2025-10-10ext4, doc: fix and improve directory hash tree descriptionZeno Endemann1-31/+32
Some of the details about how directory hash trees work were confusing or outright wrong, this patch should fix those. A note on dx_tail's dt_reserved member, as far as I can tell the kernel never sets this explicitly, so its content is apparently left-overs from what was there before (for the dx_root I've seen remnants of a ext4_dir_entry_tail struct from when the dir was not yet a hash dir).

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "There's a bunch of patches here across drivers/clk/ to migrate drivers to use struct clk_ops::determine_rate() instead of the round_rate() one so that we can remove the round_rate clk_op entirely. Brian has taken up that task which nobody else has wanted to do for close to a decade. Thanks Brian! This is all prerequisite work to get to the real task of improving the clk rate setting process. Once we have determine_rate() used everywhere, we'll be able to do things like chain the rate request structs in linked lists to order the rate setting operations or add more parameters without having to change every clk driver in existence. It's also nice to not have multiple ways to do something which just causes confusion for clk driver authors. Overall I'm glad this is getting done. Beyond this change we also have a tweak to the clk_lookup() function in the core framework to use hashing on the clk name instead of a clk tree walk with string comparisons. We _still_ rely on the clk name to be unique, because historically we've used globally unique strings to describe the clk tree topology. This tree walk becomes increasingly slow as more clks are added to the system. Searching from the roots for a duplicate is simple but pretty dumb and it wastes boot time so we're using a hash table as an improvement. Ideally we wouldn't rely on the strings to be unique at all, relegating them to simply debug information, but that is future work that will likely require some sort of Kconfig knob indicating strings aren't used for topology description. Outside of the core framework changes we have the usual new SoC support and fixes to clk drivers for things that were discovered once the clks were used by consumer drivers. Nothing in particular is jumping out at me in the "misc" pile, except maybe the Amlogic driver that has gone through a refactoring. That series got a fix from testing in -next though so it seems likely that things have been getting good test coverage for a couple weeks already" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (299 commits) clk: microchip: core: remove duplicate roclk_determine_rate() reset: aspeed: register AST2700 reset auxiliary bus device dt-bindings: clock: ast2700: modify soc0/1 clock define clk: tegra: do not overallocate memory for bpmp clocks clk: ep93xx: Use int type to store negative error codes clk: nxp: Fix pll0 rate check condition in LPC18xx CGU driver clk: loongson2: Add clock definitions for Loongson-2K0300 SoC clk: loongson2: Avoid hardcoding firmware name of the reference clock clk: loongson2: Allow zero divisors for dividers clk: loongson2: Support scale clocks with an alternative mode clk: loongson2: Allow specifying clock flags for gate clock dt-bindings: clock: loongson2: Add Loongson-2K0300 compatible clk: clocking-wizard: Fix output clock register offset for Versal platforms clk: xilinx: Optimize divisor search in clk_wzrd_get_divisors_ver() clk: mmp: pxa1908: Instantiate power driver through auxiliary bus clk: s2mps11: add support for S2MPG10 PMIC clock dt-bindings: clock: samsung,s2mps11: add s2mpg10 dt-bindings: stm32: cosmetic fixes for STM32MP25 clock and reset bindings clk: stm32: introduce clocks for STM32MP21 platform dt-bindings: stm32: add STM32MP21 clocks and reset bindings ...

It is worth noting that while SHSTK and IBT can be enabled separately in CPUID, it is not really possible to virtualize them separately. Therefore, Intel processors will really allow both SHSTK and IBT under the hood if either is made visible in the guest's CPUID. The alternative would be to intercept XSAVES/XRSTORS, which is not feasible for performance reasons - Fix a variety of fuzzing WARNs all caused by checking L1 intercepts when completing userspace I/O.

