With the removal of widget setup during BE hw_params, the DAI config IPC
is never sent with the SOF_DAI_CONFIG_FLAGS_HW_PARAMS. This means that
the early bit clock feature required for certain codecs will be broken.
Fix this by saving the config flags sent during BE DAI hw_params and
reusing it when the DAI_CONFIG IPC is sent after the DAI widget is set
up. Also, free the DAI config before the widget is freed.
The DAI_CONFIG IPC sent during the sof_widget_free() does not have the
DAI index information. So, save the dai_index in the config during
hw_params and reuse it during hw_free.
For IPC4, do not clear the node ID during hw_free. It will be needed for
freeing the group_ida during unprepare.

The logic for the ioremap is to find the resource index 3 (IRAM) and
infer the BAR address by subtracting the IRAM offset. The BAR size
defined in hardware specifications is 2MB.
The commit 5947b2726beb6 ("ASoC: SOF: Intel: Check the bar size before
remapping") tried to find the BAR size by querying the resource length
instead of a pre-canned value, but by requesting the size for index 3
it only gets the size of the IRAM. That's obviously wrong and prevents
the probe from proceeding.
This commit attempted to fix an issue in a fuzzing/simulated
environment but created another on actual devices, so the best course
of action is to revert that change.

For some reason the convention for topology names was not followed and
the name inspired by another unrelated hardware configuration. As a

x86 ACPI boards which ship with only Android as their factory image usually
have pretty broken ACPI tables, relying on everything being hardcoded in
the factory kernel image and often disabling parts of the ACPI enumeration
kernel code to avoid the broken tables causing issues.
Part of this broken ACPI code is that sometimes these boards have _AEI
ACPI GPIO event handlers which are broken.
So far this has been dealt with in the platform/x86/x86-android-tablets.c
module, which contains various workarounds for these devices, by it calling
acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to
disable the handlers.
But in some cases this is too late, if the handlers are of the edge type
then gpiolib-acpi.c's code will already have run them at boot.
This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion",
making them unavailable for drivers which actually need them.
Boards with these broken ACPI tables are already listed in
drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration().
Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers()
helper, this re-uses the DMI-ids rather then having to duplicate the same
DMI table in gpiolib-acpi.c .
Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing
boards with troublesome ACPI gpio event handlers, so that the current
acpi_gpiochip_free_interrupts() hack can be removed from
x86-android-tablets.c .

In case that psci_pd_init_topology() fails for some reason,

Customers using GKE 1.25 and 1.26 are facing conntrack issues
root caused to commit c9c3b6811f74 ("netfilter: conntrack: make
max chain length random").
Even if we assume Uniform Hashing, a bucket often reachs 8 chained
items while the load factor of the hash table is smaller than 0.5
With a limit of 16, we reach load factors of 3.
With a limit of 32, we reach load factors of 11.
With a limit of 40, we reach load factors of 15.
With a limit of 50, we reach load factors of 24.
This patch changes MIN_CHAINLEN to 50, to minimize risks.
Ideally, we could in the future add a cushion based on expected
load factor (2 * nf_conntrack_max / nf_conntrack_buckets),
because some setups might expect unusual values.

My randconfig build setup ran into another kallsyms warning:
Inconsistent kallsyms data
Try make KALLSYMS_EXTRA_PASS=1 as a workaround
After adding some debugging code to kallsyms.c, I saw that the recently
added kallsyms_seqs_of_names symbol can sometimes cause the second stage
table to be slightly longer than the first stage, which makes the
build inconsistent.
Add it to the exception table that contains all other kallsyms-generated
symbols.

Looks like a braino that used to be fixed in e.g. #next.alpha
had gotten into alpha.git cherry-picked version of that patch.
Sure, alpha has no preempt, but preempt_enable() in place of
preempt_disable() is actively confusing the readers...
Other than that, the cherry-picked variant matches what I have.

TEST_GEN_FILES but now with TEST_FILES to avoid having them deleted
when doing a clean. Also fix the way the architecture is being
determined as they should also be installed when ARCH=x86_64 is
provided explicitly. Then also append extra files to TEST_FILES and

Backport the relevant part of upstream commit 5b266196 [0].
This fixes in-place decompression for x86-64 kernel decompression. It
uses a bound of 131072 + (uncompressed_size >> 8), which can be violated
after upstream commit 6a7ede3d [1], as zstd can use part of the output
buffer as temporary storage, and without this patch needs a bound of
~262144.
The fix is for zstd to detect that the input and output buffers overlap,
so that zstd knows it can't use the overlapping portion of the output
buffer as tempoary storage. If the margin is not large enough, this will
ensure that zstd will fail the decompression, rather than overwriting
part of the input data, and causing corruption.
This fix has been landed upstream and is in release v1.5.4. That commit
also adds unit and fuzz tests to verify that the margin we use is
respected, and correct. That means that the fix is well tested upstream.
I have not been able to reproduce the potential bug in x86-64 kernel
decompression locally, nor have I recieved reports of failures to
decompress the kernel. It is possible that compression saves enough
space to make it very hard for the issue to appear.
I've boot tested the zstd compressed kernel on x86-64 and i386 with this
patch, which uses in-place decompression, and sanity tested zstd compression
in btrfs / squashfs to make sure that we don't see any issues, but other
uses of zstd shouldn't be affected, because they don't use in-place
decompression.
Thanks to Vasily Gorbik <gor@linux.ibm.com> for debugging a related issue
on s390, which was triggered by the same commit, but was a bug in how
__decompress() was called [2]. And to Sasha Levin <sashal@kernel.org>

