Merge tag 'i2c-host-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow
The DesignWare and the Renesas I2C drivers have received most of the changes in this pull request.
The first has has undergone through a series of cleanups that have been sent to the mailing list a year ago for the first time and finally get merged in this pull request. They are many, from typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline functions to librarieas) and many others.
Besides that, all the DesignWare Kconfig options have been grouped under the I2C_DESIGNWARE_CORE and this required some adaptation in many of the kernel configuration files for different arm and mips boards.
Follows the list of the rest of the changes grouped by type of change.
Cleanups -------- The Qualcomm Geni platform improves the exit path in the runtime resume function.
The Intel LJCA driver loses "target_addr" parameter in ljca_i2c_stop() because it was unused.
The MediaTek controller intializes the restart_flag in the transfer function using the ternary conditional operator ("? :") instead of initializing it in different parts.
Constified a few global data structures in the virtio driver.
The Renesas driver simplifies the bus speed handling in the init function making it more readable.
Improved an if/else statement in probe function of the Renesas R-Car driver.
The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead of SET_RUNTIME_PM_OPS().
Still in the iMX/MXC driver a comma ',' has been replaced by a semicolon ';', while in different drivers the ',' has been removed from the '{ }' delimiters.
Finally three devm_clk_get_enabled() have been used to simplify the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2, Ingenic and MPC drivers.
Refactors --------- The Nuvoton fixes a potential out of boundary array access. This is not a bug fix because the issue could never occur due to hardware not having the properties listed in the array. The change makes the driver more future proof and, at the same time, silences code analyzers.
Improvements ------------ The Renesas I2C (riic) driver undergoes several patches improving the runtime power management handling.
The Intel i801 driver uses a more descriptive adapter's name to show the presence of the IDF feature.
In the Intel Denverton (ismt) adapter the pending transactions are killed when irq's can't complete their handling, triggering a timeout. This could have been considered as a bug fix, but because, standing to Vasily, it's very sporadic, I preferred considering the patch rather as an improvement.
New Feature ----------- The Renesas I2C (riic) driver now supports the fast mode plus.
New support ----------- Added support for:
- Renesas R9A08G045 - Rockchip RK3576 - KEBA I2C - Theobroma Systems Mule Multiplexer.
The Keba comes with a new driver, i2c-keba.c. The Mule is an i2c multiplexer and it also comes with a new driver, mux/i2c-mux-mule.c.
Core patch ---------- This pull request includes also a patch in the I2C framework, in i2c-core-base.c where the runtime PM functions have been replaced in order to allow to be accessed during the device add.
Devicetree ---------- Some cleanups in the devicetree, as well. nVidia and Qualcomm bindings improve their "if:then:" blocks. While the aspeed binding loses the "multi-master" property because it was redundant.
The i2c-sprd binding has been converted to YAML.

Merge remote-tracking branch 'torvalds/master' into perf-tools-next
To pick up fixes from perf-tools/perf-tools, some of which were also in perf-tools-next but were then indentified as being more appropriate to go sooner, to fix regressions in v6.11.
Resolve a simple merge conflict in tools/perf/tests/pmu.c where a more future proof approach to initialize all fields of a struct was used in perf-tools-next, the one that is going into v6.11 is enough for the segfault it addressed (using an uninitialized test_pmu.alias field).

Merge tag 'i2c-host-fixes-6.11-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
The Aspeed driver tracks the controller's state (stop, pending, start, etc.). Previously, when the stop command was sent, the state was not updated. The fix in this pull request ensures the driver's state is aligned with the device status.
The Intel SCH driver receives a new look, and among the cleanups, there is a fix where, due to an oversight, an if/else statement was missing the else, causing it to move forward instead of exiting the function in case of an error.
The Qualcomm GENI I2C driver adds the IRQF_NO_AUTOEN flag to the IRQ setup to prevent unwanted interrupts during probe.
The Xilinx XPS controller fixes TX FIFO handling to avoid missed NAKs. Another fix ensures the controller is reinitialized when the bus appears busy.

