i.MX6SLL clocks bindings header - Drop some unnecessary spaces from i.MX8ULP clocks bindings header - Add imx_obtain_fixed_of_clock() for allowing to add a clock that is not configured via devicetree - Fix the ENET1 gate configuration for i.MX6UL according to the reference manual - Add ENET refclock mux support for i.MX6UL - Add support for USB host/device configuration on Renesas RZ/N1 - Add PLL2 programming support, and CAN-FD clocks on Renesas R-Car V4H - Add D1 CAN bus gates and resets for Allwinner - Mark D1 CPUX clock as critical on Allwinner - Reuse D1 driver for Allwinner R528/T113 - Cleanup sunxi-ng Kconfig - Fix sunxi-ng kernel-doc issues - Model Allwinner H3/H5 DRAM clock as fixed clock - Use .determine_rate() instead of .round_rate() for the dualdiv, mpll, sclk-div and cpu-dyn-div amlogic clock drivers - DDR clocks were marked as critical in the proper clock driver for each AT91 SoC such that drivers/memory/atmel-sdramc.c to be deleted in the next releases as it only does clock enablement - Patch to avoid compiling dt-compat.o for all AT91 SoCs as only some of them may use it - Support synchronous power_off requests in the qcom GDSC driver for proper GPU power collapse - Drop test clocks from various Qualcomm clk drivers - Update parent references to use clk_parent_data/clk_hw in various Qualcomm clk drivers - Fixes for the Qualcomm MSM8996 CPU clock controller - Transition Qualcomm MSM8974 GCC off the externally defined sleep_clk - Add GDSCs in the global clock controller for Qualcomm QCS404 - The SDCC core clocks on Qualcomm SM6115 are moved to floor_ops - Programming of clk_dis_wait for GPU CX GDSC on Qualcomm SC7180 and SDM845 are moved to use the recently introduced properties in the GDSC struct - Qualcomm's RPMh clock driver gains SM8550 and SA8775P clocks, and the IPA clock is added on a variety of platforms - De-duplicate identical clks in Qualcomm SMD RPM clk driver - Add a few missing clocks across msm8998, msm8992, msm8916, qcs404 to Qualcomm SDM RPM clk driver - Various Qualcomm clk drivers use devm_pm_runtime_enable() to simplify" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (228 commits) clk: qcom: apcs-msm8986: Include bitfield.h for FIELD_PREP clk: qcom: Revert sync_state based clk_disable_unused clk: imx: pll14xx: fix recalc_rate for negative kdiv clk: rs9: Drop unused pin_xin field MAINTAINERS: clk: imx: Add Peng Fan as reviewer clk: sprd: Add dependency for SPRD_UMS512_CLK clk: ralink: fix 'mt7621_gate_is_enabled()' function clk: mediatek: clk-mtk: Remove unneeded semicolon dt-bindings: clock: remove stih416 bindings dt-bindings: clock: add loongson-2 clock dt-bindings: clock: add loongson-2 clock include file clk: imx: fix compile testing imxrt1050 clk: Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled() clk: imx: set imx_clk_gpr_mux_ops storage-class-specifier to static clk: renesas: rcar-gen3: Disable R-Car H3 ES1.* dt-bindings: clock: Merge qcom,gpucc-sm8350 into qcom,gpucc.yaml clk: qcom: gpucc-sdm845: fix clk_dis_wait being programmed for CX GDSC clk: qcom: gpucc-sc7180: fix clk_dis_wait being programmed for CX GDSC dt-bindings: clock: qcom,sa8775p-gcc: add the power-domains property clk: qcom: cpu-8996: add missing cputype include ...

