i2c: rtl9300: use regmap fields and API for registers
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.

i2c: rtl9300: Implement I2C block read and write
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.

fbdev: Add bounds checking in bit_putcs to fix vmalloc-out-of-bounds
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.

It has been a relatively busy cycle in docsland, with changes all over:
- Bring the kernel memory-model docs into the Sphinx build in the "literal
include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate HTML
redirects; this can be used on kernel.org (or any other site hosting the
rendered docs) to avoid breaking links.
- Automated processing of the YAML files describing the netlink protocol.
- A significant update of the maintainer's PGP guide.
...and a seemingly endless series of typo fixes, build-problem fixes, etc.

mm: clean up is_guard_pte_marker()
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.

drivers/base: move memory_block_add_nid() into the caller
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().

mm/memory_hotplug: activate node before adding new memory blocks
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.

drivers/base/memory: add node id parameter to add_memory_block()
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.

perf parse-events: Fix parsing of >30kb event strings
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

f2fs-for-6.18-rc1
This release 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.
Enhancement:
- 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
Bug fix:
- add missing dput() when printing the donation list
- fix UAF issue in f2fs_merge_page_bio()
- add sanity check on ei.len in __update_extent_tree_range()
- fix infinite loop in __insert_extent_tree()
- fix zero-sized extent for precache extents
- fix to mitigate overhead of f2fs_zero_post_eof_page()
- fix to avoid migrating empty section
- fix to truncate first page in error path of f2fs_truncate()
- fix to update map->m_next_extent correctly in f2fs_map_blocks()
- fix wrong layout information on 16KB page
- fix to do sanity check on node footer for non inode dnode
- fix to avoid NULL pointer dereference in f2fs_check_quota_consistency()
- fix to detect potential corrupted nid in free_nid_list
- fix to clear unusable_cap for checkpoint=enable
- fix to zero data after EOF for compressed file correctly
- fix to avoid overflow while left shift operation
- fix condition in __allow_reserved_blocks()

Description for this pull request:
- 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.

perf record: Add ratio-to-prev term
Provide ratio-to-prev term which allows the user to set the event sample period of two events corresponding to a desired ratio. If using on an Intel x86 platform with Auto Counter Reload support, also set corresponding event's config2 attribute with a bitmask which counters to reset and which counters to sample if the desired ratio is met or exceeded. On other platforms, only the sample period is affected by the ratio-to-prev term.

Instead of preserving mode, timestamp, and owner, for the object files during installation, just preserve the mode and timestamp. When installing as root, the installed files should be owned by root. When installing as user, --preserve=ownership doesn't work anyway. This makes --preserve=ownership rather pointless.
