"Arm:
- Fix trapping regression when no in-kernel irqchip is present
- Check host-provided, untrusted ranges and offsets in pKVM
- Fix regression restoring the ID_PFR1_EL1 register
- Fix vgic ITS locking issues when LPIs are not directly injected
Arm selftests:
- Correct target CPU programming in vgic_lpi_stress selftest
- Fix exposure of SCTLR2_EL2 and ZCR_EL2 in get-reg-list selftest
RISC-V:
- Fix check for local interrupts on riscv32
- Read HGEIP CSR on the correct cpu when checking for IMSIC
interrupts
- Remove automatic I/O mapping from kvm_arch_prepare_memory_region()
x86:
- Inject #UD if the guest attempts to execute SEAMCALL or TDCALL as
KVM doesn't support virtualization the instructions, but the
instructions are gated only by VMXON. That is, they will VM-Exit
instead of taking a #UD and until now this resulted in KVM exiting
to userspace with an emulation error.
- Unload the "FPU" when emulating INIT of XSTATE features if and only
if the FPU is actually loaded, instead of trying to predict when
KVM will emulate an INIT (CET support missed the MP_STATE path).
Add sanity checks to detect and harden against similar bugs in the
future.
- Unregister KVM's GALog notifier (for AVIC) when kvm-amd.ko is
unloaded.
- Use a raw spinlock for svm->ir_list_lock as the lock is taken
during schedule(), and "normal" spinlocks are sleepable locks when
PREEMPT_RT=y.
- Remove guest_memfd bindings on memslot deletion when a gmem file is
dying to fix a use-after-free race found by syzkaller.
- Fix a goof in the EPT Violation handler where KVM checks the wrong
variable when determining if the reported GVA is valid.
- Fix and simplify the handling of LBR virtualization on AMD, which
was made buggy and unnecessarily complicated by nested VM support
Misc:
- Update Oliver's email address"

riscv: asm: use .insn for making custom instructions
The assembler has .insn for building custom instructions now, so change the .4byte to .insn. This ensures the output is marked as an instruction and not as data which may confuse both debuggers and anything else that relies on this sort of marking.

riscv: Fix memory leak in module_frob_arch_sections()
The current code directly overwrites the scratch pointer with the return value of kvrealloc(). If kvrealloc() fails and returns NULL, the original buffer becomes unreachable, causing a memory leak. Fix this by using a temporary variable to store kvrealloc()'s return value and only update the scratch pointer on success. Found via static anlaysis and this is similar to commit |

riscv: ptdump: use seq_puts() in pt_dump_seq_puts() macro
The pt_dump_seq_puts() macro incorrectly uses seq_printf() instead of seq_puts(). This is both a performance issue and conceptually wrong, as the macro name suggests plain string output (puts) but the implementation uses formatted output (printf). The macro is used in ptdump.c:301 to output a newline character. Using seq_printf() adds unnecessary overhead for format string parsing when outputting this constant string.

riscv: hwprobe: avoid uninitialized variable use in hwprobe_arch_id()
Resolve this smatch warning:
arch/riscv/kernel/sys_hwprobe.c:50 hwprobe_arch_id() error: uninitialized symbol 'cpu_id'.
This could happen if hwprobe_arch_id() was called with a key ID of
something other than MVENDORID, MIMPID, and MARCHID. This does not
happen in the current codebase. The only caller of hwprobe_arch_id()
is a function that only passes one of those three key IDs.
For the sake of reducing static analyzer warning noise, and in the
unlikely event that hwprobe_arch_id() is someday called with some
other key ID, validate hwprobe_arch_id()'s input to ensure that
'cpu_id' is always initialized before use.

riscv: cpufeature: avoid uninitialized variable in has_thead_homogeneous_vlenb()
In has_thead_homogeneous_vlenb(), smatch detected that the vlenb variable
could be used while uninitialized. It appears that this could happen if
no CPUs described in DT have the "thead,vlenb" property.
Fix by initializing vlenb to 0, which will keep thead_vlenb_of set to 0
(as it was statically initialized). This in turn will cause
riscv_v_setup_vsize() to fall back to CSR probing - the desired result if
thead,vlenb isn't provided in the DT data.
While here, fix a nearby comment typo.

riscv: hwprobe: Fix stale vDSO data for late-initialized keys at boot
The hwprobe vDSO data for some keys, like MISALIGNED_VECTOR_PERF,
is determined by an asynchronous kthread. This can create a race
condition where the kthread finishes after the vDSO data has
already been populated, causing userspace to read stale values.
To fix this race, a new 'ready' flag is added to the vDSO data,
initialized to 'false' during arch_initcall_sync. This flag is
checked by both the vDSO's user-space code and the riscv_hwprobe
syscall. The syscall serves as a one-time gate, using a completion
to wait for any pending probes before populating the data and
setting the flag to 'true', thus ensuring userspace reads fresh
values on its first request.

