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"

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

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.

If the system has no mirrored memory or uses crashkernel.high while
kernelcore=mirror is enabled on the command line then during crashkernel,
there will be limited mirrored memory and this usually leads to OOM.

To solve this problem, disable the mirror feature during crashkernel.

syscore_shutdown() runs driver and module callbacks to get the system into
a state where it can be correctly shut down.  In commit 6f389a8f ("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 6735150b ("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 6f389a8f ("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 6f389a8f
("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.

With commit 63b85ac5 ("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.

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.

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().

 "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

Pull firewire updates from Takashi Sakamoto:
 "This 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"