This feature splits the shared SEV-ES/SEV-SNP ASID space into separate ranges for SEV-ES and SEV-SNP guests, therefore a new module parameter is needed to control the number of ASIDs that can be used for VMs with CipherText Hiding vs. how many can be used to run SEV-ES guests - Add support for Secure TSC for SEV-SNP guests, which prevents the untrusted host from tampering with the guest's TSC frequency, while still allowing the the VMM to configure the guest's TSC frequency prior to launch - Validate the XCR0 provided by the guest (via the GHCB) to avoid bugs resulting from bogus XCR0 values - Save an SEV guest's policy if and only if LAUNCH_START fully succeeds to avoid leaving behind stale state (thankfully not consumed in KVM) - Explicitly reject non-positive effective lengths during SNP's LAUNCH_UPDATE instead of subtly relying on guest_memfd to deal with them - Reload the pre-VMRUN TSC_AUX on #VMEXIT for SEV-ES guests, not the host's desired TSC_AUX, to fix a bug where KVM was keeping a different vCPU's TSC_AUX in the host MSR until return to userspace KVM (Intel): - Preparation for FRED support - Don't retry in TDX's anti-zero-step mitigation if the target memslot is invalid, i.e. is being deleted or moved, to fix a deadlock scenario similar to the aforementioned prefaulting case - Misc bugfixes and minor cleanups" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (142 commits) KVM: x86: Export KVM-internal symbols for sub-modules only KVM: x86: Drop pointless exports of kvm_arch_xxx() hooks KVM: x86: Move kvm_intr_is_single_vcpu() to lapic.c KVM: Export KVM-internal symbols for sub-modules only KVM: s390/vfio-ap: Use kvm_is_gpa_in_memslot() instead of open coded equivalent KVM: VMX: Make CR4.CET a guest owned bit KVM: selftests: Verify MSRs are (not) in save/restore list when (un)supported KVM: selftests: Add coverage for KVM-defined registers in MSRs test KVM: selftests: Add KVM_{G,S}ET_ONE_REG coverage to MSRs test KVM: selftests: Extend MSRs test to validate vCPUs without supported features KVM: selftests: Add support for MSR_IA32_{S,U}_CET to MSRs test KVM: selftests: Add an MSR test to exercise guest/host and read/write KVM: x86: Define AMD's #HV, #VC, and #SX exception vectors KVM: x86: Define Control Protection Exception (#CP) vector KVM: x86: Add human friendly formatting for #XM, and #VE KVM: SVM: Enable shadow stack virtualization for SVM KVM: SEV: Synchronize MSR_IA32_XSS from the GHCB when it's valid KVM: SVM: Pass through shadow stack MSRs as appropriate KVM: SVM: Update dump_vmcb with shadow stack save area additions KVM: nSVM: Save/load CET Shadow Stack state to/from vmcb12/vmcb02 ...

git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci Pull pci updates from Bjorn Helgaas: "Enumeration: - Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that take config space accessor functions. Implement pci_find_capability(), pci_find_ext_capability(), and dwc, dwc endpoint, and cadence capability search interfaces with them (Hans Zhang) - Leave parent unit address 0 in 'interrupt-map' so that when we build devicetree nodes to describe PCI functions that contain multiple peripherals, we can build this property even when interrupt controllers lack 'reg' properties (Lorenzo Pieralisi) - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read Request Size to 128B to avoid a performance issue (Ilpo Järvinen) - Add sysfs 'serial_number' file to expose the Device Serial Number (Matthew Wood) - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das) Resource management: - Align m68k pcibios_enable_device() with other arches (Ilpo Järvinen) - Remove sparc pcibios_enable_device() implementations that don't do anything beyond what pci_enable_resources() does (Ilpo Järvinen) - Remove mips pcibios_enable_resources() and use pci_enable_resources() instead (Ilpo Järvinen) - Clean up bridge window sizing and assignment (Ilpo Järvinen), including: - Leave non-claimed bridge windows disabled - Enable bridges even if a window wasn't assigned because not all windows are required by downstream devices - Preserve bridge window type when releasing the resource, since the type is needed for reassignment - Consolidate selection of bridge windows into two new interfaces, pbus_select_window() and pbus_select_window_for_type(), so this is done consistently - Compute bridge window start and end earlier to avoid logging stale information MSI: - Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol Vives) Error handling: - Align AER with EEH by allowing drivers to request a Bus Reset on Non-Fatal Errors (in addition to the