Pull CRC updates from Eric Biggers:
 "Another set of improvements to the kernel's CRC (cyclic redundancy
  check) code:

   - Rework the CRC64 library functions to be directly optimized, like
     what I did last cycle for the CRC32 and CRC-T10DIF library
     functions

   - Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ
     support and acceleration for crc64_be and crc64_nvme

   - Rewrite the riscv Zbc-optimized CRC code, and add acceleration for
     crc_t10dif, crc64_be, and crc64_nvme

   - Remove crc_t10dif and crc64_rocksoft from the crypto API, since
     they are no longer needed there

   - Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect

   - Add kunit test cases for crc64_nvme and crc7

   - Eliminate redundant functions for calculating the Castagnoli CRC32,
     settling on just crc32c()

   - Remove unnecessary prompts from some of the CRC kconfig options

   - Further optimize the x86 crc32c code"

Pull selinux updates from Paul Moore:

 - Add additional SELinux access controls for kernel file reads/loads

   The SELinux kernel file read/load access controls were never updated
   beyond the initial kernel module support, this pull request adds
   support for firmware, kexec, policies, and x.509 certificates.

 - Add support for wildcards in network interface names

   There are a number of userspace tools which auto-generate network
   interface names using some pattern of <XXXX>-<NN> where <XXXX> is a
   fixed string, e.g. "podman", and <NN> is a increasing counter.
   Supporting wildcards in the SELinux policy for network interfaces
   simplifies the policy associted with these interfaces.

 - Fix a potential problem in the kernel read file SELinux code

   SELinux should always check the file label in the
   security_kernel_read_file() LSM hook, regardless of if the file is
   being read in chunks. Unfortunately, the existing code only
   considered the file label on the first chunk; this pull request fixes
   this problem.

   There is more detail in the individual commit, but thankfully the
   existing code didn't expose a bug due to multi-stage reads only
   taking place in one driver, and that driver loading a file type that
   isn't targeted by the SELinux policy.

 - Fix the subshell error handling in the example policy loader

   Minor fix to SELinux example policy loader in scripts/selinux due to
   an undesired interaction with subshells and errexit.

Pull lsm updates from Paul Moore:

 - Various minor updates to the LSM Rust bindings

   Changes include marking trivial Rust bindings as inlines and comment
   tweaks to better reflect the LSM hooks.

 - Add LSM/SELinux access controls to io_uring_allowed()

   Similar to the io_uring_disabled sysctl, add a LSM hook to
   io_uring_allowed() to enable LSMs a simple way to enforce security
   policy on the use of io_uring. This pull request includes SELinux
   support for this new control using the io_uring/allowed permission.

 - Remove an unused parameter from the security_perf_event_open() hook

   The perf_event_attr struct parameter was not used by any currently
   supported LSMs, remove it from the hook.

 - Add an explicit MAINTAINERS entry for the credentials code

   We've seen problems in the past where patches to the credentials code
   sent by non-maintainers would often languish on the lists for
   multiple months as there was no one explicitly tasked with the
   responsibility of reviewing and/or merging credentials related code.

   Considering that most of the code under security/ has a vested
   interest in ensuring that the credentials code is well maintained,
   I'm volunteering to look after the credentials code and Serge Hallyn
   has also volunteered to step up as an official reviewer. I posted the
   MAINTAINERS update as a RFC to LKML in hopes that someone else would
   jump up with an "I'll do it!", but beyond Serge it was all crickets.

 "These include one thermal core fix for an issue leading to a NULL
  pointer dereference, a similar fix for the int340x thermal driver
  (even though the issue may not actually occur in practice in this

  kzalloc() with kcalloc() where applicable.

  Summary:

   - Delay exposing thermal zone sysfs interface to prevent user space
     from accessing thermal zones that have not been completely
     initialized yet (Lucas De Marchi)

   - Check a pointer against NULL early in int3402_thermal_probe() to

Pull power management updates from Rafael Wysocki:
 "These are dominated by cpufreq updates which in turn are dominated by
  updates related to boost support in the core and drivers and
  amd-pstate driver optimizations.

  Apart from the above, there are some cpuidle updates including a
  rework of the most recent idle intervals handling in the venerable
  menu governor that leads to significant improvements in some
  performance benchmarks, as the governor is now more likely to predict
  a shorter idle duration in some cases, and there are updates of the
  core device power management code, mostly related to system suspend
  and resume, that should help to avoid potential issues arising when
  the drivers of devices depending on one another want to use different
  optimizations.

