OneXPlayer devices have a charge inhibit feature that allows the user
to select between it being active always or only when the device is on.
Therefore, add attribute inhibit-charge-awake to charge_behaviour to
allow the user to select that charge should be paused only when the

The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional
functionality (turbo button, turbo led, battery controls).
As it will be beneficial from a complexity perspective to retain this
driver as a single unit, move it out of hwmon, and into platform/x86.
Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.
While at it, add myself to the maintainer's file.

The ACPI byte code inside the ACPI control method responsible for
handling the WMI method calls uses a global buffer for constructing
the return value, yet the ACPI control method itself is not marked
as "Serialized".
This means that calling WMI methods on this WMI device is not
thread-safe, as concurrent WMI method calls will corrupt the global
buffer.
Fix this by serializing the WMI method calls using a mutex.

It was mistaken that the physical memory returned from "reserve_mem" had to
be vmap()'d to get to it from a virtual address. But reserve_mem already
maps the memory to the virtual address of the kernel so a simple
phys_to_virt() can be used to get to the virtual address from the physical
memory returned by "reserve_mem". With this new found knowledge, the
code can be cleaned up and simplified.
- Enforce that the persistent memory is page aligned
As the buffers using the persistent memory are all going to be
mapped via pages, make sure that the memory given to the tracing
infrastructure is page aligned. If it is not, it will print a warning
and fail to map the buffer.
- Use phys_to_virt() to get the virtual address from reserve_mem
Instead of calling vmap() on the physical memory returned from
"reserve_mem", use phys_to_virt() instead.
As the memory returned by "memmap" or any other means where a physical
address is given to the tracing infrastructure, it still needs to
be vmap(). Since this memory can never be returned back to the buddy
allocator nor should it ever be memmory mapped to user space, flag
this buffer and up the ref count. The ref count will keep it from
ever being freed, and the flag will prevent it from ever being memory
mapped to user space.
- Use vmap_page_range() for memmap virtual address mapping
For the memmap buffer, instead of allocating an array of struct pages,
assigning them to the contiguous phsycial memory and then passing that to
vmap(), use vmap_page_range() instead
- Replace flush_dcache_folio() with flush_kernel_vmap_range()
Instead of calling virt_to_folio() and passing that to
flush_dcache_folio(), just call flush_kernel_vmap_range() directly.
This also fixes a bug where if a subbuffer was bigger than PAGE_SIZE
only the PAGE_SIZE portion would be flushed.

This contains:
- Fix for sendmsg zc, include in pinned pages accounting like we do
for the other zc types
- Series for ublk fixing request aborting, doing various little
cleanups, fixing some zc issues, and adding queue_rqs support
- Another ublk series doing some code cleanups
- Series cleaning up the io_uring send path, mostly in preparation
for registered buffers
- Series doing little MSG_RING cleanups
- Fix for the newly added zc rx, fixing len being 0 for the last
invocation of the callback
- Add vectored registered buffer support for ublk. With that, then
ublk also supports this feature in the kernel revision where it
could generically introduced for rw/net

Two significant new items:
- Allow reporting IOMMU HW events to userspace when the events are clearly
linked to a device. This is linked to the VIOMMU object and is intended to
be used by a VMM to forward HW events to the virtual machine as part of
emulating a vIOMMU. ARM SMMUv3 is the first driver to use this
mechanism. Like the existing fault events the data is delivered through
a simple FD returning event records on read().
- PASID support in VFIO. "Process Address Space ID" is a PCI feature that
allows the device to tag all PCI DMA operations with an ID. The IOMMU
will then use the ID to select a unique translation for those DMAs. This
is part of Intel's vIOMMU support as VT-D HW requires the hypervisor to
manage each PASID entry. The support is generic so any VFIO user could
attach any translation to a PASID, and the support should work on ARM
SMMUv3 as well. AMD requires additional driver work.
Some minor updates, along with fixes:
- Prevent using nested parents with fault's, no driver support today
- Put a single "cookie_type" value in the iommu_domain to indicate what
owns the various opaque owner fields

- A single fix making sure the EDAC subtree is included in the
documentation table of contents

Documentation/EDAC: Fix warning document isn't included in any toctree
- Use dev_err_probe() helpers to simplify the init code in the Qoriq
thermal driver (Frank Li).
- Power down the Qoriq's TMU at suspend time (Alice Guo).
- Add ipq5332, ipq5424 compatible to the QCom's tsens thermal driver
and TSENS enable / calibration support for V2 (Praveenkumar I).
- Add missing rk3328 mapping entry (Trevor Woerner).
- Remove duplicate struct declaration from the thermal core header
file (Xueqin Luo).
- Disable the monitoring mode during suspend in the LVTS Mediatek
driver to prevent temperature acquisition glitches (Nícolas F. R. A.
Prado).
- Disable Stage 3 thermal threshold in the LVTS Mediatek driver
because it disables the suspend ability and does not have an
interrupt handler (Nícolas F. R. A. Prado).
- Fix low temperature offset interrupt in the LVTS Mediatek driver
to prevent multiple interrupts from triggering when the system is at
its normal functionning temperature (Nícolas F. R. A. Prado).
- Enable interrupts in the LVTS Mediatek driver only on sensors that
are in use (Nícolas F. R. A. Prado).
- Add the BCM74110 compatible DT binding and the corresponding code
to support a chip based on a different process node than previous
chips (Florian Fainelli).
- Correct indentation and style in DTS example (Krzysztof Kozlowski).
- Unify hexadecimal annotatation in the rcar_gen3 driver (Niklas
Söderlund).
- Factor out the code logic to read fuses on Gen3 and Gen4 in the
rcar_gen3 thermal driver (Niklas Söderlund).
- Drop unused driver data from the QCom's spmi temperature alarm
driver (Johan Hovold).
