c8be542408 Modules changes for 6.16-rc1 
- Make .static_call_sites in modules read-only after init
 
   The .static_call_sites sections in modules have been made read-only after
   init to avoid any (non-)accidental modifications, similarly to how they
   are read-only after init in vmlinux.
 
 - The rest are minor cleanups.
 
 The changes have been on linux-next for 2 months, with the exception of the
 last comment-only cleanup.
 
 As discussed previously, we rotate module maintainership among its
 co-maintainers every 6 months. Daniel Gomez is next in line and he will
 send the next pull request for the modules.

Pull fuse updates from Miklos Szeredi:

 - Remove tmp page copying in writeback path (Joanne).

   This removes ~300 lines and with that a lot of complexity related to
   avoiding reclaim related deadlock. The old mechanism is replaced with
   a mapping flag that tells the MM not to block reclaim waiting for
   writeback to complete. The MM parts have been reviewed/acked by
   respective maintainers.

 - Convert more code to handle large folios (Joanne). This still just
   adds the code to deal with large folios and does not enable them yet.

 - Allow invalidating all cached lookups atomically (Luis Henriques).
   This feature is useful for CernVMFS, which currently does this
   iteratively.

 - Align write prefaulting in fuse with generic one (Dave Hansen)

 - Fix race causing invalid data to be cached when setting attributes on
   different nodes of a distributed fs (Guang Yuan Wu)

 - Update documentation for passthrough (Chen Linxuan)

 - Add fdinfo about the device number associated with an opened
   /dev/fuse instance (Chen Linxuan)

 - Increase readdir buffer size (Miklos). This depends on a patch to VFS
   readdir code that was already merged through Christians tree.

* Clean up locking of all vCPUs for a VM by using the *_nest_lock()
   family of functions, and move duplicated code to virt/kvm/.
   kernel/ patches acked by Peter Zijlstra.
 
 * Add MGLRU support to the access tracking perf test.
 
 ARM fixes:
 
 * Make the irqbypass hooks resilient to changes in the GSI<->MSI
   routing, avoiding behind stale vLPI mappings being left behind. The
   fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
   and nuking the vLPI mapping upon a routing change.
 
 * Close another VGIC race where vCPU creation races with VGIC
   creation, leading to in-flight vCPUs entering the kernel w/o private
   IRQs allocated.
 
 * Fix a build issue triggered by the recently added workaround for
   Ampere's AC04_CPU_23 erratum.
 
 * Correctly sign-extend the VA when emulating a TLBI instruction
   potentially targeting a VNCR mapping.
 
 * Avoid dereferencing a NULL pointer in the VGIC debug code, which can
   happen if the device doesn't have any mapping yet.

   fix a race between AP destroy and VMRUN.
 
 * Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for the VM.
 
 * Refine and harden handling of spurious faults.
 
 * Add support for ALLOWED_SEV_FEATURES.
 
 * Add #VMGEXIT to the set of handlers special cased for CONFIG_RETPOLINE=y.
 
 * Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing features
   that utilize those bits.
 
 * Don't account temporary allocations in sev_send_update_data().
 
 * Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock Threshold.
 
 * Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU IBPB, between

Pull more kvm updates from Paolo Bonzini:
  Generic:

   - Clean up locking of all vCPUs for a VM by using the *_nest_lock()
     family of functions, and move duplicated code to virt/kvm/. kernel/
     patches acked by Peter Zijlstra

   - Add MGLRU support to the access tracking perf test

  ARM fixes:

   - Make the irqbypass hooks resilient to changes in the GSI<->MSI
     routing, avoiding behind stale vLPI mappings being left behind. The
     fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
     and nuking the vLPI mapping upon a routing change

   - Close another VGIC race where vCPU creation races with VGIC
     creation, leading to in-flight vCPUs entering the kernel w/o
     private IRQs allocated

   - Fix a build issue triggered by the recently added workaround for
     Ampere's AC04_CPU_23 erratum

   - Correctly sign-extend the VA when emulating a TLBI instruction
     potentially targeting a VNCR mapping

   - Avoid dereferencing a NULL pointer in the VGIC debug code, which
     can happen if the device doesn't have any mapping yet

  s390:

   - Fix interaction between some filesystems and Secure Execution

   - Some cleanups and refactorings, preparing for an upcoming big
     series

  x86:

   - Wait for target vCPU to ack KVM_REQ_UPDATE_PROTECTED_GUEST_STATE
     to fix a race between AP destroy and VMRUN

   - Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for
     the VM

   - Refine and harden handling of spurious faults

   - Add support for ALLOWED_SEV_FEATURES

   - Add #VMGEXIT to the set of handlers special cased for
     CONFIG_RETPOLINE=y

   - Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing
     features that utilize those bits

   - Don't account temporary allocations in sev_send_update_data()

   - Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock
     Threshold

   - Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU
     IBPB, between SVM and VMX

   - Advertise support to userspace for WRMSRNS and PREFETCHI

   - Rescan I/O APIC routes after handling EOI that needed to be
     intercepted due to the old/previous routing, but not the
     new/current routing

   - Add a module param to control and enumerate support for device
     posted interrupts

4c3b7df784 A big core MTD change is the introduction of a new class to always 
register a master device. This is a problem that has been there forever:
 the "master" device was not always present depending on a number of
 heuristics such as the presence of fixed partitions and the absence of a
 Kconfig symbol to force its presence. This was a problem for runtime PM
 operations which might not have the "master" device available in all
 situation.
 
