The ASUS ROG Zephyrus Duo 15 SE (GX551QS) with ALC 289 codec requires specific
pin configuration for proper volume control. Without this quirk, volume
adjustments produce a muffled sound effect as only certain channels attenuate,
leaving bass frequency at full volume.
Testing with hdajackretask confirms these pin tweaks fix the issue:
- Pin 0x17: Internal Speaker (LFE)
- Pin 0x1e: Internal Speaker

Rename intel_get_linetime_us() to skl_wm_linetime_us() to better
reflect that it's not meant to be used for anything apart from

intel_get_linetime_us() is a mess. Rewrite it in a straightforward
manner. Also the checks for the !active and pixel_rate==0 are
completely pointless here since we know that the plane is visible.

The line time used for the watermark calculations is supposed to
based on the plane's adjusted pixel rate, not the pipe's adjusted
pixel rate. The current code will give incorrect answers if plane
downscaling is used.

The RZ/G2L DU driver is now also used on other Renesas SoCs such as
RZ/V2H(P) and RZ/V2N. Restricting it to ARCH_RZG2L prevents enabling it
on these newer platforms.
Replace the ARCH_RZG2L dependency with ARCH_RENESAS to allow the driver
to be built on all relevant Renesas SoCs.

Add support for the internal I2C controllers of RTL9310 series based
SoCs to the driver for RTL9300. Add register definitions, chip-specific
functions and compatible strings for known RTL9310-based SoCs RTL9311,
RTL9312 and RTL9313.
Make use of a new device tree property 'realtek,scl' which needs to be
specified in case both or only the second master is used. This is
required due how the register layout changed in contrast to RTL9300,
which has SCL selection in a global register instead of a
master-specific one.

Adjust the regex for child-node address to account for the fact that
RTL9310 supports 12 instead of only 8 SDA lines. Also, narrow this per
variant.
Add a vendor-specific property to explicitly specify the SCL line number
of the defined I2C controller/master. This is required, in particular
for RTL9310, to operate on the correct SCL for each controller. Require
this property to be specified for RTL9310.
Add compatibles for known SoC variants RTL9311, RTL9312 and RTL9313.

Use the scoped guard infrastructure which unlocks a mutex automatically
when the guard goes out of scope, instead of explicit lock and unlock.
This simplifies the code and control flow in rtl9300_i2c_smbus_xfer and
removes the need of using goto in error cases to unlock before
returning.

So far, the rtl9300_i2c_smbus_xfer code is quite a mess with function
calls distributed over the whole function setting different values in
different cases. Calls to rtl9300_i2c_config_xfer and
rtl9300_i2c_reg_addr_set are used in every case-block with varying
values whose meaning is not instantly obvious. In some cases, there are
additional calls within these case-blocks doing more things.
This is in general a bad design and especially really bad for
readability and maintainability because it distributes changes or
issues to multiple locations due to the same function being called with
different hardcoded values in different places.
To have a good structure, setting different parameters based on the
desired operation should not be interleaved with applying these
parameters to the hardware registers. Or in different words, the
parameter site should be mixed with the call site.
Thus, separate configuration and execution of an SMBus xfer within
rtl9300_i2c_smbus_xfer to improve readability and maintainability. Add a
new 'struct rtl9300_i2c_xfer' to carry the required parameters for an
xfer which are configured based on the input parameters within a single
switch-case block, without having any function calls within this block.
The function calls to actually apply these values to the hardware
registers then appear below in a single place and just operate on the
passed instance of 'struct rtl9300_i2c_xfer'. These are
'rtl9300_i2c_prepare_xfer' which combines applying all parameters of the
xfer to the corresponding register, and 'rtl9300_i2c_do_xfer' which
actually executes the xfer and does post-processing if needed.

Move the operation to set the read mode from config_xfer to probe.
The I2C controller of RTL9300 and RTL9310 support a legacy message mode
for READs with 'Read Address Data' instead of the standard format 'Write
Address ; Read Data'. There is no way to pass that via smbus_xfer, thus
there is no point in supported this in the driver and moreover no point
in setting this on every transaction. Setting this once in the probe
call is sufficient.

Rename the internally used 'sda_pin' to 'sda_num' to make it clear that
this is NOT the actual pin number of the GPIO pin but rather the logical
SDA channel number. Although the alternate function SDA_Y is sometimes
given with the GPIO number, this is not always the case. Thus, avoid any
confusion or misconfiguration by giving the variable the correct name.
This follows the description change in the devicetree bindings.