reset on Fatal Errors that we already do) (Lukas Wunner) - If error recovery fails, emit FAILED_RECOVERY uevents for the devices, not for the bridge leading to them. This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner) - Align AER with EEH by calling err_handler.error_detected() callbacks to notify drivers if error recovery fails (Lukas Wunner) - Align AER with EEH by restoring device error_state to pci_channel_io_normal before the err_handler.slot_reset() callback. This is earlier than before the err_handler.resume() callback (Lukas Wunner) - Emit a BEGIN_RECOVERY uevent when driver's err_handler.error_detected() requests a reset, as well as when it says recovery is complete or can be done without a reset (Niklas Schnelle) - Align s390 with AER and EEH by emitting uevents during error recovery (Niklas Schnelle) - Align EEH with AER and s390 by emitting BEGIN_RECOVERY, SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the result of err_handler.error_detected() (Niklas Schnelle) - Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES error information identifies a device without an AER Capability (Breno Leitao) - Update error decoding and TLP Log printing for new errors in current PCIe base spec (Lukas Wunner) - Update error recovery documentation to match the current code and use consistent nomenclature (Lukas Wunner) ASPM: - Enable all ClockPM and ASPM states for devicetree platforms, since there's typically no firmware that enables ASPM This is a risky change that may uncover hardware or configuration defects at boot-time rather than when users enable ASPM via sysfs later. Booting with "pcie_aspm=off" prevents this enabling (Manivannan Sadhasivam) - Remove the qcom code that enabled ASPM (Manivannan Sadhasivam) Power management: - If a device has already been disconnected, e.g., by a hotplug removal, don't bother trying to resume it to D0 when detaching the driver. This avoids annoying "Unable to change power state from D3cold to D0" messages (Mario Limonciello) - Ensure devices are powered up before config reads for 'max_link_width', 'current_link_speed', 'current_link_width', 'secondary_bus_number', and 'subordinate_bus_number' sysfs files. This prevents using invalid data (~0) in drivers or lspci and, depending on how the PCIe controller reports errors, may avoid error interrupts or crashes (Brian Norris) Virtualization: - Add rescan/remove locking when enabling/disabling SR-IOV, which avoids list corruption on s390, where disabling SR-IOV also generates hotplug events (Niklas Schnelle) Peer-to-peer DMA: - Free struct p2p_pgmap, not a member within it, in the pci_p2pdma_add_resource() error path (Sungho Kim) Endpoint framework: - Document sysfs interface for BAR assignment of vNTB endpoint functions (Jerome Brunet) - Fix array underflow in endpoint BAR test case (Dan Carpenter) - Skip endpoint IRQ test if the IRQ is out of range to avoid false errors (Christian Bruel) - Fix endpoint test case for controllers with fixed-size BARs smaller than requested by the test (Marek Vasut) - Restore inbound translation when disabling doorbell so the endpoint doorbell test case can be run more than once (Niklas Cassel) - Avoid a NULL pointer dereference when releasing DMA channels in endpoint DMA test case (Shin'ichiro Kawasaki) - Convert tegra194 interrupt number to MSI vector to fix endpoint Kselftest MSI_TEST test case (Niklas Cassel) - Reset tegra194 BARs when running in endpoint mode so the BAR tests don't overwrite the ATU settings in BAR4 (Niklas Cassel) - Handle errors in tegra194 BPMP transactions so we don't mistakenly skip future PERST# assertion (Vidya Sagar) AMD MDB PCIe controller driver: - Update DT binding example to separate PERST# to a Root Port stanza to make multiple Root Ports possible in the future (Sai Krishna Musham) - Add driver support for PERST# being described in a Root Port stanza, falling back to the host bridge if not found there (Sai Krishna Musham) Freescale i.MX6 PCIe controller driver: - Enable the 3.3V Vaux supply if available so devices can request wakeup with either Beacon or WAKE# (Richard Zhu) MediaTek PCIe Gen3 controller driver: - Add optional sys clock ready time setting to avoid sys_clk_rdy signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno) - Add DT binding and driver support for MT6991 and MT8196 (AngeloGioacchino Del Regno) NVIDIA Tegra PCIe controller driver: - When asserting PERST#, disable the controller instead of mistakenly disabling the PLL twice (Nagarjuna Kristam) - Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock nesting error (Marek Vasut) Qualcomm