If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA. The result
of this change is a large savings in resources for older kernels, and a
cleaner driver configuration for the IRDMA=n case for old and new kernels.
Implement this by avoiding enabling the RDMA capability when scanning
hardware capabilities.
Note: Loading the out-of-tree irdma driver in connection to the in-kernel
ice driver, is not supported, and should not be attempted, especially when
disabling IRDMA in the kernel config.

On E800 series hardware, if the start time for a periodic output signal is
programmed into GLTSYN_TGT_H and GLTSYN_TGT_L registers, the hardware logic
locks up and the periodic output signal never starts. Any future attempt to
reprogram the clock function is futile as the hardware will not reset until
a power on.
The ice_ptp_cfg_perout function has logic to prevent this, as it checks if
the requested start time is in the past. If so, a new start time is
calculated by rounding up.
Since commit d755a7e129a5 ("ice: Cache perout/extts requests and check
flags"), the rounding is done to the nearest multiple of the clock period,
rather than to a full second. This is more accurate, since it ensures the
signal matches the user request precisely.
Unfortunately, there is a race condition with this rounding logic. If the
current time is close to the multiple of the period, we could calculate a
target time that is extremely soon. It takes time for the software to
program the registers, during which time this requested start time could
become a start time in the past. If that happens, the periodic output
signal will lock up.
For large enough periods, or for the logic prior to the mentioned commit,
this is unlikely. However, with the new logic rounding to the period and
with a small enough period, this becomes inevitable.
For example, attempting to enable a 10MHz signal requires a period of 100
nanoseconds. This means in the *best* case, we have 99 nanoseconds to
program the clock output. This is essentially impossible, and thus such a
small period practically guarantees that the clock output function will
lock up.
To fix this, add some slop to the clock time used to check if the start
time is in the past. Because it is not critical that output signals start
immediately, but it *is* critical that we do not brick the function, 0.5
seconds is selected. This does mean that any requested output will be
delayed by at least 0.5 seconds.
This slop is applied before rounding, so that we always round up to the
nearest multiple of the period that is at least 0.5 seconds in the future,
ensuring a minimum of 0.5 seconds to program the clock output registers.
Finally, to ensure that the hardware registers programming the clock output
complete in a timely manner, add a write flush to the end of
ice_ptp_write_perout. This ensures we don't risk any issue with PCIe
transaction batching.
Strictly speaking, this fixes a race condition all the way back at the
initial implementation of periodic output programming, as it is
theoretically possible to trigger this bug even on the old logic when
always rounding to a full second. However, the window is narrow, and the
code has been refactored heavily since then, making a direct backport not
apply cleanly.

net: stmmac: remove unnecessary of_get_phy_mode() calls
This series removes unnecessary of_get_phy_mode() calls from the stmmac
glue drivers. stmmac_probe_config_dt() / devm_stmmac_probe_config_dt()
already gets the interface mode using device_get_phy_mode() and stores
it in plat_dat->phy_interface.
Therefore, glue drivers using of_get_phy_mode() are just duplicating
the work that has already been done.
This series adjusts the glue drivers to remove their usage of
of_get_phy_mode().

sun8i was using of_get_phy_mode() to set plat_dat->mac_interface, which
defaults to plat_dat->phy_interface when the mac-mode DT property is
not present. As nothing in arch/*/boot/dts sets the mac-mode property,
it is highly likely that these two will be identical, and thus there
is no need for this glue driver to set plat_dat->mac_interface.

If vfs_flush() is called with queue frozen, the queue freeze lock may be
connected with FS internal lock, and lockdep warning can be triggered
because the queue freeze lock is connected with too many global or
sub-system locks.
Fix the warning by moving vfs_fsync() out of loop_update_dio():
- vfs_fsync() is only needed when switching to dio
- only loop_change_fd() and loop_configure() may switch from buffered
IO to direct IO, so call vfs_fsync() directly here. This way is safe
because either loop is in unbound, or new file isn't attached
- for the other two cases of set_status and set_block_size, direct IO
can only become off, so no need to call vfs_fsync()

In recent kernels, there are lockdep splats around the
struct request_queue::io_lockdep_map, similar to [1], but they
typically don't show up until reclaim with writeback happens.
Having multiple kernel versions released with a known risc of kernel
deadlock during reclaim writeback should IMHO be addressed and
backported to -stable with the highest priority.
In order to have these lockdep splats show up earlier,
preferrably during system initialization, prime the
struct request_queue::io_lockdep_map as GFP_KERNEL reclaim-
tainted. This will instead lead to lockdep splats looking similar
to [2], but without the need for reclaim + writeback
happening.

With the recent fixes, we can re-enable multi-link
reconfiguration. Also add a CMD() entry to allow
userspace discovery for it.

The mute LED on this HP laptop uses ALC236 and requires a quirk to function.
This patch enables the existing quirk for the device.
Tested on my laptop and the LED behaviour works as intended.

Mixer quicks for the Pioneer DJM-A9 mixer was added in 5289d00 with
additional capture level values added to the common DJM array of values.
This breaks the existing DJM mixers however as alsa-utils relies on
enumeration of the actual mixer options based on the value array which
results in error when storing state.
This commit just separates the A9 values into a separate array and
references them in the corresponding mixer control.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure
groups together all the members of the flexible `struct iwl_tx_cmd`
except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct iwl_tx_cmd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Roll-back to use iwlmvm for those devices. iwlmld will support wifi7
capable devices only. The firmware for the non-wifi7 capable will soon
be frozen and we don't want iwlmld to have to support devices that will
require the old APIs.

tcp_in_quickack_mode() is called from input path for small packets.
It calls __sk_dst_get() which reads sk->sk_dst_cache which has been
put in sock_read_tx group (for good reasons).
Then dst_metric(dst, RTAX_QUICKACK) also needs extra cache line misses.
Cache RTAX_QUICKACK in icsk->icsk_ack.dst_quick_ack to no longer pull
these cache lines for the cases a delayed ACK is scheduled.
After this patch TCP receive path does not longer access sock_read_tx
group.

For 'ti,j7200-cpb-audio' compatible, there is support for only one PLL for
48k. For 11025, 22050, 44100 and 88200 sampling rates, due to absence of
J721E_CLK_PARENT_44100, we get EINVAL while running any audio application.
Add support for these rates by using the 48k parent clock and adjusting
the clock for these rates later in j721e_configure_refclk.
