When a static_key is marked ro_after_init, its state will never change
(after init), therefore jump_label_update() will never need to iterate
the entries, and thus module load won't actually need to track this --
avoiding the static_key::next write.

Therefore, mark these keys such that jump_label_add_module() might
recognise them and avoid the modification.

Use the special state: 'static_key_linked(key) && !static_key_mod(key)'
to denote such keys.

jump_label_add_module() does not exist under CONFIG_JUMP_LABEL=n, so the
newly-introduced jump_label_init_ro() can be defined as a nop for that
configuration.

The 'inc' parameter of lockevent_add() and the cond parameter of
lockevent_cond_inc() are only evaluated when CONFIG_LOCK_EVENT_COUNTS
is on. That can cause problem if those parameters are expressions
with side effect like a "++". Fix this by evaluating those non-event
parameters once even if CONFIG_LOCK_EVENT_COUNTS is off. This will also
eliminate the need of the __maybe_unused attribute to the wait_early
local variable in pv_wait_node().

This reverts commit 1601cd53.

This fix is applied globally to all devices, and it may change the
existing control names.  When the devices are managed with the fixed
configuration like UCM, such control name mismatch may lead to
significant regressions.

For avoiding that kind of regression, we would need to apply such
changes conditionally, but it'd take time to settle down.
While the original fix is a good thing in general, in order to address
the regression, let's revert the change for now.

When a CPU enters into idle and deactivates itself from the timer
migration hierarchy without any global timer of its own to propagate,
the group event of that CPU is set to "ignore" and tmigr_update_events()
accordingly performs an early return without considering timers queued
by other CPUs.

If the hierarchy has a single level, and the CPU is the last one to
enter idle, it will ignore others' global timers, as in the following
layout:

           [GRP0:0]
         migrator = 0
         active   = 0
         nextevt  = T0i
          /         \
         0           1
      active (T0i)  idle (T1)

0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.

           [GRP0:0]
         migrator = NONE
         active   = NONE
         nextevt  = T0i
          /         \
         0           1
      idle (T0i)  idle (T1)

1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1 and CPU 0 goes to idle with T1
unhandled.

This isn't proper to single level hierarchy though. A similar issue,
although slightly different, may arise on multi-level:

                            [GRP1:0]
                         migrator = GRP0:0
                         active   = GRP0:0
                         nextevt  = T0:0i, T0:1
                         /              \
              [GRP0:0]                  [GRP0:1]
           migrator = 0              migrator = NONE
           active   = 0              active   = NONE
           nextevt  = T0i            nextevt  = T2
           /         \                /         \
          0 (T0i)     1 (T1)         2 (T2)      3
      active         idle            idle       idle

0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
CPU 2 also has a timer. The expiry order is T0 (ignored) < T1 < T2

                            [GRP1:0]
                         migrator = GRP0:0
                         active   = GRP0:0
                         nextevt  = T0:0i, T0:1
                         /              \
              [GRP0:0]                  [GRP0:1]
           migrator = NONE           migrator = NONE
           active   = NONE           active   = NONE
           nextevt  = T0i            nextevt  = T2
           /         \                /         \
          0 (T0i)     1 (T1)         2 (T2)      3
        idle         idle            idle         idle

1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1. The change only propagated up to 1st
level so far.

                            [GRP1:0]
                         migrator = NONE
                         active   = NONE
                         nextevt  = T0:1
                         /              \
              [GRP0:0]                  [GRP0:1]
           migrator = NONE           migrator = NONE
           active   = NONE           active   = NONE
           nextevt  = T0i            nextevt  = T2
           /         \                /         \
          0 (T0i)     1 (T1)         2 (T2)      3
        idle         idle            idle         idle

2) The change now propagates up to the top. tmigr_update_events() finds
that the child event is ignored and thus removes it. The top level next
event is now T2 which is returned to CPU 0 as its next effective expiry
to take account for as the global idle migrator. However T1 has been
ignored along the way, leaving it unhandled.

