bd6c11bc43 Networking changes for 6.6. 
Core
 ----
 
  - Increase size limits for to-be-sent skb frag allocations. This
    allows tun, tap devices and packet sockets to better cope with large
    writes operations.
 
  - Store netdevs in an xarray, to simplify iterating over netdevs.
 
  - Refactor nexthop selection for multipath routes.
 
  - Improve sched class lifetime handling.
 
  - Add backup nexthop ID support for bridge.
 
  - Implement drop reasons support in openvswitch.
 
  - Several data races annotations and fixes.
 
  - Constify the sk parameter of routing functions.
 
  - Prepend kernel version to netconsole message.
 
 Protocols
 ---------
 
  - Implement support for TCP probing the peer being under memory
    pressure.
 
  - Remove hard coded limitation on IPv6 specific info placement
    inside the socket struct.
 
  - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
    per socket scaling factor.
 
  - Scaling-up the IPv6 expired route GC via a separated list of
    expiring routes.
 
  - In-kernel support for the TLS alert protocol.
 
  - Better support for UDP reuseport with connected sockets.
 
  - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
    header size.
 
  - Get rid of additional ancillary per MPTCP connection struct socket.
 
  - Implement support for BPF-based MPTCP packet schedulers.
 
  - Format MPTCP subtests selftests results in TAP.
 
  - Several new SMC 2.1 features including unique experimental options,
    max connections per lgr negotiation, max links per lgr negotiation.
 
 BPF
 ---
 
  - Multi-buffer support in AF_XDP.
 
  - Add multi uprobe BPF links for attaching multiple uprobes
    and usdt probes, which is significantly faster and saves extra fds.
 
  - Implement an fd-based tc BPF attach API (TCX) and BPF link support on
    top of it.
 
  - Add SO_REUSEPORT support for TC bpf_sk_assign.
 
  - Support new instructions from cpu v4 to simplify the generated code and
    feature completeness, for x86, arm64, riscv64.
 
  - Support defragmenting IPv(4|6) packets in BPF.
 
  - Teach verifier actual bounds of bpf_get_smp_processor_id()
    and fix perf+libbpf issue related to custom section handling.
 
  - Introduce bpf map element count and enable it for all program types.
 
  - Add a BPF hook in sys_socket() to change the protocol ID
    from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
 
  - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
 
  - Add uprobe support for the bpf_get_func_ip helper.
 
  - Check skb ownership against full socket.
 
  - Support for up to 12 arguments in BPF trampoline.
 
  - Extend link_info for kprobe_multi and perf_event links.
 
 Netfilter
 ---------
 
  - Speed-up process exit by aborting ruleset validation if a
    fatal signal is pending.
 
  - Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
 
 Driver API
 ----------
 
  - Page pool optimizations, to improve data locality and cache usage.
 
  - Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
    for raw ioctl() handling in drivers.
 
  - Simplify genetlink dump operations (doit/dumpit) providing them
    the common information already populated in struct genl_info.
 
  - Extend and use the yaml devlink specs to [re]generate the split ops.
 
  - Introduce devlink selective dumps, to allow SF filtering SF based on
    handle and other attributes.
 
  - Add yaml netlink spec for netlink-raw families, allow route, link and
    address related queries via the ynl tool.
 
  - Remove phylink legacy mode support.
 
  - Support offload LED blinking to phy.
 
  - Add devlink port function attributes for IPsec.

Pull gpio updates from Bartosz Golaszewski:
 "We have a lot of code refactoring using common helpers and ended up
  removing more lines then we're adding this release cycle.

  Nothing really stands out, just small updates all over the place.