PCIe controller driver: - Select PCI Power Control Slot driver so slot voltage rails can be turned on/off if described in Root Port devicetree node (Qiang Yu) - Parse only PCI bridge child nodes in devicetree, skipping unrelated nodes such as OPP (Operating Performance Points), which caused probe failures (Krishna Chaitanya Chundru) - Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang) - Consolidate Root Port 'phy' and 'reset' properties in struct qcom_pcie_port, regardless of whether we got them from the Root Port node or the host bridge node (Manivannan Sadhasivam) - Fetch and map the ELBI register space in the DWC core rather than in each driver individually (Krishna Chaitanya Chundru) - Enable ECAM mechanism in DWC core by setting up iATU with 'CFG Shift Feature' and use this in the qcom driver (Krishna Chaitanya Chundru) - Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya Chundru) - Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm Glymur, which is compatible with X1E80100 but doesn't have the cnoc_sf_axi clock (Qiang Yu) Renesas R-Car PCIe controller driver: - Fix a typo that prevented correct PHY initialization (Marek Vasut) - Add a missing 1ms delay after PWR reset assertion as required by the V4H manual (Marek Vasut) - Assure reset has completed before DBI access to avoid SError (Marek Vasut) - Fix inverted PHY initialization check, which sometimes led to timeouts and failure to start the controller (Marek Vasut) - Pass the correct IRQ domain to generic_handle_domain_irq() to fix a regression when converting to msi_create_parent_irq_domain() (Claudiu Beznea) - Drop the spinlock protecting the PMSR register - it's no longer required since pci_lock already serializes accesses (Marek Vasut) - Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock nesting error (Marek Vasut) SOPHGO PCIe controller driver: - Check for existence of struct cdns_pcie.ops before using it to allow Cadence drivers that don't need to supply ops (Chen Wang) - Add DT binding and driver for the SOPHGO SG2042 PCIe controller (Chen Wang) STMicroelectronics STM32MP25 PCIe controller driver: - Update pinctrl documentation of initial states and use in runtime suspend/resume (Christian Bruel) - Add pinctrl_pm_select_init_state() for use by stm32 driver, which needs it during resume (Christian Bruel) - Add devicetree bindings and drivers for the STMicroelectronics STM32MP25 in host and endpoint modes (Christian Bruel) Synopsys DesignWare PCIe controller driver: - Add support for x16 in devicetree 'num-lanes' property (Konrad Dybcio) - Verify that if DT specifies a single IRQ for all eDMA channels, it is named 'dma' (Niklas Cassel) TI J721E PCIe driver: - Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth Vadapalli) - Power controller off before configuring the glue layer so the controller latches the correct values on power-on (Siddharth Vadapalli) TI Keystone PCIe controller driver: - Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver exits with error (Siddharth Vadapalli) - Add Peripheral Virtualization Unit (PVU), which restricts DMA from PCIe devices to specific regions of host memory, to the ti,am65 binding (Jan Kiszka) Xilinx NWL PCIe controller driver: - Clear bootloader E_ECAM_CONTROL before merging in the new driver value to avoid writing invalid values (Jani Nurminen)" * tag 'pci-v6.18-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (141 commits) PCI/AER: Avoid NULL pointer dereference in aer_ratelimit() MAINTAINERS: Add entry for ST STM32MP25 PCIe drivers PCI: stm32-ep: Add PCIe Endpoint support for STM32MP25 dt-bindings: PCI: Add STM32MP25 PCIe Endpoint bindings PCI: stm32: Add PCIe host support for STM32MP25 PCI: xilinx-nwl: Fix ECAM programming PCI: j721e: Fix incorrect error message in probe() PCI: keystone: Use devm_request_irq() to free "ks-pcie-error-irq" on exit dt-bindings: PCI: qcom,pcie-x1e80100: Set clocks minItems for the fifth Glymur PCIe Controller PCI: dwc: Support 16-lane operation PCI: Add lockdep assertion in pci_stop_and_remove_bus_device() PCI/IOV: Add PCI rescan-remove locking when enabling/disabling SR-IOV PCI: rcar-host: Convert struct rcar_msi mask_lock into raw spinlock PCI: tegra194: Rename 'root_bus' to 'root_port_bus' in tegra_pcie_downstream_dev_to_D0() PCI: tegra: Convert struct tegra_msi mask_lock into raw spinlock PCI: rcar-gen4: Fix inverted break condition in PHY initialization PCI: rcar-gen4: Assure reset occurs before DBI access PCI: rcar-gen4: Add missing 1ms delay after PWR reset assertion PCI: Set up bridge resources earlier PCI: rcar-host: Drop PMSR spinlock ...