Merge tag 'vfs-6.12.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner: "This contains the work to improve read/write performance for the new netfs library.
The main performance enhancing changes are:
- Define a structure, struct folio_queue, and a new iterator type, ITER_FOLIOQ, to hold a buffer as a replacement for ITER_XARRAY. See that patch for questions about naming and form.
ITER_FOLIOQ is provided as a replacement for ITER_XARRAY. The problem with an xarray is that accessing it requires the use of a lock (typically the RCU read lock) - and this means that we can't supply iterate_and_advance() with a step function that might sleep (crypto for example) without having to drop the lock between pages. ITER_FOLIOQ is the iterator for a chain of folio_queue structs, where each folio_queue holds a small list of folios. A folio_queue struct is a simpler structure than xarray and is not subject to concurrent manipulation by the VM. folio_queue is used rather than a bvec[] as it can form lists of indefinite size, adding to one end and removing from the other on the fly.
- Provide a copy_folio_from_iter() wrapper.
- Make cifs RDMA support ITER_FOLIOQ.
- Use folio queues in the write-side helpers instead of xarrays.
- Add a function to reset the iterator in a subrequest.
- Simplify the write-side helpers to use sheaves to skip gaps rather than trying to work out where gaps are.
- In afs, make the read subrequests asynchronous, putting them into work items to allow the next patch to do progressive unlocking/reading.
- Overhaul the read-side helpers to improve performance.
- Fix the caching of a partial block at the end of a file.
- Allow a store to be cancelled.
Then some changes for cifs to make it use folio queues instead of xarrays for crypto bufferage:
- Use raw iteration functions rather than manually coding iteration when hashing data.
- Switch to using folio_queue for crypto buffers.
- Remove the xarray bits.
Make some adjustments to the /proc/fs/netfs/stats file such that:
- All the netfs stats lines begin 'Netfs:' but change this to something a bit more useful.
- Add a couple of stats counters to track the numbers of skips and waits on the per-inode writeback serialisation lock to make it easier to check for this as a source of performance loss.
Miscellaneous work:
- Ensure that the sb_writers lock is taken around vfs_{set,remove}xattr() in the cachefiles code.
- Reduce the number of conditional branches in netfs_perform_write().
- Move the CIFS_INO_MODIFIED_ATTR flag to the netfs_inode struct and remove cifs_post_modify().
- Move the max_len/max_nr_segs members from netfs_io_subrequest to netfs_io_request as they're only needed for one subreq at a time.
- Add an 'unknown' source value for tracing purposes.
- Remove NETFS_COPY_TO_CACHE as it's no longer used.
- Set the request work function up front at allocation time.
- Use bh-disabling spinlocks for rreq->lock as cachefiles completion may be run from block-filesystem DIO completion in softirq context.
- Remove fs/netfs/io.c"

netfs: Speed up buffered reading
Improve the efficiency of buffered reads in a number of ways:
(1) Overhaul the algorithm in general so that it's a lot more compact and split the read submission code between buffered and unbuffered versions. The unbuffered version can be vastly simplified.
(2) Read-result collection is handed off to a work queue rather than being done in the I/O thread. Multiple subrequests can be processes simultaneously.
(3) When a subrequest is collected, any folios it fully spans are collected and "spare" data on either side is donated to either the previous or the next subrequest in the sequence.
Notes:
(*) Readahead expansion is massively slows down fio, presumably because it causes a load of extra allocations, both folio and xarray, up front before RPC requests can be transmitted.
(*) RDMA with cifs does appear to work, both with SIW and RXE.
(*) PG_private_2-based reading and copy-to-cache is split out into its own file and altered to use folio_queue. Note that the copy to the cache now creates a new write transaction against the cache and adds the folios to be copied into it. This allows it to use part of the writeback I/O code.

netfs: Simplify the writeback code
Use the new folio_queue structures to simplify the writeback code. The problem with referring to the i_pages xarray directly is that we may have gaps in the sequence of folios we're writing from that we need to skip when we're removing the writeback mark from the folios we're writing back from.
At the moment the code tries to deal with this by carefully tracking the gaps in each writeback stream (eg. write to server and write to cache) and divining when there's a gap that spans folios (something that's not helped by folios not being a consistent size).
Instead, the folio_queue buffer contains pointers only the folios we're dealing with, has them in ascending order and indicates a gap by placing non-consequitive folios next to each other. This makes it possible to track where we need to clean up to by just keeping track of where we've processed to on each stream and taking the minimum.
Note that the I/O iterator is always rounded up to the end of the folio, even if that is beyond the EOF position, so that the cache can do DIO from the page. The excess space is cleared, though mmapped writes clobber it.

Make the netfs write-side routines use the new folio_queue struct to hold a rolling buffer of folios, with the issuer adding folios at the tail and the collector removing them from the head as they're processed instead of using an xarray.
This will allow a subsequent patch to simplify the write collector.
The primary mark (as tested by folioq_is_marked()) is used to note if the corresponding folio needs putting.
