KVM: arm64: Move SVCR into the sysreg array
SVCR is just a system register, and has no purpose being outside of the sysreg array. If anything, it only makes it more difficult to eventually support SME one day. If ever. Move it into the array with its little friends, and associate it with a visibility predicate. Although this is dead code, it at least paves the way for the next set of FP-related extensions.

RISC-V Patches for the 6.11 Merge Window, Part 2
* Support for NUMA (via SRAT and SLIT), console output (via SPCR), and cache info (via PPTT) on ACPI-based systems. * The trap entry/exit code no longer breaks the return address stack predictor on many systems, which results in an improvement to trap latency. * Support for HAVE_ARCH_STACKLEAK. * The sv39 linear map has been extended to support 128GiB mappings. * The frequency of the mtime CSR is now visible via hwprobe. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmaj2EYTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiVG3D/9kNHTI09iPDJd6fTChE3cpMxy7xXXE URX3Avu+gYsJmIbYyg4RnQ8FGFN7icKBCrQqs7JmLliU0NU+YMcCcjsJA2QaivbD VAlaex1qNcvNGteHrpbqhr3Zs4zw8GlBkB3KFTLyPAp61bybGo0a/A5ONJ7ScQIW RWHewAPgb86cQ0Q34JpO87TqvMM0KMvhQP5dip+olaFjLRBzhXmGFZfHqA80kTWl 0ytYclVCHZMtO/5mnQpuIOVs1IKw9L4wa0sivOQF0iLTqfKDFALa6yZsThHA/w3e JVuBAdQhcPZ3fgO2fUfJPlW16GmRC2/tdiFg5NFw8k4vo7DYBwX55ztPKXqDrJDM 8ah85IeLiPar/A/uHdn6bPjK+aGMuzklKF50r62XXAc2fL8mza1sdvKCVOy2EOLn JyGI9c/10KpvN/DW8g7hPefhvbx4+tCKkFcPqf++VQha6W8cQdCKi+Li0Pm8TTnp XPQjIvSlDDG1Pl4ofgBSFoyB8pkBXNzvv8NZp+YYtnqSOLAKaZuP+KwA8TwHdvGM pdCXcL3KHiLy4/pJWEoNTutD0mbJ7PUIb2P/KkjqYDgp4F1n0Hg+/aeSIp+7a4Pv yTBctIGxrlriQMIdtWCR8tyhcPP4pDpGYkW0K15EE16G0NK0fjD89LEXYqT6ae2R C0QgiwnVe/eopg== =zeUn -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-6.11-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull more RISC-V updates from Palmer Dabbelt: - Support for NUMA (via SRAT and SLIT), console output (via SPCR), and cache info (via PPTT) on ACPI-based systems. - The trap entry/exit code no longer breaks the return address stack predictor on many systems, which results in an improvement to trap latency. - Support for HAVE_ARCH_STACKLEAK. - The sv39 linear map has been extended to support 128GiB mappings. - The frequency of the mtime CSR is now visible via hwprobe. * tag 'riscv-for-linus-6.11-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (21 commits) RISC-V: Provide the frequency of time CSR via hwprobe riscv: Extend sv39 linear mapping max size to 128G riscv: enable HAVE_ARCH_STACKLEAK riscv: signal: Remove unlikely() from WARN_ON() condition riscv: Improve exception and system call latency RISC-V: Select ACPI PPTT drivers riscv: cacheinfo: initialize cacheinfo's level and type from ACPI PPTT riscv: cacheinfo: remove the useless input parameter (node) of ci_leaf_init() RISC-V: ACPI: Enable SPCR table for console output on RISC-V riscv: boot: remove duplicated targets line trace: riscv: Remove deprecated kprobe on ftrace support riscv: cpufeature: Extract common elements from extension checking riscv: Introduce vendor variants of extension helpers riscv: Add vendor extensions to /proc/cpuinfo riscv: Extend cpufeature.c to detect vendor extensions RISC-V: run savedefconfig for defconfig RISC-V: hwprobe: sort EXT_KEY()s in hwprobe_isa_ext0() alphabetically ACPI: NUMA: replace pr_info with pr_debug in arch_acpi_numa_init ACPI: NUMA: change the ACPI_NUMA to a hidden option ACPI: NUMA: Add handler for SRAT RINTC affinity structure ... |