Loads of different stuff in here, it was a busy development cycle in lots of different subsystems, with over 27k new lines added to the tree.

I'll be enabling these back on in the build in the usb.git tree after -rc1 is out so that developers can continue to work on these in linux-next over the next development cycle. - Android Binder driver implemented in Rust. This is the big one, and was driving a huge majority of the rust binding work over the past years. Right now there are two binder drivers in the kernel, selected only at build time as to which one to use as binder wants to be included in the system at boot time. The binder C maintainers all agreed on this, as eventually, they want the C code to be removed from the tree, but it will take a few releases to get there while both are maintained to ensure that the rust implementation is fully stable and compliant with the existing userspace apis.

git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull more RISC-V updates from Paul Walmsley: - Support for the RISC-V-standardized RPMI interface. RPMI is a platform management communication mechanism between OSes running on application processors, and a remote platform management processor. Similar to ARM SCMI, TI SCI, etc. This includes irqchip, mailbox, and clk changes. - Support for the RISC-V-standardized MPXY SBI extension. MPXY is a RISC-V-specific standard implementing a shared memory mailbox between S-mode operating systems (e.g., Linux) and M-mode firmware (e.g., OpenSBI). It is part of this PR since one of its use cases is to enable M-mode firmware to act as a single RPMI client for all RPMI activity on a core (including S-mode RPMI activity). Includes a mailbox driver. - Some ACPI-related updates to enable the use of RPMI and MPXY. - The addition of Linux-wide memcpy_{from,to}_le32() static inline functions, for RPMI use. - An ACPI Kconfig change to enable boot logos on any ACPI-using architecture (including RISC-V) - A RISC-V defconfig change to add GPIO keyboard and event device support, for front panel shutdown or reboot buttons * tag 'riscv-for-linus-6.18-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (26 commits) clk: COMMON_CLK_RPMI should depend on RISCV ACPI: support BGRT table on RISC-V MAINTAINERS: Add entry for RISC-V RPMI and MPXY drivers RISC-V: Enable GPIO keyboard and event device in RV64 defconfig irqchip/riscv-rpmi-sysmsi: Add ACPI support mailbox/riscv-sbi-mpxy: Add ACPI support irqchip/irq-riscv-imsic-early: Export imsic_acpi_get_fwnode() ACPI: RISC-V: Add RPMI System MSI to GSI mapping ACPI: RISC-V: Add support to update gsi range ACPI: RISC-V: Create interrupt controller list in sorted order ACPI: scan: Update honor list for RPMI System MSI ACPI: Add support for nargs_prop in acpi_fwnode_get_reference_args() ACPI: property: Refactor acpi_fwnode_get_reference_args() to support nargs_prop irqchip: Add driver for the RPMI system MSI service group dt-bindings: Add RPMI system MSI interrupt controller bindings dt-bindings: Add RPMI system MSI message proxy bindings clk: Add clock driver for the RISC-V RPMI clock service group dt-bindings: clock: Add RPMI clock service controller bindings dt-bindings: clock: Add RPMI clock service message proxy bindings mailbox: Add RISC-V SBI message proxy (MPXY) based mailbox driver ...

