The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Message Handling Unit version is v2.1.
When arm_mhuv2 working with the data protocol transfer mode.
We have split one mhu into two channels, and every channel
include four channel windows, the two channels share
one gic spi interrupt.
There is a problem with the sending scenario.
The first channel will take up 0-3 channel windows, and the second
channel take up 4-7 channel windows. When the first channel send the
data, and the receiver will clear all the four channels status.
Although we only enabled the interrupt on the last channel window with
register CH_INT_EN,the register CHCOMB_INT_ST0 will be 0xf, not be 0x8.
Currently we just clear the last channel windows int status with the
data proctol mode.So after that,the CHCOMB_INT_ST0 status will be 0x7,
not be the 0x0.
Then the second channel send the data, the receiver read the
data, clear all the four channel windows status, trigger the sender
interrupt. But currently the CHCOMB_INT_ST0 register will be 0xf7,
get_irq_chan_comb function will always return the first channel.
So this patch clear all channel windows int status to avoid this interrupt
confusion.

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.

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)

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.

syscore_shutdown() runs driver and module callbacks to get the system into
a state where it can be correctly shut down. In commit 6f389a8f1dd2 ("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 6735150b6997 ("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 6f389a8f1dd2 ("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 6f389a8f1dd2
("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.

memory range. Depending upon the number of iterations, different memory
ranges would be invalidated.
The following warning would be removed by this patch:
WARNING: CPU: 0 PID: 5067 at arch/x86/kvm/../../../virt/kvm/kvm_main.c:734 kvm_mmu_notifier_change_pte+0x860/0x960 arch/x86/kvm/../../../virt/kvm/kvm_main.c:734
There is no behavioural and performance change with this patch when
there is no component registered with the mmu notifier.

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.

With commit 63b85ac56a64 ("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().

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"