arm64: allow installing compressed image by default
On arm64 we build compressed images, but "make install" by default will install the old non-compressed one. To actually get the compressed image install, you need to use "make zinstall", which is not the usual way to install a kernel. Which may not sound like much of an issue, but when you deal with multiple architectures (and years of your fingers knowing the regular "make install" incantation), this inconsistency is pretty annoying. But as Will Deacon says: "Sadly, bootloaders being as top quality as you might expect, I don't think we're in a position to rely on decompressor support across the board. Our Image.gz is literally just that -- we don't have a built-in decompressor (nor do I think we want to rush into that again after the fun we had on arm32) and the recent EFI zboot support solves that problem for platforms using EFI. Changing the default 'install' target terrifies me. There are bound to be folks with embedded boards who've scripted this and we could really ruin their day if we quietly give them a compressed kernel that their bootloader doesn't know how to handle :/" So make this conditional on a new "COMPRESSED_INSTALL" option.

arm64: mm: Fix lockless walks with static and dynamic page-table folding
Lina reports random oopsen originating from the fast GUP code when
16K pages are used with 4-level page-tables, the fourth level being
folded at runtime due to lack of LPA2.
In this configuration, the generic implementation of
p4d_offset_lockless() will return a 'p4d_t *' corresponding to the
'pgd_t' allocated on the stack of the caller, gup_fast_pgd_range().
This is normally fine, but when the fourth level of page-table is folded
at runtime, pud_offset_lockless() will offset from the address of the
'p4d_t' to calculate the address of the PUD in the same page-table page.
This results in a stray stack read when the 'p4d_t' has been allocated
on the stack and can send the walker into the weeds.
Fix the problem by providing our own definition of p4d_offset_lockless()
when CONFIG_PGTABLE_LEVELS <= 4 which returns the real page-table
pointer rather than the address of the local stack variable.

* Code formatting was adjusted in xfs_sysctl.c to comply with code
conventions. The xfs_stats_clear_proc_handler,
xfs_panic_mask_proc_handler and xfs_deprecated_dointvec_minmax where
adjusted.
* The ctl_table argument in proc_watchdog_common was const qualified.
This is called from a proc_handler itself and is calling back into
another proc_handler, making it necessary to change it as part of the
proc_handler migration.

arm64/vdso: Remove --hash-style=sysv
glibc added support for .gnu.hash in 2006 and .hash has been obsoleted
for more than one decade in many Linux distributions. Using
--hash-style=sysv might imply unaddressed issues and confuse readers.
Just drop the option and rely on the linker default, which is likely
"both", or "gnu" when the distribution really wants to eliminate sysv
hash overhead.

Updates for the interrupt subsystem:
- Core:
- Provide a new mechanism to create interrupt domains. The existing
interfaces have already too many parameters and it's a pain to expand
any of this for new required functionality.
The new function takes a pointer to a data structure as argument. The
data structure combines all existing parameters and allows for easy
extension.
The first extension for this is to handle the instantiation of
generic interrupt chips at the core level and to allow drivers to
provide extra init/exit callbacks.
This is necessary to do the full interrupt chip initialization before
the new domain is published, so that concurrent usage sites won't see
a half initialized interrupt domain. Similar problems exist on
teardown.
This has turned out to be a real problem due to the deferred and
parallel probing which was added in recent years.
Handling this at the core level allows to remove quite some accrued
boilerplate code in existing drivers and avoids horrible workarounds
at the driver level.
- The usual small improvements all over the place
- Drivers
- Add support for LAN966x OIC and RZ/Five SoC
- Split the STM ExtI driver into a microcontroller and a SMP version to
allow building the latter as a module for multi-platform kernels.
- Enable MSI support for Armada 370XP on platforms which do not support
IPIs.
- The usual small fixes and enhancements all over the place.

Merge patch series "Add ACPI NUMA support for RISC-V"
Haibo Xu <haibo1.xu@intel.com> says:
This patch series enable RISC-V ACPI NUMA support which was based on
the recently approved ACPI ECR[1].
Patch 1/4 add RISC-V specific acpi_numa.c file to parse NUMA information
from SRAT and SLIT ACPI tables.
Patch 2/4 add the common SRAT RINTC affinity structure handler.
Patch 3/4 change the ACPI_NUMA to a hidden option since it would be selected
by default on all supported platform.
Patch 4/4 replace pr_info with pr_debug in arch_acpi_numa_init() to avoid
potential boot noise on ACPI platforms that are not NUMA.
Based-on: https://github.com/linux-riscv/linux-riscv/tree/for-next
[1] https://drive.google.com/file/d/1YTdDx2IPm5IeZjAW932EYU-tUtgS08tX/view?usp=sharing
Testing:
Since the ACPI AIA/PLIC support patch set is still under upstream review,
hence it is tested using the poll based HVC SBI console and RAM disk.