RISC-V: Define pgprot_dmacoherent() for non-coherent devices
The pgprot_dmacoherent() is used when allocating memory for
non-coherent devices and by default pgprot_dmacoherent() is
same as pgprot_noncached() unless architecture overrides it.
Currently, there is no pgprot_dmacoherent() definition for
RISC-V hence non-coherent device memory is being mapped as
IO thereby making CPU access to such memory slow.
Define pgprot_dmacoherent() to be same as pgprot_writecombine()
for RISC-V so that CPU access non-coherent device memory as
NOCACHE which is better than accessing it as IO.

RISC-V: KVM: Read HGEIP CSR on the correct cpu
When executing kvm_riscv_vcpu_aia_has_interrupts, the vCPU may have
migrated and the IMSIC VS-file have not been updated yet, currently
the HGEIP CSR should be read from the imsic->vsfile_cpu ( the pCPU
before migration ) via on_each_cpu_mask, but this will trigger an
IPI call and repeated IPI within a period of time is expensive in
a many-core systems.
Just let the vCPU execute and update the correct IMSIC VS-file via
kvm_riscv_vcpu_aia_imsic_update may be a simple solution.

RISC-V: clear hot-unplugged cores from all task mm_cpumasks to avoid rfence errors
openSBI v1.7 adds harts checks for ipi operations. Especially it adds comparison between hmask passed as an argument from linux and mask of online harts (from openSBI side). If they don't fit each other the error occurs. When cpu is offline, cpu_online_mask is explicitly cleared in __cpu_disable. However, there is no explicit clearing of mm_cpumask. mm_cpumask is used for rfence operations that call openSBI RFENCE extension which uses ipi to remote harts. If hart is offline there may be error if mask of linux is not as mask of online harts in openSBI. this patch adds explicit clearing of mm_cpumask for offline hart.

riscv: kgdb: Ensure that BUFMAX > NUMREGBYTES
The current value of BUFMAX is similar as in other architectures, but as per documentation on KGDB (see 'Documentation/process/debugging/kgdb.rst'), BUFMAX has to be larger than NUMREGBYTES. Some NUMREGBYTES architectures (e.g. powerpc or hexagon) actually define BUFMAX in relation to NUMREGBYTES, and thus this condition is always guaranteed. Since 2048 is a value that is generally accepted on all architectures, and that is larger than the current value of NUMREGBYTES, we can keep this value in arch/riscv, but we can at least add an 'static_assert' as an extra measure just in case NUMREGBYTES changes in the future for some unforseen reason.

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

system".
It's a long story - the [1/N] changelog spells out the considerations
- "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on

Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is
administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication

Pull SoC dt updates from Arnd Bergmann:
"There are five sets of new SoCs that get added in existing families,
all of them being either upgrades or cut-down versions of the older
chips:
- Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
of high-end workstations and laptops from Apple. Linux has been
working on these for a while but stil requires patches.
- Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
unlike the earlier Armv7 Artpec6 from the same company that was
part of a separate family of chips.
- NXP i.MX91 is a cut-down version of i.MX93, using only a single
Cortex-A55 core.
- Qualcomm Lemans Auto is a variant of the Lemans SoC that was
originally merged under the sa8775p name, the differences being
mostly the firmware configuration of the platform.
- Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial
bedded SoCs based on Cortex-A55 cores
In total, there are 65 new machines, including:
- Industrial embedded system and single-board computers based on NXP,
Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.
- Reference boards for the newly added Renesas, Qualcomm, NXP and
Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC
- Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
chips.
- Several Samsung phones using Qualcomm Snapdragon chips
- Set-top boxes based on Allwinner H313
- Five BMC boards using 32-bit ASpeed SoCs
- Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708
(ARMv7) SoCs
Two machines get phased out because they were available only in small
quantities but never made it into products: one STi407 based reference
board, and a Snapdragon 845 based Chromebook.
Aside from the newly added machines, a lot of work went into improving
hardware support on the existing machines and cleaning up contents for
validation"

