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"

fs: rework listmount() implementation
Linus pointed out that there's error handling and naming issues in the
that we should rewrite:

* Perform the access checks for the buffer before actually doing any
  work instead of doing it during the iteration.
* Rename the arguments to listmount() and do_listmount() to clarify what
  the arguments are used for.
* Get rid of the pointless ctr variable and overflow checking.
* Get rid of the pointless speculation check.

5d4747a6cc userfaultfd: avoid huge_zero_page in UFFDIO_MOVE
While testing UFFDIO_MOVE ioctl, syzbot triggered VM_BUG_ON_PAGE caused by
a call to PageAnonExclusive() with a huge_zero_page as a parameter. 
UFFDIO_MOVE does not yet handle zeropages and returns EBUSY when one is
encountered.  Add an early huge_zero_page check in the PMD move path to
avoid this situation.

00bcfcd47a selftests: mm: hugepage-vmemmap fails on 64K page size systems
The kernel sefltest mm/hugepage-vmemmap fails on architectures which has
different page size other than 4K.  In hugepage-vmemmap page size used is
4k so the pfn calculation will go wrong on systems which has different
page size .The length of MAP_HUGETLB memory must be hugepage aligned but
in hugepage-vmemmap map length is 2M so this will not get aligned if the
system has differnet hugepage size.

Added  psize() to get the page size and default_huge_page_size() to
get the default hugepage size at run time, hugepage-vmemmap test pass
on powerpc with 64K page size and x86 with 4K page size.

Result on powerpc without patch (page size 64K)
*# ./hugepage-vmemmap
Returned address is 0x7effff000000 whose pfn is 0
Head page flags (100000000) is invalid

1168413414 mm/memory_hotplug: fix memmap_on_memory sysfs value retrieval
set_memmap_mode() stores the kernel parameter memmap mode as an integer. 
However, the get_memmap_mode() function utilizes param_get_bool() to fetch
the value as a boolean, leading to potential endianness issue.  On
Big-endian architectures, the memmap_on_memory is consistently displayed
as 'N' regardless of its actual status.

To address this endianness problem, the solution involves obtaining the
mode as an integer.  This adjustment ensures the proper display of the
memmap_on_memory parameter, presenting it as one of the following options:
Force, Y, or N.

7bb943806f kexec: do syscore_shutdown() in kernel_kexec
syscore_shutdown() runs driver and module callbacks to get the system into
a state where it can be correctly shut down.  In commit 6f389a8f1d ("PM
/ reboot: call syscore_shutdown() after disable_nonboot_cpus()")
syscore_shutdown() was removed from kernel_restart_prepare() and hence got
(incorrectly?) removed from the kexec flow.  This was innocuous until
commit 6735150b69 ("KVM: Use syscore_ops instead of reboot_notifier to
hook restart/shutdown") changed the way that KVM registered its shutdown
callbacks, switching from reboot notifiers to syscore_ops.shutdown.  As
syscore_shutdown() is missing from kexec, KVM's shutdown hook is not run
and virtualisation is left enabled on the boot CPU which results in triple
faults when switching to the new kernel on Intel x86 VT-x with VMXE
enabled.

Fix this by adding syscore_shutdown() to the kexec sequence.  In terms of
where to add it, it is being added after migrating the kexec task to the
boot CPU, but before APs are shut down.  It is not totally clear if this
is the best place: in commit 6f389a8f1d ("PM / reboot: call
syscore_shutdown() after disable_nonboot_cpus()") it is stated that
"syscore_ops operations should be carried with one CPU on-line and
interrupts disabled." APs are only offlined later in machine_shutdown(),
so this syscore_shutdown() is being run while APs are still online.  This
seems to be the correct place as it matches where syscore_shutdown() is
run in the reboot and halt flows - they also run it before APs are shut
down.  The assumption is that the commit message in commit 6f389a8f1d
("PM / reboot: call syscore_shutdown() after disable_nonboot_cpus()") is
no longer valid.