  There is also a usual collection of assorted fixes and cleanups,
  including removal of some unused code.

  Specifics:

   - Manage sysfs attributes and boost frequencies efficiently from
     cpufreq core to reduce boilerplate code in drivers (Viresh Kumar)

   - Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
     Dhananjay Ugwekar, Imran Shaik, zuoqian)

   - Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
     Bai)

   - cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski)

   - Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng)

   - Optimize the amd-pstate driver to avoid cases where call paths end
     up calling the same writes multiple times and needlessly caching
     variables through code reorganization, locking overhaul and tracing
     adjustments (Mario Limonciello, Dhananjay Ugwekar)

   - Make it possible to avoid enabling capacity-aware scheduling (CAS)
     in the intel_pstate driver and relocate a check for out-of-band
     (OOB) platform handling in it to make it detect OOB before checking
     HWP availability (Rafael Wysocki)

   - Fix dbs_update() to avoid inadvertent conversions of negative
     integer values to unsigned int which causes CPU frequency selection
     to be inaccurate in some cases when the "conservative" cpufreq
     governor is in use (Jie Zhan)

   - Update the handling of the most recent idle intervals in the menu
     cpuidle governor to prevent useful information from being discarded
     by it in some cases and improve the prediction accuracy (Rafael
     Wysocki)

   - Make it possible to tell the intel_idle driver to ignore its
     built-in table of idle states for the given processor, clean up the
     handling of auto-demotion disabling on Baytrail and Cherrytrail
     chips in it, and update its MAINTAINERS entry (David Arcari, Artem
     Bityutskiy, Rafael Wysocki)

   - Make some cpuidle drivers use for_each_present_cpu() instead of
     for_each_possible_cpu() during initialization to avoid issues
     occurring when nosmp or maxcpus=0 are used (Jacky Bai)

   - Clean up the Energy Model handling code somewhat (Rafael Wysocki)

   - Use kfree_rcu() to simplify the handling of runtime Energy Model
     updates (Li RongQing)

   - Add an entry for the Energy Model framework to MAINTAINERS as
     properly maintained (Lukasz Luba)

   - Address RCU-related sparse warnings in the Energy Model code
     (Rafael Wysocki)

   - Remove ENERGY_MODEL dependency on SMP and allow it to be selected
     when DEVFREQ is set without CPUFREQ so it can be used on a wider
     range of systems (Jeson Gao)

   - Unify error handling during runtime suspend and runtime resume in
     the core to help drivers to implement more consistent runtime PM
     error handling (Rafael Wysocki)

   - Drop a redundant check from pm_runtime_force_resume() and rearrange
     documentation related to __pm_runtime_disable() (Rafael Wysocki)

   - Rework the handling of the "smart suspend" driver flag in the PM
     core to avoid issues hat may occur when drivers using it depend on
     some other drivers and clean up the related PM core code (Rafael
     Wysocki, Colin Ian King)

   - Fix the handling of devices with the power.direct_complete flag set
     if device_suspend() returns an error for at least one device to
     avoid situations in which some of them may not be resumed (Rafael
     Wysocki)

   - Use mutex_trylock() in hibernate_compressor_param_set() to avoid a
     possible deadlock that may occur if the "compressor" hibernation
     module parameter is accessed during the registration of a new
     ieee80211 device (Lizhi Xu)

   - Suppress sleeping parent warning in device_pm_add() in the case
     when new children are added under a device with the
     power.direct_complete set after it has been processed by
     device_resume() (Xu Yang)

   - Remove needless return in three void functions related to system
     wakeup (Zijun Hu)

   - Replace deprecated kmap_atomic() with kmap_local_page() in the
     hibernation core code (David Reaver)

   - Remove unused helper functions related to system sleep (David Alan
     Gilbert)

   - Clean up s2idle_enter() so it does not lock and unlock CPU offline
     in vain and update comments in it (Ulf Hansson)

   - Clean up broken white space in dpm_wait_for_children() (Geert
     Uytterhoeven)

   - Update the cpupower utility to fix lib version-ing in it and memory
     leaks in error legs, remove hard-coded values, and implement CPU
     physical core querying (Thomas Renninger, John B. Wyatt IV, Shuah

Pull ACPI updates from Rafael Wysocki:
 "From the functional perspective, the most significant changes here are
  the ACPI fan driver update allowing it to handle fans with
  fine-grained state checking supported, but without fine-grained
  control, and the ACPI button driver update making it subscribe to
  system event notifications (in addition to device notifications) which
  on some systems is requisite for waking up the system from sleep.

