The 'buffer' local array is used to push data to user space from a
triggered buffer, but it does not set values for inactive channels, as
it only uses iio_for_each_active_channel() to assign new values.
Initialize the array to zero before using it to avoid pushing
uninitialized information to userspace.

Modify ad4695_buffer_preenable() by adding an extra SPI transfer after
each data read to help ensure that the timing requirement between the
last SCLK rising edge and the next CNV rising edge is met. This requires
a restructure of the buf_read_xfer array in ad4695_state. Also define
AD4695_T_SCK_CNV_DELAY_NS to use for each added transfer. Without this
change it is possible for the data to become corrupted on sequential
buffered reads due to the device not properly exiting conversion mode.
Similarly, make adjustments to ad4695_read_one_sample() so that timings
are respected, and clean up the function slightly in the process.

When during a measurement two channels are enabled, two measurements are
done that are reported sequencially in the DATA register. As the code
triggered by reading one of the sysfs properties expects that only one
channel is enabled it only reads the first data set which might or might
not belong to the intended channel.
To prevent this situation disable all channels during probe. This fixes
a problem in practise because the reset default for channel 0 is
enabled. So all measurements before the first measurement on channel 0
(which disables channel 0 at the end) might report wrong values.

User Perspective:
When a user sets the phase value, the ad9832_write_phase() is called.
The phase register has a 12-bit resolution, so the valid range is 0 to
4095. If the phase offset value of 4096 is input, it effectively exactly
equals 0 in the lower 12 bits, meaning no offset.
Reasons for the Change:
1) Original Condition (phase > BIT(AD9832_PHASE_BITS)):
This condition allows a phase value equal to 2^12, which is 4096.
However, this value exceeds the valid 12-bit range, as the maximum valid
phase value should be 4095.
2) Modified Condition (phase >= BIT(AD9832_PHASE_BITS)):
Ensures that the phase value is within the valid range, preventing
invalid datafrom being written.
Impact on Subsequent Logic: st->data = cpu_to_be16(addr | phase):
If the phase value is 2^12, i.e., 4096 (0001 0000 0000 0000), and addr
is AD9832_REG_PHASE0 (1100 0000 0000 0000), then addr | phase results in
1101 0000 0000 0000, occupying DB12. According to the section of WRITING
TO A PHASE REGISTER in the datasheet, the MSB 12 PHASE0 bits should be
DB11. The original condition leads to incorrect DB12 usage, which
contradicts the datasheet and could pose potential issues for future
updates if DB12 is used in such related cases.

If the FW log context memory is retained after FW reset, the existing
code is not handling the condition correctly and zeroes out the data
structures. This potentially will cause a division by zero crash
when the user runs ethtool -w. The last_type is also not set
correctly when the context memory is retained. This will cause errors
because the last_type signals to the FW that all context memory types
have been configured.

The existing code is using RSS profile to determine IPV4/IPV6 GSO type
on all chips older than 5760X. This won't work on 5750X chips that may
be using modified RSS profiles. This commit from 2018 has updated the
driver to not use RSS profile for HW GRO packets on newer chips:
50f011b63d8c ("bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.")
However, a recent commit to add support for the newest 5760X chip broke
the logic. If the GRO packet needs to be re-segmented by the stack, the
wrong GSO type will cause the packet to be dropped.
Fix it to only use RSS profile to determine GSO type on the oldest
5730X/5740X chips which cannot use the new method and is safe to use the
RSS profiles.
Also fix the L3/L4 hash type for RX packets by not using the RSS
profile for the same reason. Use the ITYPE field in the RX completion
to determine L3/L4 hash types correctly.

- Fix zone_dma_limit calculation when RAM starts below 4GB and
ZONE_DMA is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a

For historical reasons, the legacy decompressor code on various
architectures supports 7 different compression types for the compressed
kernel image.
EFI zboot is not a compression library museum, and so the options can be
limited to what is likely to be useful in practice:
- GZIP is tried and tested, and is still one of the fastest at
decompression time, although the compression ratio is not very high;
moreover, Fedora is already shipping EFI zboot kernels for arm64 that
use GZIP, and QEMU implements direct support for it when booting a
kernel without firmware loaded;
- ZSTD has a very high compression ratio (although not the highest), and
is almost as fast as GZIP at decompression time.
Reducing the number of options makes it less of a hassle for other
consumers of the EFI zboot format (such as QEMU today, and kexec in the
future) to support it transparently without having to carry 7 different
decompression libraries.