Pull kvm updates from Paolo Bonzini: "ARM: - Provide a virtual cache topology to the guest to avoid inconsistencies with migration on heterogenous systems. Non secure software has no practical need to traverse the caches by set/way in the first place - Add support for taking stage-2 access faults in parallel. This was an accidental omission in the original parallel faults implementation, but should provide a marginal improvement to machines w/o FEAT_HAFDBS (such as hardware from the fruit company) - A preamble to adding support for nested virtualization to KVM, including vEL2 register state, rudimentary nested exception handling and masking unsupported features for nested guests - Fixes to the PSCI relay that avoid an unexpected host SVE trap when resuming a CPU when running pKVM - VGIC maintenance interrupt support for the AIC - Improvements to the arch timer emulation, primarily aimed at reducing the trap overhead of running nested - Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the interest of CI systems - Avoid VM-wide stop-the-world operations when a vCPU accesses its own redistributor - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions in the host - Aesthetic and comment/kerneldoc fixes - Drop the vestiges of the old Columbia mailing list and add [Oliver] as co-maintainer RISC-V: - Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE - Correctly place the guest in S-mode after redirecting a trap to the guest - Redirect illegal instruction traps to guest - SBI PMU support for guest s390: - Sort out confusion between virtual and physical addresses, which currently are the same on s390 - A new ioctl that performs cmpxchg on guest memory - A few fixes x86: - Change tdp_mmu to a read-only parameter - Separate TDP and shadow MMU page fault paths - Enable Hyper-V invariant TSC control - Fix a variety of APICv and AVIC bugs, some of them real-world, some of them affecting architecurally legal but unlikely to happen in practice - Mark APIC timer as expired if its in one-shot mode and the count underflows while the vCPU task was being migrated - Advertise support for Intel's new fast REP string features - Fix a double-shootdown issue in the emergency reboot code - Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give SVM similar treatment to VMX - Update Xen's TSC info CPUID sub-leaves as appropriate - Add support for Hyper-V's extended hypercalls, where "support" at this point is just forwarding the hypercalls to userspace - Clean up the kvm->lock vs. kvm->srcu sequences when updating the PMU and MSR filters - One-off fixes and cleanups - Fix and cleanup the range-based TLB flushing code, used when KVM is running on Hyper-V - Add support for filtering PMU events using a mask. If userspace wants to restrict heavily what events the guest can use, it can now do so without needing an absurd number of filter entries - Clean up KVM's handling of "PMU MSRs to save", especially when vPMU support is disabled - Add PEBS support for Intel Sapphire Rapids - Fix a mostly benign overflow bug in SEV's send|receive_update_data() - Move several SVM-specific flags into vcpu_svm x86 Intel: - Handle NMI VM-Exits before leaving the noinstr region - A few trivial cleanups in the VM-Enter flows - Stop enabling VMFUNC for L1 purely to document that KVM doesn't support EPTP switching (or any other VM function) for L1 - Fix a crash when using eVMCS's enlighted MSR bitmaps Generic: - Clean up the hardware enable and initialization flow, which was scattered around multiple arch-specific hooks. Instead, just let the arch code call into generic code. Both x86 and ARM should benefit from not having to fight common KVM code's notion of how to do initialization - Account allocations in generic kvm_arch_alloc_vm() - Fix a memory leak if coalesced MMIO unregistration fails selftests: - On x86, cache the CPU vendor (AMD vs. Intel) and use the info to emit the correct hypercall instruction instead of relying on KVM to patch in VMMCALL - Use TAP interface for kvm_binary_stats_test and tsc_msrs_test" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (325 commits) KVM: SVM: hyper-v: placate modpost section mismatch error KVM: x86/mmu: Make tdp_mmu_allowed static KVM: arm64: nv: Use reg_to_encoding() to get sysreg ID KVM: arm64: nv: Only toggle cache for virtual EL2 when SCTLR_EL2 changes KVM: arm64: nv: Filter out unsupported features from ID regs KVM: arm64: nv: Emulate EL12 register accesses from the virtual EL2 KVM: arm64: nv: Allow a sysreg to be hidden from userspace only KVM: arm64: nv: Emulate PSTATE.M for a guest hypervisor KVM: arm64: nv: Add accessors for SPSR_EL1, ELR_EL1 and VBAR_EL1 from virtual EL2 KVM: arm64: nv: Handle SMCs taken from virtual EL2 KVM: arm64: nv: Handle trapped ERET from virtual EL2 KVM: arm64: nv: Inject HVC exceptions to the virtual EL2 KVM: arm64: nv: Support virtual EL2 exceptions KVM: arm64: nv: Handle HCR_EL2.NV system register traps KVM: arm64: nv: Add nested virt VCPU primitives for vEL2 VCPU state KVM: arm64: nv: Add EL2 system registers to vcpu context KVM: arm64: nv: Allow userspace to set PSR_MODE_EL2x KVM: arm64: nv: Reset VCPU to EL2 registers if VCPU nested virt is set KVM: arm64: nv: Introduce nested virtualization VCPU feature KVM: arm64: Use the S2 MMU context to iterate over S2 table ...