Merge tag 'irq-drivers-2025-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq chip driver updates from Thomas Gleixner: - Use the startup/shutdown callbacks for the PCI/MSI per device interrupt domains. This allows us to initialize the RISCV PLIC interrupt hierarchy correctly and provides a mechanism to decouple the masking and unmasking during run-time from the expensive PCI mask and unmask when the underlying MSI provider implementation allows the interrupt to be masked. - Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that the affinity assignment works correctly by switching it over to the startup/shutdown scheme - Allow MSI providers to opt out from masking a PCI/MSI interrupt at the PCI device during operation when the provider can mask the interrupt at the underlying interrupt chip. This reduces the overhead in scenarios where disable_irq()/enable_irq() is utilized frequently by a driver. The PCI/MSI device level [un]masking is only required on startup and shutdown in this case. - Remove the conditional mask/unmask logic in the PCI/MSI layer as this is now handled unconditionally. - Replace the hardcoded interrupt routing in the Loongson EIOINTC interrupt driver to respect the firmware settings and spread them out to different CPU interrupt inputs so that the demultiplexing handler only needs to read only a single 64-bit status register instead of four, which significantly reduces the overhead in VMs as the status register access causes a VM exit. - Add support for the new AST2700 SCU interrupt controllers - Use the legacy interrupt domain setup for the Loongson PCH-LPC interrupt controller, which resembles the x86 legacy PIC setup and has the same hardcoded legacy requirements. - The usual set of cleanups, fixes and improvements all over the place * tag 'irq-drivers-2025-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (25 commits) irqchip/loongson-pch-lpc: Use legacy domain for PCH-LPC IRQ controller PCI/MSI: Remove the conditional parent [un]mask logic irqchip/msi-lib: Honor the MSI_FLAG_PCI_MSI_MASK_PARENT flag irqchip/aspeed-scu-ic: Add support for AST2700 SCU interrupt controllers dt-bindings: interrupt-controller: aspeed: Add AST2700 SCU IC compatibles dt-bindings: mfd: aspeed: Add AST2700 SCU compatibles irqchip/aspeed-scu-ic: Refactor driver to support variant-based initialization irqchip/gic-v5: Fix error handling in gicv5_its_irq_domain_alloc() irqchip/gic-v5: Fix loop in gicv5_its_create_itt_two_level() cleanup path irqchip/gic-v5: Delete a stray tab irqchip/sg2042-msi: Set irq type according to DT configuration riscv: sophgo: dts: sg2044: Change msi irq type to IRQ_TYPE_EDGE_RISING riscv: sophgo: dts: sg2042: Change msi irq type to IRQ_TYPE_EDGE_RISING irqchip/gic-v2m: Handle Multiple MSI base IRQ Alignment irqchip/renesas-rzg2l: Remove dev_err_probe() if error is -ENOMEM irqchip: Use int type to store negative error codes irqchip/gic-v5: Remove the redundant ITS cache invalidation PCI/MSI: Check MSI_FLAG_PCI_MSI_MASK_PARENT in cond_[startup|shutdown]_parent() irqchip/loongson-eiointc: Add multiple interrupt pin routing support irqchip/loongson-eiointc: Route interrupt parsed from bios table ... |

entry: Rename "kvm" entry code assets to "virt" to genericize APIs
Rename the "kvm" entry code files and Kconfigs to use generic "virt" nomenclature so that the code can be reused by other hypervisors (or rather, their root/dom0 partition drivers), without incorrectly suggesting the code somehow relies on and/or involves KVM. No functional change intended.

entry/kvm: KVM: Move KVM details related to signal/-EINTR into KVM proper
Move KVM's morphing of pending signals into userspace exits into KVM proper, and drop the @vcpu param from xfer_to_guest_mode_handle_work(). How KVM responds to -EINTR is a detail that really belongs in KVM itself, and invoking kvm_handle_signal_exit() from kernel code creates an inverted module dependency. E.g. attempting to move kvm_handle_signal_exit() into kvm_main.c would generate an linker error when building kvm.ko as a module. Dropping KVM details will also converting the KVM "entry" code into a more generic virtualization framework so that it can be used when running as a Hyper-V root partition. Lastly, eliminating usage of "struct kvm_vcpu" outside of KVM is also nice to have for KVM x86 developers, as keeping the details of kvm_vcpu purely within KVM allows changing the layout of the structure without having to boot into a new kernel, e.g. allows rebuilding and reloading kvm.ko with a modified kvm_vcpu structure as part of debug/development.