Fix those issues with removing the buggy related early return. Ignored
child events must not prevent from evaluating the other events within
the same group.

 "Small changes to string processing in device attribute"

* tag 'firewire-updates-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394:
  firewire: core: fix build failure due to the caller of fw_csr_string()

Pull CXL updates from Dan Williams:
 "CXL has mechanisms to enumerate the performance characteristics of
  memory devices. Those mechanisms allow Linux to build the equivalent
  of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
  capability is necessary because static ACPI can not represent dynamic
  CXL configurations (and reconfigurations).

  So, building on the v6.8 work to add "Quality of Service" enumeration,
  this update plumbs CXL "access coordinates" (read/write access latency
  and bandwidth) in all the same places that ACPI HMAT feeds similar
  data. Follow-on patches from the -mm side can then use that data to
  feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
  drivers/base/.

  The other feature update this cycle is support for CXL error injection
  via the ACPI EINJ module. That facility enables injection of bus
  protocol errors provided the user knows the magic address values to
  insert in the interface. To hide that magic, and make this easier to
  use, new error injection attributes were added to CXL debugfs. That
  interface injects the errors relative to a CXL object rather than
  require user tooling to know how to lookup and inject RCRB (Root
  Complex Register Block) addresses into the raw EINJ debugfs interface.
  It received some helpful review comments from Tony, but no explicit
  acks from the ACPI side. The primary user visible change for existing
  EINJ users is that they may find that einj.ko was already loaded by
  cxl_core.ko. Previously, einj.ko was only loaded on demand.

  The usual collection of miscellaneous cleanups are also present this
  cycle.

  Summary:

   - Supplement ACPI HMAT reported memory performance with native CXL
     memory performance enumeration

   - Add support for CXL error injection via the ACPI EINJ mechanism

   - Cleanup CXL DOE and CDAT integration

   - Miscellaneous cleanups and fixes"

This is clear from the stack trace, we call nfs4_ff_layout_prepare_ds()
which could error out initializing the mirror_ds, and then we go to
clean it all up and our check is only for if (!mirror->mirror_ds).  This
is inconsistent with the rest of the users of mirror_ds, which have

  if (IS_ERR_OR_NULL(mirror_ds))

to keep from tripping over this exact scenario.  Fix this up in
ff_layout_cancel_io() to make sure we don't panic when we get an error.
I also spot checked all the other instances of checking mirror_ds and we
appear to be doing the correct checks everywhere, only unconditionally
dereferencing mirror_ds when we know it would be valid.

This reverts commits 99101dda and
b80b701d.

Linus reports that the sysreg reserved bit checks in KVM have led to
build failures, arising from commit fdd867fe ("arm64/sysreg: Add
register fields for ID_AA64DFR1_EL1") giving meaning to fields that were
previously RES0.

Of course, this is a genuine issue, since KVM's sysreg emulation depends
heavily on the definition of reserved fields. But at this point the
build breakage is far more offensive, and the right course of action is
to revert and retry later.

All of these build-time assertions were on by default before
commit 99101dda ("KVM: arm64: Make build-time check of RES0/RES1
bits optional"), so deliberately revert it all atomically to avoid
introducing further breakage of bisection.

Pull VFIO updates from Alex Williamson:

 - Add warning in unlikely case that device is not captured with
   driver_override (Kunwu Chan)

 - Error handling improvements in mlx5-vfio-pci to detect firmware
   tracking object error states, logging of firmware error syndrom, and
   releasing of firmware resources in aborted migration sequence (Yishai
   Hadas)

 - Correct an un-alphabetized VFIO MAINTAINERS entry (Alex Williamson)

 - Make the mdev_bus_type const and also make the class struct const for
   a couple of the vfio-mdev sample drivers (Ricardo B. Marliere)

 - Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
   Grace-Hopper superchip. During initialization of the chip-to-chip
   interconnect in this hardware module, the PCI BARs of the device
   become unused in favor of a faster, coherent mechanism for exposing
   device memory. This driver primarily changes the VFIO representation
   of the device to masquerade this coherent aperture to replace the
   physical PCI BARs for userspace drivers. This also incorporates use
   of a new vma flag allowing KVM to use write combining attributes for
   uncached device memory (Ankit Agrawal)

 - Reset fixes and cleanups for the pds-vfio-pci driver. Save and
   restore files were previously leaked if the device didn't pass
   through an error state, this is resolved and later re-fixed to
   prevent access to the now freed files. Reset handling is also
   refactored to remove the complicated deferred reset mechanism (Brett
   Creeley)

 - Remove some references to pl330 in the vfio-platform amba driver
   (Geert Uytterhoeven)

 - Remove twice redundant and ugly code to unpin incidental pins of the
   zero-page (Alex Williamson)

 - Deferred reset logic is also removed from the hisi-acc-vfio-pci
   driver as a simplification (Shameer Kolothum)

 - Enforce that mlx5-vfio-pci devices must support PRE_COPY and remove
   resulting unnecessary code. There is no device firmware that has been
   available publicly without this support (Yishai Hadas)

 - Switch over to using the .remove_new callback for vfio-platform in
   support of the broader transition for a void remove function (Uwe
   Kleine-König)

 - Resolve multiple issues in interrupt code for VFIO bus drivers that
   allow calling eventfd_signal() on a NULL context. This also remove a
   potential race in INTx setup on certain hardware for vfio-pci, races
   with various mechanisms to mask INTx, and leaked virqfds in
   vfio-platform (Alex Williamson)

Pull kvm updates from Paolo Bonzini:
 "S390:

   - Changes to FPU handling came in via the main s390 pull request

   - Only deliver to the guest the SCLP events that userspace has
     requested

   - More virtual vs physical address fixes (only a cleanup since
     virtual and physical address spaces are currently the same)

   - Fix selftests undefined behavior

  x86:

   - Fix a restriction that the guest can't program a PMU event whose
     encoding matches an architectural event that isn't included in the
     guest CPUID. The enumeration of an architectural event only says
     that if a CPU supports an architectural event, then the event can
     be programmed *using the architectural encoding*. The enumeration
     does NOT say anything about the encoding when the CPU doesn't
     report support the event *in general*. It might support it, and it
     might support it using the same encoding that made it into the
     architectural PMU spec

   - Fix a variety of bugs in KVM's emulation of RDPMC (more details on
     individual commits) and add a selftest to verify KVM correctly
     emulates RDMPC, counter availability, and a variety of other
     PMC-related behaviors that depend on guest CPUID and therefore are
     easier to validate with selftests than with custom guests (aka
     kvm-unit-tests)

   - Zero out PMU state on AMD if the virtual PMU is disabled, it does
     not cause any bug but it wastes time in various cases where KVM
     would check if a PMC event needs to be synthesized

   - Optimize triggering of emulated events, with a nice ~10%
     performance improvement in VM-Exit microbenchmarks when a vPMU is
     exposed to the guest

   - Tighten the check for "PMI in guest" to reduce false positives if
     an NMI arrives in the host while KVM is handling an IRQ VM-Exit

   - Fix a bug where KVM would report stale/bogus exit qualification
     information when exiting to userspace with an internal error exit
     code

   - Add a VMX flag in /proc/cpuinfo to report 5-level EPT support

   - Rework TDP MMU root unload, free, and alloc to run with mmu_lock
     held for read, e.g. to avoid serializing vCPUs when userspace
     deletes a memslot

   - Tear down TDP MMU page tables at 4KiB granularity (used to be
     1GiB). KVM doesn't support yielding in the middle of processing a
     zap, and 1GiB granularity resulted in multi-millisecond lags that
     are quite impolite for CONFIG_PREEMPT kernels

