Pull landlock updates from Mickaël Salaün:
 "Add support for Landlock to UML.

  To do this, this fixes the way hostfs manages inodes according to the
  underlying filesystem [1]. They are now properly handled as for other
  filesystems, which enables Landlock support (and probably other
  features).

  This also extends Landlock's tests with 6 pseudo filesystems,
  including hostfs"

6e2332e0ab cgroup: Changes for v6.5
* Whenever cpuset needs to rebuild sched_domain, it walked all tasks looking
   for DEADLINE tasks as they need to be accounted on the new domain. Walking
   all tasks can be expensive and there may not be any DEADLINE tasks at all.
   Task iteration is now omitted if there are no DEADLINE tasks.
 
 * Fixes DEADLINE bandwidth misaccounting after task migration failures.
 
 * When no controller is enabled, -Wstringop-overflow warning is triggered.
   The fix patch added an early exit which is too eager and got reverted for
   now. Will fix later.
 
 * Everything else are minor cleanups.

72dc6db7e3 workqueue: Ordered workqueue creation cleanups
For historical reasons, unbound workqueues with max concurrency limit of 1
 are considered ordered, even though the concurrency limit hasn't been
 system-wide for a long time. This creates ambiguity around whether ordered
 execution is actually required for correctness, which was actually confusing
 for e.g. btrfs (btrfs updates are being routed through the btrfs tree).
 
 There aren't that many users in the tree which use the combination and there
 are pending improvements to unbound workqueue affinity handling which will
 make inadvertent use of ordered workqueue a bigger loss. This pull request
 clarifies the situation for most of them by updating the ones which require
 ordered execution to use alloc_ordered_workqueue().
 
 There are some conversions being routed through subsystem-specific trees and
 likely a few stragglers. Once they're all converted, workqueue can trigger a
 warning on unbound + @max_active==1 usages and eventually drop the implicit
 ordered behavior.

7ab044a4f4 workqueue: Changes for v6.5
* Concurrency-managed per-cpu work items that hog CPUs and delay the
   execution of other work items are now automatically detected and excluded
   from concurrency management. Reporting on such work items can also be
   enabled through a config option.
 
 * Added tools/workqueue/wq_monitor.py which improves visibility into

 * Includes Arnd's minimal fix for gcc-13 enum warning on 32bit compiles.
   This conflicts with afa4bb778e ("workqueue: clean up WORK_* constant
   types, clarify masking") in master. Can be resolved by picking the master

6a46676994 s390 updates for 6.5 merge window
- Fix the style of protected key API driver source: use
   x-mas tree for all local variable declarations.
 
 - Rework protected key API driver to not use the struct
   pkey_protkey and pkey_clrkey anymore. Both structures
   have a fixed size buffer, but with the support of ECC
   protected key these buffers are not big enough. Use
   dynamic buffers internally and transparently for
   userspace.
 
 - Add support for a new 'non CCA clear key token' with
   ECC clear keys supported: ECC P256, ECC P384, ECC P521,
   ECC ED25519 and ECC ED448. This makes it possible to
   derive a protected key from the ECC clear key input via
   PKEY_KBLOB2PROTK3 ioctl, while currently the only way
   to derive is via PCKMO instruction.
 
 - The s390 PMU of PAI crypto and extension 1 NNPA counters
   use atomic_t for reference counting. Replace this with
   the proper data type refcount_t.
 
 - Select ARCH_SUPPORTS_INT128, but limit this to clang for
   now, since gcc generates inefficient code, which may lead
   to stack overflows.
 
 - Replace one-element array with flexible-array member in
   struct vfio_ccw_parent and refactor the rest of the code
   accordingly. Also, prefer struct_size() over sizeof() open-
   coded versions.
 
 - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and
   OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether
   the system memory should be cleared or not once dumped.
 
 - Fix a hang when a user attempts to remove a VFIO-AP mediated
   device attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and
   VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver
   callback to request a release of the device.
 
 - Fix calculation for R_390_GOTENT relocations for modules.
 
 - Allow any user space process with CAP_PERFMON capability
   read and display the CPU Measurement facility counter sets.
 