Yu has a fix which I'll send along later via the hotfixes branch. - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code. These fixes are also targetted at -stable kernels. - Ryusuke Konishi's series "nilfs2: fix potential issues related to reserved inodes" does that. This should actually be in the mm-nonmm-stable tree, along with the many other nilfs2 patches. My bad. - More folio conversions from Kefeng Wang in the series "mm: convert to folio_alloc_mpol()" - Kemeng Shi has sent some cleanups to the writeback code in the series "Add helper functions to remove repeated code and improve readability of cgroup writeback" - Kairui Song has made the swap code a little smaller and a little faster in the series "mm/swap: clean up and optimize swap cache index". - In the series "mm/memory: cleanly support zeropage in vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David Hildenbrand has reworked the rather sketchy handling of the use of the zeropage in MAP_SHARED mappings. I don't see any runtime effects here - more a cleanup/understandability/maintainablity thing. - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of higher addresses, for aarch64. The (poorly named) series is "Restructure va_high_addr_switch". - The core TLB handling code gets some cleanups and possible slight optimizations in Bang Li's series "Add update_mmu_tlb_range() to simplify code". - Jane Chu has improved the handling of our fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the series "Enhance soft hwpoison handling and injection". - Jeff Johnson has sent a billion patches everywhere to add MODULE_DESCRIPTION() to everything. Some landed in this pull. - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has simplified migration's use of hardware-offload memory copying. - Yosry Ahmed performs more folio API conversions in his series "mm: zswap: trivial folio conversions". - In the series "large folios swap-in: handle refault cases first", Chuanhua Han inches us forward in the handling of large pages in the swap code. This is a cleanup and optimization, working toward the end objective of full support of large folio swapin/out. - In the series "mm,swap: cleanup VMA based swap readahead window calculation", Huang Ying has contributed some cleanups and a possible fixlet to his VMA based swap readahead code. - In the series "add mTHP support for anonymous shmem" Baolin Wang has taught anonymous shmem mappings to use multisize THP. By default this is a no-op - users must opt in vis sysfs controls. Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Is anyone reading this stuff? If so, email me! - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers.

ARM:
* Initial infrastructure for shadow stage-2 MMUs, as part of nested virtualization enablement * Support for userspace changes to the guest CTR_EL0 value, enabling (in part) migration of VMs between heterogenous hardware * Fixes + improvements to pKVM's FF-A proxy, adding support for v1.1 of the protocol * FPSIMD/SVE support for nested, including merged trap configuration and exception routing * New command-line parameter to control the WFx trap behavior under KVM * Introduce kCFI hardening in the EL2 hypervisor * Fixes + cleanups for handling presence/absence of FEAT_TCRX * Miscellaneous fixes + documentation updates LoongArch: * Add paravirt steal time support. * Add support for KVM_DIRTY_LOG_INITIALLY_SET. * Add perf kvm-stat support for loongarch. RISC-V: * Redirect AMO load/store access fault traps to guest * perf kvm stat support * Use guest files for IMSIC virtualization, when available ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA extensions is coming through the RISC-V tree. s390: * Assortment of tiny fixes which are not time critical x86: * Fixes for Xen emulation. * Add a global struct to consolidate tracking of host values, e.g. EFER * Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the effective APIC bus frequency, because TDX. * Print the name of the APICv/AVIC inhibits in the relevant tracepoint. * Clean up KVM's handling of vendor specific emulation to consistently act on "compatible with Intel/AMD", versus checking for a specific vendor. * Drop MTRR virtualization, and instead always honor guest PAT on CPUs that support self-snoop. * Update to the newfangled Intel CPU FMS infrastructure. * Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as it reads '0' and writes from userspace are ignored. * Misc cleanups x86 - MMU: * Small cleanups, renames and refactoring extracted from the upcoming Intel TDX support. * Don't allocate kvm_mmu_page.shadowed_translation for shadow pages that can't hold leafs SPTEs. * Unconditionally drop mmu_lock when allocating TDP MMU page tables for eager page splitting, to avoid stalling vCPUs when splitting huge pages. * Bug the VM instead of simply warning if KVM tries to split a SPTE that is non-present or not-huge. KVM is guaranteed to end up in a broken state because the callers fully expect a valid SPTE, it's all but dangerous to let more MMU changes happen afterwards. x86 - AMD: * Make per-CPU save_area allocations NUMA-aware. * Force sev_es_host_save_area() to be inlined to avoid calling into an instrumentable function from noinstr code. * Base support for running SEV-SNP guests. API-wise, this includes a new KVM_X86_SNP_VM type, encrypting/measure the initial image into guest memory, and finalizing it before launching it. Internally, there are some gmem/mmu hooks needed to prepare gmem-allocated pages before mapping them into guest private memory ranges. This includes basic support for attestation guest requests, enough to say that KVM supports the GHCB 2.0 specification. There is no support yet for loading into the firmware those signing keys to be used for attestation requests, and therefore no need yet for the host to provide certificate data for those keys. To support fetching certificate data from userspace, a new KVM exit type will be needed to handle fetching the certificate from userspace. An attempt to define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this was introduced in v1 of this patchset, but is still being discussed by community, so for now this patchset only implements a stub version of SNP Extended Guest Requests that does not provide certificate data. x86 - Intel: * Remove an unnecessary EPT TLB flush when enabling hardware. * Fix a series of bugs that cause KVM to fail to detect nested pending posted interrupts as valid wake eents for a vCPU executing HLT in L2 (with HLT-exiting disable by L1). * KVM: x86: Suppress MMIO that is triggered during task switch emulation Explicitly suppress userspace emulated MMIO exits that are triggered when emulating a task switch as KVM doesn't support userspace MMIO during complex (multi-step) emulation. Silently ignoring the exit request can result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace for some other reason prior to purging mmio_needed. See commit |

