Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:
struct foo {
int count;
char buf[];
};
struct bar {
int count;
struct foo data[] __counted_by(count);
};
because the size of data cannot be calculated with the standard array
size formula:
sizeof(struct foo) * count
This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the
ports member of 'struct mxser_board' triggers this restriction,
resulting in:
drivers/tty/mxser.c:291:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct mxser_port' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
291 | struct mxser_port ports[] __counted_by(nports);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

An unintended consequence of commit 9c573cd313 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.
The prior intent of the per-architecture limits were:
arm64: capped at 0x1FF (9 bits), 5 bits effective
powerpc: uncapped (10 bits), 6 or 7 bits effective
riscv: uncapped (10 bits), 6 bits effective
x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
s390: capped at 0xFF (8 bits), undocumented effective entropy
Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

When a flexible array structure has a __counted_by annotation, its use
with DEFINE_RAW_FLEX() will result in the count being zero-initialized.
This is expected since one doesn't want to use RAW with a counted_by
struct. Adjust the tests to check for the condition and for compiler
support.

GCC 14.1 complains about the argument usage of kmemdup_array():
drivers/soc/tegra/fuse/fuse-tegra.c:130:65: error: 'kmemdup_array' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
130 | fuse->lookups = kmemdup_array(fuse->soc->lookups, sizeof(*fuse->lookups),
| ^
drivers/soc/tegra/fuse/fuse-tegra.c:130:65: note: earlier argument should specify number of elements, later size of each element
The annotation introduced by commit 7d78a77733 ("string: Add
additional __realloc_size() annotations for "dup" helpers") lets the
compiler think that kmemdup_array() follows the same format as calloc(),
with the number of elements preceding the size of one element. So we
could simply swap the arguments to __realloc_size() to get rid of that
warning, but it seems cleaner to instead have kmemdup_array() follow the
same format as krealloc_array(), memdup_array_user(), calloc() etc.

"A series of fixes that came in since the merge window, the main thing
being the fixes Andy did for DMA sync where we were calling into the
DMA API in suprising ways and causing issues as a result, the main
thing being confusing the IOMMU code.
We've also got some fairly important fixes for the stm32 driver, it
supports a wide range of hardware and some optimisations that were
done recently have broken on some systems, and a fix to prevent
glitched signals on the bus in the cadence driver"

spi: stm32: Don't warn about spurious interrupts
spi: Assign dummy scatterlist to unidirectional transfers
spi: cadence: Ensure data lines set to low during dummy-cycle period
spi: stm32: Revert change that enabled controller before asserting CS
spi: Check if transfer is mapped before calling DMA sync APIs
spi: Don't mark message DMA mapped when no transfer in it is
One fix that came in since -rc1, fixing misuse of a local variable in
the DT parsing code in the RTQ2208 driver.

Intel CPUs have a MSR bit to limit CPUID enumeration to leaf two. If
this bit is set by the BIOS then CPUID evaluation including topology
enumeration does not work correctly as the evaluation code does not try
to analyze any leaf greater than two.
This went unnoticed before because the original topology code just
repeated evaluation several times and managed to overwrite the initial
limited information with the correct one later. The new evaluation code
does it once and therefore ends up with the limited and wrong
information.
Cure this by unlocking CPUID right before evaluating anything which
depends on the maximum CPUID leaf being greater than two instead of
rereading stuff after unlock.
Fixes: 22d63660c3 ("x86/cpu: Use common topology code for Intel")

irq_to_desc() is not exported to loadable modules, so this driver now
fails to link in some configurations:

I can't see a purpose for this call, since the return value is unused
and probably left over from some code refactoring.
Address the link failure by just removing the line.

The prior strscpy() replacement of strncpy() here expected the
manufacture_reply strings to be NUL-terminated, but it is possible
they are not, as the code pattern here shows, e.g., edev->vendor_id
being exactly 1 character larger than manufacture_reply->vendor_id,
and the replaced strncpy() was copying only up to the size of the
source character array. Replace this with memtostr(), which is the
unambiguous way to convert a maybe not-NUL-terminated character array
into a NUL-terminated string.

When running fstest generic/423 with sfu mount option, it
was being skipped due to inability to create sockets:
generic/423 [not run] cifs does not support mknod/mkfifo
which can also be easily reproduced with their af_unix tool:
./src/af_unix /mnt1/socket-two bind: Operation not permitted
Fix sfu mount option to allow creating and reporting sockets.

Commit 7627a0edef ("ata: ahci: Drop low power policy board type")
dropped the board_ahci_low_power board type, and instead enables LPM if:
-The AHCI controller reports that it supports LPM (Partial/Slumber), and
-CONFIG_SATA_MOBILE_LPM_POLICY != 0, and
-The port is not defined as external in the per port PxCMD register, and
-The port is not defined as hotplug capable in the per port PxCMD
register.
Partial and Slumber LPM states can either be initiated by HIPM or DIPM.
For HIPM (host initiated power management) to get enabled, both the AHCI
controller and the drive have to report that they support HIPM.
For DIPM (device initiated power management) to get enabled, only the
drive has to report that it supports DIPM. However, the HBA will reject
device requests to enter LPM states which the HBA does not support.
The problem is that Apacer AS340 drives do not handle low power modes
correctly. The problem was most likely not seen before because no one
had used this drive with a AHCI controller with LPM enabled.
Add a quirk so that we do not enable LPM for this drive, since we see
command timeouts if we do (even though the drive claims to support DIPM).