SoCs.

Adapt the RTL9300 I2C controller driver to use more of the regmap
API, especially make use of reg_field and regmap_field instead of macros
to represent registers. Most register operations are performed through
regmap_field_* API then.
Handle SCL selection using separate chip-specific functions since this
is already known to differ between the Realtek SoC families in such a
way that this cannot be properly handled using just a different
reg_field.
This makes it easier to add support for newer generations or to handle
differences between specific revisions within a series. Just by
defining a separate driver data structure with the corresponding
register field definitions and linking it to a new compatible.

It was noticed that the original implementation of SMBus Block Write in the
driver was actually an I2C Block Write. Both differ only in the Count byte
before the actual data:
S Addr Wr [A] Comm [A] Count [A] Data [A] Data [A] ... [A] Data [A] P
The I2C Block Write is just skipping this Count byte and starts directly
with the data:
S Addr Wr [A] Comm [A] Data [A] Data [A] ... [A] Data [A] P
The I2C controller of RTL93xx doesn't handle this Count byte special and it
is simply another one of (16 possible) data bytes. Adding support for the
I2C Block Write therefore only requires skipping the count byte (0) in
data->block.
It is similar for reads. The SMBUS Block read is having a Count byte before
the data:
S Addr Wr [A] Comm [A]
Sr Addr Rd [A] [Count] A [Data] A [Data] A ... A [Data] NA P
And the I2C Block Read is directly starting with the actual data:
S Addr Wr [A] Comm [A]
Sr Addr Rd [A] [Data] A [Data] A ... A [Data] NA P
The I2C controller is also not handling this byte in a special way. It
simply provides every byte after the Rd marker + Ack as part of the 16 byte
receive buffer (registers). The content of this buffer just has to be
copied to the right position in the receive data->block.

Add bounds checking to prevent writes past framebuffer boundaries when
rendering text near screen edges. Return early if the Y position is off-screen
and clip image height to screen boundary. Break from the rendering loop if the
X position is off-screen. When clipping image width to fit the screen, update
the character count to match the clipped width to prevent buffer size
mismatches.
Without the character count update, bit_putcs_aligned and bit_putcs_unaligned
receive mismatched parameters where the buffer is allocated for the clipped
width but cnt reflects the original larger count, causing out-of-bounds writes.

Pull dma-mapping updates from Marek Szyprowski:
- Refactoring of DMA mapping API to physical addresses as the primary
interface instead of page+offset parameters
This gets much closer to Matthew Wilcox's long term wish for
struct-pageless IO to cacheable DRAM and is supporting memdesc
project which seeks to substantially transform how struct page works.
An advantage of this approach is the possibility of introducing
DMA_ATTR_MMIO, which covers existing 'dma_map_resource' flow in the
common paths, what in turn lets to use recently introduced
dma_iova_link() API to map PCI P2P MMIO without creating struct page
Developped by Leon Romanovsky and Jason Gunthorpe

Let's simplify the implementation. The current code is redundant as it
effectively expands to:
is_swap_pte(pte) &&
is_pte_marker_entry(...) && // from is_pte_marker()
is_pte_marker_entry(...) // from is_guard_swp_entry()
While a modern compiler could likely optimize this away, let's have clean
code and not rely on it.

Now the node id only needs to be set for early memory, so move
memory_block_add_nid() into the caller and rename it into
memory_block_add_nid_early(). This allows us to further simplify the code
by dropping the 'context' argument to
do_register_memory_block_under_node().

The sysfs attributes for memory blocks require the node ID to be set and
initialized, so move the node activation before adding new memory blocks.
This also has the nice side effect that the BUG_ON() can be converted into
a WARN_ON() as we now can handle registration errors.