kbuild: Abort make on install failures
Setting '-e' flag tells shells to exit with error exit code immediately after any of commands fails, and causes make(1) to regard recipes as failed. Before this, make will still continue to succeed even after the installation failed, for example, for insufficient permission or directory does not exist.

arm64: qcom: don't select HAVE_PWRCTL when PCI=n
The new HAVE_PWRCTL option is defined in the PCI subsystem, so
selecting it unconditionally when PCI is disabled causes a harmless
warning:
WARNING: unmet direct dependencies detected for HAVE_PWRCTL
Depends on [n]: PCI [=n]
Selected by [y]:
- ARCH_QCOM [=y]
Add 'if PCI' in the qualcomm platform to hide the warning.

ftrace: Rewrite of function graph tracer
Up until now, the function graph tracer could only have a single user attached to it. If another user tried to attach to the function graph tracer while one was already attached, it would fail. Allowing function graph tracer to have more than one user has been asked for since 2009, but it required a rewrite to the logic to pull it off so it never happened. Until now! There's three systems that trace the return of a function. That is kretprobes, function graph tracer, and BPF. kretprobes and function graph tracing both do it similarly. The difference is that kretprobes uses a shadow stack per callback and function graph tracer creates a shadow stack for all tasks. The function graph tracer method makes it possible to trace the return of all functions. As kretprobes now needs that feature too, allowing it to use function graph tracer was needed. BPF also wants to trace the return of many probes and its method doesn't scale either. Having it use function graph tracer would improve that. By allowing function graph tracer to have multiple users allows both kretprobes and BPF to use function graph tracer in these cases. This will allow kretprobes code to be removed in the future as it's version will no longer be needed. Note, function graph tracer is only limited to 16 simultaneous users, due to shadow stack size and allocated slots. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZpbWlxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qgtvAP9jxmgEiEhz4Bpe1vRKVSMYK6ozXHTT 7MFKRMeQqQ8zeAEA2sD5Zrt9l7zKzg0DFpaDLgc3/yh14afIDxzTlIvkmQ8= =umuf -----END PGP SIGNATURE----- Merge tag 'ftrace-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: "Rewrite of function graph tracer to allow multiple users Up until now, the function graph tracer could only have a single user attached to it.

Kconfig: reduce the amount of power sequencing noise
Kconfig will ask the user twice about power sequencing: once for the QCom
WCN power sequencing driver and then again for the PCI power control
driver using it.
Let's automate the selection of PCI_PWRCTL by introducing a new hidden
symbol: HAVE_PWRCTL which should be selected by all platforms that have
the need to include PCI power control code (right now: only ARCH_QCOM).
The pwrseq-based PCI pwrctl driver itself will then be selected by the
drivers binding to devices that may require external handling of the
power-up sequence (currently: ath11k and ath12k) based on the value
of HAVE_PWRCTL.
Make all PCI pwrctl Kconfig symbols hidden so that no questions are
asked during configuration.

Networking changes for 6.11. Not much excitement - a handful of large
patchsets (devmem among them) did not make it in time.
Core & protocols
----------------
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT.
- Use flex array for netdevice priv area, ensure its cache alignment.
- Add a sysctl knob to allow user to specify a default rto_min at socket
init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful.
- Support scheduling transmission of packets based on CLOCK_TAI.
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
using cpusets.
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
- Allow configuration of multipath hash seed, to both allow synchronizing
hashing of two routers, and preventing partial accidental sync.
- Improve TCP compliance with RFC 9293 for simultaneous connect().
- Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
IKE daemon had to do this before, but the kernel can better keep
track of it.
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
- Introduce IPPROTO_SMC for selecting SMC when socket is created.
- Allow UDP GSO transmit from devices with no checksum offload.
- openvswitch: add packet sampling via psample, separating the sampled
traffic from "upcall" packets sent to user space for forwarding.
- nf_tables: shrink memory consumption for transaction objects.
Things we sprinkled into general kernel code
--------------------------------------------
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver
for QCA6390).
- Add IRQ information in sysfs for auxiliary bus.
- Introduce guard definition for local_lock.
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures.
BPF
---
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered.
- Add new kfuncs for a generic, open-coded bits iterator.
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head.
- Support resilient split BTF which cuts down on duplication and makes
BTF as compact as possible WRT BTF from modules.
- Add support for dumping kfunc prototypes from BTF which enables both
detecting as well as dumping compilable prototypes for kfuncs.
- riscv64 BPF JIT improvements in particular to add 12-argument support
for BPF trampolines and to utilize bpf_prog_pack for the latter.
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs.
Driver API
----------
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose.
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits.
- Track additional RSS contexts in the core, make sure configuration
changes don't break them.
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
data paths.
- Support updating firmware on SFP modules.
Tests and tooling
-----------------
- mptcp: use net/lib.sh to manage netns.
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints.
- openvswitch: make test self-contained (don't depend on OvS CLI tools).

Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.
Core & protocols:
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT
- Use flex array for netdevice priv area, ensure its cache alignment
- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful
- Support scheduling transmission of packets based on CLOCK_TAI
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync
- Improve TCP compliance with RFC 9293 for simultaneous connect()
- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
- Introduce IPPROTO_SMC for selecting SMC when socket is created
- Allow UDP GSO transmit from devices with no checksum offload
- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding
- nf_tables: shrink memory consumption for transaction objects
Things we sprinkled into general kernel code:
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]
- Add IRQ information in sysfs for auxiliary bus
- Introduce guard definition for local_lock
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures
BPF:
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered
- Add new kfuncs for a generic, open-coded bits iterator
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head
- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules
- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs
- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs
Driver API:
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits
- Track additional RSS contexts in the core, make sure configuration
changes don't break them
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths
- Support updating firmware on SFP modules
Tests and tooling:
- mptcp: use net/lib.sh to manage netns

tracepoints

asm-generic updates for 6.11
Most of this is part of my ongoing work to clean up the system call tables. In this bit, all of the newer architectures are converted to use the machine readable syscall.tbl format instead in place of complex macros in include/uapi/asm-generic/unistd.h. This follows an earlier series that fixed various API mismatches and in turn is used as the base for planned simplifications. The other two patches are dead code removal and a warning fix. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmaVB1cACgkQYKtH/8kJ UicMqxAAnYKOxfjoMIhYYK6bl126wg/vIcDcjIR9cNWH21Nhn3qxn11ZXau3S7xv 3l/HreEhyEQr4gC2a70IlXyHUadYOlrk+83OURrunWk1oKPmZlMKcfPVbtp8GL7x PUNXQfwM1XZLveKwufY24hoZdwKC+Y/5WLc1t0ReznJuAqgeO2rM9W5dnV5bAfCp he3F5hFcr196Dz3/GJjJIWrY+cbwfmZWsNtj1vFTL5/r/LuCu8HTkqhsGj8tE5BJ NGVEEXbp5eaVTCIGqJWhnuZcsnKN9kM51M7CtdwWf8OTckUVuJap5OsDVKQkWkGl bLPbd2jhDltph0sah51hAIvv4WdkThW76u9FRW7KR3fo7ra67eF7l5j7wc1lE2JB GwLJ1X56Bxe1GhvvNTlDmb7DrnlP/DMPuRv3Z6xyH6l8iZ2pMGlnAxuw6Bs1s6Y5 WSs36ZpnS0ctgjfx37ZITsZSvbKFPpQFJP4siwS8aRNv/NFALNNdFyOCY5lNzspZ 0dxwjn6/7UpHE4MKh6/hvCg2QwupXXBTRytibw+75/rOsR+EYlmtuONtyq2sLUHe ktJ5pg+8XuZm27+wLffuluzmY7sv2F8OU4cTYeM60Ynmc6pRzwUY6/VhG52S1/mU Ua4VgYIpzOtlLrYmz5QTWIZpdSFSVbIc/3pLriD6hn4Mvg+BwdA= =XOhL -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "Most of this is part of my ongoing work to clean up the system call tables.

soc: dt updates for 6.11
The devicetree updates are fairly well spread out across platforms,
with Qualcomm making up about a third of the total.
There are three new SoCs in existing product families this:
- NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores
instead of just two as well as a GPU and more high-speed I/O
devices.
- Qualcomm QCS8550 is a variant of SM8550 for IOT devices
- Airoha EN7581 is a 10G-PON network chip and related to
the MT7981 Wireless router chip from its parent Mediatek.
In total there are 58 new machines, including four riscv
boards and eight for 32-bit arm.
The most exciting new addition is probably a pair of laptops
based on the Qualcomm x1e80100 (Snapdragon X1 Elite) chip,
the Asus Vivobook S15 and the Lenovo Yoga Slim7x.
Other noteworthy new additions are:
- A total of 20 Qualcomm based machines, mostly Android devices
from Samsung, Motorola and LG, as well as a wireless router
and some reference designs
- Six NXP i.MX based machines, mostly industrial boards along
with some reference designs
- Mediatek sees some interesting Filogic based routers
including the "OpenWRT One", a few new Chromebooks as
well as single-board computers.
- Four machines from Solidrun based on Marvell cn913x,
replacing the older Armada 8000 based counterparts
- The four Amlogic machines are all set top boxes or reference
designs for them
- The nine new Rockchips machines are mostly single-board
computers including some interesting ones based on the
rk3588 chip like the ROCK 5 ITX board and the CM3588
with its four NVMe slots
- The RISC-V boards are all single-board computers based on
Starfive JH7110, Microchip MPFS and Allwinner D1, which all
had similar boards already
There are also a lot of updates to already supported machines,
notably for the TI K3, Rockchips, Freescale and of course
Qualcomm platforms.

soc: driver updates for 6.11
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are farily small maintenance changes, either addressing minor mistakes or enabling additional hardware. The qualcomm platform changes add a number of features and are larger than the other ones combined, introducing the use of linux/cleanup.h across several drivers, adding support for Snapdragon X1E and other SoCs in platform drivers, a new "protection domain mapper" driver, and a "shared memory bridge" driver. The cznic "turris omnia" router based on Marvell Armada gets a platform driver that talks to the board specific microcontroller. The reset and cache subsystems get a few minor updates to SoC specific drivers, while the ff-a, scmi and optee firmware drivers get some code refactoring and new features. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmaVTTUACgkQYKtH/8kJ UiegixAAqGfwUtwk2GGZJlEGjUjT4cqrwCTLhNlaNfgN/dZxjk1XBTKvtp2mVDi2 lJN8TNqa0Csw8XZYPgHi0s1ppmwQl07Unpbc9tUeS4tAeIuputDe+ia0UtQx3Mkd GTAKJO6VzLeCnDxB4757OURZO9wYlPdZycQbnSKDyfBIapFuZwozmbAc7BuFGvBv 2Zt5lca531EJuM5wg25f+F/8XSxZIqjMA6/PTGNCYig1bx5AM2tCWK2xN+BL+dxn YVLuRZT7lSgpwivg9OHzJ49g9WeJB7RArnSDg1Ac7sNfC8476UC17BAH4rF7QSTP q2GBP2VOdRJA9mJkavtLhE/1LPDJuYTM+nt1xq7jzG2MKN7yLjX0LMrMgKsk0pXZ T2qQh7+4MA9lwlpGEwDruMajTJahbMgiAUcSivLsr18LrifAnKVHBDTRmRwNiRX2 T3/zk90kenJX1NOkc4SrdLd5iCyq0oSN+fukdh3UMgJLnAzaWOe5mKAMF7eefeog rMH276W8JwbbmIC4R2aQm6TL7IWBtaCaHuLqYOiTjooir31OgwW4Mztd7okU4v4I rOGhV0zJTSVXT+a4O2jOooWppS9xE45/F2DSigSvZjEiahZ0L4feaOrHui5PVVlW wmFmobCq6Y0Mjspdk64O1tbUWJ17CmRK1WDrUUk0VgmLy9gn6A8= =ChcR -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are fairly small maintenance changes, either addressing minor mistakes or enabling additional hardware.

KVM generic changes for 6.11
- Enable halt poll shrinking by default, as Intel found it to be a clear win.
- Setup empty IRQ routing when creating a VM to avoid having to synchronize
SRCU when creating a split IRQCHIP on x86.
- Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag
that arch code can use for hooking both sched_in() and sched_out().
- Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
truncating a bogus value from userspace, e.g. to help userspace detect bugs.
- Mark a vCPU as preempted if and only if it's scheduled out while in the
KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest
memory when retrieving guest state during live migration blackout.

Merge branch 'arm64-uaccess' (early part)
Merge arm64 support for proper 'unsafe' user accessor functionality, with 'asm goto' for handling exceptions. The arm64 user access code used the slow fallback code for the user access code, which generates horrendous code for things like strncpy_from_user(), because it causes us to generate code for SW PAN and for range checking for every individual word. Teach arm64 about 'user_access_begin()' and the so-called 'unsafe' user access functions that take an error label and use 'asm goto' to make all the exception handling be entirely out of line. [ These user access functions are called 'unsafe' not because the concept is unsafe, but because the low-level accessor functions absolutely have to be protected by the 'user_access_begin()' code, because that's what does the range checking. So the accessor functions have that scary name to make sure people don't think they are usable on their own, and cannot be mis-used the way our old "double underscore" versions of __get_user() and friends were ] The "(early part)" of the branch is because the full branch also improved on the "access_ok()" function, but the exact semantics of TBI (top byte ignore) have to be discussed before doing that part. So this just does the low-level accessor update to use "asm goto". * 'arm64-uaccess' (early part): arm64: start using 'asm goto' for put_user() arm64: start using 'asm goto' for get_user() when available |

treewide: change conditional prompt for choices to 'depends on'
While Documentation/kbuild/kconfig-language.rst provides a brief
explanation, there are recurring confusions regarding the usage of a
prompt followed by 'if <expr>'. This conditional controls _only_ the
prompt.
A typical usage is as follows:
menuconfig BLOCK
bool "Enable the block layer" if EXPERT
default y
When EXPERT=n, the prompt is hidden, but this config entry is still
active, and BLOCK is set to its default value 'y'. This is reasonable
because you are likely want to enable the block device support. When
EXPERT=y, the prompt is shown, allowing you to toggle BLOCK.
Please note that it is different from 'depends on EXPERT', which would
enable and disable the entire config entry.
However, this conditional prompt has never worked in a choice block.
The following two work in the same way: when EXPERT is disabled, the
choice block is entirely disabled.
[Test Code 1]
choice
prompt "choose" if EXPERT
config A
bool "A"
config B
bool "B"
endchoice
[Test Code 2]
choice
prompt "choose"
depends on EXPERT
config A
bool "A"
config B
bool "B"
endchoice
I believe the first case should hide only the prompt, producing the
default:
CONFIG_A=y
# CONFIG_B is not set
The next commit will change (fix) the behavior of the conditional prompt
in choice blocks.
I see several choice blocks wrongly using a conditional prompt, where
'depends on' makes more sense.
To preserve the current behavior, this commit converts such misuses.
I did not touch the following entry in arch/x86/Kconfig:
choice
prompt "Memory split" if EXPERT
default VMSPLIT_3G
This is truly the correct use of the conditional prompt; when EXPERT=n,
this choice block should silently select the reasonable VMSPLIT_3G,
although the resulting PAGE_OFFSET will not be affected anyway.
Presumably, the one in fs/jffs2/Kconfig is also correct, but I converted
it to 'depends on' to avoid any potential behavioral change.