Pull Compute Express Link (CXL) updates from Dan Williams: "To date Linux has been dependent on platform-firmware to map CXL RAM regions and handle events / errors from devices. With this update we can now parse / update the CXL memory layout, and report events / errors from devices. This is a precursor for the CXL subsystem to handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that for DDR-attached-DRAM is handled by the EDAC driver where it maps system physical address events to a field-replaceable-unit (FRU / endpoint device). In general, CXL has the potential to standardize what has historically been a pile of memory-controller-specific error handling logic. Another change of note is the default policy for handling RAM-backed device-dax instances. Previously the default access mode was "device", mmap(2) a device special file to access memory. The new default is "kmem" where the address range is assigned to the core-mm via add_memory_driver_managed(). This saves typical users from wondering why their platform memory is not visible via free(1) and stuck behind a device-file. At the same time it allows expert users to deploy policy to, for example, get dedicated access to high performance memory, or hide low performance memory from general purpose kernel allocations. This affects not only CXL, but also systems with high-bandwidth-memory that platform-firmware tags with the EFI_MEMORY_SP (special purpose) designation. Summary: - CXL RAM region enumeration: instantiate 'struct cxl_region' objects for platform firmware created memory regions - CXL RAM region provisioning: complement the existing PMEM region creation support with RAM region support - "Soft Reservation" policy change: Online (memory hot-add) soft-reserved memory (EFI_MEMORY_SP) by default, but still allow for setting aside such memory for dedicated access via device-dax. - CXL Events and Interrupts: Takeover CXL event handling from platform-firmware (ACPI calls this CXL Memory Error Reporting) and export CXL Events via Linux Trace Events. - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL subsystem interrogate the result of CXL _OSC negotiation. - Emulate CXL DVSEC Range Registers as "decoders": Allow for first-generation devices that pre-date the definition of the CXL HDM Decoder Capability to translate the CXL DVSEC Range Registers into 'struct cxl_decoder' objects. - Set timestamp: Per spec, set the device timestamp in case of hotplug, or if platform-firwmare failed to set it. - General fixups: linux-next build issues, non-urgent fixes for pre-production hardware, unit test fixes, spelling and debug message improvements" * tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (66 commits) dax/kmem: Fix leak of memory-hotplug resources cxl/mem: Add kdoc param for event log driver state cxl/trace: Add serial number to trace points cxl/trace: Add host output to trace points cxl/trace: Standardize device information output cxl/pci: Remove locked check for dvsec_range_allowed() cxl/hdm: Add emulation when HDM decoders are not committed cxl/hdm: Create emulated cxl_hdm for devices that do not have HDM decoders cxl/hdm: Emulate HDM decoder from DVSEC range registers cxl/pci: Refactor cxl_hdm_decode_init() cxl/port: Export cxl_dvsec_rr_decode() to cxl_port cxl/pci: Break out range register decoding from cxl_hdm_decode_init() cxl: add RAS status unmasking for CXL cxl: remove unnecessary calling of pci_enable_pcie_error_reporting() dax/hmem: build hmem device support as module if possible dax: cxl: add CXL_REGION dependency cxl: avoid returning uninitialized error code cxl/pmem: Fix nvdimm registration races cxl/mem: Fix UAPI command comment cxl/uapi: Tag commands from cxl_query_cmd() ...

