      Pull tracing user-event updates from Steven Rostedt:
      
       - Minor update to the user_events interface
      
        The ABI of creating a user event states that the fields are separated
        by semicolons, and spaces should be ignored.
      
        But the parsing expected at least one space to be there (which was
        incorrect). Fix the reading of the string to handle fields separated
        by semicolons but no space between them.
      
        This does extend the API sightly as now "field;field" will now be
        parsed and not cause an error. But it should not cause any regressions
        as no logic should expect it to fail.
      
        Note, that the logic that parses the event fields to create the
        trace_event works with no spaces after the semi-colon. It is
        the logic that tests against existing events that is inconsistent.
        This causes registering an event without using spaces to succeed
        if it doesn't exist, but makes the same call that tries to register
        to the same event, but doesn't use spaces, fail.

      Pull tracing ring buffer updates from Steven Rostedt:
       "Add ring_buffer memory mappings.
      
        The tracing ring buffer was created based on being mostly used with
        the splice system call. It is broken up into page ordered sub-buffers
        and the reader swaps a new sub-buffer with an existing sub-buffer
        that's part of the write buffer. It then has total access to the
        swapped out sub-buffer and can do copyless movements of the memory
        into other mediums (file system, network, etc).
      
        The buffer is great for passing around the ring buffer contents in the
        kernel, but is not so good for when the consumer is the user space
        task itself.
      
        A new interface is added that allows user space to memory map the ring
        buffer. It will get all the write sub-buffers as well as reader
        sub-buffer (that is not written to). It can send an ioctl to change
        which sub-buffer is the new reader sub-buffer.
      
        The ring buffer is read only to user space. It only needs to call the
        ioctl when it is finished with a sub-buffer and needs a new sub-buffer
        that the writer will not write over.
      
        A self test program was also created for testing and can be used as an
        example for the interface to user space. The libtracefs (external to
        the kernel) also has code that interacts with this, although it is
        disabled until the interface is in a official release. It can be
        enabled by compiling the library with a special flag. This was used
        for testing applications that perform better with the buffer being
        mapped.
      
        Memory mapped buffers have limitations. The main one is that it can
        not be used with the snapshot logic. If the buffer is mapped,
        snapshots will be disabled. If any logic is set to trigger snapshots
        on a buffer, that buffer will not be allowed to be mapped"

       - Remove sentinel elements from ctl_table structs in kernel/*
      
         Removing sentinels in ctl_table arrays reduces the build time size
         and runtime memory consumed by ~64 bytes per array. Removals for
         net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
         through their respective subsystems making the next release the most
         likely place where the final series that removes the check for
         proc_name == NULL will land.
      
         This adds to removals already in arch/, drivers/ and fs/.
      
       - Adjust ctl_table definitions and references to allow constification
           - Remove unused ctl_table function arguments
           - Move non-const elements from ctl_table to ctl_table_header
           - Make ctl_table pointers const in ctl_table_root structure
      
         Making the static ctl_table structs const will increase safety by
         keeping the pointers to proc_handler functions in .rodata. Though no
         ctl_tables where made const in this PR, the ground work for making
         that possible has started with these changes sent by Thomas
         Weißschuh.

           changes with the missing properties as well as a binman compatible.
      
         - Krzysztof Kozlowski on his side shared a new yaml for describing
           Samsung's OneNAND interface.
      
         - The interface with NVMEM has also been slightly improved/fixed,
           especially now that OTP are also supported in the NAND subsystem.
      
         - Along with these changes, small cleanups have also been contributed
           around ID tables, structure sizes, arithmetic checks and comments.
      
        Raw NAND subsystem:
      
         - Two small fixes, one in the Hynix vendor code for properly
           returning an error which might have been ignored and another in the
           Davinci driver to properly synchronize the controller with the gpio
           domain.
      
        SPI NOR subsystem:
      
         - SPI NOR now uses div_u64() instead of div64_u64() in places where
           the divisor is 32 bits. Many 32 bit architectures can optimize this
           variant better than a full 64 bit divide"

      Arunpravin Paneer Selvam authored
      Problem statement: During the system boot time, an application request
      for the bulk volume of cleared range bias memory when the clear_avail
      is zero, we dont fallback into normal allocation method as we had an
      unnecessary clear_avail check which prevents the fallback method leads
      to fb allocation failure following system goes into unresponsive state.
      
      Solution: Remove the unnecessary clear_avail check in the range bias
      allocation function.

       - The locking around cpuset hotplug processing has always been a bit of
         mess which was worked around by making hotplug processing
         asynchronous. The asynchronity isn't great and led to other issues.
      
         We tried to make the behavior synchronous a while ago but that led to
         lockdep splats. Waiman took another stab at cleaning up and making it
         synchronous. The patch has been in -next for well over a month and
         there haven't been any complaints, so fingers crossed.
      
       - Tracepoints added to help understanding rstat lock contentions.

      kprobe/ftrace: bail out if ftrace was killed · 1a7d0890
      Stephen Brennan authored
      If an error happens in ftrace, ftrace_kill() will prevent disarming
      kprobes. Eventually, the ftrace_ops associated with the kprobes will be
      freed, yet the kprobes will still be active, and when triggered, they
      will use the freed memory, likely resulting in a page fault and panic.
      
      This behavior can be reproduced quite easily, by creating a kprobe and
      then triggering a ftrace_kill(). For simplicity, we can simulate an
      ftrace error with a kernel module like [1]:
      
      [1]: https://github.com/brenns10/kernel_stuff/tree/master/ftrace_killer
      
        sudo perf probe --add commit_creds
        sudo perf trace -e probe:commit_creds
        # In another terminal
        make
        sudo insmod ftrace_killer.ko  # calls ftrace_kill(), simulating bug
        # Back to perf terminal
        # ctrl-c
        sudo perf probe --del commit_creds
      
      After a short period, a page fault and panic would occur as the kprobe
      continues to execute and uses the freed ftrace_ops. While ftrace_kill()
      is supposed to be used only in extreme circumstances, it is invoked in
      FTRACE_WARN_ON() and so there are many places where an unexpected bug
      could be triggered, yet the system may continue operating, possibly
      without the administrator noticing. If ftrace_kill() does not panic the
      system, then we should do everything we can to continue operating,
      rather than leave a ticking time bomb.

      Pull KVM updates from Paolo Bonzini:
       "ARM:
      
         - Move a lot of state that was previously stored on a per vcpu basis
           into a per-CPU area, because it is only pertinent to the host while
           the vcpu is loaded. This results in better state tracking, and a
           smaller vcpu structure.
      
         - Add full handling of the ERET/ERETAA/ERETAB instructions in nested
           virtualisation. The last two instructions also require emulating
           part of the pointer authentication extension. As a result, the trap
           handling of pointer authentication has been greatly simplified.
      
         - Turn the global (and not very scalable) LPI translation cache into
           a per-ITS, scalable cache, making non directly injected LPIs much
           cheaper to make visible to the vcpu.
      
         - A batch of pKVM patches, mostly fixes and cleanups, as the
           upstreaming process seems to be resuming. Fingers crossed!
      
         - Allocate PPIs and SGIs outside of the vcpu structure, allowing for
           smaller EL2 mapping and some flexibility in implementing more or
           less than 32 private IRQs.
      
         - Purge stale mpidr_data if a vcpu is created after the MPIDR map has
           been created.
      
         - Preserve vcpu-specific ID registers across a vcpu reset.
      
         - Various minor cleanups and improvements.
      
        LoongArch:
      
         - Add ParaVirt IPI support
      
         - Add software breakpoint support
      
         - Add mmio trace events support
      
        RISC-V:
      
         - Support guest breakpoints using ebreak
      
         - Introduce per-VCPU mp_state_lock and reset_cntx_lock
      
         - Virtualize SBI PMU snapshot and counter overflow interrupts
      
         - New selftests for SBI PMU and Guest ebreak
      
         - Some preparatory work for both TDX and SNP page fault handling.
      
           This also cleans up the page fault path, so that the priorities of
           various kinds of fauls (private page, no memory, write to read-only
           slot, etc.) are easier to follow.
      
        x86:
      
         - Minimize amount of time that shadow PTEs remain in the special
           REMOVED_SPTE state.
      
           This is a state where the mmu_lock is held for reading but
           concurrent accesses to the PTE have to spin; shortening its use
           allows other vCPUs to repopulate the zapped region while the zapper
           finishes tearing down the old, defunct page tables.
      
         - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID
           field, which is defined by hardware but left for software use.
      
           This lets KVM communicate its inability to map GPAs that set bits
           51:48 on hosts without 5-level nested page tables. Guest firmware
           is expected to use the information when mapping BARs; this avoids
           that they end up at a legal, but unmappable, GPA.
      
         - Fixed a bug where KVM would not reject accesses to MSR that aren't
           supposed to exist given the vCPU model and/or KVM configuration.
      
         - As usual, a bunch of code cleanups.
      
        x86 (AMD):
      
         - Implement a new and improved API to initialize SEV and SEV-ES VMs,
           which will also be extendable to SEV-SNP.
      
           The new API specifies the desired encryption in KVM_CREATE_VM and
           then separately initializes the VM. The new API also allows
           customizing the desired set of VMSA features; the features affect
           the measurement of the VM's initial state, and therefore enabling
           them cannot be done tout court by the hypervisor.
      
           While at it, the new API includes two bugfixes that couldn't be
           applied to the old one without a flag day in userspace or without
           affecting the initial measurement. When a SEV-ES VM is created with
           the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected
           once the VMSA has been encrypted. Also, the FPU and AVX state will
           be synchronized and encrypted too.
      
         - Support for GHCB version 2 as applicable to SEV-ES guests.
      
           This, once more, is only accessible when using the new
           KVM_SEV_INIT2 flow for initialization of SEV-ES VMs.
      
        x86 (Intel):
      
         - An initial bunch of prerequisite patches for Intel TDX were merged.
      
           They generally don't do anything interesting. The only somewhat
           user visible change is a new debugging mode that checks that KVM's
           MMU never triggers a #VE virtualization exception in the guest.
      
         - Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig
           VM-Exit to L1, as per the SDM.
      
        Generic:
      
         - Use vfree() instead of kvfree() for allocations that always use
           vcalloc() or __vcalloc().
      
         - Remove .change_pte() MMU notifier - the changes to non-KVM code are
           small and Andrew Morton asked that I also take those through the
           KVM tree.
      
           The callback was only ever implemented by KVM (which was also the
           original user of MMU notifiers) but it had been nonfunctional ever
           since calls to set_pte_at_notify were wrapped with
           invalidate_range_start and invalidate_range_end... in 2012.
      
        Selftests:
      
         - Enhance the demand paging test to allow for better reporting and
           stressing of UFFD performance.
      
         - Convert the steal time test to generate TAP-friendly output.
      
         - Fix a flaky false positive in the xen_shinfo_test due to comparing
           elapsed time across two different clock domains.
      
         - Skip the MONITOR/MWAIT test if the host doesn't actually support
           MWAIT.
      
         - Avoid unnecessary use of "sudo" in the NX hugepage test wrapper
           shell script, to play nice with running in a minimal userspace
           environment.
      
         - Allow skipping the RSEQ test's sanity check that the vCPU was able
           to complete a reasonable number of KVM_RUNs, as the assert can fail
           on a completely valid setup.
      
           If the test is run on a large-ish system that is otherwise idle,
           and the test isn't affined to a low-ish number of CPUs, the vCPU
           task can be repeatedly migrated to CPUs that are in deep sleep
           states, which results in the vCPU having very little net runtime
           before the next migration due to high wakeup latencies.
      
         - Define _GNU_SOURCE for all selftests to fix a warning that was
           introduced by a change to kselftest_harness.h late in the 6.9
           cycle, and because forcing every test to #define _GNU_SOURCE is
           painful.
      
         - Provide a global pseudo-RNG instance for all tests, so that library
           code can generate random, but determinstic numbers.
      
         - Use the global pRNG to randomly force emulation of select writes
           from guest code on x86, e.g. to help validate KVM's emulation of
           locked accesses.
      
         - Allocate and initialize x86's GDT, IDT, TSS, segments, and default
           exception handlers at VM creation, instead of forcing tests to
           manually trigger the related setup.

       - Three CXL mailbox passthrough commands are added to support the

           - Get Supported Log Sub-List Commands
           - Clear Log
      
       - Add support of Device Phyiscal Address (DPA) to Host Physical Address
         (HPA) translation for CXL events of cxl_dram and cxl_general media.
      
         This allows user space to figure out which CXL region the event
         occured via trace event.
      
       - Connect CXL to CPER reporting.
      
         If a device is configured for firmware first, CXL event records are
         not sent directly to the host. Those records are reported through EFI
         Common Platform Error Records (CPER). Add support to route the CPER
         records through the CXL sub-system in order to provide DPA to HPA
         translation and also event decoding and tracing. This is useful for
         users to determine which system issues may correspond to specific
         hardware events.

      ARM: 9398/1: Fix userspace enter on LPAE with CC_OPTIMIZE_FOR_SIZE=y · eebadafc
      Geert Uytterhoeven authored
      Booting an LPAE-enabled kernel built with CONFIG_CC_OPTIMIZE_FOR_SIZE=y
      fails when starting userspace:
      
          Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004

      Add the missing memory clobber to cpu_set_ttbcr(), as suggested by
      Russell King.
      
      Force inlining of uaccess_save_and_enable(), as suggested by Ard
      Biesheuvel.
      
      The latter fixes booting on Koelsch.

       "This one became bigger than usual, not in the total size but rather
        containing lots of small changes all over the places.
      
        The majority of changes are about ASoC, especially SOF / Intel stuff,
        and we see an interesting work for ASoC DAPM graph visualization,
        while there are many other code cleanup and refactoring, too.
      
        Core:
         - A deadlock fix at device disconnection
         - A new tool dapm-graph for visualising the DAPM state
      
        ASoC:
         - Large updates throughout the Intel audio drivers
         - Fixes and clarifications for the DAPM documentation
         - Cleanups of accessors for driver data, module labelling, and for
           constification
         - Modernsation and cleanup work in the Mediatek drivers
         - Several fixes and features for the DaVinci I2S driver
         - New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
           Rockchip RK3308 and Texas Instruments PCM6240
      
        HD-audio:
         - Cleanup for CONFIG_PM dependencies
         - Cirrus HD-audio codec fixes and quirks
      
        Others:
         - Series of tree-wide fixes in Makefiles to use *-y
         - Additions of missing module descriptions
         - Scarlett2 USB mixer enhancements