Merge branch 'word-at-a-time'
Merge minor word-at-a-time instruction choice improvements for x86 and arm64. This is the second of four branches that came out of me looking at the code generation for path lookup on arm64. The word-at-a-time infrastructure is used to do string operations in chunks of one word both when copying the pathname from user space (in strncpy_from_user()), and when parsing and hashing the individual path components (in link_path_walk()). In particular, the "find the first zero byte" uses various bit tricks to figure out the end of the string or path component, and get the length without having to do things one byte at a time. Both x86-64 and arm64 had less than optimal code choices for that. The commit message for the arm64 change in particular tries to explain the exact code flow for the zero byte finding for people who care. It's made a bit more complicated by the fact that we support big-endian hardware too, and so we have some extra abstraction layers to allow different models for finding the zero byte, quite apart from the issue of picking specialized instructions. * word-at-a-time: arm64: word-at-a-time: improve byte count calculations for LE x86-64: word-at-a-time: improve byte count calculations |

Merge branch 'runtime-constants'
Merge runtime constants infrastructure with implementations for x86 and
arm64.
This is one of four branches that came out of me looking at profiles of
my kernel build filesystem load on my 128-core Altra arm64 system, where
pathname walking and the user copies (particularly strncpy_from_user()
for fetching the pathname from user space) is very hot.
This is a very specialized "instruction alternatives" model where the
dentry hash pointer and hash count will be constants for the lifetime of
the kernel, but the allocation are not static but done early during the
kernel boot. In order to avoid the pointer load and dynamic shift, we
just rewrite the constants in the instructions in place.
We can't use the "generic" alternative instructions infrastructure,
because different architectures do it very differently, and it's
actually simpler to just have very specific helpers, with a fallback to
the generic ("old") model of just using variables for architectures that
do not implement the runtime constant patching infrastructure.

Merge branch kvm-arm64/shadow-mmu into kvmarm/next
* kvm-arm64/shadow-mmu:
: Shadow stage-2 MMU support for NV, courtesy of Marc Zyngier
:
: Initial implementation of shadow stage-2 page tables to support a guest
: hypervisor. In the author's words:
:
: So here's the 10000m (approximately 30000ft for those of you stuck
: with the wrong units) view of what this is doing:
:
: - for each {VMID,VTTBR,VTCR} tuple the guest uses, we use a
: separate shadow s2_mmu context. This context has its own "real"
: VMID and a set of page tables that are the combination of the
: guest's S2 and the host S2, built dynamically one fault at a time.
:
: - these shadow S2 contexts are ephemeral, and behave exactly as
: TLBs. For all intent and purposes, they *are* TLBs, and we discard
: them pretty often.
:
: - TLB invalidation takes three possible paths:
:
: * either this is an EL2 S1 invalidation, and we directly emulate
: it as early as possible
:
: * or this is an EL1 S1 invalidation, and we need to apply it to
: the shadow S2s (plural!) that match the VMID set by the L1 guest
:
: * or finally, this is affecting S2, and we need to teardown the
: corresponding part of the shadow S2s, which invalidates the TLBs
KVM: arm64: nv: Truely enable nXS TLBI operations
KVM: arm64: nv: Add handling of NXS-flavoured TLBI operations
KVM: arm64: nv: Add handling of range-based TLBI operations

mm: provide mm_struct and address to huge_ptep_get()
On powerpc 8xx huge_ptep_get() will need to know whether the given ptep is a PTE entry or a PMD entry. This cannot be known with the PMD entry itself because there is no easy way to know it from the content of the entry. So huge_ptep_get() will need to know either the size of the page or get the pmd. In order to be consistent with huge_ptep_get_and_clear(), give mm and address to huge_ptep_get().

bpf, arm64: Fix trampoline for BPF_TRAMP_F_CALL_ORIG
When BPF_TRAMP_F_CALL_ORIG is set, the trampoline calls
__bpf_tramp_enter() and __bpf_tramp_exit() functions, passing them
the struct bpf_tramp_image *im pointer as an argument in R0.
The trampoline generation code uses emit_addr_mov_i64() to emit
instructions for moving the bpf_tramp_image address into R0, but
emit_addr_mov_i64() assumes the address to be in the vmalloc() space
and uses only 48 bits. Because bpf_tramp_image is allocated using
kzalloc(), its address can use more than 48-bits, in this case the
trampoline will pass an invalid address to __bpf_tramp_enter/exit()
causing a kernel crash.
Fix this by using emit_a64_mov_i64() in place of emit_addr_mov_i64()
as it can work with addresses that are greater than 48-bits.
Fixes:
