6bdafceac1 dt-bindings: pinctrl: qcom: Define common TLMM binding
Several properties are shared between all TLMM bindings. By providing a
common binding to define these properties each platform's binding can be
reduced to just listing which of these properties should be checked for
- or further specified.

9e2fd29864 rtw88: add napi support
Use napi to reduce overhead on rx interrupts.

Driver used to interrupt kernel for every Rx packet, this could
affect both system and network performance. NAPI is a mechanism that
uses polling when processing huge amount of traffic, by doing this
the number of interrupts can be decreased.

Network performance can also benefit from this patch. Since TCP
connection is bidirectional and acks are required for every several
packets. These ack packets occupie the PCI bus bandwidth and could
lead to performance degradation.

When napi is used, GRO receive is enabled by default in the mac80211
stack. So mac80211 won't pass every RX TCP packets to the kernel TCP
network stack immediately. Instead an aggregated large length TCP packet
will be delivered.

This reduces the tx acks sent and gains rx performance. After the patch,
the Rx throughput increases about 25Mbps in 11ac.

3304b6f937 iwlwifi: remove incorrect comment in pnvm
We use this driver as a backport that also runs on older kernels (as
part of the backports project).  So we use some checks to backport or
prevent code from compiling in incompatible kernel version.

When I took one of the PNVM patches from the backport, I accidentally
left the comment that a certain part of the code doesn't work in older
kernels.  This obviously should never be valid for the mainline.
Remove this comment.

b2e37a7114 bpf: Fix subreg optimization for BPF_FETCH
All 32-bit variants of BPF_FETCH (add, and, or, xor, xchg, cmpxchg)
define a 32-bit subreg and thus have zext_dst set. Their encoding,
however, uses dst_reg field as a base register, which causes
opt_subreg_zext_lo32_rnd_hi32() to zero-extend said base register
instead of the one the insn really defines (r0 or src_reg).

Fix by properly choosing a register being defined, similar to how
check_atomic() already does that.

0a76945fd1 ext4: add .kunitconfig fragment to enable ext4-specific tests
As of [1], we no longer want EXT4_KUNIT_TESTS and others to `select`
their deps. This means it can get harder to get all the right things
selected as we gain more tests w/ more deps over time.

This patch (and [2]) proposes we store kunitconfig fragments in-tree to
represent sets of tests. (N.B. right now we only have one ext4 test).

There's still a discussion to be had about how to have a hierarchy of
these files (e.g. if one wanted to test all of fs/, not just fs/ext4).

But this fragment would likely be a leaf node and isn't blocked on
deciding if we want `import` statements and the like.

Usage
=====

Before [2] (on its way to being merged):
  $ cp fs/ext4/.kunitconfig .kunit/
  $ ./tools/testing/kunit/kunit.py run

After [2]:
  $ ./tools/testing/kunit/kunit.py run --kunitconfig=fs/ext4/.kunitconfig

".kunitconfig" vs "kunitconfig"
===============================

See also: commit 14ee5cfd45 ("kunit: Rename 'kunitconfig' to '.kunitconfig'").
* The bit about .gitignore exluding it by default is now a con, however.
* But there are a lot of directories with files that begin with "k" and
  so this could cause some annoyance w/ tab completion*
* This is the name kunit.py expects right now, so some people are used
  to .kunitconfig over "kunitconfig"

Use a new config SOCK_RX_QUEUE_MAPPING to compile-in the socket
RX queue field and logic, instead of the XPS config.
This breaks dependency in XPS, and allows selecting it from non-XPS
use cases, as we do in the next patch.

In addition, use the new flag to wrap the logic in sk_rx_queue_get()
and protect access to the sk_rx_queue_mapping field, while keeping
the function exposed unconditionally, just like sk_rx_queue_set()
and sk_rx_queue_clear().

offload support of SWP in mlx5e_tunnel_features_check() and set features
accordingly, this should be reflected in skb offload requested by the
kernel and we should add the Software Parser offsets only if requested.
Otherwise, in case HW doesn't support SWP for Geneve, data path will

b850bbff96 net/mlx5e: kTLS, Use refcounts to free kTLS RX priv context
wait_for_resync is unreliable - if it timeouts, priv_rx will be freed
anyway. However, mlx5e_ktls_handle_get_psv_completion will be called
sooner or later, leading to use-after-free. For example, it can happen
if a CQ error happened, and ICOSQ stopped, but later on the queues are
destroyed, and ICOSQ is flushed with mlx5e_free_icosq_descs.

This patch converts the lifecycle of priv_rx to fully refcount-based, so
that the struct won't be freed before the refcount goes to zero.

ebf79b6be6 net/mlx5e: Fix CQ params of ICOSQ and async ICOSQ
The commit mentioned below has split the parameters of ICOSQ and async
ICOSQ, but it contained a typo: the CQ parameters were swapped for ICOSQ
and async ICOSQ. Async ICOSQ is longer than the normal ICOSQ, and the CQ
size must be the same as the size of the corresponding SQ, but due to
this bug, the CQ of async ICOSQ was much shorter than async ICOSQ
itself. It led to overflows of the CQ with such messages in dmesg, in
particular, when running multiple kTLS-offloaded streams:

mlx5_core 0000:08:00.0: cq_err_event_notifier:529:(pid 9422): CQ error

4d6e6b0c6d net/mlx5e: Replace synchronize_rcu with synchronize_net
The commit cited below switched from using napi_synchronize to
synchronize_rcu to have a guarantee that it will finish in finite time.
However, on average, synchronize_rcu takes more time than
napi_synchronize. Given that it's called multiple times per channel on
deactivation, it accumulates to a significant amount, which causes
timeouts in some applications (for example, when using bonding with
NetworkManager).

This commit replaces synchronize_rcu with synchronize_net, which is
faster when called under rtnl_lock, allowing to speed up the described
flow.

struct mlx5e_params contains fields ({rx,tx}_cq_moderation) that depend

(MLX5E_PFLAG_{RX,TX}_CQE_BASED_MODER). Whenever the DIM state changes,
mlx5e_reset_{rx,tx}_moderation is called to update the fields, however,
only if the channels are open. The flow where the channels are closed
misses the required update of the fields. This commit moves the calls of
mlx5e_reset_{rx,tx}_moderation, so that they run in both flows.

When mlx5e_ethtool_set_coalesce doesn't change DIM state
(enabled/disabled), it calls mlx5e_set_priv_channels_coalesce

those parameters dynamically (it might even be happening at the same
time).

This patch fixes it by splitting mlx5e_set_priv_channels_coalesce into
two functions (for RX and TX) and calling them only when DIM is disabled
(for RX and TX respectively).

The mptcp subflow route_req() callback performs the subflow
req initialization after the route_req() check. If the latter
fails, mptcp-specific bits of the current request sockets
are left uninitialized.

The above causes bad things at req socket disposal time, when
the mptcp resources are cleared.

This change addresses the issue by splitting subflow_init_req()
into the actual initialization and the mptcp-specific checks.
The initialization is moved before any possibly failing check.