Pull kvm updates from Paolo Bonzini: "This excludes the bulk of the x86 changes, which I will send separately. They have two not complex but relatively unusual conflicts so I will wait for other dust to settle. guest_memfd: - Add support for host userspace mapping of guest_memfd-backed memory for VM types that do NOT use support KVM_MEMORY_ATTRIBUTE_PRIVATE (which isn't precisely the same thing as CoCo VMs, since x86's SEV-MEM and SEV-ES have no way to detect private vs. shared). This lays the groundwork for removal of guest memory from the kernel direct map, as well as for limited mmap() for guest_memfd-backed memory. For more information see: - commit a6ad54137af9 ("Merge branch 'guest-memfd-mmap' into HEAD") - guest_memfd in Firecracker: https://github.com/firecracker-microvm/firecracker/tree/feature/secret-hiding - direct map removal: https://lore.kernel.org/all/20250221160728.1584559-1-roypat@amazon.co.uk/ - mmap support: https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/ ARM: - Add support for FF-A 1.2 as the secure memory conduit for pKVM, allowing more registers to be used as part of the message payload. - Change the way pKVM allocates its VM handles, making sure that the privileged hypervisor is never tricked into using uninitialised data. - Speed up MMIO range registration by avoiding unnecessary RCU synchronisation, which results in VMs starting much quicker. - Add the dump of the instruction stream when panic-ing in the EL2 payload, just like the rest of the kernel has always done. This will hopefully help debugging non-VHE setups. - Add 52bit PA support to the stage-1 page-table walker, and make use of it to populate the fault level reported to the guest on failing to translate a stage-1 walk. - Add NV support to the GICv3-on-GICv5 emulation code, ensuring feature parity for guests, irrespective of the host platform. - Fix some really ugly architecture problems when dealing with debug in a nested VM. This has some bad performance impacts, but is at least correct. - Add enough infrastructure to be able to disable EL2 features and give effective values to the EL2 control registers. This then allows a bunch of features to be turned off, which helps cross-host migration. - Large rework of the selftest infrastructure to allow most tests to transparently run at EL2. This is the first step towards enabling NV testing. - Various fixes and improvements all over the map, including one BE fix, just in time for the removal of the feature. LoongArch: - Detect page table walk feature on new hardware - Add sign extension with kernel MMIO/IOCSR emulation - Improve in-kernel IPI emulation - Improve in-kernel PCH-PIC emulation - Move kvm_iocsr tracepoint out of generic code RISC-V: - Added SBI FWFT extension for Guest/VM with misaligned delegation and pointer masking PMLEN features - Added ONE_REG interface for SBI FWFT extension - Added Zicbop and bfloat16 extensions for Guest/VM - Enabled more common KVM selftests for RISC-V - Added SBI v3.0 PMU enhancements in KVM and perf driver s390: - Improve interrupt cpu for wakeup, in particular the heuristic to decide which vCPU to deliver a floating interrupt to. - Clear the PTE when discarding a swapped page because of CMMA; this bug was introduced in 6.16 when refactoring gmap code. x86 selftests: - Add #DE coverage in the fastops test (the only exception that's guest- triggerable in fastop-emulated instructions). - Fix PMU selftests errors encountered on Granite Rapids (GNR), Sierra Forest (SRF) and Clearwater Forest (CWF). - Minor cleanups and improvements x86 (guest side): - For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when overriding guest MTRR for TDX/SNP to fix an issue where ACPI auto-mapping could map devices as WB and prevent the device drivers from mapping their devices with UC/UC-. - Make kvm_async_pf_task_wake() a local static helper and remove its export. - Use native qspinlocks when running in a VM with dedicated vCPU=>pCPU bindings even when PV_UNHALT is unsupported. Generic: - Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as __GFP_NOWARN is now included in GFP_NOWAIT. * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (178 commits) KVM: s390: Fix to clear PTE when discarding a swapped page KVM: arm64: selftests: Cover ID_AA64ISAR3_EL1 in set_id_regs KVM: arm64: selftests: Remove a duplicate register listing in set_id_regs KVM: arm64: selftests: Cope with arch silliness in EL2 selftest KVM: arm64: selftests: Add basic test for running in VHE EL2 KVM: arm64: selftests: Enable EL2 by default KVM: arm64: selftests: Initialize HCR_EL2 KVM: arm64: selftests: Use the vCPU attr for setting nr of PMU counters KVM: arm64: selftests: Use hyp timer IRQs when test runs at EL2 KVM: arm64: selftests: Select SMCCC conduit based on current EL KVM: arm64: selftests: Provide helper for getting default vCPU target KVM: arm64: selftests: Alias EL1 registers to EL2 counterparts KVM: arm64: selftests: Create a VGICv3 for 'default' VMs KVM: arm64: selftests: Add unsanitised helpers for VGICv3 creation KVM: arm64: selftests: Add helper to check for VGICv3 support KVM: arm64: selftests: Initialize VGICv3 only once KVM: arm64: selftests: Provide kvm_arch_vm_post_create() in library code KVM: selftests: Add ex_str() to print human friendly name of exception vectors selftests/kvm: remove stale TODO in xapic_state_test KVM: selftests: Handle Intel Atom errata that leads to PMU event overcount ...
