ab7b884a34 remoteproc updates for v6.10
This makes the remoteproc core rproc_class const.
 
 DeviceTree bindings for a few different Qualcomm remoteprocs are updated
 to remove a range of validation warnings/errors.  The Qualcomm SMD
 binding marks qcom,ipc deprecated, in favor or the mailbox interface.
 
 The TI K3 R5 remoteproc driver is updated to ensure that cores are
 powered up in the appropriate order. The driver also see a couple of
 fixes related to cleanups in error paths during probe.
 
 The Mediatek remoteproc driver is extended to support the MT8188 SCP
 core 1. Support for varying DRAM and IPI shared buffer sizes are
 introduced. This together with a couple of bug fixes and improvements to
 the driver.
 
 Support for the AMD-Xilinx Versal and Versal-NET platforms are added.
 Coredump support and support for parsing TCM information from DeviceTree
 is added to the Xilinx R5F remoteproc driver.

fa8151cabf Hi,
These are couple of bugs I found from trusted keys while working on a new
 asymmetric key type for TPM2 [1]. Both originate form v5.13. Memory leak is
 more crucial but I don't think it is either good idea if kernel throws WARN
 when ASN.1 parser fails, even if it is related to programming error, as it
 is not that mature code yet.
 
 There's at least two WARN's in that code but I picked just the one more
 likely to trigger. Planning to fix the other one too over time.

adbc49a5a8 gpiolib: acpi: Fix failed in acpi_gpiochip_find() by adding parent node match
Previous patch modified the standard used by acpi_gpiochip_find()
to match device nodes. Using the device node set in gc->gpiodev->d-
ev instead of gc->parent.

However, there is a situation in gpio-dwapb where the GPIO device
driver will set gc->fwnode for each port corresponding to a child
node under a GPIO device, so gc->gpiodev->dev will be assigned the
value of each child node in gpiochip_add_data().

gpio-dwapb.c:
128,31 static int dwapb_gpio_add_port(struct dwapb_gpio *gpio,
			       struct dwapb_port_property *pp,
			       unsigned int offs);
port->gc.fwnode = pp->fwnode;

693,39 static int dwapb_gpio_probe;
err = dwapb_gpio_add_port(gpio, &pdata->properties[i], i);

When other drivers request GPIO pin resources through the GPIO device
node provided by ACPI (corresponding to the parent node), the change
of the matching object to gc->gpiodev->dev in acpi_gpiochip_find()
only allows finding the value of each port (child node), resulting
in a failed request.

Reapply the condition of using gc->parent for match in acpi_gpio-
chip_find() in the code can compatible with the problem of gpio-dwapb,
and will not affect the two cases mentioned in the patch:
1. There is no setting for gc->fwnode.
2. The case that depends on using gc->fwnode for match.

Fixes: 5062e4c14b ("gpiolib: acpi: use the fwnode in acpi_gpiochip_find()")
Fixes: 067dbc1ea5 ("gpiolib: acpi: Don't use GPIO chip fwnode in acpi_gpiochip_find()")

db3d841ac9 fs/pidfs: make 'lsof' happy with our inode changes
pidfs started using much saner inodes in commit b28ddcc32d ("pidfs:
convert to path_from_stashed() helper"), but that exposed the fact that
lsof had some knowledge of just how odd our old anon_inode usage was.

For example, legacy anon_inodes hadn't even initialized the inode type
in the inode mode, so everything had a type of zero.

So sane tools like 'stat' would report these files as "weird file", but
'lsof' instead used that (together with the name of the link in proc) to
notice that it's an anonymous inode, and used it to detect pidfd files.

Let's keep our internal new sane inode model, but mask the file type
bits at 'stat()' time in the getattr() function we already have, and by
making the dentry name match what lsof expects too.

This keeps our internal models sane, but should make user space see the
same old odd behavior.

050bf3c793 KEYS: trusted: Do not use WARN when encode fails
When asn1_encode_sequence() fails, WARN is not the correct solution.

1. asn1_encode_sequence() is not an internal function (located
   in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.

It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.

Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

1b03616209 soc: devicetree updates for v6.10, part 2
This is a follow-up to an earlier pull request for device tree changes,
 as three platform maintainers sent their contents too late to be included
 in the main set, but had not caused any further problems since then:
 
  - The Amlogic platform now containts support for two new SoC types,
    the A4 and A5 chips for audio applications. Both come with a
    reference board, and one more dts file gets addded for the
    combination of the MNT Reform Laptop with the BPI-CM4 CPU
    module
 
  - The ASpeed platform adds support for six addititional server
    platforms that use ast2500 or ast2600 as their BMC, while
    another one gets removed.
 
  - The RISC-V platforms from Microchip, Starfive and and T-HEAD
    get additional features for existing hardware, plus the
    addition of the Milk-V Mars based on the StarFive VisionFive v2
    board.

34cda5ab89 arch: Fix name collision with ACPI's video.o
Commit 2fd001cd36 ("arch: Rename fbdev header and source files")
renames the video source files under arch/ such that they do not
refer to fbdev any longer. The new files named video.o conflict with
ACPI's video.ko module. Modprobing the ACPI module can then fail with
warnings about missing symbols, as shown below.

  (i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_unregister (err -2)
  (i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_register_backlight (err -2)

  (i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_register (err -2)

Fix the issue by renaming the architecture's video.o to video-common.o.

72ece20127 f2fs update for 6.10-rc1
In this round, we've tried to address some performance issues on zoned storage
 such as direct IO and write_hints. In addition, we've migrated some IO paths
 using folio. Meanwhile, there are multiple bug fixes in the compression paths,
 sanity check conditions, and error handlers.
 
 Enhancement:
  - allow direct io of pinned files for zoned storage
  - assign the write hint per stream by default
  - convert read paths and test_writeback to folio
  - avoid allocating WARM_DATA segment for direct IO
 
 Bug fix:
  - fix false alarm on invalid block address
  - fix to add missing iput() in gc_data_segment()
  - fix to release node block count in error path of f2fs_new_node_page()
  - compress: don't allow unaligned truncation on released compress inode
  - compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
  - compress: fix error path of inc_valid_block_count()
  - compress: fix to update i_compr_blocks correctly
  - fix block migration when section is not aligned to pow2
  - don't trigger OPU on pinfile for direct IO
  - fix to do sanity check on i_xattr_nid in sanity_check_inode()
  - write missing last sum blk of file pinning section
  - clear writeback when compression failed
  - fix to adjust appropirate defragment pg_end
 
 As usual, there are several minor code clean-ups, and fixes to manage missing
 corner cases in the error paths.

119d1b8a5d New code for 6.10:
* Introduce Parent Pointer extended attribute for inodes.
 
   * Online Repair
     - Implement atomic file content exchanges i.e. exchange ranges of bytes
       between two files atomically.
     - Create temporary files to repair file-based metadata. This uses atomic
       file content exchange facility to swap file fork mappings between the
       temporary file and the metadata inode.
 
     - Allow callers of directory/xattr code to set an explicit owner number to
       be written into the header fields of any new blocks that are created.
       This is required to avoid walking every block of the new structure and
       modify their ownership during online repair.
     - Repair
       - Extended attributes
       - Inode unlinked state
       - Directories
       - Symbolic links
       - AGI's unlinked inode list.
       - Parent pointers.
     - Move Orphan files to lost and found directory.
     - Fixes for Inode repair functionality.
     - Introduce a new sub-AG FITRIM implementation to reduce the duration for
       which the AGF lock is held.
     - Updates for the design documentation.
     - Use Parent Pointers to assist in checking directories, parent pointers,
       extended attributes, and link counts.
 
   * Bring back delalloc support for realtime devices which have an extent size
     that is equal to filesystem's block size.
 
   * Improve performance of log incompat feature handling.
 
   * Fixes
     - Prevent userspace from reading invalid file data due to incorrect.
       updation of file size when performing a non-atomic clone operation.
     - Minor fixes to online repair.
     - Fix confusing return values from xfs_bmapi_write().
     - Fix an out of bounds access due to incorrect h_size during log recovery.
     - Defer upgrading the extent counters in xfs_reflink_end_cow_extent() until
       we know we are going to modify the extent mapping.
     - Remove racy access to if_bytes check in xfs_reflink_end_cow_extent().
     - Fix sparse warnings.
 
   * Cleanups

Pull xfs updates from Chandan Babu:
 "Online repair feature continues to be expanded. Also, we now support
  delayed allocation for realtime devices which have an extent size that
  is equal to filesystem's block size.

