Pull netfs updates from Christian Brauner:
"This contains the netfs and cachefiles changes for this cycle from
David.

Cachefiles learns to cache the most common class of files properly,
files that are created or truncated, written once sequentially and
closed. So far it relied on the backing filesystem's idea of what is
stored and asked with SEEK_DATA and SEEK_HOLE before every read it
prepared, two seeks per read, and the backing filesystem is free to
insert or remove runs of zeros which produces false positives and
false negatives. The object type in the state xattr is now actually
set to CACHEFILES_CONTENT_{SINGLE,ALL,BACKFS_MAP} instead of zero. For
files written contiguously the type is ALL, the backing file's i_size
tracks how much is cached and the object size lives in the xattr, and
reads skip the seeks entirely. Netfslib queries the cache occupancy
through a new ->query_occupancy() method that returns up to two
extents at once, ->prepare_read() only limits the size of a cache read
anymore and a new ->collect_write() lets the cache update its metadata
once a contiguous run of writes completes. The state xattr is preset
when the tmpfile is created so ENOSPC from setxattr can't scrap a
fully written cache file. Two fixes for this followed, one for resize
handling where the cache's idea of the size can be stale and one for
an unset error that hung a request on a failed cache write.

Preparatory work converts file positions that can't be negative to
uoff_t, removes the writethrough code whose locking looked like it
could deadlock with ceph snapshots, makes the deprecated PG_private_2
support opt-in so mm can get its page bit back, adds helpers for the
NETFS_RREQ_ALL_QUEUED barriers and adds the cache object id to the
read and write tracepoints. Plus an unused header removal and two
documentation fixes"

Merge patch series "netfs: Miscellaneous preparatory changes"

David Howells <dhowells@redhat.com> says:

netfs: Miscellaneous preparatory changes

This a collection of miscellaneous modifications to netfslib that I want to
make ahead of bigger changes, including:

(1) Convert "unsigned long long" to "uoff_t". This makes it a little more
obvious as to the meaning of the value. Also convert some "loff_t" to
"uoff_t" as most of the time it's used the value really should never
be negative.

(2) Remove the writethrough code as the locking is really tricky to get
right and it looks like it could deadlock with Ceph if snapshots are
used.

(3) Adjust some tracepoints, including adding the cache object ID to
certain tracepoinits.

(4) Make use of PG_private_2 opt-in. Use of PG_private_2 is deprecated
and the MM people would like their page bit back, so we need to stop
using it soon.

(5) Add some helper functions to handle the barriering needed for the
NETFS_RREQ_ALL_QUEUED flag.

(6) Set the subrequest type at allocation time so that the allocation
trace records the proposed type.

Merge branch 'nesting_reserved_regions' into iommufd.git for-next

Nicolin Chen says:

=========
IOMMU_RESV_SW_MSI is a unique region defined by an IOMMU driver. Though it
is eventually used by a device for address translation to an MSI location
(including nested cases), practically it is a universal region across all
domains allocated for the IOMMU that defines it.

Currently IOMMUFD core fetches and reserves the region during an attach to
an hwpt_paging. It works with a hwpt_paging-only case, but might not work
with a nested case where a device could directly attach to a hwpt_nested,
bypassing the hwpt_paging attachment.

Move the enforcement forward, to the hwpt_paging allocation function. Then
clean up all the SW_MSI related things in the attach/replace routine.

Based on v6.11-rc5 for dependencies.

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.
