The 512B buffer sector_buf field of struct ata_port is used for scanning
devices as well as during error recovery with ata EH. This buffer is
thus useless if a port does not have a device connected to it.
And also given that commands using this buffer are issued to devices,
and not to ports, move this buffer definition from struct ata_port to
struct ata_device.
This change slightly increases system memory usage for systems using a
port-multiplier as in that case we do not need a per-device buffer for
scanning devices (PMP does not allow parallel scanning) nor for EH (as
when entering EH we are guaranteed that all commands to all devices
connected to the PMP have completed or have been aborted). However,
this change reduces memory usage on systems that have many ports with
only few devices rives connected, which is a much more common use case
than the PMP use case.

The function ata_eh_read_sense_success_ncq_log() does more that just
reading the sense data for successful NCQ commands log page as it also
sets the sense data for all commands listed in the log page.
Rename this function to ata_eh_get_ncq_success_sense() to better
describe what the function does. Furthermore, since this function is
only called from ata_eh_get_success_sense() in libata-eh.c, there is no
need to export it and its declaration can be moved to
drivers/ata/libata.h.
To be consistent with this change, the function
ata_eh_read_sense_success_non_ncq() is also renamed to
ata_eh_get_non_ncq_success_sense().

Unlike ata_std_prereset() and ata_std_postreset(), the function
sata_std_hardreset() applies only to SATA devices, as its name implies.
So move its definition to libata-sata.c.
Together with this, also move the definition of sata_port_ops to
libata-sata.c, where it belongs.

A regular page read consist in:
- Asking one page of content from the NAND array to be loaded in the
chip's SRAM,
- Waiting for the operation to be done,
- Retrieving the data (I/O phase) from the chip's SRAM.
When reading several sequential pages, the above operation is repeated
over and over. There is however a way to optimize these accesses, by
enabling continuous reads. The feature requires the NAND chip to have a
second internal SRAM area plus a bit of additional internal logic to
trigger another internal transfer between the NAND array and the second
SRAM area while the I/O phase is ongoing. Once the first I/O phase is
done, the host can continue reading more data, continuously, as the chip
will automatically switch to the second SRAM content (which has already
been loaded) and in turns trigger the next load into the first SRAM area
again.
From an instruction perspective, the command op-codes are different, but
the same cycles are required. The only difference is that after a
continuous read (which is stopped by a CS deassert), the host must
observe a delay of tRST. However, because there is no guarantee in Linux
regarding the actual state of the CS pin after a transfer (in order to
speed-up the next transfer if targeting the same device), it was
necessary to manually end the continuous read with a configuration
register write operation.
Continuous reads have two main drawbacks:
* They only work on full pages (column address ignored)
* Only the main data area is pulled, out-of-band bytes are not
accessible. Said otherwise, the feature can only be useful with on-die
ECC engines.
Performance wise, measures have been performed on a Zynq platform using
Macronix SPI-NAND controller with a Macronix chip (based on the
flash_speed tool modified for testing sequential reads):
- 1-1-1 mode: performances improved from +3% (2-pages) up to +10% after
a dozen pages.
- 1-1-4 mode: performances improved from +15% (2-pages) up to +40% after
a dozen pages.
This series is based on a previous work from Macronix engineer Jaime
Liao.

In order to be able to iterate easily across eraseblocks rather than
pages, let's introduce a block iterator inspired from the page iterator.
The main usage of this iterator will be for continuous/sequential reads,
where it is interesting to use a single request rather than split the
requests in smaller chunks (ie. pages) that can be hardly optimized.
So a "continuous" boolean get's added for this purpose.

Currently DFS works under assumption there could be only one channel
context in the hardware. Hence, drivers just calls the function
ieee80211_radar_detected() passing the hardware structure. However, with
MLO, this obviously will not work since number of channel contexts will be
more than one and hence drivers would need to pass the channel information
as well on which the radar is detected.
Also, when radar is detected in one of the links, other link's CAC should
not be cancelled.
Hence, in order to support DFS with MLO, do the following changes -
* Add channel context conf pointer as an argument to the function
ieee80211_radar_detected(). During MLO, drivers would have to pass on
which channel context conf radar is detected. Otherwise, drivers could
just pass NULL.
* ieee80211_radar_detected() will iterate over all channel contexts
present and
* if channel context conf is passed, only mark that as radar
detected
* if NULL is passed, then mark all channel contexts as radar
detected
* Then as usual, schedule the radar detected work.
* In the worker, go over all the contexts again and for all such context
which is marked with radar detected, cancel the ongoing CAC by calling
ieee80211_dfs_cac_cancel() and then notify cfg80211 via
cfg80211_radar_event().
* To cancel the CAC, pass the channel context as well where radar is
detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is
canceled only on the links using the provided context, leaving other
links unaffected.
This would also help in scenarios where there is split phy 5 GHz radio,
which is capable of DFS channels in both lower and upper band. In this
case, simultaneous radars can be detected.