  The rest is fixes and cleanups including removal of some dead code.

  Specifics:

   - Use the str_on_off() helper function instead of hard-coded strings
     in the ACPI power resources handling code (Thorsten Blum)

   - Add fan speed reporting for ACPI fans that have _FST, but otherwise
     do not support the entire ACPI 4 fan interface (Joshua Grisham)

Pull kvm updates from Paolo Bonzini:
 "ARM:

   - Nested virtualization support for VGICv3, giving the nested
     hypervisor control of the VGIC hardware when running an L2 VM

   - Removal of 'late' nested virtualization feature register masking,
     making the supported feature set directly visible to userspace

   - Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
     of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers

   - Paravirtual interface for discovering the set of CPU
     implementations where a VM may run, addressing a longstanding issue
     of guest CPU errata awareness in big-little systems and
     cross-implementation VM migration

   - Userspace control of the registers responsible for identifying a
     particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
     allowing VMs to be migrated cross-implementation

   - pKVM updates, including support for tracking stage-2 page table
     allocations in the protected hypervisor in the 'SecPageTable' stat

   - Fixes to vPMU, ensuring that userspace updates to the vPMU after
     KVM_RUN are reflected into the backing perf events

  LoongArch:

   - Remove unnecessary header include path

   - Assume constant PGD during VM context switch

   - Add perf events support for guest VM

  RISC-V:

   - Disable the kernel perf counter during configure

   - KVM selftests improvements for PMU

   - Fix warning at the time of KVM module removal

  x86:

   - Add support for aging of SPTEs without holding mmu_lock.

     Not taking mmu_lock allows multiple aging actions to run in
     parallel, and more importantly avoids stalling vCPUs. This includes
     an implementation of per-rmap-entry locking; aging the gfn is done
     with only a per-rmap single-bin spinlock taken, whereas locking an
     rmap for write requires taking both the per-rmap spinlock and the
     mmu_lock.

     Note that this decreases slightly the accuracy of accessed-page
     information, because changes to the SPTE outside aging might not
     use atomic operations even if they could race against a clear of
     the Accessed bit.

     This is deliberate because KVM and mm/ tolerate false
     positives/negatives for accessed information, and testing has shown
     that reducing the latency of aging is far more beneficial to
     overall system performance than providing "perfect" young/old
     information.

   - Defer runtime CPUID updates until KVM emulates a CPUID instruction,
     to coalesce updates when multiple pieces of vCPU state are
     changing, e.g. as part of a nested transition

   - Fix a variety of nested emulation bugs, and add VMX support for
     synthesizing nested VM-Exit on interception (instead of injecting
     #UD into L2)

   - Drop "support" for async page faults for protected guests that do
     not set SEND_ALWAYS (i.e. that only want async page faults at CPL3)

   - Bring a bit of sanity to x86's VM teardown code, which has
     accumulated a lot of cruft over the years. Particularly, destroy
     vCPUs before the MMU, despite the latter being a VM-wide operation

   - Add common secure TSC infrastructure for use within SNP and in the
     future TDX

   - Block KVM_CAP_SYNC_REGS if guest state is protected. It does not
     make sense to use the capability if the relevant registers are not
     available for reading or writing

   - Don't take kvm->lock when iterating over vCPUs in the suspend
     notifier to fix a largely theoretical deadlock

   - Use the vCPU's actual Xen PV clock information when starting the
     Xen timer, as the cached state in arch.hv_clock can be stale/bogus

   - Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across
     different PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as
     KVM's suspend notifier only accounts for kvmclock, and there's no
     evidence that the flag is actually supported by Xen guests

   - Clean up the per-vCPU "cache" of its reference pvclock, and instead
     only track the vCPU's TSC scaling (multipler+shift) metadata (which
     is moderately expensive to compute, and rarely changes for modern
     setups)

   - Don't write to the Xen hypercall page on MSR writes that are
     initiated by the host (userspace or KVM) to fix a class of bugs
     where KVM can write to guest memory at unexpected times, e.g.
     during vCPU creation if userspace has set the Xen hypercall MSR
     index to collide with an MSR that KVM emulates

   - Restrict the Xen hypercall MSR index to the unofficial synthetic
     range to reduce the set of possible collisions with MSRs that are
     emulated by KVM (collisions can still happen as KVM emulates
     Hyper-V MSRs, which also reside in the synthetic range)

   - Clean up and optimize KVM's handling of Xen MSR writes and
     xen_hvm_config

   - Update Xen TSC leaves during CPUID emulation instead of modifying
     the CPUID entries when updating PV clocks; there is no guarantee PV
     clocks will be updated between TSC frequency changes and CPUID
     emulation, and guest reads of the TSC leaves should be rare, i.e.
     are not a hot path

  x86 (Intel):

   - Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and
     thus modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1

   - Pass XFD_ERR as the payload when injecting #NM, as a preparatory
     step for upcoming FRED virtualization support

   - Decouple the EPT entry RWX protection bit macros from the EPT
     Violation bits, both as a general cleanup and in anticipation of
     adding support for emulating Mode-Based Execution Control (MBEC)

   - Reject KVM_RUN if userspace manages to gain control and stuff
     invalid guest state while KVM is in the middle of emulating nested
     VM-Enter

   - Add a macro to handle KVM's sanity checks on entry/exit VMCS
     control pairs in anticipation of adding sanity checks for secondary
     exit controls (the primary field is out of bits)

  x86 (AMD):

   - Ensure the PSP driver is initialized when both the PSP and KVM
     modules are built-in (the initcall framework doesn't handle
     dependencies)

   - Use long-term pins when registering encrypted memory regions, so
     that the pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and
     don't lead to excessive fragmentation

   - Add macros and helpers for setting GHCB return/error codes

   - Add support for Idle HLT interception, which elides interception if
     the vCPU has a pending, unmasked virtual IRQ when HLT is executed

   - Fix a bug in INVPCID emulation where KVM fails to check for a
     non-canonical address

   - Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is
     invalid, e.g. because the vCPU was "destroyed" via SNP's AP
     Creation hypercall

   - Reject SNP AP Creation if the requested SEV features for the vCPU
     don't match the VM's configured set of features

  Selftests:

   - Fix again the Intel PMU counters test; add a data load and do
     CLFLUSH{OPT} on the data instead of executing code. The theory is
     that modern Intel CPUs have learned new code prefetching tricks
     that bypass the PMU counters

   - Fix a flaw in the Intel PMU counters test where it asserts that an
     event is counting correctly without actually knowing what the event
     counts on the underlying hardware

   - Fix a variety of flaws, bugs, and false failures/passes
     dirty_log_test, and improve its coverage by collecting all dirty
     entries on each iteration

   - Fix a few minor bugs related to handling of stats FDs

   - Add infrastructure to make vCPU and VM stats FDs available to tests
     by default (open the FDs during VM/vCPU creation)

   - Relax an assertion on the number of HLT exits in the xAPIC IPI test
     when running on a CPU that supports AMD's Idle HLT (which elides
     interception of HLT if a virtual IRQ is pending and unmasked)"

Pull VDSO infrastructure updates from Thomas Gleixner:

 - Consolidate the VDSO storage

   The VDSO data storage and data layout has been largely architecture
   specific for historical reasons. That increases the maintenance
   effort and causes inconsistencies over and over.

   There is no real technical reason for architecture specific layouts
   and implementations. The architecture specific details can easily be
   integrated into a generic layout, which also reduces the amount of
   duplicated code for managing the mappings.

   Convert all architectures over to a unified layout and common mapping
   infrastructure. This splits the VDSO data layout into subsystem
   specific blocks, timekeeping, random and architecture parts, which
   provides a better structure and allows to improve and update the
   functionalities without conflict and interaction.

 - Rework the timekeeping data storage

   The current implementation is designed for exposing system
   timekeeping accessors, which was good enough at the time when it was
   designed.

   PTP and Time Sensitive Networking (TSN) change that as there are
   requirements to expose independent PTP clocks, which are not related
   to system timekeeping.

   Replace the monolithic data storage by a structured layout, which
   allows to add support for independent PTP clocks on top while reusing
   both the data structures and the time accessor implementations.

Pull timer cleanups from Thomas Gleixner:
 "A treewide hrtimer timer cleanup

  hrtimers are initialized with hrtimer_init() and a subsequent store to
  the callback pointer. This turned out to be suboptimal for the
  upcoming Rust integration and is obviously a silly implementation to
  begin with.

  This cleanup replaces the hrtimer_init(T); T->function = cb; sequence
  with hrtimer_setup(T, cb);

  The conversion was done with Coccinelle and a few manual fixups.

  Once the conversion has completely landed in mainline, hrtimer_init()
  will be removed and the hrtimer::function becomes a private member"

Pull timer core updates from Thomas Gleixner:

 - Fix a memory ordering issue in posix-timers

   Posix-timer lookup is lockless and reevaluates the timer validity
   under the timer lock, but the update which validates the timer is not
   protected by the timer lock. That allows the store to be reordered
   against the initialization stores, so that the lookup side can
   observe a partially initialized timer. That's mostly a theoretical
   problem, but incorrect nevertheless.

 - Fix a long standing inconsistency of the coarse time getters

   The coarse time getters read the base time of the current update
   cycle without reading the actual hardware clock. NTP frequency
   adjustment can set the base time backwards. The fine grained
   interfaces compensate this by reading the clock and applying the new
   conversion factor, but the coarse grained time getters use the base
   time directly. That allows the user to observe time going backwards.

   Cure it by always forwarding base time, when NTP changes the
   frequency with an immediate step.

 - Rework of posix-timer hashing

   The posix-timer hash is not scalable and due to the CRIU timer
   restore mechanism prone to massive contention on the global hash
   bucket lock.

   Replace the global hash lock with a fine grained per bucket locking
   scheme to address that.

 - Rework the proc/$PID/timers interface.

   /proc/$PID/timers is provided for CRIU to be able to restore a timer.
   The printout happens with sighand lock held and interrupts disabled.
   That's not required as this can be done with RCU protection as well.

 - Provide a sane mechanism for CRIU to restore a timer ID

   CRIU restores timers by creating and deleting them until the kernel
   internal per process ID counter reached the requested ID. That's
   horribly slow for sparse timer IDs.

   Provide a prctl() which allows CRIU to restore a timer with a given
   ID. When enabled the ID pointer is used as input pointer to read the
   requested ID from user space. When disabled, the normal allocation
   scheme (next ID) is active as before. This is backwards compatible
   for both kernel and user space.

 - Make hrtimer_update_function() less expensive.

   The sanity checks are valuable, but expensive for high frequency
   usage in io/uring. Make the debug checks conditional and enable them
   only when lockdep is enabled.

 - Small updates, cleanups and improvements

Pull irq driver updates from Thomas Gleixner:

 - Support for hard indices on RISC-V. The hart index identifies a hart
   (core) within a specific interrupt domain in RISC-V's Priviledged
   Architecture.

 - Rework of the RISC-V MSI driver

   This moves the driver over to the generic MSI library and solves the
   affinity problem of unmaskable PCI/MSI controllers. Unmaskable
   PCI/MSI controllers are prone to lose interrupts when the MSI message
   is updated to change the affinity because the message write consists
   of three 32-bit subsequent writes, which update address and data. As
   these writes are non-atomic versus the device raising an interrupt,
   the device can observe a half written update and issue an interrupt
   on the wrong vector. This is mitiated by a carefully orchestrated
   step by step update and the observation of an eventually pending
   interrupt on the CPU which issues the update. The algorithm follows
   the well established method of the X86 MSI driver.

 - A new driver for the RISC-V Sophgo SG2042 MSI controller

 - Overhaul of the Renesas RZQ2L driver

   Simplification of the probe function by using devm_*() mechanisms,
   which avoid the endless list of error prone gotos in the failure
   paths.

 - Expand the Renesas RZV2H driver to support RZ/G3E SoCs

 - A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to
   ensure that the addressing is limited to the lower 32-bit of the
   physical address space.

 - Add support for the Allwinner AS23 NMI controller

 - Expand the IMX irqsteer driver to handle up to 960 input interrupts

 - The usual small updates, cleanups and device tree changes

We've had this before: when we remove infrastructure to generate files,
the old stale build artifacts still remain in-tree.  And when the
infrastructure to generate them is gone, so is the gitignore file for
those build artifacts.

