Luis Gerhorst	d6f1c85f22	bpf: Fall back to nospec for Spectre v1 ... This implements the core of the series and causes the verifier to fall back to mitigating Spectre v1 using speculation barriers. The approach was presented at LPC'24 [1] and RAID'24 [2]. If we find any forbidden behavior on a speculative path, we insert a nospec (e.g., lfence speculation barrier on x86) before the instruction and stop verifying the path. While verifying a speculative path, we can furthermore stop verification of that path whenever we encounter a nospec instruction. A minimal example program would look as follows: A = true B = true if A goto e f() if B goto e unsafe() e: exit There are the following speculative and non-speculative paths (`cur->speculative` and `speculative` referring to the value of the push_stack() parameters): - A = true - B = true - if A goto e - A && !cur->speculative && !speculative - exit - !A && !cur->speculative && speculative - f() - if B goto e - B && cur->speculative && !speculative - exit - !B && cur->speculative && speculative - unsafe() If f() contains any unsafe behavior under Spectre v1 and the unsafe behavior matches `state->speculative && error_recoverable_with_nospec(err)`, do_check() will now add a nospec before f() instead of rejecting the program: A = true B = true if A goto e nospec f() if B goto e unsafe() e: exit Alternatively, the algorithm also takes advantage of nospec instructions inserted for other reasons (e.g., Spectre v4). Taking the program above as an example, speculative path exploration can stop before f() if a nospec was inserted there because of Spectre v4 sanitization. In this example, all instructions after the nospec are dead code (and with the nospec they are also dead code speculatively). For this, it relies on the fact that speculation barriers generally prevent all later instructions from executing if the speculation was not correct: * On Intel x86_64, lfence acts as full speculation barrier, not only as a load fence [3]: An LFENCE instruction or a serializing instruction will ensure that no later instructions execute, even speculatively, until all prior instructions complete locally. [...] Inserting an LFENCE instruction after a bounds check prevents later operations from executing before the bound check completes. This was experimentally confirmed in [4]. * On AMD x86_64, lfence is dispatch-serializing [5] (requires MSR C001_1029[1] to be set if the MSR is supported, this happens in init_amd()). AMD further specifies "A dispatch serializing instruction forces the processor to retire the serializing instruction and all previous instructions before the next instruction is executed" [8]. As dispatch is not specific to memory loads or branches, lfence therefore also affects all instructions there. Also, if retiring a branch means it's PC change becomes architectural (should be), this means any "wrong" speculation is aborted as required for this series. * ARM's SB speculation barrier instruction also affects "any instruction that appears later in the program order than the barrier" [6]. * PowerPC's barrier also affects all subsequent instructions [7]: [...] executing an ori R31,R31,0 instruction ensures that all instructions preceding the ori R31,R31,0 instruction have completed before the ori R31,R31,0 instruction completes, and that no subsequent instructions are initiated, even out-of-order, until after the ori R31,R31,0 instruction completes. The ori R31,R31,0 instruction may complete before storage accesses associated with instructions preceding the ori R31,R31,0 instruction have been performed Regarding the example, this implies that `if B goto e` will not execute before `if A goto e` completes. Once `if A goto e` completes, the CPU should find that the speculation was wrong and continue with `exit`. If there is any other path that leads to `if B goto e` (and therefore `unsafe()`) without going through `if A goto e`, then a nospec will still be needed there. However, this patch assumes this other path will be explored separately and therefore be discovered by the verifier even if the exploration discussed here stops at the nospec. This patch furthermore has the unfortunate consequence that Spectre v1 mitigations now only support architectures which implement BPF_NOSPEC. Before this commit, Spectre v1 mitigations prevented exploits by rejecting the programs on all architectures. Because some JITs do not implement BPF_NOSPEC, this patch therefore may regress unpriv BPF's security to a limited extent: * The regression is limited to systems vulnerable to Spectre v1, have unprivileged BPF enabled, and do NOT emit insns for BPF_NOSPEC. The latter is not the case for x86 64- and 32-bit, arm64, and powerpc 64-bit and they are therefore not affected by the regression. According to commit a6f6a95f25 ("LoongArch, bpf: Fix jit to skip speculation barrier opcode"), LoongArch is not vulnerable to Spectre v1 and therefore also not affected by the regression. * To the best of my knowledge this regression may therefore only affect MIPS. This is deemed acceptable because unpriv BPF is still disabled there by default. As stated in a previous commit, BPF_NOSPEC could be implemented for MIPS based on GCC's speculation_barrier implementation. * It is unclear which other architectures (besides x86 64- and 32-bit, ARM64, PowerPC 64-bit, LoongArch, and MIPS) supported by the kernel are vulnerable to Spectre v1. Also, it is not clear if barriers are available on these architectures. Implementing BPF_NOSPEC on these architectures therefore is non-trivial. Searching GCC and the kernel for speculation barrier implementations for these architectures yielded no result. * If any of those regressed systems is also vulnerable to Spectre v4, the system was already vulnerable to Spectre v4 attacks based on unpriv BPF before this patch and the impact is therefore further limited. As an alternative to regressing security, one could still reject programs if the architecture does not emit BPF_NOSPEC (e.g., by removing the empty BPF_NOSPEC-case from all JITs except for LoongArch where it appears justified). However, this will cause rejections on these archs that are likely unfounded in the vast majority of cases. In the tests, some are now successful where we previously had a false-positive (i.e., rejection). Change them to reflect where the nospec should be inserted (using __xlated_unpriv) and modify the error message if the nospec is able to mitigate a problem that previously shadowed another problem (in that case __xlated_unpriv does not work, therefore just add a comment). Define SPEC_V1 to avoid duplicating this ifdef whenever we check for nospec insns using __xlated_unpriv, define it here once. This also improves readability. PowerPC can probably also be added here. However, omit it for now because the BPF CI currently does not include a test. Limit it to EPERM, EACCES, and EINVAL (and not everything except for EFAULT and ENOMEM) as it already has the desired effect for most real-world programs. Briefly went through all the occurrences of EPERM, EINVAL, and EACCESS in verifier.c to validate that catching them like this makes sense.