When the sd driver revalidates host-managed SMR disks, it calls
disk_set_zoned() which changes the zone_write_granularity attribute value
to the logical block size regardless of the device type. After that, the sd
driver overwrites the value in sd_zbc_read_zone() with the physical block
size, since ZBC/ZAC requires this for host-managed disks. Between the calls
to disk_set_zoned() and sd_zbc_read_zone(), there exists a window where the
attribute shows the logical block size as the zone_write_granularity value,
which is wrong for host-managed disks. The duration of the window is from
20ms to 200ms, depending on report zone command execution time.
To avoid the wrong zone_write_granularity value between disk_set_zoned()
and sd_zbc_read_zone(), modify the value not in sd_zbc_read_zone() but
just after disk_set_zoned() call.

Hyper-V uses a VHD or VHDX file on the host as the underlying storage for a
virtual disk. The VHD/VHDX file format is a sparse format where real disk
space on the host is assigned in chunks that the VHD/VHDX file format calls
the BlockSize. This BlockSize is not to be confused with the 512-byte (or
4096-byte) sector size of the underlying storage device. The default block
size for a new VHD/VHDX file is 32 Mbytes. When a guest VM touches any
disk space within a 32 Mbyte chunk of the VHD/VHDX file, Hyper-V allocates
32 Mbytes of real disk space for that section of the VHD/VHDX. Similarly,
if a discard operation is done that covers an entire 32 Mbyte chunk,
Hyper-V will free the real disk space for that portion of the VHD/VHDX.
This BlockSize is surfaced in Linux as the "discard_granularity" in
/sys/block/sd<x>/queue, which makes sense.
Hyper-V also has differencing disks that can overlay a VHD/VHDX file to
capture changes to the VHD/VHDX while preserving the original VHD/VHDX.
One example of this differencing functionality is for VM snapshots. When a
snapshot is created, a differencing disk is created. If the snapshot is
rolled back, Hyper-V can just delete the differencing disk, and the VM will
see the original disk contents at the time the snapshot was taken.
Differencing disks are used in other scenarios as well.
The BlockSize for a differencing disk defaults to 2 Mbytes, not 32 Mbytes.
The smaller default is used because changes to differencing disks are
typically scattered all over, and Hyper-V doesn't want to allocate 32
Mbytes of real disk space for a stray write here or there. The smaller
BlockSize provides more efficient use of real disk space.
When a differencing disk is added to a VHD/VHDX, Hyper-V reports
UNIT_ATTENTION with a sense code indicating "Operating parameters have
changed", because the value of discard_granularity should be changed to 2
Mbytes. When the differencing disk is removed, discard_granularity should
be changed back to 32 Mbytes. However, current code simply reports a
message from scsi_report_sense() and the value of
/sys/block/sd<x>/queue/discard_granularity is not updated. The message
isn't very actionable by a sysadmin.
Fix this by having the storvsc driver check for the sense code indicating
that the underly VHD/VHDX block size has changed, and do a rescan of the
device to pick up the new discard_granularity. With this change the entire
transition to/from differencing disks is handled automatically and
transparently, with no confusing messages being output.

In kdump kernel mode, the driver works in reduced functionality mode with
some features disabled such as reduced MSI-X count and RDPQ disabled, etc.
However, the firmware is not aware of this mode in some cases, which
results in undefined behavior.
To address this, the driver informs the firmware about the kdump mode
through MPI capabilities bit during driver initialization. This allows
firmware to adjust its behavior accordingly.

The firmware only supports Logical Disk IDs up to 240 and LD ID 255 (0xFF)
is reserved for deleted LDs. However, in some cases, firmware was assigning
LD ID 254 (0xFE) to deleted LDs and this was causing the driver to mark the
wrong disk as deleted. This in turn caused the wrong disk device to be
taken offline by the SCSI midlayer.
To address this issue, limit the LD ID range from 255 to 240. This ensures
the deleted LD ID is properly identified and removed by the driver without
accidently deleting any valid LDs.

When the SAS Transport Layer support is enabled and a device exposed to
the OS by the driver fails INQUIRY commands, the driver frees up the memory
allocated for an internal HBA port data structure. However, in some places,
the reference to the freed memory is not cleared. When the firmware sends
the Device Info change event for the same device again, the freed memory is
accessed and that leads to memory corruption and OS crash.

iterator variable should not be used after the loop to be more robust for

Linus proposed to avoid any use of the list iterator variable after the