On each context switch we save the FPU registers on stack of old process and restore FPU registers from the stack of new one. That allows us to avoid doing that each time we enter/leave the kernel mode; however, that can get suboptimal in some cases. For one thing, we don't need to bother saving anything for kernel threads. For another, if between entering and leaving the kernel a thread gives CPU up more than once, it will do useless work, saving the same values every time, only to discard the saved copy as soon as it returns from switch_to(). Alternative solution: * move the array we save into from switch_stack to thread_info * have a (thread-synchronous) flag set when we save them * have another flag set when they should be restored on return to userland. * do *NOT* save/restore them in do_switch_stack()/undo_switch_stack(). * restore on the exit to user mode if the restore flag had been set. Clear both flags. * on context switch, entry to fork/clone/vfork, before entry into do_signal() and on entry into straced syscall save the registers and set the 'saved' flag unless it had been already set. * on context switch set the 'restore' flag as well. * have copy_thread() set both flags for child, so the registers would be restored once the child returns to userland. * use the saved data in setup_sigcontext(); have restore_sigcontext() set both flags and copy from sigframe to save area. * teach ptrace to look for FPU registers in thread_info instead of switch_stack. * teach isolated accesses to FPU registers (rdfpcr, wrfpcr, etc.) to check the 'saved' flag (under preempt_disable()) and work with the save area if it's been set; if 'saved' flag is found upon write access, set 'restore' flag as well.

Type 3 instruction fault (FPU insn with FPU disabled) is handled by quietly enabling FPU and returning. Which is fine, except that we need to do that both for fault in userland and in the kernel; the latter *can* legitimately happen - all it takes is this: .global _start _start: call_pal 0xae lda $0, 0 ldq $0, 0($0) - call_pal CLRFEN to clear "FPU enabled" flag and arrange for a signal delivery (SIGSEGV in this case). Fixed by moving the handling of type 3 into the common part of do_entIF(), before we check for kernel vs. user mode. Incidentally, check for kernel mode is unidiomatic; the normal way to do that is !user_mode(regs). The difference is that the open-coded variant treats any of bits 63..3 of regs->ps being set as "it's user mode" while the normal approach is to check just the bit 3. PS is a 4-bit register and regs->ps always will have bits 63..4 clear, so the open-code variant here is actually equivalent to !user_mode(regs). Harder to follow, though... Reproducer above will crash any box where CLRFEN is not ignored by PAL (== any actual hardware, AFAICS; PAL used in qemu doesn't bother implementing that crap).

Pull iommu updates from Joerg Roedel: - Consolidate iommu_map/unmap functions. There have been blocking and atomic variants so far, but that was problematic as this approach does not scale with required new variants which just differ in the GFP flags used. So Jason consolidated this back into single functions that take a GFP parameter. - Retire the detach_dev() call-back in iommu_ops - Arm SMMU updates from Will: - Device-tree binding updates: - Cater for three power domains on SM6375 - Document existing compatible strings for Qualcomm SoCs - Tighten up clocks description for platform-specific compatible strings - Enable Qualcomm workarounds for some additional platforms that need them - Intel VT-d updates from Lu Baolu: - Add Intel IOMMU performance monitoring support - Set No Execute Enable bit in PASID table entry - Two performance optimizations - Fix PASID directory pointer coherency - Fix missed rollbacks in error path - Cleanups - Apple t8110 DART support - Exynos IOMMU: - Implement better fault handling - Error handling fixes - Renesas IPMMU: - Add device tree bindings for r8a779g0 - AMD IOMMU: - Various fixes for handling on SNP-enabled systems and handling of faults with unknown request-ids - Cleanups and other small fixes - Various other smaller fixes and cleanups * tag 'iommu-updates-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (71 commits) iommu/amd: Skip attach device domain is same as new domain iommu: Attach device group to old domain in error path iommu/vt-d: Allow to use flush-queue when first level is default iommu/vt-d: Fix PASID directory pointer coherency iommu/vt-d: Avoid superfluous IOTLB tracking in lazy mode iommu/vt-d: Fix error handling in sva enable/disable paths iommu/amd: Improve page fault error reporting iommu/amd: Do not identity map v2 capable device when snp is enabled iommu: Fix error unwind in iommu_group_alloc() iommu/of: mark an unused function as __maybe_unused iommu: dart: DART_T8110_ERROR range should be 0 to 5 iommu/vt-d: Enable IOMMU perfmon support iommu/vt-d: Add IOMMU perfmon overflow handler support iommu/vt-d: Support cpumask for IOMMU perfmon iommu/vt-d: Add IOMMU perfmon support iommu/vt-d: Support Enhanced Command Interface iommu/vt-d: Retrieve IOMMU perfmon capability information iommu/vt-d: Support size of the register set in DRHD iommu/vt-d: Set No Execute Enable bit in PASID table entry iommu/vt-d: Remove sva from intel_svm_dev ...

Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...