 The SPI NAND subsystem has seen the introduction of DTR operations (the
 equivalent of DDR transfers), which involved quite a few preparation
 patches for clarifying macro names.
 
 In the raw NAND subsystem, the brcmnand driver has been "fixed" for old
 legacy SoCs with an update of the ->exec_op() hook, there has been the
 introduction of a new controller driver named Loongson-1, and the
 Qualcomm driver has received quite a few misc fixes as well as a new
 compatible.
 
 Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP
 table fixups for Macronix MX25L3255E have been merged.
 
 Aside from this, there is the usual load of misc improvement, fixes,
 and yaml conversion.

aa70292325 The SPI NAND subsystem has seen the introduction of DTR operations (the 
equivalent of DDR transfers), which involved quite a few preparation
 patches for clarifying macro names.
 
 In the raw NAND subsystem, the brcmnand driver has been "fixed" for old
 legacy SoCs with an update of the ->exec_op() hook, there has been the
 introduction of a new controller driver named Loongson-1, and the
 Qualcomm driver has received quite a few misc fixes as well as a new
 compatible.
 
 Aside from this, there is the usual load of misc improvement and fixes.

61374cc145 KVM/arm64 fixes for 6.16, take #1 
- Make the irqbypass hooks resilient to changes in the GSI<->MSI
   routing, avoiding behind stale vLPI mappings being left behind. The
   fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
   and nuking the vLPI mapping upon a routing change.
 
 - Close another VGIC race where vCPU creation races with VGIC
   creation, leading to in-flight vCPUs entering the kernel w/o private
   IRQs allocated.
 
 - Fix a build issue triggered by the recently added workaround for
   Ampere's AC04_CPU_23 erratum.
 
 - Correctly sign-extend the VA when emulating a TLBI instruction
   potentially targeting a VNCR mapping.
 
 - Avoid dereferencing a NULL pointer in the VGIC debug code, which can
   happen if the device doesn't have any mapping yet.

438e22801b rtmutex_api: provide correct extern functions 
Commit fb49f07ba1 ("locking/mutex: implement mutex_lock_killable_nest_lock")
changed the set of functions that mutex.c defines when CONFIG_DEBUG_LOCK_ALLOC
is set.

- it removed the "extern" declaration of mutex_lock_killable_nested from
  include/linux/mutex.h, and replaced it with a macro since it could be
  treated as a special case of _mutex_lock_killable.  It also removed a
  definition of the function in kernel/locking/mutex.c.

- likewise, it replaced mutex_trylock() with the more generic
  mutex_trylock_nest_lock() and replaced mutex_trylock() with a macro.

However, it left the old definitions in place in kernel/locking/rtmutex_api.c,
which causes failures when building with CONFIG_RT_MUTEXES=y.  Bring over
the changes.

5c78e793f7 overflow: Introduce __DEFINE_FLEX for having no initializer 
While not yet in the tree, there is a proposed patch[1] that was
depending on the prior behavior of _DEFINE_FLEX, which did not have an
explicit initializer. Provide this via __DEFINE_FLEX now, which can also
have attributes applied (e.g. __uninitialized).

Examples of the resulting initializer behaviors can be seen here:

When executing "modprobe iTCO_wdt heartbeat=700", the user-specified
'heartbeat' parameter exceeds the valid range, the driver clamps the
timeout to default 30s but fails to update the logged 'heartbeat' value,
resulting in misleading log output:

iTCO_wdt iTCO_wdt: timeout value out of range, using 30
iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0)

After validating the range, update the 'heartbeat' value with the clamped
timeout value to ensure that log messages accurately reflect the actual
runtime parameters.

535d1784d8 watchdog: Add driver for Intel OC WDT 
Add a driver for the Intel Over-Clocking Watchdog found in Intel
Platform Controller (PCH) chipsets. This watchdog is controlled
via a simple single-register interface and would otherwise be
standard except for the presence of a LOCK bit that can only be
set once per power cycle, needing extra handling around it.

cc0df5eba1 watchdog: arm_smc_wdt: get wdt status through SMCWD_GET_TIMELEFT 
The optional SMCWD_GET_TIMELEFT command can be used to detect if
the watchdog has already been started.
See the implementation in OP-TEE secure OS [1].

At probe time, check if the watchdog is already started and then
set WDOG_HW_RUNNING in the watchdog status. This will cause the
watchdog framework to ping the watchdog until a userspace watchdog
daemon takes over the control.
