8c297fbdc3 misc: microchip: pci1xxxx: Fix missing spin_lock_init()
The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

ff0de066b4 hwtracing: hisi_ptt: Add trace function support for HiSilicon PCIe Tune and Trace device
HiSilicon PCIe tune and trace device(PTT) is a PCIe Root Complex integrated
Endpoint(RCiEP) device, providing the capability to dynamically monitor and
tune the PCIe traffic and trace the TLP headers.

Add the driver for the device to enable the trace function. Register PMU
device of PTT trace, then users can use trace through perf command. The
driver makes use of perf AUX trace function and support the following
events to configure the trace:

- filter: select Root port or Endpoint to trace
- type: select the type of traced TLP headers
- direction: select the direction of traced TLP headers
- format: select the data format of the traced TLP headers

This patch initially add basic trace support of PTT device.

269e633dad coresight: cti-sysfs: Mark coresight_cti_reg_store() as __maybe_unused
When building without CONFIG_CORESIGHT_CTI_INTEGRATION_REGS, there is a
warning about coresight_cti_reg_store() being unused in the file:

  drivers/hwtracing/coresight/coresight-cti-sysfs.c:184:16: warning: 'coresight_cti_reg_store' defined but not used [-Wunused-function]
    184 | static ssize_t coresight_cti_reg_store(struct device *dev,
        |                ^~~~~~~~~~~~~~~~~~~~~~~

This is expected as coresight_cti_reg_store() is only used in the
coresight_cti_reg_rw macro, which is only used in a block guarded by
CONFIG_CORESIGHT_CTI_INTEGRATION_REGS. Mark coresight_cti_reg_store() as
__maybe_unused to clearly indicate that the function may be unused
depending on the configuration.

information on the mapping from ADC channel to an analog signal
from another device. We've long since moved to doing this via

the only driver still providing this.

2bc9cd66eb iio: Use per-device lockdep class for mlock
If an IIO driver uses callbacks from another IIO driver and calls
iio_channel_start_all_cb() from one of its buffer setup ops, then
lockdep complains due to the lock nesting, as in the below example with
lmp91000.

Since the locks are being taken on different IIO devices, there is no
actual deadlock.  Fix the warning by telling lockdep to use a different
class for each iio_device.

The MAX11205 is compatible with the 2-wire interface and uses

controls are implemented by timing the high or low phase of the SCLK.

b0839b281c Makefile.extrawarn: re-enable -Wformat for clang; take 2
-Wformat was recently re-enabled for builds with clang, then quickly
re-disabled, due to concerns stemming from the frequency of default
argument promotion related warning instances.

commit 258fafcd06 ("Makefile.extrawarn: re-enable -Wformat for clang")
commit 21f9c8a13b ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")

ISO WG14 has ratified N2562 to address default argument promotion
explicitly for printf, as part of the upcoming ISO C2X standard.

The behavior of clang was changed in clang-16 to not warn for the cited
cases in all language modes.

Add a version check, so that users of clang-16 now get the full effect
of -Wformat. For older clang versions, re-enable flags under the
-Wformat group that way users still get some useful checks related to
format strings, without noisy default argument promotion warnings. I
intentionally omitted -Wformat-y2k and -Wformat-security from being
re-enabled, which are also part of -Wformat in clang-16.

 "Here are three small staging driver fixes for 6.0-rc4 that resolve
  some reported problems and add some a device id:

   - new device id for r8188eu driver

   - use-after-free bugfixes for the rtl8712 driver

   - fix up firmware dependency problem for the r8188eu driver

  All of these have been in linux-next for a while with no reported
  problems"

9a61442cba Here's a collection of primarily clk driver fixes, with a couple fixes
to the core framework. We had to revert out a commit that affected boot
 on some devices that have the CLK_OPS_PARENT_ENABLE flag set. It isn't
 critical to have that fix so we'll try again next time.
 
 Driver side fixes include:
 
  - Plug an of node refcount bug in the TI clk driver
 
  - Fix the error handling in the raspberry pi firmware get_rate
    so that errors don't look like valid frequencies
 
  - Avoid going out of bounds in the raspberry pi driver too if the
    video firmware returns something we're not expecting

8782fb61cc mm: pagewalk: Fix race between unmap and page walker
The mmap lock protects the page walker from changes to the page tables
during the walk.  However a read lock is insufficient to protect those
areas which don't have a VMA as munmap() detaches the VMAs before
downgrading to a read lock and actually tearing down PTEs/page tables.

For users of walk_page_range() the solution is to simply call pte_hole()
immediately without checking the actual page tables when a VMA is not
present. We now never call __walk_page_range() without a valid vma.

For walk_page_range_novma() the locking requirements are tightened to
require the mmap write lock to be taken, and then walking the pgd
directly with 'no_vma' set.

This in turn means that all page walkers either have a valid vma, or
it's that special 'novma' case for page table debugging.  As a result,
all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.

1a470ce4e9 LoongArch: Fix arch_remove_memory() undefined build error
The kernel build error when unslected CONFIG_MEMORY_HOTREMOVE because
arch_remove_memory() is needed by mm/memory_hotplug.c but undefined.

Some build error messages like:

 LD      vmlinux.o
 MODPOST vmlinux.symvers
 MODINFO modules.builtin.modinfo
 GEN     modules.builtin
 LD      .tmp_vmlinux.kallsyms1
loongarch64-linux-gnu-ld: mm/memory_hotplug.o: in function `.L242':
memory_hotplug.c:(.ref.text+0x930): undefined reference to `arch_remove_memory'
make: *** [Makefile:1169:vmlinux] 错误 1

Removed CONFIG_MEMORY_HOTREMOVE requirement and rearrange the file refer
to the definitions of other platform architectures.