KVM has been discussed here as it is what broke loudly by not having
syscore_shutdown() in kexec, but this change impacts more than just KVM;
all drivers/modules which register a syscore_ops.shutdown callback will
now be invoked in the kexec flow.  Looking at some of them like x86 MCE it
is probably more correct to also shut these down during kexec. 
Maintainers of all drivers which use syscore_ops.shutdown are added on CC
for visibility.  They are:

arch/powerpc/platforms/cell/spu_base.c  .shutdown = spu_shutdown,
arch/x86/kernel/cpu/mce/core.c	        .shutdown = mce_syscore_shutdown,
arch/x86/kernel/i8259.c                 .shutdown = i8259A_shutdown,
drivers/irqchip/irq-i8259.c	        .shutdown = i8259A_shutdown,
drivers/irqchip/irq-sun6i-r.c	        .shutdown = sun6i_r_intc_shutdown,
drivers/leds/trigger/ledtrig-cpu.c	.shutdown = ledtrig_cpu_syscore_shutdown,
drivers/power/reset/sc27xx-poweroff.c	.shutdown = sc27xx_poweroff_shutdown,
kernel/irq/generic-chip.c	        .shutdown = irq_gc_shutdown,
virt/kvm/kvm_main.c	                .shutdown = kvm_shutdown,

This has been tested by doing a kexec on x86_64 and aarch64.

efbd639835 scripts/decode_stacktrace.sh: optionally use LLVM utilities
GNU's addr2line can have problems parsing a vmlinux built with LLVM,
particularly when LTO was used.  In order to decode the traces correctly
this patch adds the ability to switch to LLVM's utilities readelf and
addr2line.  The same approach is followed by Will in [1].

Before:
  $ scripts/decode_stacktrace.sh vmlinux < kernel.log
  [17716.240635] Call trace:
  [17716.240646] skb_cow_data (??:?)
  [17716.240654] esp6_input (ld-temp.o:?)
  [17716.240666] xfrm_input (ld-temp.o:?)
  [17716.240674] xfrm6_rcv (??:?)
  [...]

After:
  $ LLVM=1 scripts/decode_stacktrace.sh vmlinux < kernel.log
  [17716.240635] Call trace:
  [17716.240646] skb_cow_data (include/linux/skbuff.h:2172 net/core/skbuff.c:4503)
  [17716.240654] esp6_input (net/ipv6/esp6.c:977)
  [17716.240666] xfrm_input (net/xfrm/xfrm_input.c:659)
  [17716.240674] xfrm6_rcv (net/ipv6/xfrm6_input.c:172)
  [...]

Note that one could set CROSS_COMPILE=llvm- instead to hack around this
issue.  However, doing so can break the decodecode routine as it will
force the selection of other LLVM utilities down the line e.g.  llvm-as.

cc478e0b6b kasan: avoid resetting aux_lock
With commit 63b85ac56a ("kasan: stop leaking stack trace handles"),
KASAN zeroes out alloc meta when an object is freed.  The zeroed out data
purposefully includes alloc and auxiliary stack traces but also
accidentally includes aux_lock.

As aux_lock is only initialized for each object slot during slab creation,
when the freed slot is reallocated, saving auxiliary stack traces for the
new object leads to lockdep reports when taking the zeroed out aux_lock.

Arguably, we could reinitialize aux_lock when the object is reallocated,
but a simpler solution is to avoid zeroing out aux_lock when an object
gets freed.

aaa2c9a97c lib/Kconfig.debug: disable CONFIG_DEBUG_INFO_BTF for Hexagon
pahole, which generates BTF, relies on elfutils to process DWARF debug
info.  Because kernel modules are relocatable files, elfutils needs to
resolve relocations when processing the DWARF .debug sections.

Hexagon is not supported in binutils or elfutils, so elfutils is unable to
process relocations in kernel modules, causing pahole to crash during BTF
generation.

Do not allow CONFIG_DEBUG_INFO_BTF to be selected for Hexagon until it is
supported in elfutils, so that there are no more cryptic build failures
during BTF generation.

4a693ce65b kdump: defer the insertion of crashkernel resources
In /proc/iomem, sub-regions should be inserted after their parent,
otherwise the insertion of parent resource fails.  But after generic
crashkernel reservation applied, in both RISC-V and ARM64 (LoongArch will
also use generic reservation later on), crashkernel resources are inserted
before their parent, which causes the parent disappear in /proc/iomem.  So
we defer the insertion of crashkernel resources to an early_initcall().

