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
0 for now.

Replace ksz8830 with ksz88x3 for CHIP_ID definition and other
strings. This due to KSZ8830 not being an actual switch but the Chip
ID shared among KSZ8863/8873 switches, impossible to differentiate
from their Chip ID or Revision ID registers.
Now all KSZ*_CHIP_ID macros refer to actual, existing switches which
removes confusion.

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
other runtime fixes and quirks, and a tweak to the ABI definition for
SOF which ensures that a struct layout doesn't vary depending on the
architecture of the host.

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;

With uprobe_unregister() having grown a synchronize_srcu(), it becomes
fairly slow to call. Esp. since both users of this API call it in a
loop.
Peel off the sync_srcu() and do it once, after the loop.
We also need to add uprobe_unregister_sync() into uprobe_register()'s
error handling path, as we need to be careful about returning to the
caller before we have a guarantee that partially attached consumer won't
be called anymore. This is an unlikely slow path and this should be
totally fine to be slow in the case of a failed attach.

uprobe->register_rwsem is one of a few big bottlenecks to scalability of
uprobes, so we need to get rid of it to improve uprobe performance and
multi-CPU scalability.
First, we turn uprobe's consumer list to a typical doubly-linked list
and utilize existing RCU-aware helpers for traversing such lists, as
well as adding and removing elements from it.
For entry uprobes we already have SRCU protection active since before
uprobe lookup. For uretprobe we keep refcount, guaranteeing that uprobe
won't go away from under us, but we add SRCU protection around consumer
list traversal.
Lastly, to keep handler_chain()'s UPROBE_HANDLER_REMOVE handling simple,
we remember whether any removal was requested during handler calls, but
then we double-check the decision under a proper register_rwsem using
consumers' filter callbacks. Handler removal is very rare, so this extra
lock won't hurt performance, overall, but we also avoid the need for any
extra protection (e.g., seqcount locks).

Qualcomm driver updates for v6.12
Support is added for making SCM driver configure the system either for a
full or minimal ramdump following a system crash. The ramdump mode is
changed from being enable-only to enable/disable as requested.
The QSEECOM uefisecapp interface is allow-listed on Surface Laptop 7 and
Lenovo Thinkpad T14s, providing EFI variable access.
The change to match the SMD RPM driver based on the SMD channel name is
reverted, in favor of stepping back to OF-based matching, as a means to
get module autoloading to work properly.
AOSS, APR, ICE, OCMEM, PBS and SMP2P drivers has error handling cleaned
up using scoped resources.
Trace events are added to the BWMON and SMP2P drivers, for better
insights into their operations.
The X1E LLCC configuration data is updated based on recommended values.
A number of platforms are added to the in-kernel PD-mapper.
SocInfo driver is extended with IDs from SM7325, QCS8275 and QCS8300

Now that we provide a unique 64-bit mount ID interface in statx(2), we
can now provide a race-free way for name_to_handle_at(2) to provide a
file handle and corresponding mount without needing to worry about
racing with /proc/mountinfo parsing or having to open a file just to do
statx(2).
While this is not necessary if you are using AT_EMPTY_PATH and don't
care about an extra statx(2) call, users that pass full paths into
name_to_handle_at(2) need to know which mount the file handle comes from
(to make sure they don't try to open_by_handle_at a file handle from a
different filesystem) and switching to AT_EMPTY_PATH would require
allocating a file for every name_to_handle_at(2) call, turning
err = name_to_handle_at(-EBADF, "/foo/bar/baz", &handle, &mntid,
AT_HANDLE_MNT_ID_UNIQUE);
into
int fd = openat(-EBADF, "/foo/bar/baz", O_PATH | O_CLOEXEC);
err1 = name_to_handle_at(fd, "", &handle, &unused_mntid, AT_EMPTY_PATH);
err2 = statx(fd, "", AT_EMPTY_PATH, STATX_MNT_ID_UNIQUE, &statxbuf);
mntid = statxbuf.stx_mnt_id;
close(fd);

Unfortunately, the way we have gone about adding new AT_* flags has
been a little messy. In the beginning, all of the AT_* flags had generic
meanings and so it made sense to share the flag bits indiscriminately.
However, we inevitably ran into syscalls that needed their own
syscall-specific flags. Due to the lack of a planned out policy, we
ended up with the following situations:
* Existing syscalls adding new features tended to use new AT_* bits,
with some effort taken to try to re-use bits for flags that were so
obviously syscall specific that they only make sense for a single
syscall (such as the AT_EACCESS/AT_REMOVEDIR/AT_HANDLE_FID triplet).
Given the constraints of bitflags, this works well in practice, but
ideally (to avoid future confusion) we would plan ahead and define a
set of "per-syscall bits" ahead of time so that when allocating new
bits we don't end up with a complete mish-mash of which bits are
supposed to be per-syscall and which aren't.
* New syscalls dealt with this in several ways:
- Some syscalls (like renameat2(2), move_mount(2), fsopen(2), and
fspick(2)) created their separate own flag spaces that have no
overlap with the AT_* flags. Most of these ended up allocating
their bits sequentually.
In the case of move_mount(2) and fspick(2), several flags have
identical meanings to AT_* flags but were allocated in their own
flag space.
This makes sense for syscalls that will never share AT_* flags, but
for some syscalls this leads to duplication with AT_* flags in a
way that could cause confusion (if renameat2(2) grew a
RENAME_EMPTY_PATH it seems likely that users could mistake it for
AT_EMPTY_PATH since it is an *at(2) syscall).
- Some syscalls unfortunately ended up both creating their own flag
space while also using bits from other flag spaces. The most
obvious example is open_tree(2), where the standard usage ends up
using flags from *THREE* separate flag spaces:
open_tree(AT_FDCWD, "/foo", OPEN_TREE_CLONE|O_CLOEXEC|AT_RECURSIVE);
(Note that O_CLOEXEC is also platform-specific, so several future
OPEN_TREE_* bits are also made unusable in one fell swoop.)
It's not entirely clear to me what the "right" choice is for new
syscalls. Just saying that all future VFS syscalls should use AT_* flags
doesn't seem practical. openat2(2) has RESOLVE_* flags (many of which
don't make much sense to burn generic AT_* flags for) and move_mount(2)
has separate AT_*-like flags for both the source and target so separate
flags are needed anyway (though it seems possible that renameat2(2)
could grow *_EMPTY_PATH flags at some point, and it's a bit of a shame
they can't be reused).
But at least for syscalls that _do_ choose to use AT_* flags, we should
explicitly state the policy that 0x2ff is currently intended for
per-syscall flags and that new flags should err on the side of
overlapping with existing flag bits (so we can extend the scope of
generic flags in the future if necessary).
And add AT_* aliases for the RENAME_* flags to further cement that
renameat2(2) is an *at(2) flag, just with its own per-syscall flags.

We were allowing any users to create a high priority group without any
permission checks. As a result, this was allowing possible denial of
service.
We now only allow the DRM master or users with the CAP_SYS_NICE
capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM.
As the sole user of that uAPI lives in Mesa and hardcode a value of
MEDIUM [1], this should be safe to do.
Additionally, as those checks are performed at the ioctl level,
panthor_group_create now only check for priority level validity.
