The "Other Logic Block" found in the EyeQ6Lplus from Mobileye provides
various functions for the controllers present in the SoC.
The OLB produces 22 clocks derived from its input, which is connected
to the main oscillator of the SoC.
It provides reset signals via two reset domains.
It also controls 32 pins to be either a GPIO or an alternate function.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
struct hci_std_codecs and struct hci_std_codecs_v2 are flexible
structures, this is structures that contain a flexible-array member
(__u8 codec[]; and struct hci_std_codec_v2 codec[];, correspondingly.)
Since struct hci_rp_read_local_supported_codecs and struct
hci_rp_read_local_supported_codecs_v2 are defined by hardware, we
create the new struct hci_std_codecs_hdr and struct hci_std_codecs_v2_hdr
types, and use them to replace the object types causing trouble in
struct hci_rp_read_local_supported_codecs and struct
hci_rp_read_local_supported_codecs_v2, namely struct hci_std_codecs
std_codecs; and struct hci_std_codecs_v2_hdr std_codecs;.
Also, once -fms-extensions is enabled, we can use transparent struct
members in both struct hci_std_codecs and struct hci_std_codecs_v2_hdr.
Notice that the newly created types does not contain the flex-array
member `codec`, which is the object causing the -Wfamnae warnings.
After these changes, the size of struct hci_rp_read_local_supported_codecs
and struct hci_rp_read_local_supported_codecs_v2, along with their
member's offsets remain the same, hence the memory layouts don't
change:
Before changes:
struct hci_rp_read_local_supported_codecs {
__u8 status; /* 0 1 */
struct hci_std_codecs std_codecs; /* 1 1 */
struct hci_vnd_codecs vnd_codecs; /* 2 1 */
/* size: 3, cachelines: 1, members: 3 */
/* last cacheline: 3 bytes */
} __attribute__((__packed__));
struct hci_rp_read_local_supported_codecs_v2 {
__u8 status; /* 0 1 */
struct hci_std_codecs_v2 std_codecs; /* 1 1 */
struct hci_vnd_codecs_v2 vendor_codecs; /* 2 1 */
/* size: 3, cachelines: 1, members: 3 */
/* last cacheline: 3 bytes */
} __attribute__((__packed__));
After changes:
struct hci_rp_read_local_supported_codecs {
__u8 status; /* 0 1 */
struct hci_std_codecs_hdr std_codecs; /* 1 1 */
struct hci_vnd_codecs vnd_codecs; /* 2 1 */
/* size: 3, cachelines: 1, members: 3 */
/* last cacheline: 3 bytes */
} __attribute__((__packed__));
struct hci_rp_read_local_supported_codecs_v2 {
__u8 status; /* 0 1 */
struct hci_std_codecs_v2_hdr std_codecs; /* 1 1 */
struct hci_vnd_codecs_v2 vendor_codecs; /* 2 1 */
/* size: 3, cachelines: 1, members: 3 */
/* last cacheline: 3 bytes */
} __attribute__((__packed__));

Separate the rx and tx enablement/disablement into different
functions so that it is easier to interact with them independently
later.
Although this patch changes receive and transmit paths, the actual
behavior of the teaming driver should remain unchanged, since there
is no option introduced yet to change rx or tx enablement
independently. Those options will be added in follow-up patches.

Add no functional changes, but rename enablement functions, variables
etc. that are used in teaming driver transmit decisions.
Since rx and tx enablement are still coupled, some of the variables
renamed in this patch are still used for the rx path, but that will
change in a follow-up patch.

Add support for GPIO type 0x02, which controls an IR flood LED used
for face authentication on some laptops (e.g. Dell Pro Max 16 Premium).
Without this patch, the kernel logs "GPIO type 0x02 unknown; the sensor
may not work" and IR sensors paired with a flood LED cannot function.
The flood LED is registered through the LED subsystem like the existing
privacy LED, including a lookup entry to allow future consumer drivers
to find and control it via led_get().
To support multiple LEDs per INT3472 device, convert the single led
struct member to an array with a counter.

