crashkernel reservation failed on a Thinkpad t440s laptop recently. Actually the memblock reservation succeeded, but later insert_resource() failed. Test steps: kexec load -> /* make sure add crashkernel param eg. crashkernel=160M */ kexec reboot -> dmesg|grep "crashkernel reserved"; crashkernel memory range like below reserved successfully: 0x00000000d0000000 - 0x00000000da000000 But no such "Crash kernel" region in /proc/iomem The background story: Currently the E820 code reserves setup_data regions for both the current kernel and the kexec kernel, and it inserts them into the resources list. Before the kexec kernel reboots nobody passes the old setup_data, and kexec only passes fresh SETUP_EFI/SETUP_IMA/SETUP_RNG_SEED if needed. Thus the old setup data memory is not used at all. Due to old kernel updates the kexec e820 table as well so kexec kernel sees them as E820_TYPE_RESERVED_KERN regions, and later the old setup_data regions are inserted into resources list in the kexec kernel by e820__reserve_resources(). Note, due to no setup_data is passed in for those old regions they are not early reserved (by function early_reserve_memory), and the crashkernel memblock reservation will just treat them as usable memory and it could reserve the crashkernel region which overlaps with the old setup_data regions. And just like the bug I noticed here, kdump insert_resource failed because e820__reserve_resources has added the overlapped chunks in /proc/iomem already. Finally, looking at the code, the old setup_data regions are not used at all as no setup_data is passed in by the kexec boot loader. Although something like SETUP_PCI etc could be needed, kexec should pass the info as new setup_data so that kexec kernel can take care of them. This should be taken care of in other separate patches if needed. Thus drop the useless buggy code here. Signed-off-by:

This reverts commit 1601cd53 . This fix is applied globally to all devices, and it may change the existing control names. When the devices are managed with the fixed configuration like UCM, such control name mismatch may lead to significant regressions. For avoiding that kind of regression, we would need to apply such changes conditionally, but it'd take time to settle down. While the original fix is a good thing in general, in order to address the regression, let's revert the change for now.

When a CPU enters into idle and deactivates itself from the timer migration hierarchy without any global timer of its own to propagate, the group event of that CPU is set to "ignore" and tmigr_update_events() accordingly performs an early return without considering timers queued by other CPUs. If the hierarchy has a single level, and the CPU is the last one to enter idle, it will ignore others' global timers, as in the following layout: [GRP0:0] migrator = 0 active = 0 nextevt = T0i / \ 0 1 active (T0i) idle (T1) 0) CPU 0 is active thus its event is ignored (the letter 'i') and so are upper levels' events. CPU 1 is idle and has the timer T1 enqueued. [GRP0:0] migrator = NONE active = NONE nextevt = T0i / \ 0 1 idle (T0i) idle (T1) 1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is pushed as its next expiry and its own event kept as "ignore". As a result tmigr_update_events() ignores T1 and CPU 0 goes to idle with T1 unhandled. This isn't proper to single level hierarchy though. A similar issue, although slightly different, may arise on multi-level: [GRP1:0] migrator = GRP0:0 active = GRP0:0 nextevt = T0:0i, T0:1 / \ [GRP0:0] [GRP0:1] migrator = 0 migrator = NONE active = 0 active = NONE nextevt = T0i nextevt = T2 / \ / \ 0 (T0i) 1 (T1) 2 (T2) 3 active idle idle idle 0) CPU 0 is active thus its event is ignored (the letter 'i') and so are upper levels' events. CPU 1 is idle and has the timer T1 enqueued. CPU 2 also has a timer. The expiry order is T0 (ignored) < T1 < T2 [GRP1:0] migrator = GRP0:0 active = GRP0:0 nextevt = T0:0i, T0:1 / \ [GRP0:0] [GRP0:1] migrator = NONE migrator = NONE active = NONE active = NONE nextevt = T0i nextevt = T2 / \ / \ 0 (T0i) 1 (T1) 2 (T2) 3 idle idle idle idle 1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is pushed as its next expiry and its own event kept as "ignore". As a result tmigr_update_events() ignores T1. The change only propagated up to 1st level so far. [GRP1:0] migrator = NONE active = NONE nextevt = T0:1 / \ [GRP0:0] [GRP0:1] migrator = NONE migrator = NONE active = NONE active = NONE nextevt = T0i nextevt = T2 / \ / \ 0 (T0i) 1 (T1) 2 (T2) 3 idle idle idle idle 2) The change now propagates up to the top. tmigr_update_events() finds that the child event is ignored and thus removes it. The top level next event is now T2 which is returned to CPU 0 as its next effective expiry to take account for as the global idle migrator. However T1 has been ignored along the way, leaving it unhandled. Fix those issues with removing the buggy related early return. Ignored child events must not prevent from evaluating the other events within the same group. Reported-by:

Pull CXL updates from Dan Williams: "CXL has mechanisms to enumerate the performance characteristics of memory devices. Those mechanisms allow Linux to build the equivalent of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That capability is necessary because static ACPI can not represent dynamic CXL configurations (and reconfigurations). So, building on the v6.8 work to add "Quality of Service" enumeration, this update plumbs CXL "access coordinates" (read/write access latency and bandwidth) in all the same places that ACPI HMAT feeds similar data. Follow-on patches from the -mm side can then use that data to feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to drivers/base/. The other feature update this cycle is support for CXL error injection via the ACPI EINJ module. That facility enables injection of bus protocol errors provided the user knows the magic address values to insert in the interface. To hide that magic, and make this easier to use, new error injection attributes were added to CXL debugfs. That interface injects the errors relative to a CXL object rather than require user tooling to know how to lookup and inject RCRB (Root Complex Register Block) addresses into the raw EINJ debugfs interface. It received some helpful review comments from Tony, but no explicit acks from the ACPI side. The primary user visible change for existing EINJ users is that they may find that einj.ko was already loaded by cxl_core.ko. Previously, einj.ko was only loaded on demand. The usual collection of miscellaneous cleanups are also present this cycle.

This is inconsistent with the rest of the users of mirror_ds, which have if (IS_ERR_OR_NULL(mirror_ds)) to keep from tripping over this exact scenario. Fix this up in ff_layout_cancel_io() to make sure we don't panic when we get an error. I also spot checked all the other instances of checking mirror_ds and we appear to be doing the correct checks everywhere, only unconditionally dereferencing mirror_ds when we know it would be valid.

This reverts commits 99101dda and b80b701d. Linus reports that the sysreg reserved bit checks in KVM have led to build failures, arising from commit fdd867fe ("arm64/sysreg: Add register fields for ID_AA64DFR1_EL1") giving meaning to fields that were previously RES0. Of course, this is a genuine issue, since KVM's sysreg emulation depends heavily on the definition of reserved fields. But at this point the build breakage is far more offensive, and the right course of action is to revert and retry later. All of these build-time assertions were on by default before commit 99101dda ("KVM: arm64: Make build-time check of RES0/RES1 bits optional"), so deliberately revert it all atomically to avoid introducing further breakage of bisection.

Pull VFIO updates from Alex Williamson: - Add warning in unlikely case that device is not captured with driver_override (Kunwu Chan) - Error handling improvements in mlx5-vfio-pci to detect firmware tracking object error states, logging of firmware error syndrom, and releasing of firmware resources in aborted migration sequence (Yishai Hadas) - Correct an un-alphabetized VFIO MAINTAINERS entry (Alex Williamson) - Make the mdev_bus_type const and also make the class struct const for a couple of the vfio-mdev sample drivers (Ricardo B. Marliere) - Addition of a new vfio-pci variant driver for the GPU of NVIDIA's Grace-Hopper superchip. During initialization of the chip-to-chip interconnect in this hardware module, the PCI BARs of the device become unused in favor of a faster, coherent mechanism for exposing device memory. This driver primarily changes the VFIO representation of the device to masquerade this coherent aperture to replace the physical PCI BARs for userspace drivers. This also incorporates use of a new vma flag allowing KVM to use write combining attributes for uncached device memory (Ankit Agrawal) - Reset fixes and cleanups for the pds-vfio-pci driver. Save and restore files were previously leaked if the device didn't pass through an error state, this is resolved and later re-fixed to prevent access to the now freed files. Reset handling is also refactored to remove the complicated deferred reset mechanism (Brett Creeley) - Remove some references to pl330 in the vfio-platform amba driver (Geert Uytterhoeven) - Remove twice redundant and ugly code to unpin incidental pins of the zero-page (Alex Williamson) - Deferred reset logic is also removed from the hisi-acc-vfio-pci driver as a simplification (Shameer Kolothum) - Enforce that mlx5-vfio-pci devices must support PRE_COPY and remove resulting unnecessary code. There is no device firmware that has been available publicly without this support (Yishai Hadas) - Switch over to using the .remove_new callback for vfio-platform in support of the broader transition for a void remove function (Uwe Kleine-König) - Resolve multiple issues in interrupt code for VFIO bus drivers that allow calling eventfd_signal() on a NULL context. This also remove a potential race in INTx setup on certain hardware for vfio-pci, races with various mechanisms to mask INTx, and leaked virqfds in vfio-platform (Alex Williamson) * tag 'vfio-v6.9-rc1' of https://github.com/awilliam/linux-vfio: (29 commits) vfio/fsl-mc: Block calling interrupt handler without trigger vfio/platform: Create persistent IRQ handlers vfio/platform: Disable virqfds on cleanup vfio/pci: Create persistent INTx handler vfio: Introduce interface to flush virqfd inject workqueue vfio/pci: Lock external INTx masking ops vfio/pci: Disable auto-enable of exclusive INTx IRQ vfio/pds: Refactor/simplify reset logic vfio/pds: Make sure migration file isn't accessed after reset vfio/platform: Convert to platform remove callback returning void vfio/mlx5: Enforce PRE_COPY support vfio/mbochs: make mbochs_class constant vfio/mdpy: make mdpy_class constant hisi_acc_vfio_pci: Remove the deferred_reset logic Revert "vfio/type1: Unpin zero pages" vfio/nvgrace-gpu: Convey kvm to map device memory region as noncached vfio: amba: Rename pl330_ids[] to vfio_amba_ids[] vfio/pds: Always clear the save/restore FDs on reset vfio/nvgrace-gpu: Add vfio pci variant module for grace hopper vfio/pci: rename and export range_intersect_range ...

Pull kvm updates from Paolo Bonzini: "S390: - Changes to FPU handling came in via the main s390 pull request - Only deliver to the guest the SCLP events that userspace has requested - More virtual vs physical address fixes (only a cleanup since virtual and physical address spaces are currently the same) - Fix selftests undefined behavior x86: - Fix a restriction that the guest can't program a PMU event whose encoding matches an architectural event that isn't included in the guest CPUID. The enumeration of an architectural event only says that if a CPU supports an architectural event, then the event can be programmed *using the architectural encoding*. The enumeration does NOT say anything about the encoding when the CPU doesn't report support the event *in general*. It might support it, and it might support it using the same encoding that made it into the architectural PMU spec - Fix a variety of bugs in KVM's emulation of RDPMC (more details on individual commits) and add a selftest to verify KVM correctly emulates RDMPC, counter availability, and a variety of other PMC-related behaviors that depend on guest CPUID and therefore are easier to validate with selftests than with custom guests (aka kvm-unit-tests) - Zero out PMU state on AMD if the virtual PMU is disabled, it does not cause any bug but it wastes time in various cases where KVM would check if a PMC event needs to be synthesized - Optimize triggering of emulated events, with a nice ~10% performance improvement in VM-Exit microbenchmarks when a vPMU is exposed to the guest - Tighten the check for "PMI in guest" to reduce false positives if an NMI arrives in the host while KVM is handling an IRQ VM-Exit - Fix a bug where KVM would report stale/bogus exit qualification information when exiting to userspace with an internal error exit code - Add a VMX flag in /proc/cpuinfo to report 5-level EPT support - Rework TDP MMU root unload, free, and alloc to run with mmu_lock held for read, e.g. to avoid serializing vCPUs when userspace deletes a memslot - Tear down TDP MMU page tables at 4KiB granularity (used to be 1GiB). KVM doesn't support yielding in the middle of processing a zap, and 1GiB granularity resulted in multi-millisecond lags that are quite impolite for CONFIG_PREEMPT kernels - Allocate write-tracking metadata on-demand to avoid the memory overhead when a kernel is built with i915 virtualization support but the workloads use neither shadow paging nor i915 virtualization - Explicitly initialize a variety of on-stack variables in the emulator that triggered KMSAN false positives - Fix the debugregs ABI for 32-bit KVM - Rework the "force immediate exit" code so that vendor code ultimately decides how and when to force the exit, which allowed some optimization for both Intel and AMD - Fix a long-standing bug where kvm_has_noapic_vcpu could be left elevated if vCPU creation ultimately failed, causing extra unnecessary work - Cleanup the logic for checking if the currently loaded vCPU is in-kernel - Harden against underflowing the active mmu_notifier invalidation count, so that "bad" invalidations (usually due to bugs elsehwere in the kernel) are detected earlier and are less likely to hang the kernel x86 Xen emulation: - Overlay pages can now be cached based on host virtual address, instead of guest physical addresses. This removes the need to reconfigure and invalidate the cache if the guest changes the gpa but the underlying host virtual address remains the same - When possible, use a single host TSC value when computing the deadline for Xen timers in order to improve the accuracy of the timer emulation - Inject pending upcall events when the vCPU software-enables its APIC to fix a bug where an upcall can be lost (and to follow Xen's behavior) - Fall back to the slow path instead of warning if "fast" IRQ delivery of Xen events fails, e.g. if the guest has aliased xAPIC IDs RISC-V: - Support exception and interrupt handling in selftests - New self test for RISC-V architectural timer (Sstc extension) - New extension support (Ztso, Zacas) - Support userspace emulation of random number seed CSRs ARM: - Infrastructure for building KVM's trap configuration based on the architectural features (or lack thereof) advertised in the VM's ID registers - Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to x86's WC) at stage-2, improving the performance of interacting with assigned devices that can tolerate it - Conversion of KVM's representation of LPIs to an xarray, utilized to address serialization some of the serialization on the LPI injection path - Support for _architectural_ VHE-only systems, advertised through the absence of FEAT_E2H0 in the CPU's ID register - Miscellaneous cleanups, fixes, and spelling corrections to KVM and selftests LoongArch: - Set reserved bits as zero in CPUCFG - Start SW timer only when vcpu is blocking - Do not restart SW timer when it is expired - Remove unnecessary CSR register saving during enter guest - Misc cleanups and fixes as usual Generic: - Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically always true on all architectures except MIPS (where Kconfig determines the available depending on CPU capabilities). It is replaced either by an architecture-dependent symbol for MIPS, and IS_ENABLED(CONFIG_KVM) everywhere else - Factor common "select" statements in common code instead of requiring each architecture to specify it - Remove thoroughly obsolete APIs from the uapi headers - Move architecture-dependent stuff to uapi/asm/kvm.h - Always flush the async page fault workqueue when a work item is being removed, especially during vCPU destruction, to ensure that there are no workers running in KVM code when all references to KVM-the-module are gone, i.e. to prevent a very unlikely use-after-free if kvm.ko is unloaded - Grab a reference to the VM's mm_struct in the async #PF worker itself instead of gifting the worker a reference, so that there's no need to remember to *conditionally* clean up after the worker Selftests: - Reduce boilerplate especially when utilize selftest TAP infrastructure - Add basic smoke tests for SEV and SEV-ES, along with a pile of library support for handling private/encrypted/protected memory - Fix benign bugs where tests neglect to close() guest_memfd files" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (246 commits) selftests: kvm: remove meaningless assignments in Makefiles KVM: riscv: selftests: Add Zacas extension to get-reg-list test RISC-V: KVM: Allow Zacas extension for Guest/VM KVM: riscv: selftests: Add Ztso extension to get-reg-list test RISC-V: KVM: Allow Ztso extension for Guest/VM RISC-V: KVM: Forward SEED CSR access to user space KVM: riscv: selftests: Add sstc timer test KVM: riscv: selftests: Change vcpu_has_ext to a common function KVM: riscv: selftests: Add guest helper to get vcpu id KVM: riscv: selftests: Add exception handling support LoongArch: KVM: Remove unnecessary CSR register saving during enter guest LoongArch: KVM: Do not restart SW timer when it is expired LoongArch: KVM: Start SW timer only when vcpu is blocking LoongArch: KVM: Set reserved bits as zero in CPUCFG KVM: selftests: Explicitly close guest_memfd files in some gmem tests KVM: x86/xen: fix recursive deadlock in timer injection KVM: pfncache: simplify locking and make more self-contained KVM: x86/xen: remove WARN_ON_ONCE() with false positives in evtchn delivery KVM: x86/xen: inject vCPU upcall vector when local APIC is enabled KVM: x86/xen: improve accuracy of Xen timers ...

Pull i2c updates from Wolfram Sang: "Minor changes to the I2C core. Most changes are in drivers: The i801 and designware drivers received most of the changes, including refactorings and some additions. Recovery changes for the iMX and iMX-LPI2C are now utilizing the generic i2c support. The Cadence driver now supports system suspend and resume. The hisi, mpc, sh_mobile, and npcm drivers have undergone some cleanups and improvements. Meanwhile, Uwe continues his work on converting the "remove" callback to become a void function. The pca954x mux driver now supports additional configurations, such as isolating faulty channels and flushing stuck buses, among others. Support has been added for Renesas r8a779h0, i.MX95 LPI2C, and Microchip sam9x7.

Convert Samsung SoC Keypad bindings to DT schema with changes: 1. Rename "linux,keypad-no-autorepeat" property to "linux,input-no-autorepeat", because the latter was implemented in the Linux driver. 2. Add clocks and clock-names, already used by DTS and the Linux driver. Signed-off-by:
