====================
mlx5: Add sensor name in temperature message
This small series from Shahar adds the sensors names to the temperature
event messages, in addition to the existing bitmap indicators.
This improves human readability.
Series starts with simple refactoring and modifications. The top patch
adds the sensors names.

Previously, a temperature event message included a bitmap indicating
which sensors detect high temperatures.
To enhance clarity, we modify the message format to explicitly list
the names of the overheating sensors, alongside the sensors bitmap.
If HWMON is not configured, the event message remains unchanged.

In the sensor_count field of the MTEWE register, bits 1-62 are
supported only for unmanaged switches, not for NICs, and bit 63
is reserved for internal use.
To prevent confusing output that may include set bits that are
not relevant to NIC sensors, we update the bitmask to retain only
the first bit, which corresponds to the sensor ASIC.

This patch adds TR(token ring) manipulations and adds correct
macro names for those magic numbers. TR is a way to access
proprietary registers on page 52b5. Use these helper functions
so we can see which fields we're going to modify/set/clear.
TR functions with __* prefix mean that the operations inside
aren't wrapped by page select/restore functions.
This patch doesn't really change registers' settings but just
enhances readability and maintainability.

The jcore-aic irqchip does not have separate interrupt numbers reserved for
cpu-local vs global interrupts. Therefore the device drivers need to
request the given interrupt as per CPU interrupt.
69a9dcbd2d65 ("clocksource/drivers/jcore: Use request_percpu_irq()")
converted the clocksource driver over to request_percpu_irq(), but failed
to do add all the required changes, resulting in a failure to register PIT
interrupts.
Fix this by:
1) Explicitly mark the interrupt via irq_set_percpu_devid() in
jcore_pit_init().
2) Enable and disable the per CPU interrupt in the CPU hotplug callbacks.
3) Pass the correct per-cpu cookie to the irq handler by using
handle_percpu_devid_irq() instead of handle_percpu_irq() in
handle_jcore_irq().

Christoph reports that their rk3399 system dies since commit 773c05f417fa1
("irqchip/gic-v3: Work around insecure GIC integrations").
It appears that some rk3399 have secure payloads, and that the firmware
sets SCR_EL3.FIQ==1. Obivously, disabling security in that configuration
leads to even more problems.
Revisit the workaround by:
- making it rk3399 specific
- checking whether Group-0 is available, which is a good proxy
for SCR_EL3.FIQ being 0
- either apply the workaround if Group-0 is available, or disable
pseudo-NMIs if not
Note that this doesn't mean that the secure side is able to receive
interrupts, as all interrupts are made non-secure anyway.
Clearly, nobody ever tested secure interrupts on this platform.

Pull vfs fixes from Christian Brauner:
"It was reported that the acct(2) system call can be used to trigger a
NULL deref in cases where it is set to write to a file that triggers
an internal lookup.
This can e.g., happen when pointing acct(2) to /sys/power/resume. At
the point the where the write to this file happens the calling task
has already exited and called exit_fs() but an internal lookup might
be triggered through lookup_bdev(). This may trigger a NULL-deref when
accessing current->fs.
Reorganize the code so that the the final write happens from the
workqueue but with the caller's credentials. This preserves the
(strange) permission model and has almost no regression risk.
Also block access to kernel internal filesystems as well as procfs and
sysfs in the first place.
Various fixes for netfslib:
- Fix a number of read-retry hangs, including:
- Incorrect getting/putting of references on subreqs as we retry
them
- Failure to track whether a last old subrequest in a retried set
is superfluous
- Inconsistency in the usage of wait queues used for subrequests
(ie. using clear_and_wake_up_bit() whilst waiting on a private
waitqueue)
- Add stats counters for retries and publish in /proc/fs/netfs/stats.
This is not a fix per se, but is useful in debugging and shouldn't
otherwise change the operation of the code
- Fix the ordering of queuing subrequests with respect to setting the
request flag that says we've now queued them all"

When a destination client is a user client in the legacy MIDI mode and
it sets the no-UMP-conversion flag, currently the all UMP events are
still passed as-is. But this may confuse the user-space, because the
event packet size is different from the legacy mode.
Since we cannot handle UMP events in user clients unless it's running
in the UMP client mode, we should filter out those events instead of
accepting blindly. This patch addresses it by slightly adjusting the
conditions for UMP event handling at the event delivery time.