 - Rework large statically-defined per-CPU cpu_cf_events data
   structure and replace it with dynamically allocated structures
   created when a perf_event_open() system call is invoked or
   /dev/hwctr device is accessed.

to go together with a patchset that Vishal Moola had planned taking it
through the mm tree. By just having this patch, all NIOS2 builds are

6f612579be objtool changes for v6.5:
- Build footprint & performance improvements:
 
     - Reduce memory usage with CONFIG_DEBUG_INFO=y
 
       In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel, DWARF
       creates almost 200 million relocations, ballooning objtool's peak heap
       usage to 53GB.  These patches reduce that to 25GB.
 
       On a distro-type kernel with kernel IBT enabled, they reduce objtool's
       peak heap usage from 4.2GB to 2.8GB.
 
       These changes also improve the runtime significantly.
 
 - Debuggability improvements:
 
     - Add the unwind_debug command-line option, for more extend unwinding
       debugging output.
     - Limit unreachable warnings to once per function
     - Add verbose option for disassembling affected functions
     - Include backtrace in verbose mode
     - Detect missing __noreturn annotations
     - Ignore exc_double_fault() __noreturn warnings
     - Remove superfluous global_noreturns entries
     - Move noreturn function list to separate file
     - Add __kunit_abort() to noreturns
 
 - Unwinder improvements:
 
     - Allow stack operations in UNWIND_HINT_UNDEFINED regions
     - drm/vmwgfx: Add unwind hints around RBP clobber
 
 - Cleanups:
 
     - Move the x86 entry thunk restore code into thunk functions
     - x86/unwind/orc: Use swap() instead of open coding it
     - Remove unnecessary/unused variables
 
 - Fixes for modern stack canary handling

Pull objtool updates from Ingo Molar:
 "Build footprint & performance improvements:

   - Reduce memory usage with CONFIG_DEBUG_INFO=y

     In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel,
     DWARF creates almost 200 million relocations, ballooning objtool's
     peak heap usage to 53GB. These patches reduce that to 25GB.

     On a distro-type kernel with kernel IBT enabled, they reduce
     objtool's peak heap usage from 4.2GB to 2.8GB.

     These changes also improve the runtime significantly.

  Debuggability improvements:

   - Add the unwind_debug command-line option, for more extend unwinding
     debugging output
   - Limit unreachable warnings to once per function
   - Add verbose option for disassembling affected functions
   - Include backtrace in verbose mode
   - Detect missing __noreturn annotations
   - Ignore exc_double_fault() __noreturn warnings
   - Remove superfluous global_noreturns entries
   - Move noreturn function list to separate file
   - Add __kunit_abort() to noreturns

  Unwinder improvements:

   - Allow stack operations in UNWIND_HINT_UNDEFINED regions
   - drm/vmwgfx: Add unwind hints around RBP clobber

  Cleanups:

   - Move the x86 entry thunk restore code into thunk functions
   - x86/unwind/orc: Use swap() instead of open coding it
   - Remove unnecessary/unused variables

  Fixes for modern stack canary handling"

   of a 6-parameter horror that forced u128 - u64/u64-halves layout

ed3b7923a8 Scheduler changes for v6.5:
- Scheduler SMP load-balancer improvements:
 
     - Avoid unnecessary migrations within SMT domains on hybrid systems.
 
       Problem:
 
         On hybrid CPU systems, (processors with a mixture of higher-frequency
 	SMT cores and lower-frequency non-SMT cores), under the old code
 	lower-priority CPUs pulled tasks from the higher-priority cores if
 	more than one SMT sibling was busy - resulting in many unnecessary
 	task migrations.
 
       Solution:
 
         The new code improves the load balancer to recognize SMT cores with more
         than one busy sibling and allows lower-priority CPUs to pull tasks, which
         avoids superfluous migrations and lets lower-priority cores inspect all SMT
         siblings for the busiest queue.
 
     - Implement the 'runnable boosting' feature in the EAS balancer: consider CPU
       contention in frequency, EAS max util & load-balance busiest CPU selection.
 
       This improves CPU utilization for certain workloads, while leaves other key
       workloads unchanged.
 
 - Scheduler infrastructure improvements:
 
     - Rewrite the scheduler topology setup code by consolidating it
       into the build_sched_topology() helper function and building
       it dynamically on the fly.
 
     - Resolve the local_clock() vs. noinstr complications by rewriting
       the code: provide separate sched_clock_noinstr() and
       local_clock_noinstr() functions to be used in instrumentation code,
       and make sure it is all instrumentation-safe.
 