KVM x86 VMXON and EFER.SVME extraction for 7.1
Move _only_ VMXON+VMXOFF and EFER.SVME toggling out of KVM (versus all of VMX
and SVM enabling) out of KVM and into the core kernel so that non-KVM TDX
enabling, e.g. for trusted I/O, can make SEAMCALLs without needing to ensure
KVM is fully loaded.
TIO isn't a hypervisor, and isn't trying to be a hypervisor. Specifically, TIO
should _never_ have it's own VMCSes (that are visible to the host; the
TDX-Module has it's own VMCSes to do SEAMCALL/SEAMRET), and so there is simply
no reason to move that functionality out of KVM.
With that out of the way, dealing with VMXON/VMXOFF and EFER.SVME is a fairly
simple refcounting game.

KVM/arm64 updates for 7.1
* New features:
- Add support for tracing in the standalone EL2 hypervisor code,
which should help both debugging and performance analysis.
This comes with a full infrastructure for 'remote' trace buffers
that can be exposed by non-kernel entities such as firmware.
- Add support for GICv5 Per Processor Interrupts (PPIs), as the
starting point for supporting the new GIC architecture in KVM.
- Finally add support for pKVM protected guests, with anonymous
memory being used as a backing store. About time!
* Improvements and bug fixes:
- Rework the dreaded user_mem_abort() function to make it more
maintainable, reducing the amount of state being exposed to
the various helpers and rendering a substantial amount of
state immutable.
- Expand the Stage-2 page table dumper to support NV shadow
page tables on a per-VM basis.
- Tidy up the pKVM PSCI proxy code to be slightly less hard
to follow.
- Fix both SPE and TRBE in non-VHE configurations so that they
do not generate spurious, out of context table walks that
ultimately lead to very bad HW lockups.
- A small set of patches fixing the Stage-2 MMU freeing in error
cases.
- Tighten-up accepted SMC immediate value to be only #0 for host
SMCCC calls.
- The usual cleanups and other selftest churn.

All current users of DRM pagemap set source_peer_migrates to true during
migration, and it is unclear whether any user would ever want to disable
this for performance reasons or for features such as compression. It is
also questionable whether this flag could be made to work with
high-speed fabric mapping APIs.
Drop the flag and make DRM pagemap unconditionally assume that
source_peer_migrates is true.

it operates on the root qdisc. If the root qdisc do not implement the
TCQ_F_DEQUEUE_DROPS flag the packets queue to free are never freed and
gets stranded on the child's local to_free list.
Fix this by making qdisc_dequeue_drop() aware of the root qdisc. It
fetches the root qdisc and check for the TCQ_F_DEQUEUE_DROPS flag. If
the flag is present, the packet is appended directly to the root's
to_free list. Otherwise, drop it directly as it was done before the
optimization was implemented.

Implement the .disable_autonomous_eee callback for the BCM54210E.
In AutogrEEEn mode the PHY manages EEE autonomously. Clearing the
AutogrEEEn enable bit in MII_BUF_CNTL_0 switches the PHY to Native
EEE mode.

Some PHYs (e.g. Broadcom BCM54xx, Realtek RTL8211F) implement
autonomous EEE where the PHY manages LPI signaling without forwarding
it to the MAC. This conflicts with MAC drivers that implement their own
LPI control.
Add a .disable_autonomous_eee callback to struct phy_driver and call it
from phy_support_eee(). When a MAC driver indicates it supports EEE via
phy_support_eee(), the PHY's autonomous EEE is automatically disabled so
the MAC can manage LPI entry/exit.

The nla_len field in struct nlattr is a __u16, which can only hold
values up to 65535. If a nested attribute grows beyond this limit,
nla_nest_end() silently truncates the length, producing a corrupted
netlink message with no indication of the problem.
Since nla_nest_end() is used everywhere and this issue rarely happens,
let's add a new helper to check the length.