End result: git will see the old generated files, and people will
mistakenly commit them.  That's what happened with the 'genheaders' file
not that long ago (see commit 04a3389b "Remove stale generated
'genheaders' file").

This time it's commit 9c54baab ("x86/boot: Drop CRC-32 checksum and
the build tool that generates it") that removed the 'build' file from
the arch/x86/boot/tools/ subdirectory, and removed the .gitignore file
too (because the whole subdirectory is gone).

And as a result, if you don't do a 'git clean -dqfx' or similar to clean
up your tree, 'git status' will say

  Untracked files:
    (use "git add <file>..." to include in what will be committed)
	arch/x86/boot/tools/

and some hapless sleep-deprived developer will inevitably decide that
that means that they need to 'git add' that directory.  Which would
bring back some stale generated file that we most definitely do not want
in the tree.

So when removing directories that had special .gitignore patterns, make
sure to add a new gitignore entry in the parent directory for the no
longer existing subdirectory.

It will avoid mistakes.

Pull scheduler updates from Ingo Molnar:
 "Core & fair scheduler changes:

   - Cancel the slice protection of the idle entity (Zihan Zhou)
   - Reduce the default slice to avoid tasks getting an extra tick
     (Zihan Zhou)
   - Force propagating min_slice of cfs_rq when {en,de}queue tasks
     (Tianchen Ding)
   - Refactor can_migrate_task() to elimate looping (I Hsin Cheng)
   - Add unlikey branch hints to several system calls (Colin Ian King)
   - Optimize current_clr_polling() on certain architectures (Yujun
     Dong)

  Deadline scheduler: (Juri Lelli)
   - Remove redundant dl_clear_root_domain call
   - Move dl_rebuild_rd_accounting to cpuset.h

  Uclamp:
   - Use the uclamp_is_used() helper instead of open-coding it (Xuewen
     Yan)
   - Optimize sched_uclamp_used static key enabling (Xuewen Yan)

  Scheduler topology support: (Juri Lelli)
   - Ignore special tasks when rebuilding domains
   - Add wrappers for sched_domains_mutex
   - Generalize unique visiting of root domains
   - Rebuild root domain accounting after every update
   - Remove partition_and_rebuild_sched_domains
   - Stop exposing partition_sched_domains_locked

  RSEQ: (Michael Jeanson)
   - Update kernel fields in lockstep with CONFIG_DEBUG_RSEQ=y
   - Fix segfault on registration when rseq_cs is non-zero
   - selftests: Add rseq syscall errors test
   - selftests: Ensure the rseq ABI TLS is actually 1024 bytes

  Membarriers:
   - Fix redundant load of membarrier_state (Nysal Jan K.A.)

  Scheduler debugging:
   - Introduce and use preempt_model_str() (Sebastian Andrzej Siewior)
   - Make CONFIG_SCHED_DEBUG unconditional (Ingo Molnar)

  Fixes and cleanups:
   - Always save/restore x86 TSC sched_clock() on suspend/resume
     (Guilherme G. Piccoli)
   - Misc fixes and cleanups (Thorsten Blum, Juri Lelli, Sebastian
     Andrzej Siewior)"

Pull objtool updates from Ingo Molnar:

 - The biggest change is the new option to automatically fail the build
   on objtool warnings: CONFIG_OBJTOOL_WERROR.

   While there are no currently known unfixed false positives left, such
   an expansion in the severity of objtool warnings inevitably creates a
   risk of build failures, so it's disabled by default and depends on
   !COMPILE_TEST, so it shouldn't be enabled on
   allyesconfig/allmodconfig builds and won't be forced on people who
   just accept build-time defaults in 'make oldconfig'.

   While the option is strongly recommended, only people who enable it
   explicitly should see it.

   (Josh Poimboeuf)

 - Disable branch profiling in noinstr code with a broad brush that
   includes all of arch/x86/ and kernel/sched/. (Josh Poimboeuf)

 - Create backup object files on objtool errors and print exact objtool
   arguments to make failure analysis easier (Josh Poimboeuf)

 - Improve noreturn handling (Josh Poimboeuf)

 - Improve rodata handling (Tiezhu Yang)

 - Support jump tables, switch tables and goto tables on LoongArch
   (Tiezhu Yang)

 - Misc cleanups and fixes (Josh Poimboeuf, David Engraf, Ingo Molnar)