 - Fixes:
 
     - Fix a kthread_park() race with wait_woken()
 
     - Fix misc wait_task_inactive() bugs unearthed by the -rt merge:
        - Fix UP PREEMPT bug by unifying the SMP and UP implementations.
        - Fix task_struct::saved_state handling.
 
     - Fix various rq clock update bugs, unearthed by turning on the rq clock
       debugging code.
 
     - Fix the PSI WINDOW_MIN_US trigger limit, which was easy to trigger by
       creating enough cgroups, by removing the warnign and restricting
       window size triggers to PSI file write-permission or CAP_SYS_RESOURCE.
 
     - Propagate SMT flags in the topology when removing degenerate domain
 
     - Fix grub_reclaim() calculation bug in the deadline scheduler code
 
     - Avoid resetting the min update period when it is unnecessary, in
       psi_trigger_destroy().
 
     - Don't balance a task to its current running CPU in load_balance(),
       which was possible on certain NUMA topologies with overlapping
       groups.
 
     - Fix the sched-debug printing of rq->nr_uninterruptible
 
 - Cleanups:
 
     - Address various -Wmissing-prototype warnings, as a preparation
       to (maybe) enable this warning in the future.
 
     - Remove unused code
 
     - Mark more functions __init

af96134dc8 RCU pull request for v6.5
This pull contains the following branches:
 
 doc.2023.05.10a: Documentation updates
 
 fixes.2023.05.11a: Miscellaneous fixes, perhaps most notably:
 
 o	Remove RCU_NONIDLE().  The new visibility of most of the idle
 	loop to RCU has obsoleted this API.
 
 o	Make the RCU_SOFTIRQ callback-invocation time limit also apply
 	to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
 
 o	Add a jiffies-based callback-invocation time limit to handle
 	long-running callbacks.  (The local_clock() function is only
 	invoked once per 32 callbacks due to its high overhead.)
 
 o	Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs,
 	which fixes a bug that can occur on systems with non-contiguous
 	CPU numbering.
 
 kvfree.2023.05.10a: kvfree_rcu updates
 
 o	Eliminate the single-argument variant of k[v]free_rcu() now
 	that all uses have been converted to k[v]free_rcu_mightsleep().
 
 o	Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks
 	too soon.  Yes, this is closing the barn door after the horse
 	has escaped, but Murphy says that there will be more horses.

     to capture EC coredumps (LPC interface only).
   - Send EC_CMD_HOST_SLEEP_EVENT to EC at the very beginning/end of
     system suspend/resume so that EC can watch the duration more
     accurately (LPC interface only).
 
 * Misc

40e8e98f51 Power management updates for 6.5-rc1
- Introduce power capping core support for Intel TPMI (Topology Aware
    Register and PM Capsule Interface) and a TPMI interface driver for
    Intel RAPL (Zhang Rui, Dan Carpenter).
 
  - Fix CONFIG_IOSF_MBI dependency in the Intel RAPL power capping
    driver (Zhang Rui).
 
  - Fix invalid initialization for pl4_supported field in the Intel RAPL
    power capping driver (Sumeet Pawnikar).
 
  - Clean up the intel_idle driver, make it work with VM guests that
    cannot use the MWAIT instruction and address the case in which the
    host may enter a deep idle state when the guest is idle (Arjan van
    de Ven).
 
  - Prevent cpufreq drivers that provide the ->adjust_perf() callback
    without a ->fast_switch() one which is used as a fallback from the
    former in some cases (Wyes Karny).
 
  - Fix some issues related to the AMD P-state cpufreq driver (Mario
    Limonciello, Wyes Karny).
 
  - Fix the energy_performance_preference attribute handling in the
    intel_pstate driver in passive mode (Tero Kristo).
 
  - Fix the handling of pm_suspend_target_state when CONFIG_PM is unset
    (Kai-Heng Feng).
 
  - Correct spelling mistake in a comment in the hibernation code (Wang
    Honghui).
 
  - Add arch_resume_nosmt() prototype to avoid a "missing prototypes"
    build warning (Arnd Bergmann).
 
  - Restrict pm_pr_dbg() to system-wide power transitions and use it in
    a few additional places (Mario Limonciello).
 
  - Drop verification of in-params from genpd_add_device() and ensure
    that all of its callers will do it (Ulf Hansson).
 
  - Prevent possible integer overflows from occurring in
    genpd_parse_state() (Nikita Zhandarovich).
 