   - Allocate write-tracking metadata on-demand to avoid the memory
     overhead when a kernel is built with i915 virtualization support
     but the workloads use neither shadow paging nor i915 virtualization

   - Explicitly initialize a variety of on-stack variables in the
     emulator that triggered KMSAN false positives

   - Fix the debugregs ABI for 32-bit KVM

   - Rework the "force immediate exit" code so that vendor code
     ultimately decides how and when to force the exit, which allowed
     some optimization for both Intel and AMD

   - Fix a long-standing bug where kvm_has_noapic_vcpu could be left
     elevated if vCPU creation ultimately failed, causing extra
     unnecessary work

   - Cleanup the logic for checking if the currently loaded vCPU is
     in-kernel

   - Harden against underflowing the active mmu_notifier invalidation
     count, so that "bad" invalidations (usually due to bugs elsehwere
     in the kernel) are detected earlier and are less likely to hang the
     kernel

  x86 Xen emulation:

   - Overlay pages can now be cached based on host virtual address,
     instead of guest physical addresses. This removes the need to
     reconfigure and invalidate the cache if the guest changes the gpa
     but the underlying host virtual address remains the same

   - When possible, use a single host TSC value when computing the
     deadline for Xen timers in order to improve the accuracy of the
     timer emulation

   - Inject pending upcall events when the vCPU software-enables its
     APIC to fix a bug where an upcall can be lost (and to follow Xen's
     behavior)

   - Fall back to the slow path instead of warning if "fast" IRQ
     delivery of Xen events fails, e.g. if the guest has aliased xAPIC
     IDs

  RISC-V:

   - Support exception and interrupt handling in selftests

   - New self test for RISC-V architectural timer (Sstc extension)

   - New extension support (Ztso, Zacas)

   - Support userspace emulation of random number seed CSRs

  ARM:

   - Infrastructure for building KVM's trap configuration based on the
     architectural features (or lack thereof) advertised in the VM's ID
     registers

   - Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
     x86's WC) at stage-2, improving the performance of interacting with
     assigned devices that can tolerate it

   - Conversion of KVM's representation of LPIs to an xarray, utilized
     to address serialization some of the serialization on the LPI
     injection path

   - Support for _architectural_ VHE-only systems, advertised through
     the absence of FEAT_E2H0 in the CPU's ID register

   - Miscellaneous cleanups, fixes, and spelling corrections to KVM and
     selftests

  LoongArch:

   - Set reserved bits as zero in CPUCFG

   - Start SW timer only when vcpu is blocking

   - Do not restart SW timer when it is expired

   - Remove unnecessary CSR register saving during enter guest

   - Misc cleanups and fixes as usual

  Generic:

   - Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically
     always true on all architectures except MIPS (where Kconfig
     determines the available depending on CPU capabilities). It is
     replaced either by an architecture-dependent symbol for MIPS, and
     IS_ENABLED(CONFIG_KVM) everywhere else

   - Factor common "select" statements in common code instead of
     requiring each architecture to specify it

   - Remove thoroughly obsolete APIs from the uapi headers

   - Move architecture-dependent stuff to uapi/asm/kvm.h

   - Always flush the async page fault workqueue when a work item is
     being removed, especially during vCPU destruction, to ensure that
     there are no workers running in KVM code when all references to
     KVM-the-module are gone, i.e. to prevent a very unlikely
     use-after-free if kvm.ko is unloaded

   - Grab a reference to the VM's mm_struct in the async #PF worker
     itself instead of gifting the worker a reference, so that there's
     no need to remember to *conditionally* clean up after the worker

  Selftests:

   - Reduce boilerplate especially when utilize selftest TAP
     infrastructure

   - Add basic smoke tests for SEV and SEV-ES, along with a pile of
     library support for handling private/encrypted/protected memory

   - Fix benign bugs where tests neglect to close() guest_memfd files"

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add cleanup.h based auto release of struct device_node pointers via
     __free marking and new for_each_child_of_node_scoped() iterator to
     use it.