The platform device named "rzg2l-usb-vbus-regulator", allocated by
the rzg2l-usbphy-ctrl driver, is used to instantiate a regulator driver.
This regulator driver is associated with a device tree (DT) node, which
is a child of the rzg2l-usbphy-ctrl DT node. The regulator's DT node allows
consumer nodes to reference the regulator and configure the regulator as
needed.
Starting with commit cd7a38c40b23 ("regulator: core: do not silently ignore
provided init_data") the struct regulator_dev::dev::of_node is no longer
populated using of_node_get(config->of_node) if the regulator does not
provide init_data. Since the rzg2l-usb-vbus-regulator does not provide
init_data, this behaviour causes the of_find_regulator_by_node() function
to fails, resulting in errors when attempting to request the regulator.
To fix this issue, call device_set_of_node_from_dev() for the
"rzg2l-usb-vbus-regulator" platform device.

Commit
5944ce092b97 ("arch_topology: Build cacheinfo from primary CPU")
adds functionality that architectures can use to optionally allocate and
build cacheinfo early during boot. Commit
6539cffa9495 ("cacheinfo: Add arch specific early level initializer")
lets secondary CPUs correct (and reallocate memory) cacheinfo data if
needed.
If the early build functionality is not used and cacheinfo does not need
correction, memory for cacheinfo is never allocated. x86 does not use
the early build functionality. Consequently, during the cacheinfo CPU
hotplug callback, last_level_cache_is_valid() attempts to dereference
a NULL pointer:
BUG: kernel NULL pointer dereference, address: 0000000000000100
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not present page
PGD 0 P4D 0
Oops: 0000 [#1] PREEPMT SMP NOPTI
CPU: 0 PID 19 Comm: cpuhp/0 Not tainted 6.4.0-rc2 #1
RIP: 0010: last_level_cache_is_valid+0x95/0xe0a
Allocate memory for cacheinfo during the cacheinfo CPU hotplug callback
if not done earlier.
Moreover, before determining the validity of the last-level cache info,
ensure that it has been allocated. Simply checking for non-zero
cache_leaves() is not sufficient, as some architectures (e.g., Intel
processors) have non-zero cache_leaves() before allocation.
Dereferencing NULL cacheinfo can occur in update_per_cpu_data_slice_size().
This function iterates over all online CPUs. However, a CPU may have come
online recently, but its cacheinfo may not have been allocated yet.
While here, remove an unnecessary indentation in allocate_cache_info().

Commit 7c7e6c8924e7 ("tty: serial: handle HAS_IOPORT dependencies")
triggers warning backtraces on a number of platforms which don't support
IO ports.
WARNING: CPU: 0 PID: 0 at drivers/tty/serial/8250/8250_port.c:470 serial8250_set_defaults+0x148/0x1d8
Unsupported UART type 0
The problem is seen because serial8250_set_defaults() is called for
all members of the serial8250_ports[] array even if that array is
not initialized.
Work around the problem by only displaying the warning if the port
type is not 0 (UPIO_PORT) or if iobase is set for the port.

In the function yas537_measure() there is a clamp_val() with limits of
-BIT(13) and BIT(13) - 1. The input clamp value h[] is of type s32. The
BIT() is of type unsigned long integer due to its define in
include/vdso/bits.h. The lower limit -BIT(13) is recognized as -8192 but
expressed as an unsigned long integer. The size of an unsigned long
integer differs between 32-bit and 64-bit architectures. Converting this
to type s32 may lead to undesired behavior.
Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned
long integer divisor BIT(13) causes an unsigned division, shifting the
left-hand side of the equation back and forth, possibly ending up in large
positive values instead of negative values on 32-bit architectures.
To solve those two issues, declare a signed integer with a value of
BIT(13).
There is another omission in the clamp line: clamp_val() returns a value
and it's going nowhere here. Self-assign it to h[i] to make use of the
clamp macro.
Finally, replace clamp_val() macro by clamp() because after changing the
limits from type unsigned long integer to signed integer it's fine that
way.