  Core GPIOLIB updates:
   - wake-up poll() in user-space on device unbind
   - improve fwnode usage
   - interrupt domain handling improvements
   - correctly handle the ngpios property in gpio-mmio

  Driver cleanups:
   - remove unneeded calls to platform_set_drvdata() all around the
     place
   - remove unneeded of_match_ptr() expansions whenever a driver depends
     on CONFIG_OF
   - remove redundant calls to dev_err_probe() from gpio-omap and
     gpio-davinci

  Driver improvements:
   - use autopointers and guards from cleanup.h in gpio-sim
   - shrink code in gpio-sim using some common helpers
   - convert the idio family of drivers to using gpio-regmap
   - convert gpio-ws16c48 to using gpio-regmap
   - use devres to simplify code in gpio-pisosr and gpio-mxc
   - update gpio-sifive: support IRQ wake, improve interrupt handling,
     allow building as module
   - make gpio-ge and gpio-bcm-kona OF-independent (plus some minor
     tweaks)
   - add support for new models in gpio-pca953x and gpio-ds4520
   - add runtime PM support to gpio-mxc
   - fix a build warning in gpio-mxs
   - add support for adding pin ranges to gpio-mlxbf3
   - add counter/timer support to gpio-104-dio-48e
   - switch to dynamic GPIO base allocation in gpio-vf610
   - minor oneliners here and there

  Device-tree bindings updates:
   - enable the gpio-line-names property in snps,dw-apb and STMPE GPIO
   - document new models in fsl-imx-gpio, ds4520 and pca95xx
   - convert the bindings for brcm,kona-gpio to YAML"

  - QuadSPI SPI support for Allwinner sun6i.

a031fe8d1d Rust changes for v6.6 
In terms of lines, most changes this time are on the pinned-init API
 and infrastructure. While we have a Rust version upgrade, and thus a
 bunch of changes from the vendored 'alloc' crate as usual, this time
 those do not account for many lines.
 
 Toolchain and infrastructure:
 
  - Upgrade to Rust 1.71.1. This is the second such upgrade, which is a
    smaller jump compared to the last time.
 
    This version allows us to remove the '__rust_*' allocator functions
    -- the compiler now generates them as expected, thus now our
    'KernelAllocator' is used.
 
    It also introduces the 'offset_of!' macro in the standard library
    (as an unstable feature) which we will need soon. So far, we were
    using a declarative macro as a prerequisite in some not-yet-landed
    patch series, which did not support sub-fields (i.e. nested structs):
 
        #[repr(C)]
        struct S {
            a: u16,
            b: (u8, u8),
        }
 
        assert_eq!(offset_of!(S, b.1), 3);
 
  - Upgrade to bindgen 0.65.1. This is the first time we upgrade its
    version.
 
    Given it is a fairly big jump, it comes with a fair number of
    improvements/changes that affect us, such as a fix needed to support
    LLVM 16 as well as proper support for '__noreturn' C functions, which
    are now mapped to return the '!' type in Rust:
 
        void __noreturn f(void); // C
        pub fn f() -> !;         // Rust
 
  - 'scripts/rust_is_available.sh' improvements and fixes.
 
    This series takes care of all the issues known so far and adds a few
    new checks to cover for even more cases, plus adds some more help
    texts. All this together will hopefully make problematic setups
    easier to identify and to be solved by users building the kernel.
 
    In addition, it adds a test suite which covers all branches of the
    shell script, as well as tests for the issues found so far.
 
  - Support rust-analyzer for out-of-tree modules too.
 
  - Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.
 
  - Drop 'scripts/is_rust_module.sh' since it is not needed anymore.
 
 Macros crate:
 
  - New 'paste!' proc macro.
 
    This macro is a more flexible version of 'concat_idents!': it allows
    the resulting identifier to be used to declare new items and it
    allows to transform the identifiers before concatenating them, e.g.
 
        let x_1 = 42;
        paste!(let [<x _2>] = [<x _1>];);
        assert!(x_1 == x_2);
 
    The macro is then used for several of the pinned-init API changes in
    this pull.
 