Luis Gerhorst	dff883d9e9	bpf, arm64, powerpc: Change nospec to include v1 barrier ... This changes the semantics of BPF_NOSPEC (previously a v4-only barrier) to always emit a speculation barrier that works against both Spectre v1 AND v4. If mitigation is not needed on an architecture, the backend should set bpf_jit_bypass_spec_v4/v1(). As of now, this commit only has the user-visible implication that unpriv BPF's performance on PowerPC is reduced. This is the case because we have to emit additional v1 barrier instructions for BPF_NOSPEC now. This commit is required for a future commit to allow us to rely on BPF_NOSPEC for Spectre v1 mitigation. As of this commit, the feature that nospec acts as a v1 barrier is unused. Commit f5e81d1117 ("bpf: Introduce BPF nospec instruction for mitigating Spectre v4") noted that mitigation instructions for v1 and v4 might be different on some archs. While this would potentially offer improved performance on PowerPC, it was dismissed after the following considerations: * Only having one barrier simplifies the verifier and allows us to easily rely on v4-induced barriers for reducing the complexity of v1-induced speculative path verification. * For the architectures that implemented BPF_NOSPEC, only PowerPC has distinct instructions for v1 and v4. Even there, some insns may be shared between the barriers for v1 and v4 (e.g., 'ori 31,31,0' and 'sync'). If this is still found to impact performance in an unacceptable way, BPF_NOSPEC can be split into BPF_NOSPEC_V1 and BPF_NOSPEC_V4 later. As an optimization, we can already skip v1/v4 insns from being emitted for PowerPC with this setup if bypass_spec_v1/v4 is set. Vulnerability-status for BPF_NOSPEC-based Spectre mitigations (v4 as of this commit, v1 in the future) is therefore: * x86 (32-bit and 64-bit), ARM64, and PowerPC (64-bit): Mitigated - This patch implements BPF_NOSPEC for these architectures. The previous v4-only version was supported since commit f5e81d1117 ("bpf: Introduce BPF nospec instruction for mitigating Spectre v4") and commit b7540d6250 ("powerpc/bpf: Emit stf barrier instruction sequences for BPF_NOSPEC"). * LoongArch: Not Vulnerable - Commit a6f6a95f25 ("LoongArch, bpf: Fix jit to skip speculation barrier opcode") is the only other past commit related to BPF_NOSPEC and indicates that the insn is not required there. * MIPS: Vulnerable (if unprivileged BPF is enabled) - Commit a6f6a95f2580 ("LoongArch, bpf: Fix jit to skip speculation barrier opcode") indicates that it is not vulnerable, but this contradicts the kernel and Debian documentation. Therefore, I assume that there exist vulnerable MIPS CPUs (but maybe not from Loongson?). In the future, BPF_NOSPEC could be implemented for MIPS based on the GCC speculation_barrier [1]. For now, we rely on unprivileged BPF being disabled by default. * Other: Unknown - To the best of my knowledge there is no definitive information available that indicates that any other arch is vulnerable. They are therefore left untouched (BPF_NOSPEC is not implemented, but bypass_spec_v1/v4 is also not set). I did the following testing to ensure the insn encoding is correct: * ARM64: * 'dsb nsh; isb' was successfully tested with the BPF CI in [2] * 'sb' locally using QEMU v7.2.15 -cpu max (emitted sb insn is executed for example with './test_progs -t verifier_array_access') * PowerPC: The following configs were tested locally with ppc64le QEMU v8.2 '-machine pseries -cpu POWER9': * STF_BARRIER_EIEIO + CONFIG_PPC_BOOK32_64 * STF_BARRIER_SYNC_ORI (forced on) + CONFIG_PPC_BOOK32_64 * STF_BARRIER_FALLBACK (forced on) + CONFIG_PPC_BOOK32_64 * CONFIG_PPC_E500 (forced on) + STF_BARRIER_EIEIO * CONFIG_PPC_E500 (forced on) + STF_BARRIER_SYNC_ORI (forced on) * CONFIG_PPC_E500 (forced on) + STF_BARRIER_FALLBACK (forced on) * CONFIG_PPC_E500 (forced on) + STF_BARRIER_NONE (forced on) Most of those cobinations should not occur in practice, but I was not able to get an PPC e6500 rootfs (for testing PPC_E500 without forcing it on). In any case, this should ensure that there are no unexpected conflicts between the insns when combined like this. Individual v1/v4 barriers were already emitted elsewhere. Hari's ack is for the PowerPC changes only.