  - Reorder fieldls in 'struct devfreq_dev_status' to reduce its size
    somewhat (Christophe JAILLET).
 
  - Ensure that the Exynos PPMU driver is already loaded before the
    Exynos Bus driver starts probing so as to avoid a possible freeze
    loading of the kernel modules (Marek Szyprowski).
 
  - Fix variable deferencing before NULL check in the mtk-cci devfreq
    driver (Sukrut Bellary).

   - Introduce power capping core support for Intel TPMI (Topology Aware
     Register and PM Capsule Interface) and a TPMI interface driver for
     Intel RAPL (Zhang Rui, Dan Carpenter)

   - Fix CONFIG_IOSF_MBI dependency in the Intel RAPL power capping
     driver (Zhang Rui)

   - Fix invalid initialization for pl4_supported field in the Intel
     RAPL power capping driver (Sumeet Pawnikar)

   - Clean up the intel_idle driver, make it work with VM guests that
     cannot use the MWAIT instruction and address the case in which the
     host may enter a deep idle state when the guest is idle (Arjan van
     de Ven)

   - Prevent cpufreq drivers that provide the ->adjust_perf() callback
     without a ->fast_switch() one which is used as a fallback from the
     former in some cases (Wyes Karny)

   - Fix some issues related to the AMD P-state cpufreq driver (Mario
     Limonciello, Wyes Karny)

   - Fix the energy_performance_preference attribute handling in the
     intel_pstate driver in passive mode (Tero Kristo)

   - Fix the handling of pm_suspend_target_state when CONFIG_PM is unset
     (Kai-Heng Feng)

   - Correct spelling mistake in a comment in the hibernation code (Wang
     Honghui)

   - Add arch_resume_nosmt() prototype to avoid a "missing prototypes"
     build warning (Arnd Bergmann)

   - Restrict pm_pr_dbg() to system-wide power transitions and use it in
     a few additional places (Mario Limonciello)

   - Drop verification of in-params from genpd_add_device() and ensure
     that all of its callers will do it (Ulf Hansson)

   - Prevent possible integer overflows from occurring in
     genpd_parse_state() (Nikita Zhandarovich)

   - Reorder fieldls in 'struct devfreq_dev_status' to reduce its size
     somewhat (Christophe JAILLET)

   - Ensure that the Exynos PPMU driver is already loaded before the
     Exynos Bus driver starts probing so as to avoid a possible freeze
     loading of the kernel modules (Marek Szyprowski)

   - Fix variable deferencing before NULL check in the mtk-cci devfreq
     driver (Sukrut Bellary)"

Pull x86 tdx updates from Dave Hansen:

 - Fix a race window where load_unaligned_zeropad() could cause a fatal
   shutdown during TDX private<=>shared conversion

   The race has never been observed in practice but might allow
   load_unaligned_zeropad() to catch a TDX page in the middle of its
   conversion process which would lead to a fatal and unrecoverable
   guest shutdown.

 - Annotate sites where VM "exit reasons" are reused as hypercall

 - Add initial support for RAS hardware found on AMD server GPUs (MI200).

   Those GPUs and CPUs are connected together through the coherent
   fabric and the GPU memory controllers report errors through x86's MCA
   so EDAC needs to support them. The amd64_edac driver supports now HBM
   (High Bandwidth Memory) and thus such heterogeneous memory controller
   systems

 - Other small cleanups and improvements

88afbb21d4 A set of fixes for kexec(), reboot and shutdown issues
- Ensure that the WBINVD in stop_this_cpu() has been completed before the
    control CPU proceedes.
 
    stop_this_cpu() is used for kexec(), reboot and shutdown to park the APs
    in a HLT loop.
 
    The control CPU sends an IPI to the APs and waits for their CPU online bits
    to be cleared. Once they all are marked "offline" it proceeds.
 
    But stop_this_cpu() clears the CPU online bit before issuing WBINVD,
    which means there is no guarantee that the AP has reached the HLT loop.
 
    This was reported to cause intermittent reboot/shutdown failures due to
    some dubious interaction with the firmware.
 
    This is not only a problem of WBINVD. The code to actually "stop" the
    CPU which runs between clearing the online bit and reaching the HLT loop
    can cause large enough delays on its own (think virtualization). That's
    especially dangerous for kexec() as kexec() expects that all APs are in
    a safe state and not executing code while the boot CPU jumps to the new
    kernel. There are more issues vs. kexec() which are addressed separately.
 