A few members related to DFS handling are currently under per wireless
device data structure. However, in order to support DFS with MLO, there is
a need to have them on a per-link manner.
Hence, as a preliminary step, move members cac_started, cac_start_time
and cac_time_ms to be on a per-link basis.
Since currently, link ID is not known at all places, use default value of

This adds a sample rate definition for 12kHz, 24kHz and 128kHz.
Admittedly, just a few drivers are currently using these sample
rates but there is enough of a recurrence to justify adding a definition
for them and remove some custom rate constraint code while at it.
The new definitions are not added to the interval definitions, such as
SNDRV_PCM_RATE_8000_44100, because it would silently add new supported
rates to drivers that may or may not support them. For sure the drivers
have not been tested for these new rates so it is better to leave them out
of interval definitions.
That being said, the added rates are multiples of well know rates families,
it is very likely that a lot of devices out there actually supports them.

ASoC: Fixes for v6.11
A larger set of fixes than I'd like at this point, but mainly due to
people working on fixing module autoloading by adding missing exports of
ID tables rather than anything particularly concerning. There are some

SOF which ensures that a struct layout doesn't vary depending on the

In commit 6f8b12d661d0 ("net: napi: add hard irqs deferral feature")
napi_defer_irqs was added to net_device and napi_defer_irqs_count was
added to napi_struct, both as type int.
This value never goes below zero, so there is not reason for it to be a
signed int. Change the type for both from int to u32, and add an
overflow check to sysfs to limit the value to S32_MAX.
The limit of S32_MAX was chosen because the practical limit before this
patch was S32_MAX (anything larger was an overflow) and thus there are
no behavioral changes introduced. If the extra bit is needed in the
future, the limit can be raised.
Before this patch:
$ sudo bash -c 'echo 2147483649 > /sys/class/net/eth4/napi_defer_hard_irqs'
$ cat /sys/class/net/eth4/napi_defer_hard_irqs
-2147483647
After this patch:
$ sudo bash -c 'echo 2147483649 > /sys/class/net/eth4/napi_defer_hard_irqs'
bash: line 0: echo: write error: Numerical result out of range
Similarly, /sys/class/net/XXXXX/tx_queue_len is defined as unsigned:
include/linux/netdevice.h: unsigned int tx_queue_len;
And has an overflow check:
dev_change_tx_queue_len(..., unsigned long new_len):
if (new_len != (unsigned int)new_len)
return -ERANGE;

Commit 980ca8ceeae6 ("bpf: check bpf_dummy_struct_ops program params for
test runs") does bitwise AND between reg_type and PTR_MAYBE_NULL, which
is correct, but due to type difference the compiler complains:
net/bpf/bpf_dummy_struct_ops.c:118:31: warning: bitwise operation between different enumeration types ('const enum bpf_reg_type' and 'enum bpf_type_flag') [-Wenum-enum-conversion]
118 | if (info && (info->reg_type & PTR_MAYBE_NULL))
| ~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~
Workaround the warning by moving the type_may_be_null() helper from
verifier.c into bpf_verifier.h, and reuse it here to check whether param
is nullable.

str_enabled_disabled/str_on_off/str_yes_no helpers, we can
add the opposite helpers. That's str_disable_enable,
str_disabled_enabled, str_off_on and str_no_yes.

str_disable_enable now has 3 use cases) exist in the code

Since the WMI driver core now takes care of retrieving the
WMI event data even for legacy WMI notify handlers, this
function is no longer used.
Remove it to prevent WMI drivers from messing up the ACPI

The current legacy WMI handlers are susceptible to picking up wrong
WMI event data on systems where different WMI devices share some
notification IDs.
Prevent this by letting the WMI driver core taking care of retrieving
the event data. This also simplifies the legacy WMI handlers and their
implementation inside the WMI driver core.