  New code:

   - Introduce Parent Pointer extended attribute for inodes

   - Bring back delalloc support for realtime devices which have an
     extent size that is equal to filesystem's block size

   - Improve performance of log incompat feature handling

  Online Repair:

   - Implement atomic file content exchanges i.e. exchange ranges of
     bytes between two files atomically

   - Create temporary files to repair file-based metadata. This uses
     atomic file content exchange facility to swap file fork mappings
     between the temporary file and the metadata inode

   - Allow callers of directory/xattr code to set an explicit owner
     number to be written into the header fields of any new blocks that
     are created. This is required to avoid walking every block of the
     new structure and modify their ownership during online repair

   - Repair more data structures:
       - Extended attributes
       - Inode unlinked state
       - Directories
       - Symbolic links
       - AGI's unlinked inode list
       - Parent pointers

   - Move Orphan files to lost and found directory

   - Fixes for Inode repair functionality

   - Introduce a new sub-AG FITRIM implementation to reduce the duration
     for which the AGF lock is held

   - Updates for the design documentation

   - Use Parent Pointers to assist in checking directories, parent
     pointers, extended attributes, and link counts

  Fixes:

   - Prevent userspace from reading invalid file data due to incorrect.
     updation of file size when performing a non-atomic clone operation

   - Minor fixes to online repair

   - Fix confusing return values from xfs_bmapi_write()

   - Fix an out of bounds access due to incorrect h_size during log
     recovery

   - Defer upgrading the extent counters in xfs_reflink_end_cow_extent()
     until we know we are going to modify the extent mapping

   - Remove racy access to if_bytes check in
     xfs_reflink_end_cow_extent()

   - Fix sparse warnings

  Cleanups:

   - Hold inode locks on all files involved in a rename until the
     completion of the operation. This is in preparation for the parent
     pointers patchset where parent pointers are applied in a separate
     chained update from the actual directory update

   - Compile out v4 support when disabled

   - Cleanup xfs_extent_busy_clear()

   - Remove unused flags and fields from struct xfs_da_args

   - Remove definitions of unused functions

   - Improve extended attribute validation

   - Add higher level directory operations helpers to remove duplication
     of code

   - Cleanup quota (un)reservation interfaces"

Linus Torvalds
d0e71e23ec Revert "fanotify: remove unneeded sub-zero check for unsigned value"
This reverts commit e659522446.

These kinds of patches are only making the code worse.

Compilers don't care about the unnecessary check, but removing it makes
the code less obvious to a human.  The declaration of 'len' is more than
80 lines earlier, so a human won't easily see that 'len' is of an
unsigned type, so to a human the range check that checks against zero is
much more explicit and obvious.

Any tool that complains about a range check like this just because the
variable is unsigned is actively detrimental, and should be ignored.

c9834d848d mailbox: Convert from tasklet to BH workqueue
The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.

The return value of pm_runtime_get_sync() in cmdq_mbox_shutdown()
will return 1 when pm runtime state is active, and we don't want to
get the warning message in this case.

So we change the return value < 0 for WARN_ON().

3f58c1f420 mailbox: omap: Remove kernel FIFO message queuing
The kernel FIFO queue has a couple issues. The biggest issue is that
it causes extra latency in a path that can be used in real-time tasks,
such as communication with real-time remote processors.

The whole FIFO idea itself looks to be a leftover from before the
unified mailbox framework. The current mailbox framework expects
mbox_chan_received_data() to be called with data immediately as it
arrives. Remove the FIFO and pass the messages to the mailbox
framework directly as part of a threaded IRQ handler.

04a07a3441 mailbox: omap: Reverse FIFO busy check logic
It is much more clear to check if the hardware FIFO is full and return
EBUSY if true. This allows us to also remove one level of indention
from the core of this function. It also makes the similarities between
omap_mbox_chan_send_noirq() and omap_mbox_chan_send() more obvious.

5aa00b68ea mailbox: omap: Remove mbox_chan_to_omap_mbox()
This function only checks if mbox_chan *chan is not NULL, but that cannot
be the case and if it was returning NULL which is not later checked
doesn't save us from this. The second check for chan->con_priv is
completely redundant as if it was NULL we would return NULL just the
same. Simply dereference con_priv directly and remove this function.
