dd7fe5d9fd rtc: max31335: Fix comparison in max31335_volatile_reg() 
Clang warns (or errors with CONFIG_WERROR=y):

    drivers/rtc/rtc-max31335.c:211:36: error: use of logical '||' with constant operand [-Werror,-Wconstant-logical-operand]

This clearly should be a comparison against reg. Fix the comparison so
that max31335_volatile_reg() does not always return true.

ed6c23b175 This is the main pin control pull request for the v6.8 kernel series. 
Core changes:
 
 - A new PINCTRL_GROUP_DESC() infrastructure macro is added and
   used in different drivers, generic group description struct
   group_desc is now used all over the place.
 
 New drivers:
 
 - New driver for the Texas Instruments TPS6494 Power Management IC.
 
 - New driver for the Lantic PEF2256 framer pin multiplexer.
   This IC has some pins that can be reconfigured in different
   ways. The actual driver comes on an immutable branch with the
   net WAN parts, the IC is some latest-and-greatest serial line
   funnel for e.g. wireless access points.
 
 - New subdriver for the Samsung Exynos Auto V920 pin controller,
   used for automotive applications.
 
 - New subdriver for the Samsung "GS101" SoC pin controller, this
   is the Google "Tensor" SoC used in the Google Pixel 6.
 
 - New subdriver for the Intel Meteor Point SoC pin controller.
 
 - New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS pin
   controllers.
 
 - New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
   controller.
 
 - New subdriver for the Qualcomm SM4450 top level (TLMM) pin
   controller.
 
 - The "single" pin controller now supports the Texas Instruments
   J7200 SoC.
 
 Improvements:
 
 - Intel has created a new (Intel-)generic pin controller driver that
   is now used by all contemporary Intel platforms.
 
 - Intel is now also making use of some cleanup helpers.
 
 - Enble 910 Ohm bias in the Intel Tangier driver.
 
 - The Samsung driver now suppors irq_set_affinity() in it's IRQ chip
   giving support for non wake up external gpio interrupts.

Merge tag 'pinctrl-v6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "For this kernel cycle I managed an immutable branch for the PEF2256
  WAN framer that has some pin control portions. It already landed in
  your tree through the net pull request but here it is mentioned again.

  The most interesting is perhaps the Samsung Exynos subdrivers for the
  Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for
  automotive. Along with the earlier merged Tesla FSD subdriver it shows
  some of the versatile uses of the Samsung Exynos silicon. It is also
  used in the latest version of Axis Communications ARTPEC chips so it
  is a very widely deployed SoC family.

  We also have the Intel Meteor Lake SoC which I think is for laptops.
  It's a pretty interesting chip with Xe graphics and integrated PCH.

  Core changes:

   - A new PINCTRL_GROUP_DESC() infrastructure macro is added and used
     in different drivers, generic group description struct group_desc
     is now used all over the place.

09d1c6a80f Generic: 
- Use memdup_array_user() to harden against overflow.
 
 - Unconditionally advertise KVM_CAP_DEVICE_CTRL for all architectures.
 
 - Clean up Kconfigs that all KVM architectures were selecting
 
 - New functionality around "guest_memfd", a new userspace API that
   creates an anonymous file and returns a file descriptor that refers
   to it.  guest_memfd files are bound to their owning virtual machine,
   cannot be mapped, read, or written by userspace, and cannot be resized.
   guest_memfd files do however support PUNCH_HOLE, which can be used to
   switch a memory area between guest_memfd and regular anonymous memory.
 
 - New ioctl KVM_SET_MEMORY_ATTRIBUTES allowing userspace to specify
   per-page attributes for a given page of guest memory; right now the
   only attribute is whether the guest expects to access memory via
   guest_memfd or not, which in Confidential SVMs backed by SEV-SNP,
   TDX or ARM64 pKVM is checked by firmware or hypervisor that guarantees
   confidentiality (AMD PSP, Intel TDX module, or EL2 in the case of pKVM).
 
 x86:
 
 - Support for "software-protected VMs" that can use the new guest_memfd
   and page attributes infrastructure.  This is mostly useful for testing,
   since there is no pKVM-like infrastructure to provide a meaningfully
   reduced TCB.
 
 - Fix a relatively benign off-by-one error when splitting huge pages during
   CLEAR_DIRTY_LOG.
 
 - Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf
   TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE.
 
 - Use more generic lockdep assertions in paths that don't actually care
   about whether the caller is a reader or a writer.
 
 - let Xen guests opt out of having PV clock reported as "based on a stable TSC",
   because some of them don't expect the "TSC stable" bit (added to the pvclock
   ABI by KVM, but never set by Xen) to be set.
 
 - Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL.
 
 - Advertise flush-by-ASID support for nSVM unconditionally, as KVM always
   flushes on nested transitions, i.e. always satisfies flush requests.  This
   allows running bleeding edge versions of VMware Workstation on top of KVM.
 
 - Sanity check that the CPU supports flush-by-ASID when enabling SEV support.
 
 - On AMD machines with vNMI, always rely on hardware instead of intercepting
   IRET in some cases to detect unmasking of NMIs
 
 - Support for virtualizing Linear Address Masking (LAM)
 
 - Fix a variety of vPMU bugs where KVM fail to stop/reset counters and other state
   prior to refreshing the vPMU model.
 
 - Fix a double-overflow PMU bug by tracking emulated counter events using a
   dedicated field instead of snapshotting the "previous" counter.  If the
   hardware PMC count triggers overflow that is recognized in the same VM-Exit
   that KVM manually bumps an event count, KVM would pend PMIs for both the
   hardware-triggered overflow and for KVM-triggered overflow.
 
 - Turn off KVM_WERROR by default for all configs so that it's not
   inadvertantly enabled by non-KVM developers, which can be problematic for
   subsystems that require no regressions for W=1 builds.
 
 - Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL
   "features".
 
 - Don't force a masterclock update when a vCPU synchronizes to the current TSC
   generation, as updating the masterclock can cause kvmclock's time to "jump"
   unexpectedly, e.g. when userspace hotplugs a pre-created vCPU.
 
 - Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths,
   partly as a super minor optimization, but mostly to make KVM play nice with
   position independent executable builds.
 
 - Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on
   CONFIG_HYPERV as a minor optimization, and to self-document the code.
 
 - Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV "emulation"
   at build time.
 
 ARM64:
 
 - LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB
   base granule sizes. Branch shared with the arm64 tree.
 
 - Large Fine-Grained Trap rework, bringing some sanity to the
   feature, although there is more to come. This comes with
   a prefix branch shared with the arm64 tree.
 
 - Some additional Nested Virtualization groundwork, mostly
   introducing the NV2 VNCR support and retargetting the NV
   support to that version of the architecture.
 
 - A small set of vgic fixes and associated cleanups.
 
 Loongarch:
 
 - Optimization for memslot hugepage checking
 
 - Cleanup and fix some HW/SW timer issues
 
 - Add LSX/LASX (128bit/256bit SIMD) support
 
 RISC-V:
 
 - KVM_GET_REG_LIST improvement for vector registers
 
 - Generate ISA extension reg_list using macros in get-reg-list selftest
 
 - Support for reporting steal time along with selftest
 
 s390:
 
 - Bugfixes
 
 Selftests:
 
 - Fix an annoying goof where the NX hugepage test prints out garbage
   instead of the magic token needed to run the test.
 
 - Fix build errors when a header is delete/moved due to a missing flag
   in the Makefile.
 
 - Detect if KVM bugged/killed a selftest's VM and print out a helpful
   message instead of complaining that a random ioctl() failed.
 
 - Annotate the guest printf/assert helpers with __printf(), and fix the
   various bugs that were lurking due to lack of said annotation.
 
 There are two non-KVM patches buried in the middle of guest_memfd support:
 
   fs: Rename anon_inode_getfile_secure() and anon_inode_getfd_secure()
   mm: Add AS_UNMOVABLE to mark mapping as completely unmovable
 
 The first is small and mostly suggested-by Christian Brauner; the second
 a bit less so but it was written by an mm person (Vlastimil Babka).

Pull vfs fixes from Christian Brauner:
 "This contains two fixes for the current merge window. The listmount
  changes that you requested and a fix for a fsnotify performance
  regression:

   - The proposed listmount changes are currently under my authorship. I
     wasn't sure whether you'd wanted to be author as the patch wasn't
     signed off. If you do I'm happy if you just apply your own patch.

     I've tested the patch with my sh4 cross-build setup. And confirmed
     that a) the build failure with sh on current upstream is
     reproducible and that b) the proposed patch fixes the build
     failure. That should only leave the task of fixing put_user on sh.

   - The fsnotify regression was caused by moving one of the hooks out
     of the security hook in preparation for other fsnotify work. This
     meant that CONFIG_SECURITY would have compiled out the fsnotify
     hook before but didn't do so now.

     That lead to up to 6% performance regression in some io_uring
     workloads that compile all fsnotify and security checks out. Fix
     this by making sure that the relevant hooks are covered by the
     already existing CONFIG_FANOTIFY_ACCESS_PERMISSIONS where the
     relevant hook belongs"

26db46bc9c drm/bridge: parade-ps8640: Ensure bridge is suspended in .post_disable() 
The ps8640 bridge seems to expect everything to be power cycled at the
disable process, but sometimes ps8640_aux_transfer() holds the runtime
PM reference and prevents the bridge from suspend.

Prevent that by introducing a mutex lock between ps8640_aux_transfer()
and .post_disable() to make sure the bridge is really powered off.

4f41d30cd6 kdb: Fix a potential buffer overflow in kdb_local() 
When appending "[defcmd]" to 'kdb_prompt_str', the size of the string
already in the buffer should be taken into account.

An option could be to switch from strncat() to strlcat() which does the
correct test to avoid such an overflow.

However, this actually looks as dead code, because 'defcmd_in_progress'
can't be true here.
See a more detailed explanation at [1].

b4bc35cf87 io_uring: combine cq_wait_nr checks 
Instead of explicitly checking ->cq_wait_nr for whether there are
waiting, which is currently represented by 0, we can store there a
large value and the nr_tw will automatically filter out those cases.
Add a named constant for that and for the wake up bias value.

e8c407717b io_uring: clean *local_work_add var naming

While it reads as do something if it's not the first entry, it does
exactly the opposite because "first" here is a pointer to the first
entry. Remove the confusion by renaming it into "head".

dc12d1799c io_uring: adjust defer tw counting 
The UINT_MAX work item counting bias in io_req_local_work_add() in case
of !IOU_F_TWQ_LAZY_WAKE works in a sense that we will not miss a wake up,
however it's still eerie. In particular, if we add a lazy work item
after a non-lazy one, we'll increment it and get nr_tw==0, and
subsequent adds may try to unnecessarily wake up the task, which is
though not so likely to happen in real workloads.

Half the bias, it's still large enough to be larger than any valid
->cq_wait_nr, which is limited by IORING_MAX_CQ_ENTRIES, but further
have a good enough of space before it overflows.

-Wstringop-overflow is broken on GCC11. In future changes it will
be moved to the normal C flags in the top level Makefile (out of
Makefile.extrawarn), but accounting for the compiler support.

Just remove it out of i915's forced extra warnings, preparing for the
upcoming change and avoiding build warnings to show up.