    Cure this by implementing an explicit synchronization point right before
    the AP reaches HLT. This guarantees that the AP has completed the full
    stop proceedure.
 
  - Fix the condition for WBINVD in stop_this_cpu().
 
    The WBINVD in stop_this_cpu() is required for ensuring that when
    switching to or from memory encryption no dirty data is left in the
    cache lines which might cause a write back in the wrong more later.
 
    This checks CPUID directly because the feature bit might have been
    cleared due to a command line option.
 
    But that CPUID check accesses leaf 0x8000001f::EAX unconditionally. Intel
    CPUs return the content of the highest supported leaf when a non-existing
    leaf is read, while AMD CPUs return all zeros for unsupported leafs.
 
    So the result of the test on Intel CPUs is lottery and on AMD its just
    correct by chance.
 
    While harmless it's incorrect and causes the conditional wbinvd() to be
    issued where not required, which caused the above issue to be unearthed.
 
  - Make kexec() robust against AP code execution
 
    Ashok observed triple faults when doing kexec() on a system which had
    been booted with "nosmt".
 
    It turned out that the SMT siblings which had been brought up partially
    are parked in mwait_play_dead() to enable power savings.
 
    mwait_play_dead() is monitoring the thread flags of the AP's idle task,
    which has been chosen as it's unlikely to be written to.
 
    But kexec() can overwrite the previous kernel text and data including
    page tables etc. When it overwrites the cache lines monitored by an AP
    that AP resumes execution after the MWAIT on eventually overwritten
    text, stack and page tables, which obviously might end up in a triple
    fault easily.
 
    Make this more robust in several steps:
 
     1) Use an explicit per CPU cache line for monitoring.
 
     2) Write a command to these cache lines to kick APs out of MWAIT before
        proceeding with kexec(), shutdown or reboot.
 
        The APs confirm the wakeup by writing status back and then enter a
        HLT loop.
 
     3) If the system uses INIT/INIT/STARTUP for AP bringup, park the APs
        in INIT state.
 
        HLT is not a guarantee that an AP won't wake up and resume
        execution. HLT is woken up by NMI and SMI. SMI puts the CPU back
        into HLT (+/- firmware bugs), but NMI is delivered to the CPU which
        executes the NMI handler. Same issue as the MWAIT scenario described
        above.
 
        Sending an INIT/INIT sequence to the APs puts them into wait for
        STARTUP state, which is safe against NMI.
 
     There is still an issue remaining which can't be fixed: #MCE
 
     If the AP sits in HLT and receives a broadcast #MCE it will try to
     handle it with the obvious consequences.
 
     INIT/INIT clears CR4.MCE in the AP which will cause a broadcast #MCE to
     shut down the machine.
 
     So there is a choice between fire (HLT) and frying pan (INIT). Frying
     pan has been chosen as it's at least preventing the NMI issue.
 
     On systems which are not using INIT/INIT/STARTUP there is not much
     which can be done right now, but at least the obvious and easy to
     trigger MWAIT issue has been addressed.

9244724fbf A large update for SMP management:
- Parallel CPU bringup
 
     The reason why people are interested in parallel bringup is to shorten
     the (kexec) reboot time of cloud servers to reduce the downtime of the
     VM tenants.
 
     The current fully serialized bringup does the following per AP:
 
       1) Prepare callbacks (allocate, intialize, create threads)
       2) Kick the AP alive (e.g. INIT/SIPI on x86)
       3) Wait for the AP to report alive state
       4) Let the AP continue through the atomic bringup
       5) Let the AP run the threaded bringup to full online state
 
     There are two significant delays:
 
       #3 The time for an AP to report alive state in start_secondary() on
          x86 has been measured in the range between 350us and 3.5ms
          depending on vendor and CPU type, BIOS microcode size etc.
 
       #4 The atomic bringup does the microcode update. This has been
          measured to take up to ~8ms on the primary threads depending on
          the microcode patch size to apply.
 
     On a two socket SKL server with 56 cores (112 threads) the boot CPU
     spends on current mainline about 800ms busy waiting for the APs to come
     up and apply microcode. That's more than 80% of the actual onlining
     procedure.
 