 Pinned-init API:
 
  - Make '#[pin_data]' compatible with conditional compilation of fields,
    allowing to write code like:
 
        #[pin_data]
        pub struct Foo {
            #[cfg(CONFIG_BAR)]
            a: Bar,
            #[cfg(not(CONFIG_BAR))]
            a: Baz,
        }
 
  - New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait, which
    allows 'unsafe' implementations for structs where every field
    implements the 'Zeroable' trait, e.g.:
 
        #[derive(Zeroable)]
        pub struct DriverData {
            id: i64,
            buf_ptr: *mut u8,
            len: usize,
        }
 
  - Add '..Zeroable::zeroed()' syntax to the 'pin_init!'  macro for
    zeroing all other fields, e.g.:
 
        pin_init!(Buf {
            buf: [1; 64],
            ..Zeroable::zeroed()
        });
 
  - New '{,pin_}init_array_from_fn()' functions to create array
    initializers given a generator function, e.g.:
 
        let b: Box<[usize; 1_000]> = Box::init::<Error>(
            init_array_from_fn(|i| i)
        ).unwrap();
 
        assert_eq!(b.len(), 1_000);
        assert_eq!(b[123], 123);
 
  - New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
    execute a closure on the value directly after initialization, e.g.:
 
        let foo = init!(Foo {
            buf <- init::zeroed()
        }).chain(|foo| {
            foo.setup();
            Ok(())
        });
 
  - Support arbitrary paths in init macros, instead of just identifiers
    and generic types.
 
  - Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
    'Opaque<T>' types.
 
  - Make initializer values inaccessible after initialization.
 
  - Make guards in the init macros hygienic.
 
 'allocator' module:
 
  - Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
    misaligned allocations when the Rust 1.71.1 upgrade is applied later
    in this pull.
 
    The equivalent fix for the previous compiler version (where
    'KernelAllocator' is not yet used) was merged into 6.5 already,
    which added the 'krealloc_aligned()' function used here.
 
  - Implement 'KernelAllocator::{realloc, alloc_zeroed}' for performance,
    using 'krealloc_aligned()' too, which forwards the call to the C API.
 
 'types' module:
 
  - Make 'Opaque' be '!Unpin', removing the need to add a 'PhantomPinned'
    field to Rust structs that contain C structs which must not be moved.
 
  - Make 'Opaque' use 'UnsafeCell' as the outer type, rather than inner.
 
 Documentation:
 
  - Suggest obtaining the source code of the Rust's 'core' library using
    the tarball instead of the repository.

    as reviewers of the "RUST" entry.
 
 As well as a few other minor changes and cleanups.

1c59d38339 linux-kselftest-nolibc-6.6-rc1 
This nolibc update for Linux 6.6-rc1 consists of:
 
 Nolibc:
   - improved portability by removing build errors with -ENOSYS
   - added syscall6() on MIPS to support pselect6() and mmap()
   - added setvbuf(), rmdir(), pipe(), pipe2()
   - add support for ppc/ppc64
   - environ is no longer optional
   - fixed frame pointer issues at -O0
   - dropped sys_stat() in favor of sys_statx()
   - centralized _start_c() to remove lots of asm code
   - switched size_t to __SIZE_TYPE__
 
 Selftests:
   - improved status reporting (success/warning/failure counts,
     path to log file)
   - various code cleanups (indent, unused variables, ...)
   - more consistent test numbering
   - enabled compiler warnings
   - dropped unreliable chmod_net test
   - improved reliability (create /dev/zero & /tmp, rely less on /proc)
   - new tests (brk/sbrk/mmap/munmap)
   - improved compatibility with musl
   - new run-nolibc-test target to build and run natively
   - new run-libc-test target to build and run against native libc

 "These rework the Intel DTS IOSF and the ACPI thermal drivers to pass
  tables of generic trip point structures to the core during
  initialization and make some requisite modifications in the thermal
  core, fix a few issues elsewhere and clean up code.

  This includes changes that are present in the ACPI updates too,
  because they involve both ACPI and the thermal core. The list of
  specific changes below is limited to thermal control, however.

  Specifics:

     structures on top of the internal representation of trip points and

e5b7ca09e9 s390 updates for 6.6 merge window 
- Add vfio-ap support to pass-through crypto devices to secure execution
   guests
 
 - Add API ordinal 6 support to zcrypt_ep11misc device drive, which is
   required to handle key generate and key derive (e.g. secure key to
   protected key) correctly
 
 - Add missing secure/has_secure sysfs files for the case where it is not
   possible to figure where a system has been booted from. Existing user
   space relies on that these files are always present
 
 - Fix DCSS block device driver list corruption, caused by incorrect
   error handling
 
 - Convert virt_to_pfn() and pfn_to_virt() from defines to static inline
   functions to enforce type checking
 
 - Cleanups, improvements, and minor fixes to the kernel mapping setup
 
 - Fix various virtual vs physical address confusions
 
 - Move pfault code to separate file, since it has nothing to do with
   regular fault handling
 
 - Move s390 documentation to Documentation/arch/ like it has been done
   for other architectures already
 
 - Add HAVE_FUNCTION_GRAPH_RETVAL support
 
 - Factor out the s390_hypfs filesystem and add a new config option for
   it. The filesystem is deprecated and as soon as all users are gone it
   can be removed some time in the not so near future
 
 - Remove support for old CEX2 and CEX3 crypto cards from zcrypt device
   driver
 
 - Add support for user-defined certificates: receive user-defined
   certificates with a diagnose call and provide them via 'cert_store'
   keyring to user space
 
 - Couple of other small fixes and improvements all over the place

3ca9a836ff Scheduler changes for v6.6: 
- The biggest change is introduction of a new iteration of the
   SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual
   Deadline First") scheduler.
 
   EEVDF too is a virtual-time scheduler, with two parameters (weight
   and relative deadline), compared to CFS that had weight only.
   It completely reworks the base scheduler: placement, preemption,
   picking -- everything.
 
   LWN.net, as usual, has a terrific writeup about EEVDF:
 
      https://lwn.net/Articles/925371/
 
   Preemption (both tick and wakeup) is driven by testing against
   a fresh pick. Because the tree is now effectively an interval
   tree, and the selection is no longer the 'leftmost' task,
   over-scheduling is less of a problem. A lot of the CFS
   heuristics are removed or replaced by more natural latency-space
   parameters & constructs.
 
   In terms of expected performance regressions: we'll and can fix
   everything where a 'good' workload misbehaves with the new scheduler,
   but EEVDF inevitably changes workload scheduling in a binary fashion,
   hopefully for the better in the overwhelming majority of cases,
   but in some cases it won't, especially in adversarial loads that
   got lucky with the previous code, such as some variants of hackbench.
   We are trying hard to err on the side of fixing all performance
   regressions, but we expect some inevitable post-release iterations
   of that process.
 
 - Improve load-balancing on hybrid x86 systems: enable cluster
   scheduling (again).
 
 - Improve & fix bandwidth-scheduling on nohz systems.
 
 - Improve bandwidth-throttling.
 
 - Use lock guards to simplify and de-goto-ify control flow.
 
 - Misc improvements, cleanups and fixes.

bd9e99f790 - Avoid the baremetal decompressor code when booting on an EFI machine. 
This is mandated by the current tightening of EFI executables
   requirements when used in a secure boot scenario. More specifically,
   an EFI executable cannot have a single section with RWX permissions,

6f49693a6c Updates for the CPU hotplug core: 
- Support partial SMT enablement.
 
     So far the sysfs SMT control only allows to toggle between SMT on and
     off. That's sufficient for x86 which usually has at max two threads
     except for the Xeon PHI platform which has four threads per core.
 
     Though PowerPC has up to 16 threads per core and so far it's only
     possible to control the number of enabled threads per core via a
     command line option. There is some way to control this at runtime, but
     that lacks enforcement and the usability is awkward.
 
     This update expands the sysfs interface and the core infrastructure to
     accept numerical values so PowerPC can build SMT runtime control for
     partial SMT enablement on top.
 
     The core support has also been provided to the PowerPC maintainers who
     added the PowerPC related changes on top.
 
   - Minor cleanups and documentation updates.