Luis Gerhorst	03c68a0f8c	bpf, arm64, powerpc: Add bpf_jit_bypass_spec_v1/v4() ... JITs can set bpf_jit_bypass_spec_v1/v4() if they want the verifier to skip analysis/patching for the respective vulnerability. For v4, this will reduce the number of barriers the verifier inserts. For v1, it allows more programs to be accepted. The primary motivation for this is to not regress unpriv BPF's performance on ARM64 in a future commit where BPF_NOSPEC is also used against Spectre v1. This has the user-visible change that v1-induced rejections on non-vulnerable PowerPC CPUs are avoided. For now, this does not change the semantics of BPF_NOSPEC. It is still a v4-only barrier and must not be implemented if bypass_spec_v4 is always true for the arch. Changing it to a v1 AND v4-barrier is done in a future commit. As an alternative to bypass_spec_v1/v4, one could introduce NOSPEC_V1 AND NOSPEC_V4 instructions and allow backends to skip their lowering as suggested by commit f5e81d1117 ("bpf: Introduce BPF nospec instruction for mitigating Spectre v4"). Adding bpf_jit_bypass_spec_v1/v4() was found to be preferable for the following reason: * bypass_spec_v1/v4 benefits non-vulnerable CPUs: Always performing the same analysis (not taking into account whether the current CPU is vulnerable), needlessly restricts users of CPUs that are not vulnerable. The only use case for this would be portability-testing, but this can later be added easily when needed by allowing users to force bypass_spec_v1/v4 to false. * Portability is still acceptable: Directly disabling the analysis instead of skipping the lowering of BPF_NOSPEC(_V1/V4) might allow programs on non-vulnerable CPUs to be accepted while the program will be rejected on vulnerable CPUs. With the fallback to speculation barriers for Spectre v1 implemented in a future commit, this will only affect programs that do variable stack-accesses or are very complex. For PowerPC, the SEC_FTR checking in bpf_jit_bypass_spec_v4() is based on the check that was previously located in the BPF_NOSPEC case. For LoongArch, it would likely be safe to set both bpf_jit_bypass_spec_v1() and _v4() according to commit a6f6a95f2580 ("LoongArch, bpf: Fix jit to skip speculation barrier opcode"). This is omitted here as I am unable to do any testing for LoongArch. Hari's ack concerns the PowerPC part only.

Yonghong Song	1209339844	bpf: Implement mprog API on top of existing cgroup progs ... Current cgroup prog ordering is appending at attachment time. This is not ideal. In some cases, users want specific ordering at a particular cgroup level. To address this, the existing mprog API seems an ideal solution with supporting BPF_F_BEFORE and BPF_F_AFTER flags. But there are a few obstacles to directly use kernel mprog interface. Currently cgroup bpf progs already support prog attach/detach/replace and link-based attach/detach/replace. For example, in struct bpf_prog_array_item, the cgroup_storage field needs to be together with bpf prog. But the mprog API struct bpf_mprog_fp only has bpf_prog as the member, which makes it difficult to use kernel mprog interface. In another case, the current cgroup prog detach tries to use the same flag as in attach. This is different from mprog kernel interface which uses flags passed from user space. So to avoid modifying existing behavior, I made the following changes to support mprog API for cgroup progs: - The support is for prog list at cgroup level. Cross-level prog list (a.k.a. effective prog list) is not supported. - Previously, BPF_F_PREORDER is supported only for prog attach, now BPF_F_PREORDER is also supported by link-based attach. - For attach, BPF_F_BEFORE/BPF_F_AFTER/BPF_F_ID/BPF_F_LINK is supported similar to kernel mprog but with different implementation. - For detach and replace, use the existing implementation. - For attach, detach and replace, the revision for a particular prog list, associated with a particular attach type, will be updated by increasing count by 1.

Retain old deprecated symbols for compatibility, except for the pwrctrl slot driver (PCI_PWRCTRL_SLOT) (Johan Hovold) - When unregistering pwrctrl, cancel outstanding rescan work before cleaning up data structures to avoid use-after-free issues (Brian Norris) Bandwidth control: - Simplify link bandwidth controller by replacing the count of Link Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN flag (Ilpo Järvinen) - Update the Link Speed after retraining, since the Link Speed may have changed (Ilpo Järvinen) PCIe native device hotplug: - Ignore Presence Detect Changed caused by DPC. pciehp already ignores Link Down/Up events caused by DPC, but on slots using in-band presence detect, DPC causes a spurious Presence Detect Changed event (Lukas Wunner) - Ignore Link Down/Up caused by Secondary Bus Reset. On hotplug ports using in-band presence detect, the reset causes a Presence Detect Changed event, which mistakenly caused teardown and re-enumeration of the device. Drivers may need to annotate code that resets their device (Lukas Wunner) Virtualization: - Add an ACS quirk for Loongson Root Ports that don't advertise ACS but don't allow peer-to-peer transactions between Root Ports; the quirk allows each Root Port to be in a separate IOMMU group (Huacai Chen) Endpoint framework: - For fixed-size BARs, retain both the actual size and the possibly larger size allocated to accommodate iATU alignment requirements (Jerome Brunet) - Simplify ctrl/SPAD space allocation and avoid allocating more space than needed (Jerome Brunet) - Correct MSI-X PBA offset calculations for DesignWare and Cadence endpoint controllers (Niklas Cassel) - Align the return value (number of interrupts) encoding for pci_epc_get_msi()/pci_epc_ops::get_msi() and pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel) - Align the nr_irqs parameter encoding for pci_epc_set_msi()/pci_epc_ops::set_msi() and pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel) Common host controller library: - Convert pci-host-common to a library so platforms that don't need native host controller drivers don't need to include these helper functions (Manivannan Sadhasivam) Apple PCIe controller driver: - Extract ECAM bridge creation helper from pci_host_common_probe() to separate driver-specific things like MSI from PCI things (Marc Zyngier) - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with varying capabilities (Marc Zyngier) - Skip ports disabled in DT when setting up ports (Janne Grunau) - Add t6020 compatible string (Alyssa Rosenzweig) - Add T602x PCIe support (Hector Martin) - Directly set/clear INTx mask bits because T602x dropped the accessors that could do this without locking (Marc Zyngier) - Move port PHY registers to their own reg items to accommodate T602x, which moves them around; retain default offsets for existing DTs that lack phy%d entries with the reg offsets (Hector Martin) - Stop polling for core refclk, which doesn't work on T602x and the bootloader has already done anyway (Hector Martin) - Use gpiod_set_value_cansleep() when asserting PERST# in probe because we're allowed to sleep there (Hector Martin) Cadence PCIe controller driver: - Drop a runtime PM 'put' to resolve a runtime atomic count underflow (Hans Zhang) - Make the cadence core buildable as a module (Kishon Vijay Abraham I) - Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by loadable drivers when they are removed (Siddharth Vadapalli) Freescale i.MX6 PCIe controller driver: - Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP (Richard Zhu) - Remove redundant dw_pcie_wait_for_link() from imx_pcie_start_link(); since the DWC core does this, imx6 only needs it when retraining for a faster link speed (Richard Zhu) - Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu) - Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in some cases, the controller can't exit 'L23 Ready' through Beacon or PERST# deassertion (Richard Zhu) - Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum: controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8 GT/s, causing timeouts in L1 (Richard Zhu) - Wait for i.MX95 PLL lock before enabling controller (Richard Zhu) - Save/restore i.MX95 LUT for suspend/resume (Richard Zhu) Mobiveil PCIe controller driver: - Return bool (not int) for link-up check in mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans Zhang) NVIDIA Tegra194 PCIe controller driver: - Create debugfs directory for 'aspm_state_cnt' only when CONFIG_PCIEASPM is enabled, since there are no other entries (Hans Zhang) Qualcomm PCIe controller driver: - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane equalization presets (Krishna Chaitanya Chundru) - Read Maximum Link Width from the Link Capabilities register if DT lacks 'num-lanes' property (Krishna Chaitanya Chundru) - Add Physical Layer 64 GT/s Capability ID and register offsets for 8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya Chundru) - Add generic dwc support for configuring lane equalization presets (Krishna Chaitanya Chundru) - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar) Renesas R-Car PCIe controller driver: - Describe endpoint BAR 4 as being fixed size (Jerome Brunet) - Document how to obtain R-Car V4H (r8a779g0) controller firmware (Yoshihiro Shimoda) Rockchip PCIe controller driver: - Reorder rockchip_pci_core_rsts because reset_control_bulk_deassert() deasserts in reverse order, to fix a link training regression (Jensen Huang) - Mark RK3399 as being capable of raising INTx interrupts (Niklas Cassel) Rockchip DesignWare PCIe controller driver: - Check only PCIE_LINKUP, not LTSSM status, to determine whether the link is up (Shawn Lin) - Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s for Root Complex and Endpoint modes (Shawn Lin) - Hide the broken ATS Capability in rockchip_pcie_ep_init() instead of rockchip_pcie_ep_pre_init() so it stays hidden after PERST# resets non-sticky registers (Shawn Lin) - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit() (Diederik de Haas) Synopsys DesignWare PCIe controller driver: - Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training more robust;

Steven Rostedt	a4a45a9a72	fsdax: Remove unused trace events for dax insert mapping ... When the dax_fault_actor() helper was factored out, it removed the calls to the dax_pmd_insert_mapping and dax_insert_mapping events but never removed the events themselves. As each event created takes up memory (roughly 5K each), this is a waste as it is never used. Remove the unused dax_pmd_insert_mapping and dax_insert_mapping trace events.

regulator support for the BCM59054 Samsung S2MPG10: - Add support for the S2MPG10 PMIC, which communicates via the Samsung ACPM firmware instead of I2C Exynos ACPM: - Improve timeout detection reliability by using ktime APIs instead of a loop counter assumption - Allow PMIC access during late system shutdown by switching to 'udelay()' instead of a sleeping function - Fix an issue where reading command results longer than 8 bytes would fail - Silence non-error '-EPROBE_DEFER' messages during boot to clean up logs Exynos LPASS: - Fix an error handling path by switching to 'devm_regmap_init_mmio()' to prevent resource leaks - Fix a bug where 'exynos_lpass_disable()' was called twice in the remove function - Fix another resource leak in the probe's error path by using 'devm_add_action_or_reset()' Samsung SEC: - Handle the s2dos05, which does not have IRQ support, explicitly to prevent warnings - Fix the core driver to correctly handle errors from 'sec_irq_init()' instead of ignoring them STMPE-SPI: - Correct an undeclared identifier in the 'MODULE_DEVICE_TABLE' macro MAINTAINERS: - Adjust a file path for the Siemens IPC LED drivers entry to fix a broken

'sec-acpm') modules to support non-I2C devices - Merge the 'sec-core' and 'sec-irq' modules to reduce memory consumption - Move internal APIs to a private header to clean up the public API - Improve code style by sorting includes, cleaning up headers, sorting device tables, and using helper macros like 'dev_err_probe()', 'MFD_CELL', and 'REGMAP_IRQ_REG' - Make regmap configuration for s2dos05/s2mpu05 explicit to improve clarity - Rework platform data and regmap instantiation to use OF match data instead of a large switch statement ROHM BD96801/2: - Prepare the driver for new models

regulator driver to store descriptions in a table to ease support for new chips - Rename BCM59056-specific data to prepare for the addition of other regulators - Use 'dev_err_probe()' for cleaner error handling Exynos ACPM: - Correct kerneldoc warnings and use the conventional 'np' argument name General MFD: - Convert 'aat2870' and 'tps65010' to use the per-client debugfs directory provided by the I2C core - Convert 'sm501', 'tps65010' and 'ucb1x00' to use the new GPIO line value setter callbacks - Constify 'regmap_irq_chip' and other structures in '88pm886' to move data to read-only

Linus Torvalds	4c3b7df784	A big core MTD change is the introduction of a new class to always ... register a master device. This is a problem that has been there forever: the "master" device was not always present depending on a number of heuristics such as the presence of fixed partitions and the absence of a Kconfig symbol to force its presence. This was a problem for runtime PM operations which might not have the "master" device available in all situation. The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible. Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP table fixups for Macronix MX25L3255E have been merged. Aside from this, there is the usual load of misc improvement, fixes, and yaml conversion. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmg91NEACgkQJWrqGEe9 VoR8egf+JPTtykQ+Bip9bHStgfpxi0+OKL81PUuPBsbs5C546u5t6ZRhoPsU+KqL ZTyUk3ys7HcSwZCuiS9V6ea6TNV1FvAVZm+ONpkuPnU60++z8YfVr8ZvtgT0IUXx COi+5ksdsTFZMyRG+VybRKnYNrTYB7j7CqVL8ifxq1XYWnYdhjy5PH4DgAKnBhGL 523kN2eR85AhvJ4aulsKbcqQQYKvJIQbhjAKklA3yQVarDmoOdiSmndoZlRy+MDu B9DaRMvRRa/g1nI0stvR9K7FtdSrMYTg4kowR9jPRx0zEZXFFsZbASgcC+3G7HdK 7rLFWrN+G6fitcEjeAnfyV+sKF48LA== =tW1t -----END PGP SIGNATURE----- Merge tag 'mtd/for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull MTD updates from Miquel Raynal: "A big core MTD change is the introduction of a new class to always register a master device.

Steven Rostedt	e27e43a5cb	xdp: Remove unused mem_return_failed event ... The change to allow page_pool to handle its own page destruction instead of relying on XDP removed the trace_mem_return_failed() tracepoint caller, but did not remove the mem_return_failed trace event. As trace events take up memory when they are created regardless of if they are used or not, having this unused event around wastes around 5K of memory. Remove the unused event.

Miquel Raynal	aa70292325	The SPI NAND subsystem has seen the introduction of DTR operations (the ... equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible. Aside from this, there is the usual load of misc improvement and fixes. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmg90ysACgkQJWrqGEe9 VoTK8gf/U+28sdthNVHENmeQwgzMdjAaZkEn0qftRVplPUTGSqvkrTBQ2tsyGVpj V2jJ85WzQ6c+YVRjUsgojX4JClh0tfNrm8ySSu3TOAv98E/sCFttQgyCbELtt6GL P4/1g/BqHlagi1ouU95AtH3njZX9qXBq9cQGz3ZWX+qeS0p52wPsj1G8iy6syBR+ M6GZI92iINSXJUBlFBXzijDSxqcLWsAg8P2E5dTyL9Ukjcju0+fSQtt1oCp1F50+ zXJHfj3mB+BtBnX6nGhMu3sqY7LaM2NpEq7k6xtvo9ivWZwFAOK+uc31iGvAcKaZ R1A72QkRE3e0vQZjrX1JKZvXMVXt4Q== =Uj/O -----END PGP SIGNATURE----- Merge tag 'nand/for-6.16' into mtd/next The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names.

PCI logging should not use pci_printk() but pci_*() wrappers that follow the usual logging wrapper patterns. Remove pci_printk().

Paolo Bonzini	61374cc145	KVM/arm64 fixes for 6.16, take #1 ... - Make the irqbypass hooks resilient to changes in the GSI<->MSI routing, avoiding behind stale vLPI mappings being left behind. The fix is to resolve the VGIC IRQ using the host IRQ (which is stable) and nuking the vLPI mapping upon a routing change. - Close another VGIC race where vCPU creation races with VGIC creation, leading to in-flight vCPUs entering the kernel w/o private IRQs allocated. - Fix a build issue triggered by the recently added workaround for Ampere's AC04_CPU_23 erratum. - Correctly sign-extend the VA when emulating a TLBI instruction potentially targeting a VNCR mapping. - Avoid dereferencing a NULL pointer in the VGIC debug code, which can happen if the device doesn't have any mapping yet. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmg5fbgACgkQI9DQutE9 ekNMyhAAq99rswsyqUrDwTd4qwJBtRYj4FMkBD8rH1oPQcXkqPGVllOMOgAnJhtd mU1/XpU8gk49nsx5kwdg1RORQG4lKCZATH1F2MhInDWMMSSWUTWBu0+qG62GFQWF Db+aXcvyebHdfzunDmT1/NebhV9VGCnkUtbQrFBvBbqOt1xNCRhKNvv5RWNEugTW R2DIg4gCk2x1/iZceP8dDRDpnvFk8txtzZsWE6g1DZRw1mmlrz01rRgD7EJtkyaQ c74mqpc/A2GuJv2mwpz3GCXTLiNgAuNq1X9+yeEqYM+VVvuyGy906BTFXxgvYl6l o4OvE1F6QOtcJIokPb5kBlpxz76J2bNxKuUrY7rxM73Of0ZgGMsSltQxdcoGhJZ7 cyfUWFVQ+H5Gx+BVs/+5u2XdtX7OC0U50eXP0XrzviunTkEUhvRaH1WfTh9Zike/ U150d0oU17MeVZ9HlOWyhXV/nId6CPX5xo7BUjIq2e1Oy4mYkIYYbowdrV5t6NiJ FHwzXNa/T0prZDSPW4t1GL/8o8hcnd4KRGLTJDWBYk58J6S1hHG0QElAz5RvqUj+ nf8HSycZMBrpdXtIK6nu/GRk9Ng+6gT4KHomwjgIDj6QVn7DTFFId911j+HRmoCP DiV4QD4yVRSMBDX5cdQj2XBk2raMTOxdN9A1y6T2H3b+iLavVyo= =JjTn -----END PGP SIGNATURE----- Merge tag 'kvmarm-fixes-6.16-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 fixes for 6.16, take #1 - Make the irqbypass hooks resilient to changes in the GSI<->MSI routing, avoiding behind stale vLPI mappings being left behind.