     This can be reduced significantly by splitting the bringup mechanism
     into two parts:
 
       1) Run the prepare callbacks and kick the AP alive for each AP which
       	 needs to be brought up.
 
 	 The APs wake up, do their firmware initialization and run the low
       	 level kernel startup code including microcode loading in parallel
       	 up to the first synchronization point. (#1 and #2 above)
 
       2) Run the rest of the bringup code strictly serialized per CPU
       	 (#3 - #5 above) as it's done today.
 
 	 Parallelizing that stage of the CPU bringup might be possible in
 	 theory, but it's questionable whether required surgery would be
 	 justified for a pretty small gain.
 
     If the system is large enough the first AP is already waiting at the
     first synchronization point when the boot CPU finished the wake-up of
     the last AP. That reduces the AP bringup time on that SKL from ~800ms
     to ~80ms, i.e. by a factor ~10x.
 
     The actual gain varies wildly depending on the system, CPU, microcode
     patch size and other factors. There are some opportunities to reduce
     the overhead further, but that needs some deep surgery in the x86 CPU
     bringup code.
 
     For now this is only enabled on x86, but the core functionality
     obviously works for all SMP capable architectures.
 
   - Enhancements for SMP function call tracing so it is possible to locate
     the scheduling and the actual execution points. That allows to measure
     IPI delivery time precisely.

Pull SMP updates from Thomas Gleixner:
 "A large update for SMP management:

   - Parallel CPU bringup

     The reason why people are interested in parallel bringup is to
     shorten the (kexec) reboot time of cloud servers to reduce the
     downtime of the VM tenants.

     The current fully serialized bringup does the following per AP:

       1) Prepare callbacks (allocate, intialize, create threads)
       2) Kick the AP alive (e.g. INIT/SIPI on x86)
       3) Wait for the AP to report alive state
       4) Let the AP continue through the atomic bringup
       5) Let the AP run the threaded bringup to full online state

     There are two significant delays:

       #3 The time for an AP to report alive state in start_secondary()
          on x86 has been measured in the range between 350us and 3.5ms
          depending on vendor and CPU type, BIOS microcode size etc.

       #4 The atomic bringup does the microcode update. This has been
          measured to take up to ~8ms on the primary threads depending
          on the microcode patch size to apply.

     On a two socket SKL server with 56 cores (112 threads) the boot CPU
     spends on current mainline about 800ms busy waiting for the APs to
     come up and apply microcode. That's more than 80% of the actual
     onlining procedure.

     This can be reduced significantly by splitting the bringup
     mechanism into two parts:

       1) Run the prepare callbacks and kick the AP alive for each AP
          which needs to be brought up.

          The APs wake up, do their firmware initialization and run the
          low level kernel startup code including microcode loading in
          parallel up to the first synchronization point. (#1 and #2
          above)

       2) Run the rest of the bringup code strictly serialized per CPU
          (#3 - #5 above) as it's done today.

          Parallelizing that stage of the CPU bringup might be possible
          in theory, but it's questionable whether required surgery
          would be justified for a pretty small gain.

     If the system is large enough the first AP is already waiting at
     the first synchronization point when the boot CPU finished the
     wake-up of the last AP. That reduces the AP bringup time on that
     SKL from ~800ms to ~80ms, i.e. by a factor ~10x.

     The actual gain varies wildly depending on the system, CPU,
     microcode patch size and other factors. There are some
     opportunities to reduce the overhead further, but that needs some
     deep surgery in the x86 CPU bringup code.

     For now this is only enabled on x86, but the core functionality
     obviously works for all SMP capable architectures.

   - Enhancements for SMP function call tracing so it is possible to
     locate the scheduling and the actual execution points. That allows
     to measure IPI delivery time precisely"

7cffdbe360 Updates for the x86 boot process:
- Initialize FPU late.
 
    Right now FPU is initialized very early during boot. There is no real
    requirement to do so. The only requirement is to have it done before
    alternatives are patched.
 
    That's done in check_bugs() which does way more than what the function
    name suggests.
 
    So first rename check_bugs() to arch_cpu_finalize_init() which makes it
    clear what this is about.
 
    Move the invocation of arch_cpu_finalize_init() earlier in
    start_kernel() as it has to be done before fork_init() which needs to
    know the FPU register buffer size.
 
    With those prerequisites the FPU initialization can be moved into
    arch_cpu_finalize_init(), which removes it from the early and fragile
    part of the x86 bringup.