Patch series "mm/memory_hotplug: fixup crash during uevent handling", v4.
we have some udev rules trying to read the sysfs attribute 'valid_zones'
during an memory 'add' event, causing a crash in zone_for_pfn_range().
Debugging found that mem->nid was set to NUMA_NO_NODE, which crashed in
NODE_DATA(nid). Further analysis revealed that we're running into a race
with udev event processing: add_memory_resource() has this function calls:
1) __try_online_node()
2) arch_add_memory()
3) create_memory_block_devices()
-> calls device_register() -> memory 'add' event
4) node_set_online()/__register_one_node()
-> calls device_register() -> node 'add' event
5) register_memory_blocks_under_node()
-> sets mem->nid
Which, to the uninitated, is ... weird ...
Why do we try to online the node in 1), but only register the node in 4)
_after_ we have created the memory blocks in 3) ? And why do we set the
'nid' value in 5), when the uevent (which might need to see the correct
'nid' value) is sent out in 3) ? There must be a reason, I'm sure ...
So here's a small patchset to fixup uevent ordering. The first patch adds
a 'nid' parameter to add_memory_blocks() (to avoid mem->nid being
initialized with NUMA_NO_NODE), and the second patch reshuffles the code
in add_memory_resource() to fully initialize the node prior to calling
create_memory_block_devices() so that the node is valid at that time and
uevent processing will see correct values in sysfs.

Metrics may generate many particularly uncore event references. The
resulting event string may then be >32kb. The parse events lex is
using "%option reject" which stores backtracking state in a buffer
sized at roughtly 30kb. If the event string is larger than this then a
buffer overflow and typically a crash happens.
The need for "%option reject" was for BPF events which were removed in
commit 3d6dfae88917 ("perf parse-events: Remove BPF event
support"). As "%option reject" is both a memory and performance cost
let's remove it and fix the parsing case for event strings being over
~30kb.
Whilst cleaning up "%option reject" make the header files accurately
reflect functions used in the code and tidy up not requiring yywrap.
Measuring on the "PMU JSON event tests" a modest reduction of 0.41%
user time and 0.27% max resident size was observed. More importantly
this change fixes parsing large metrics and event strings.

Pull f2fs updates from Jaegeuk Kim:
"This focuses on two primary updates for Android devices.
First, it sets hash-based file name lookup as the default method to
improve performance, while retaining an option to fall back to a
linear lookup.
Second, it resolves a persistent issue with the 'checkpoint=enable'
feature.
The update further boosts performance by prefetching node blocks,
merging FUA writes more efficiently, and optimizing block allocation
policies.
The release is rounded out by a comprehensive set of bug fixes that
address memory safety, data integrity, and potential system hangs,
along with minor documentation and code clean-ups.
Enhancements:
- add mount option and sysfs entry to tune the lookup mode
- dump more information and add a timeout when enabling/disabling
checkpoints
- readahead node blocks in F2FS_GET_BLOCK_PRECACHE mode
- merge FUA command with the existing writes
- allocate HOT_DATA for IPU writes
- Use allocate_section_policy to control write priority in
multi-devices setups
- add reserved nodes for privileged users
- Add bggc_io_aware to adjust the priority of BG_GC when issuing IO
- show the list of donation files

git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/exfat
Pull exfat updates from Namjae Jeon:
- Add support for FS_IOC_{GET,SET}FSLABEL ioctl
- Two small clean-up patches
- Optimizes allocation bitmap loading time on large partitions with
small cluster sizes
- Allow changes for discard, zero_size_dir, and errors options via
remount
- Validate that the clusters used for the allocation bitmap are
correctly marked as in-use during mount, preventing potential data
corruption from reallocating the bitmap's own space
- Uses ratelimit to avoid too many error prints on I/O error path

Pull orangefs updates from Mike Marshall:
"Two cleanups and a bug fix:
- Remove unused type in macro fill_default_sys_attrs (Zhen Ni)
- Replace kzalloc + copy_from_user with memdup_user_nul (Thorsten Blum)
- Fix xattr related buffer overflow...
A message was forwarded to me from Disclosure <disclosure@aisle.com>
indicating a problem with a loop condition in our xattr code. When
I fixed the problem it exposed a related memory leak problem, and I
fixed that too"

Pull ext4 updates from Ted Ts'o:
"New ext4 features:
- Add support so tune2fs can modify/update the superblock using an
ioctl, without needing write access to the block device
- Add support for 32-bit reserved uid's and gid's
Bug fixes:
- Fix potential warnings and other failures caused by corrupted /
fuzzed file systems
- Fail unaligned direct I/O write with EINVAL instead of silently
falling back to buffered I/O
- Correectly handle fsmap queries for metadata mappings
- Avoid journal stalls caused by writeback throttling
- Add some missing GFP_NOFAIL flags to avoid potential deadlocks
under extremem memory pressure
Cleanups:
- Remove obsolete EXT3 Kconfigs"
