bc0c7fd732 drm/i915: Nuke intel_plane_ggtt_offset()
We don't really need the extra intel_plane_ggtt_offset() wrapper
anymore. Get rid of it.

v2: Deal with reuse_vma() hacks

971eb92b04 drm/i915: Precompute plane SURF address
Currently we pre-compute the plane surface/base address
partially (only for cursor_needs_physical cases) in
intel_plane_pin_fb() and finish the calculation in the
plane->update_arm(). Let's just precompute the whole thing
instead.

One benefit is that we get rid of all the vma offset stuff
from the low level plane code. Another use I have in mind
is including the surface address in the plane tracepoints,
which should make it easier to analyze display faults.

v2: Deal with xe reuse_vma() hacks
v3: use intel_plane_ggtt_offset() still in reuse_vma()

b5e8acc14d tracing: Add down_write(trace_event_sem) when adding trace event
When a module is loaded, it adds trace events defined by the module. It
may also need to modify the modules trace printk formats to replace enum
names with their values.

If two modules are loaded at the same time, the adding of the event to the
ftrace_events list can corrupt the walking of the list in the code that is
modifying the printk format strings and crash the kernel.

The addition of the event should take the trace_event_sem for write while
it adds the new event.

Also add a lockdep_assert_held() on that semaphore in
__trace_add_event_dirs() as it iterates the list.

615c8ec486 drm/i915/dsi: Don't set/read the DSI C clock divider on GLK
GLK doesn't use the DSI C clock at all, no need to program
the divider for it. Bspec even says: "Do not program this field".

However looks like some firmware versions program this and
some do not. In order to avoid bogus fastset mismatches
we should also filter it out during readout.

v2: Clear all the DSI C clock bits during readout (Jani)
    Adjust platform checks for new style, and add
    has_dsic_clock() while at it.

Offloading encapsulation and decapsulation to hardware can

Currently, the ath12k driver supports only the native Wi-Fi
frame format. In this mode, the ieee80211_tx_status() function
works correctly to report transmission status to mac80211, as
it retrieves station information using sta_info_get_by_addrs().

However, this method is not applicable for Ethernet-converted
packets, since sta_info_get_by_addrs() cannot extract station
information from such formats.

Retrieve station information using ath12k_peer_find_by_id() to
support all frame formats, including native Wi-Fi, raw, and Ethernet.
Report transmission status using ieee80211_tx_status_ext(), and
include rate information as part of the datapath TX status report.

646faf36d7 cgroup: Add compatibility option for content of /proc/cgroups
/proc/cgroups lists only v1 controllers by default, however, this is
only enforced since the commit af000ce852 ("cgroup: Do not report
unavailable v1 controllers in /proc/cgroups") and there is software in
the wild that uses content of /proc/cgroups to decide on availability of
v2 (sic) controllers.

Add a boottime param that can bring back the previous behavior for
setups where the check in the software cannot be changed and it causes
e.g. unintended OOMs.

Also, this patch takes out cgrp_v1_visible from cgroup1_subsys_absent()
guard since it's only important to check which hierarchy (v1 vs v2) the
subsys is attached to. This has no effect on the printed message but
the code is cleaner since cgrp_v1_visible is really about mounted
hierarchies, not the content of /proc/cgroups.

192c8e9a13 wifi: ath12k: Fix the handling of TX packets in Ethernet mode
Currently, in the transmit (TX) direction, EAPOL, QoS NULL,
and multicast frames are sent in native Wi-Fi (802.11) format.
However, when the virtual interface is configured in Ethernet
mode, transmission fails for packets enqueued in native Wi-fi format.

To address this issue, the firmware should be instructed to
treat these packets as RAW type packets, ensuring proper
handling even when the interface operates in Ethernet mode.

Youssef Samir
5bd398e20f bus: mhi: host: Detect events pointing to unexpected TREs
When a remote device sends a completion event to the host, it contains a
pointer to the consumed TRE. The host uses this pointer to process all of
the TREs between it and the host's local copy of the ring's read pointer.
This works when processing completion for chained transactions, but can
lead to nasty results if the device sends an event for a single-element
transaction with a read pointer that is multiple elements ahead of the
host's read pointer.

For instance, if the host accesses an event ring while the device is
updating it, the pointer inside of the event might still point to an old
TRE. If the host uses the channel's xfer_cb() to directly free the buffer
pointed to by the TRE, the buffer will be double-freed.

This behavior was observed on an ep that used upstream EP stack without
'commit 6f18d174b7 ("bus: mhi: ep: Update read pointer only after buffer
is written")'. Where the device updated the events ring pointer before
updating the event contents, so it left a window where the host was able to
access the stale data the event pointed to, before the device had the
chance to update them. The usual pattern was that the host received an
event pointing to a TRE that is not immediately after the last processed
one, so it got treated as if it was a chained transaction, processing all
of the TREs in between the two read pointers.

This commit aims to harden the host by ensuring transactions where the
event points to a TRE that isn't local_rp + 1 are chained.

    ath12k_pci: probe of 0001:01:00.0 failed with error -110

The issue seems to be with the incorrect DMA address/size used for
transferring the firmware image over BHI. So fix it by converting the DMA
address and size of the BHI vector table to little endian format before
sending them to the device.

5b4c56ad4d net/mlx5: E-Switch, Fix peer miss rules to use peer eswitch
In the original design, it is assumed local and peer eswitches have the
same number of vfs. However, in new firmware, local and peer eswitches
can have different number of vfs configured by mlxconfig.  In such
configuration, it is incorrect to derive the number of vfs from the
local device's eswitch.

Fix this by updating the peer miss rules add and delete functions to use
the peer device's eswitch and vf count instead of the local device's
information, ensuring correct behavior regardless of vf configuration
differences.

4701ee5044 be2net: Use correct byte order and format string for TCP seq and ack_seq
The TCP header fields seq and ack_seq are 32-bit values in network
byte order as (__be32). these fields were earlier printed using
ntohs(), which converts only 16-bit values and produces incorrect
results for 32-bit fields. This patch is changeing the conversion
to ntohl(), ensuring correct interpretation of these sequence numbers.

Notably, the format specifier is updated from %d to %u to reflect the
unsigned nature of these fields.

improves the accuracy of debug log messages for TCP sequence and