Any active plane needs to have its crtc included in the atomic
state. For planes enabled via uapi that is all handler in the core.
But when we use a plane for joiner the uapi code things the plane
is disabled and therefore doesn't have a crtc. So we need to pull
those in by hand. We do it first thing in
intel_joiner_add_affected_crtcs() so that any newly added crtc will
subsequently pull in all of its joined crtcs as well.
The symptoms from failing to do this are:
- duct tape in the form of commit 1d5b09f8daf8 ("drm/i915: Fix NULL
ptr deref by checking new_crtc_state")
- the plane's hw state will get overwritten by the disabled
uapi state if it can't find the uapi counterpart plane in
the atomic state from where it should copy the correct state

When an invalid function ID of an SBI extension is used we should
return not-supported, not invalid-param. Also, when we see that at
least one hartid constructed from the base and mask parameters is
invalid, then we should return invalid-param. Finally, rather than
relying on overflowing a left shift to result in zero and then using
that zero in a condition which [correctly] skips sending an IPI (but
loops unnecessarily), explicitly check for overflow and exit the loop
immediately.

Add locking to `vf610_gpio_direction_input|output()` functions. Without
this locking, a race condition exists between concurrent calls to these
functions, potentially leading to incorrect GPIO direction settings.
To verify the correctness of this fix, a `trylock` patch was applied,
where after a couple of reboots the race was confirmed. I.e., one user
had to wait before acquiring the lock. With this patch the race has not
been encountered. It's worth mentioning that any type of debugging
(printing, tracing, etc.) would "resolve"/hide the issue.

As per the API contract - gpio_chip::get_direction() may fail and return
a negative error number. However, we treat it as if it always returned 0
or 1. Check the return value of the callback and propagate the error

The Inline mode does not use a journal; it makes no sense to print
journal information in DM table. Print it only if the journal is used.
The same applies to interleave_sectors (unused for Inline mode).
Also, add comments for arg_count, as the current calculation
is quite obscure.

In Inline mode, the journal is unused, and journal_sectors is zero.
Calculating the journal watermark requires dividing by journal_sectors,
which should be done only if the journal is configured.
Otherwise, a simple table query (dmsetup table) can cause OOPS.
This bug did not show on some systems, perhaps only due to
compiler optimization.
On my 32-bit testing machine, this reliably crashes with the following:
: Oops: divide error: 0000 [#1] PREEMPT SMP
: CPU: 0 UID: 0 PID: 2450 Comm: dmsetup Not tainted 6.14.0-rc2+ #959

When the user sets a file or directory as read-only (e.g. ~S_IWUGO),
the client will set the ATTR_READONLY attribute by sending an
SMB2_SET_INFO request to the server in cifs_setattr_{,nounix}(), but
cifsInodeInfo::cifsAttrs will be left unchanged as the client will
only update the new file attributes in the next call to
{smb311_posix,cifs}_get_inode_info() with the new metadata filled in
@data parameter.
Commit a18280e7fdea ("smb: cilent: set reparse mount points as
automounts") mistakenly removed the @data NULL check when calling
is_inode_cache_good(), which broke the above case as the new
ATTR_READONLY attribute would end up not being updated on files with a
read lease.
Fix this by updating the inode whenever we have cached metadata in
@data parameter.

Pull driver core api addition from Greg KH:
"Here is a driver core new api for 6.14-rc3 that is being added to
allow platform devices from stop being abused.
It adds a new 'faux_device' structure and bus and api to allow almost
a straight or simpler conversion from platform devices that were not
really a platform device. It also comes with a binding for rust, with
an example driver in rust showing how it's used.
I'm adding this now so that the patches that convert the different
drivers and subsystems can all start flowing into linux-next now
through their different development trees, in time for 6.15-rc1.
We have a number that are already reviewed and tested, but adding
those conversions now doesn't seem right. For now, no one is using
this, and it passes all build tests from 0-day and linux-next, so all
should be good"
