Currently, when a controller is configured to use filtered mode, thermal
readings are valid only about 30% of the time.
Upon testing, it was noticed that lowering any of the interval settings
resulted in an improved rate of valid data. The same was observed when
decreasing the number of samples for each sensor (which also results in
quicker measurements).
Retrying the read with a timeout longer than the time it takes to
resample (about 344us with these settings and 4 sensors) also improves
the rate.
Lower all timing settings to the minimum, configure the filtering to
single sample, and poll the measurement register for at least one period
to improve the data validity on filtered mode. With these changes in
place, out of 100000 reads, a single one failed, ie 99.999% of the data
was valid.

The sun8i thermal driver reads calibration data via the nvmem API at
startup, updating the device configuration and not referencing the data
again. Rather than explicitly freeing the nvmem data the driver relies
on devm_ to release it, even though the data is never referenced again.
The allocation is still tracked so it's not leaked but this is notable
when looking at the code and is a little wasteful so let's instead
explicitly free the nvmem after we're done with it.

Each LVTS thermal controller can have up to four sensors, each capable
of triggering its own interrupt when its measured temperature crosses
the configured threshold. The threshold for each sensor is handled
separately by the thermal framework, since each one is registered with
its own thermal zone and trips. However, the temperature thresholds are
configured on the controller, and therefore are shared between all
sensors on that controller.
When the temperature measured by the sensors is different enough to
cause the thermal framework to configure different thresholds for each
one, interrupts start triggering on sensors outside the last threshold
configured.
To address the issue, track the thresholds required by each sensor and
only actually set the highest one in the hardware, and disable
interrupts for all sensors outside the current configured range.

The thermal framework might leave the low threshold unset if there
aren't any lower trip points. This leaves the register zeroed, which
translates to a very high temperature for the low threshold. The
interrupt for this threshold is then immediately triggered, and the
state machine gets stuck, preventing any other temperature monitoring
interrupts to ever trigger.
(The same happens by not setting the Cold or Hot to Normal thresholds
when using those)
Set the unused threshold to a valid low value. This value was chosen so
that for any valid golden temperature read from the efuse, when the
value is converted to raw and back again to milliCelsius, the result
doesn't underflow.

Out of the many interrupts supported by the hardware, the only ones of
interest to the driver currently are:
* The temperature went over the high offset threshold, for any of the
sensors
* The temperature went below the low offset threshold, for any of the
sensors
* The temperature went over the stage3 threshold
These are the only thresholds configured by the driver through the
OFFSETH, OFFSETL, and PROTTC registers, respectively.
The current interrupt mask in LVTS_MONINT_CONF, enables many more
interrupts, including data ready on sensors for both filtered and
immediate mode. These are not only not handled by the driver, but they
are also triggered too often, causing unneeded overhead. Disable these
unnecessary interrupts.
The meaning of each bit can be seen in the comment describing
LVTS_MONINTST in the IRQ handler.

There are two kinds of temperature monitoring interrupts available:
* High Offset, Low Offset
* Hot, Hot to normal, Cold
The code currently uses the hot/h2n/cold interrupts, however in a way
that doesn't work: the cold threshold is left uninitialized, which
prevents the other thresholds from ever triggering, and the h2n
interrupt is used as the lower threshold, which prevents the hot
interrupt from triggering again after the thresholds are updated by the
thermal framework, since a hot interrupt can only trigger again after
the hot to normal interrupt has been triggered.
But better yet than addressing those issues, is to use the high/low
offset interrupts instead. This way only two thresholds need to be
managed, which have a simpler state machine, making them a better match
to the thermal framework's high and low thresholds.

Each controller can be configured to operate on immediate or filtered
mode. On filtered mode, the sensors are enabled by setting the
corresponding bits in MONCTL0, while on immediate mode, by setting
MSRCTL1.
Previously, the code would set MSRCTL1 for all four sensors when
configured to immediate mode, but given that the controller might not
have all four sensors connected, this would cause interrupts to trigger
for non-existent sensors. Fix this by handling the MSRCTL1 register
analogously to the MONCTL0: only enable the sensors that were declared.

There is a single IRQ handler for each LVTS thermal domain, and it is
supposed to check each of its underlying controllers for the origin of
the interrupt and clear its status. However due to a typo, only the
first controller was ever being handled, which resulted in the interrupt
never being cleared when it happened on the other controllers. Add the
missing index so interrupts are handled for all controllers.

`rustc` outputs by default the temporary files (i.e. the ones saved
by `-Csave-temps`, such as `*.rcgu*` files) in the current working
directory when `-o` and `--out-dir` are not given (even if
`--emit=x=path` is given, i.e. it does not use those for temporaries).
Since out-of-tree modules are compiled from the `linux` tree,
`rustc` then tries to create them there, which may not be accessible.
Thus pass `--out-dir` explicitly, even if it is just for the temporary
files.
Similarly, do so for Rust host programs too.