The dr_domain_add_vport_cap() function generally returns NULL on error
but sometimes we want it to return ERR_PTR(-EBUSY) so the caller can
retry. The problem here is that "ret" can be either -EBUSY or -ENOMEM
and if it's and -ENOMEM then the error pointer is propogated back and
eventually dereferenced in dr_ste_v0_build_src_gvmi_qpn_tag().

The SVM DMA device map direction should be set the same as
the DMA unmap setting, otherwise the DMA core will report
the following warning.
Before finialize this solution, there're some discussion on
the DMA mapping type(stream-based or coherent) in this KFD
migration case, followed by https://lore.kernel.org/all/04d4ab32
-45a1-4b88-86ee-fb0f35a0ca40@amd.com/T/.
As there's no dma_sync_single_for_*() in the DMA buffer accessed
that because this migration operation should be sync properly and
automatically. Give that there's might not be a performance problem
in various cache sync policy of DMA sync. Therefore, in order to
simplify the DMA direction setting alignment, let's set the DMA map
direction as BIDIRECTIONAL.

Set the default workload type to bootup type on smu v13.0.7.
This is because of the constraint on smu v13.0.7.
Gfx activity has an even higher set point on 3D fullscreen
mode than the one on bootup mode. This causes the 3D fullscreen
mode's performance is worse than the bootup mode's performance
for the lightweighted/medium workload. For the high workload,
the performance is the same between 3D fullscreen mode and bootup
mode.
v2: set the default workload in ASIC specific file

Align the page tracking maximum message size with the device's
capability instead of relying on PAGE_SIZE.
This adjustment resolves a mismatch on systems where PAGE_SIZE is 64K,
but the firmware only supports a maximum message size of 4K.
Now that we rely on the device's capability for max_message_size, we
must account for potential future increases in its value.
Key considerations include:
- Supporting message sizes that exceed a single system page (e.g., an 8K
message on a 4K system).
- Ensuring the RQ size is adjusted to accommodate at least 4
WQEs/messages, in line with the device specification.
The above has been addressed as part of the patch.

On the Raspberry Pi 5, performance counters are not being cleared
when `v3d_perfmon_start()` is called, even though we write to the
CLR register. As a result, their values accumulate until they
overflow.
The expected behavior is for performance counters to reset to zero
at the start of a job. When the job finishes and the perfmon is
stopped, the counters should accurately reflect the values for that
specific job.
To ensure this behavior, the performance counters are now enabled
before being cleared. This allows the CLR register to function as
intended, zeroing the counter values when the job begins.

Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before
deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's
PM callbacks. And the motivation is to drain inflight IOs before suspending.
block layer's queue freeze looks very handy, but it is also easy to cause
deadlock, such as, any attempt to call into bio_queue_enter() may run into
deadlock if the queue is frozen in current context. There are all kinds
of ->suspend() called in suspend context, so keeping queue frozen in the
whole suspend context isn't one good idea. And Marek reported lockdep
warning[1] caused by virtio-blk's freeze queue in virtblk_freeze().
[1] https://lore.kernel.org/linux-block/ca16370e-d646-4eee-b9cc-87277c89c43c@samsung.com/
Given the motivation is to drain in-flight IOs, it can be done by calling
freeze & unfreeze, meantime restore to previous behavior by keeping queue
quiesced during suspend.

To verify that Auto Update is possible, the mpfs_auto_update_state()
function performs a "Query Security Service Request" to the system
controller.
Previously, the check was performed on the first element of the
response message, which was accessed using a 32-bit pointer. This
caused the bitwise operation to reference incorrect data, as the
response should be inspected at the byte level. Fixed this by casting
the response to a u8 * pointer, ensuring the check correctly inspects
the appropriate byte of the response message.
Additionally, rename "UL_Auto Update" to "UL_IAP" to match the
PolarFire Family System Services User Guide.