42bff4d0f9 pwm: Changes for v6.8-rc1
This contains a bunch of cleanups and simplifications across the board,
 as well as a number of small fixes.
 
 Perhaps the most notable change here is the addition of an API that
 allows PWMs to be used in atomic contexts, which is useful when time-
 critical operations are involved, such as using a PWM to generate IR
 signals.
 
 Finally, I have decided to step down as PWM subsystem maintainer. Due to
 other responsibilities I have lately not been able to find the time that
 the subsystem deserves and Uwe, who has been helping out a lot for the
 past few years and has many things planned for the future, has kindly
 volunteered to take over. I have no doubt that he will be a suitable
 replacement.

141d9c6e00 firewire updates for 6.8
This update includes the series of changes related to device attributes,
 as well as slight code refactoring.
 
 Some old devices are recognized to have legacy layout of configuration ROM.
 They have an inconvenience that FireWire subsystem adds no attributes for
 vendor information to corresponding devices. The main purpose of this
 update is to rectify the inconvenience.
 
 We have a slight concern about regression. The update changes the value of
 modalias for the unit devices by populating its model field, which was
 previously left as zero in the case. I've assessed the potential impact of
 this change and anticipate it to have minimal concern for both the kernel
 and user lands. The change is enough acceptable.

c736c9a955 Only a couple new SoCs have support added this time, primarily for Qualcomm
SM8650 based on the diffstat. Otherwise this is a collection of non-critical
 fixes and cleanups to various clk drivers and their DT bindings. Nothing is
 changed in the core clk framework this time, although there's a patch to fix a
 basic clk type initialization function. In general, this pile looks to be on
 the smaller side.
 
 New Drivers:
  - Global, display, gpu, tcsr, and rpmh clocks on Qualcomm SM8650
  - Mediatek MT7988 SoC clocks

576db73424 gpio updates for v6.8
Core GPIOLIB:
 - protect the global list of GPIO devices with a read-write semaphore as
   it is rarely modified but can be traversed by multiple readers at once
 - remove GPIO devices from the global list when they are *unregistered*
   and not when they are *released* (which only happens when the last
   reference is dropped) as this may lead to a successful lookup of an
   unregistered device
 - remove the unnecessary "extra_checks" switch
 - rename functions that are called with a lock taken
 - remove duplicate includes
 
 Character device handling:
 - use locking guards to reduce the code size
 - allocate the big linereq structure using the more suitable kvzalloc()
 - redulce the size of critical sections
 - improve documentation
 - move the debounce_period_us field out of struct gpio_desc
 
 New drivers:
 - Nuvoton NPCM SGPIO driver for BMC NPCM7xx/NPCM8xx
 - Realtek DHC (Digital Home Center) SoC GPIO driver
 
 Driver improvements:
 - replace gpiochip_is_requested() with a safer alternative in the form of
   gpiochip_dup_line_label() as the former returns a pointer to a string that
   can be deleted
 - implement the dbg_show() callback in gpio-sim
 - improve the coding style for local variables by removing unnecessary tabs
 - use generic device properties instead of OF variants in gpio-mmio
 - use the preferred coding style for __free() in gpio-mockup
 - reuse PM ops from the gpio-tangier in gpio-elkhartlake
 - rework PM and use cleanup helpers in gpio-tangier
 - fix the EIC configuration in gpio-pmic-eic-sprd
 - remove the unneeded call to platform_set_drvdata() in gpio-sifive
 - use generic GPIO helpers for driver callbacks in gpio-dwapb
 - add clock support on certain pins of gpio-ixp4xx
 - don't use the core-specific DEBUG_GPIO switch in drivers
 - kerneldoc improvements
 
 DT bindings:
 - add bindings for the new Realtek and Nuvoton devices
 - allow gpio-ranges in gpio-dwapb
 - support GPIO hogs in gpio-rockchip
 - describe the label property in gpio-zynqmp-modepin
 
 Other:
 - header cleanups
 - forward declarations cleanups

Pull gpio updates from Bartosz Golaszewski:
 "We have two new drivers, an assortment of updates and cleanups to many
  others, and first part of the big rework of the core GPIOLIB that's
  currently underway.

  Add to that some code shrink in the character device module and
  updates to DT bindings and that's pretty much it.