   - Always create a base skeleton DT when CONFIG_OF is enabled. This
     supports several usecases of adding DT data on non-DT booted
     systems.

   - Move around some /reserved-memory code in preparation for further
     improvements

   - Add a stub for_each_property_of_node() for !OF

   - Adjust the printk levels on some messages

   - Fix __be32 sparse warning

   - Drop RESERVEDMEM_OF_DECLARE usage from Freescale qbman driver
     (currently orphaned)

   - Add Saravana Kannan and drop Frank Rowand as DT maintainers

  DT bindings:

   - Convert Mediatek timer, Mediatek sysirq, fsl,imx6ul-tsc,
     fsl,imx6ul-pinctrl, Atmel AIC, Atmel HLCDC, FPGA region, and
     xlnx,sd-fec to DT schemas

   - Add existing, but undocumented fsl,imx-anatop binding

   - Add bunch of undocumented vendor prefixes used in compatible
     strings

   - Drop obsolete brcm,bcm2835-pm-wdt binding

   - Drop obsolete i2c.txt which as been replaced with schema in
     dtschema

   - Add DPS310 device and sort trivial-devices.yaml

   - Enable undocumented compatible checks on DT binding examples

   - More QCom maintainer fixes/updates

   - Updates to writing-schema.rst and DT submitting-patches.rst to
     cover some frequent review comments

   - Clean-up SPDX tags to use 'OR' rather than 'or'"

Pull MTD updates from Miquel Raynal:
 "MTD:

   - The Carillo Ranch driver has been removed

   - Top level mtd bindings have received a couple of improvements
     (references, selects)

   - The ssfdc driver received few minor adjustments

   - The usual load of misc/small improvements and fixes

  Raw NAND:

   - The main series brought is an update of the Broadcom support to
     support all BCMBCA SoCs and their specificity (ECC, write
     protection, configuration straps), plus a few misc fixes and
     changes in the main driver. Device tree updates are also part of
     this PR, initially because of a misunderstanding on my side.

   - The STM32_FMC2 controller driver is also upgraded to properly
     support MP1 and MP25 SoCs.

   - A new compatible is added for an Atmel flavor.

   - Among all these feature changes, there is as well a load of
     continuous read related fixes, avoiding more corner conditions and
     clarifying the logic. Finally a few miscellaneous fixes are made to
     the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller
     driver, as well as final one in the Hynix vendor driver.

  SPI-NAND:

   - The ESMT support has been extended to match 5 bytes ID to avoid
     collisions. Winbond support on its side receives support for
     W25N04KV chips.

  SPI NOR:

   - SPI NOR gets the non uniform erase code cleaned. We stopped using
     bitmasks for erase types and flags, and instead introduced
     dedicated members. We then passed the SPI NOR erase map to MTD.
     Users can now determine the erase regions and make informed
     decisions on partitions size.

   - An optional interrupt property is now described in the bindings"

Pull i2c updates from Wolfram Sang:
 "Minor changes to the I2C core. Most changes are in drivers:

  The i801 and designware drivers received most of the changes,
  including refactorings and some additions.

  Recovery changes for the iMX and iMX-LPI2C are now utilizing the
  generic i2c support.

  The Cadence driver now supports system suspend and resume.

  The hisi, mpc, sh_mobile, and npcm drivers have undergone some
  cleanups and improvements. Meanwhile, Uwe continues his work on
  converting the "remove" callback to become a void function.

  The pca954x mux driver now supports additional configurations, such as
  isolating faulty channels and flushing stuck buses, among others.

  Support has been added for Renesas r8a779h0, i.MX95 LPI2C, and
  Microchip sam9x7. Meanwhile, Geert lays the groundwork for the