Pull smb client fix from Steve French:
"Add minor debugging improvement.
The change improves ability to read a network trace to debug problems
on encrypted connections which are very common (e.g. using wireshark
or tcpdump).
That works today with tools like 'smbinfo keys /mnt/file' but requires
passing in a filename on the mount (see e.g. [1]), but it often makes
more sense to just pass in the mount point path (ie a directory not a
filename).
So this fix was needed to debug some types of problems (an obvious
example is on an encrypted connection failing operations on an empty
share or with no files in the root of the directory) - so you can
simply pass in the 'smbinfo keys <mntpoint>' and get the information
that wireshark needs"

During allocations, while looking for preallocations(PA) in the per
inode rbtree, we can't do a direct traversal of the tree because
ext4_mb_discard_group_preallocation() can paralelly mark the pa deleted
and that can cause direct traversal to skip some entries. This was
leading to a BUG_ON() being hit [1] when we missed a PA that could satisfy
our request and ultimately tried to create a new PA that would overlap
with the missed one.
To makes sure we handle that case while still keeping the performance of
the rbtree, we make use of the fact that the only pa that could possibly
overlap the original goal start is the one that satisfies the below
conditions:
1. It must have it's logical start immediately to the left of
(ie less than) original logical start.
2. It must not be deleted
To find this pa we use the following traversal method:
1. Descend into the rbtree normally to find the immediate neighboring
PA. Here we keep descending irrespective of if the PA is deleted or if
it overlaps with our request etc. The goal is to find an immediately
adjacent PA.
2. If the found PA is on right of original goal, use rb_prev() to find
the left adjacent PA.
3. Check if this PA is deleted and keep moving left with rb_prev() until
a non deleted PA is found.
4. This is the PA we are looking for. Now we can check if it can satisfy
the original request and proceed accordingly.
This approach also takes care of having deleted PAs in the tree.
(While we are at it, also fix a possible overflow bug in calculating the
end of a PA)

In ext4_mb_choose_next_group_best_avail(), we want the start order to be
1 less than goal length and the min_order to be, at max, 1 more than the
original length. This commit fixes an off by one issue that arose due to
the fact that 1 << fls(n) > (n).
After all the processing:
order = 1 order below goal len
min_order = maximum of the three:-
- order - trim_order
- 1 order below B2C(s_stripe)
- 1 order above original len

When run on a file system where the inline_data feature has been
enabled, xfstests generic/269, generic/270, and generic/476 cause ext4
to emit error messages indicating that inline directory entries are
corrupted. This occurs because the inline offset used to locate
inline directory entries in the inode body is not updated when an
xattr in that shared region is deleted and the region is shifted in
memory to recover the space it occupied. If the deleted xattr precedes
the system.data attribute, which points to the inline directory entries,
that attribute will be moved further up in the region. The inline
offset continues to point to whatever is located in system.data's former
location, with unfortunate effects when used to access directory entries
or (presumably) inline data in the inode body.

Dumping the enc/dec keys is a session wide operation.
And it should not matter if the ioctl was run on
a regular file or a directory.
Currently, we obtain the tcon pointer from the
cifs file handle. But since there's no dir open call
in cifs, this is not populated for dirs.
This change allows dumping of session keys using ioctl
even for directories. To do this, we'll now get the
tcon pointer from the superblock, and not from the file
handle.

Pull devicetree fixes from Rob Herring:
- Fix moortec,mr75203 schema usage of 'multipleOf' keyword
- Fix regression in systems depending on "of-display" device name
- Build fix for s390 with CONFIG_PCI=n and OF_EARLY_FLATTREE=y
- Drop two obsolete serial .txt bindings
* tag 'devicetree-fixes-for-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
dt-bindings: serial: Remove obsolete nxp,lpc1850-uart.txt
dt-bindings: serial: Remove obsolete cavium-uart.txt
dt-bindings: hwmon: moortec,mr75203: fix multipleOf for coefficients
of: Preserve "of-display" device name for compatibility
of: make OF_EARLY_FLATTREE depend on HAS_IOMEM
Three fixes here:
- The issues with accounting for register and padding length on raw
buses turn out to be quite widespread in custom buses, in order to
avoid disturbing anything drop the initial fixes and fall back to
a point fix in the SMBus code where the issue was originally noticed,
a more substantial refactoring of the API which ensures that all
buses make the same assumptions will follow.
- The generic regcache code had been forcing on async I/O which did
not work with the new maple tree sync code when used with SPI. Since
that was mainly for the rbtree cache and the assumptions about hardware
that drove the choice are probably not true any more fix this by pushing
the enablement of async down into the rbtree code, probably this also
makes cache syncs for systems faster though it's not the point.
- The test code was triggering use of the rbtree and maple tree caches
with dynamic allocation of nodes since all the testing is with RAM
backed caches with no I/O performance issues. Just disable the
locking in the tests to avoid triggering warnings when allocation
debugging is turned on, it's not really what's being tested.