Add struct tso_dma_map to tso.h for tracking DMA addresses of mapped
GSO payload data and tso_dma_map_completion_state.
The tso_dma_map combines DMA mapping storage with iterator state, allowing
drivers to walk pre-mapped DMA regions linearly. Includes fields for
the DMA IOVA path (iova_state, iova_offset, total_len) and a fallback
per-region path (linear_dma, frags[], frag_idx, offset).
The tso_dma_map_completion_state makes the IOVA completion state opaque
for drivers. Drivers are expected to allocate this and use the added
helpers to update the completion state.
Adds skb_frag_phys() to skbuff.h, returning the physical address
of a paged fragment's data, which is used by the tso_dma_map helpers
introduced in this commit described below.
The added TSO DMA map helpers are:
tso_dma_map_init(): DMA-maps the linear payload region and all frags
upfront. Prefers the DMA IOVA API for a single contiguous mapping with
one IOTLB sync; falls back to per-region dma_map_phys() otherwise.
Returns 0 on success, cleans up partial mappings on failure.
tso_dma_map_cleanup(): Handles both IOVA and fallback teardown paths.
tso_dma_map_count(): counts how many descriptors the next N bytes of
payload will need. Returns 1 if IOVA is used since the mapping is
contiguous.
tso_dma_map_next(): yields the next (dma_addr, chunk_len) pair.
On the IOVA path, each segment is a single contiguous chunk. On the
fallback path, indicates when a chunk starts a new DMA mapping so the
driver can set dma_unmap_len on that descriptor for completion-time
unmapping.
tso_dma_map_completion_save(): updates the completion state. Drivers
will call this at xmit time.
tso_dma_map_complete(): tears down the mapping at completion time and
returns true if the IOVA path was used. If it was not used, this is a
no-op and returns false.

Pull timer fixes from Thomas Gleixner:
"Two fixes for the time/timers subsystem:
- Invert the inverted fastpath decision in check_tick_dependency(),
which prevents NOHZ full to stop the tick. That's a regression
introduced in the 7.0 merge window.
- Prevent a unpriviledged DoS in the clockevents code, where user
space can starve the timer interrupt by arming a timerfd or posix
interval timer in a tight loop with an absolute expiry time in the
past. The fix turned out to be incomplete and was was amended
yesterday to make it work on some 20 years old AMD machines as
well. All issues with it have been confirmed to be resolved by
various reporters"

Florian Westphal says:
====================
netfilter: updates for net-next
1-3) IPVS updates from Julian Anastasov to enhance visibility into
IPVS internal state by exposing hash size, load factor etc and
allows userspace to tune the load factor used for resizing hash
tables.
4) reject empty/not nul terminated device names from xt_physdev.
This isn't a bug fix; existing code doesn't require a c-string.
But clean this up anyway because conceptually the interface name
definitely should be a c-string.
5) Switch nfnetlink to skb_mac_header helpers that didn't exist back
when this code was written. This gives us additional debug checks
but is not intended to change functionality.
6) Let the xt ttl/hoplimit match reject unknown operator modes.
This is a cleanup, the evaluation function simply returns false when
the mode is out of range. From Marino Dzalto.
7) xt_socket match should enable defrag after all other checks. This
bug is harmless, historically defrag could not be disabled either
except by rmmod.
8) remove UDP-Lite conntrack support, from Fernando Fernandez Mancera.
9) Avoid a couple -Wflex-array-member-not-at-end warnings in the old
xtables 32bit compat code, from Gustavo A. R. Silva.
10) nftables fwd expression should drop packets when their ttl/hl has
expired. This is a bug fix deferred, its not deemed important
enough for -rc8.
11) Add additional checks before assuming the mac header is an ethernet
header, from Zhengchuan Liang.
