regulator: bq257xx: Make OTG enable GPIO really optional
The bindings describe the OTG enable GPIO as optional, but the driver
gets upset if it's not provided in the device tree.

Make the driver accept the absence of the GPIO, and just use register
writes to handle OTG mode in that case, skipping the error message for
-ENOENT.

rsi_get_realm_config() passes its argument to virt_to_phys(), but

ASoC: amd: yc: Add MSI Vector A16 HX A8WHG to quirk table
Add the MSI Vector A16 HX A8WHG (board MS-15MM) to the DMI quirk table
to enable DMIC support. This laptop uses an AMD Ryzen 9 7945HX (Dragon
Range) with the ACP6x audio coprocessor (rev 0x62) and a Realtek ALC274
codec. The built-in digital microphone is connected via the ACP PDM
interface and requires this DMI entry to be activated.

Tested on MSI Vector A16 HX A8WHG with kernel 6.8.0-107 (Ubuntu 24.04).
DMIC capture device appears as 'acp6x' and records audio correctly.

ASoC: uda1380: Modernize the driver
This codec driver depended on the legacy GPIO API, and nothing
in the kernel is defining the platform data, so get rid of this.

Two in-kernel device trees are defining this codec using
undocumented device tree properties, so support these for now.
The same properties can be defined using software nodes if board
files are desired. The device tree use the "-gpio" rather than
"-gpios" suffix but the GPIO DT parser will deal with that.

Since there may be out of tree users, migrate to GPIO descriptors,
drop the platform data that is unused, and assign the dac_clk the
value that was used in all platforms found in a historical dig,
and support setting the clock to the PLL using the undocumented
device tree property.

Add some menuconfig so the codec can be selected and tested.

62443dc211 netfilter: require Ethernet MAC header before using eth_hdr()
`ip6t_eui64`, `xt_mac`, the `bitmap:ip,mac`, `hash:ip,mac`, and
`hash:mac` ipset types, and `nf_log_syslog` access `eth_hdr(skb)`
after either assuming that the skb is associated with an Ethernet
device or checking only that the `ETH_HLEN` bytes at
`skb_mac_header(skb)` lie between `skb->head` and `skb->data`.

Make these paths first verify that the skb is associated with an
Ethernet device, that the MAC header was set, and that it spans at
least a full Ethernet header before accessing `eth_hdr(skb)`.

f30e5a7291 netfilter: x_tables: Avoid a couple -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

Use the TRAILING_OVERLAP() helper to fix the following warnings:

1 net/netfilter/x_tables.c:816:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
1 net/netfilter/x_tables.c:811:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

This helper creates a union between a flexible-array member (FAM)
and a set of members that would otherwise follow it. This overlays
the trailing members onto the FAM while preserving the original
memory layout.

84dee05d9d netfilter: conntrack: remove UDP-Lite conntrack support
UDP-Lite (RFC 3828) socket support was recently retired from the core
networking stack. As a follow-up of that, drop the connection tracker
and NAT support for UDP-Lite in Netfilter.

This patch removes CONFIG_NF_CT_PROTO_UDPLITE and scrubs UDP-Lite
awareness from the conntrack core, NAT core, nft_ct, and ctnetlink.
Please note that stateless packet inspection, matching, ipsets or
logging support for IPPROTO_UDPLITE is preserved.

As conntrack no longer extracts UDP-Lite ports or tracks its L4 state,
when performing NAT the UDP-Lite checksum cannot be updated anymore.
That is an expected and acceptable consequence of removing UDP-Lite
conntrack module.

3f100dd61a xen/grant-table: guard gnttab_suspend/resume with CONFIG_HIBERNATE_CALLBACKS
In current linux.git, gnttab_suspend() and gnttab_resume() are defined
and declared unconditionally. However, their only in-tree callers reside
in drivers/xen/manage.c, which are guarded by CONFIG_HIBERNATE_CALLBACKS.

Match the helper scope to their callers by wrapping the definitions in
CONFIG_HIBERNATE_CALLBACKS and providing no-op stubs in the header. This
fixes the config-scope mismatch and reduces the code footprint when
hibernation callbacks are disabled.

bdd5de3d9e hvc/xen: Check console connection flag
When the console out buffer is filled, __write_console() will return 0
as it cannot send any data.  domU_write_console() will then spin in
`while (len)` as len doesn't decrement until xenconsoled attaches.  This
would block a domU and nullify the parallelism of Hyperlaunch until dom0
userspace starts xenconsoled, which empties the buffer.

Xen 4.21 added a connection field to the xen console page.  This is set
to XENCONSOLE_DISCONNECTED (1) when a domain is built, and xenconsoled
will set it to XENCONSOLE_CONNECTED (0) when it connects.

Update the hvc_xen driver to check the field.  When the field is
disconnected, drop the write with -ENOTCONN.  We only drop the write
when the field is XENCONSOLE_DISCONNECTED (1) to try for maximum
compatibility.  The Xen toolstack has historically zero initialized the
console, so it should see XENCONSOLE_CONNECTED (0) by default.  If an
implemenation used uninitialized memory, only checking for
XENCONSOLE_DISCONNECTED could have the lowest chance of not connecting.

This lets the hyperlaunched domU boot without stalling.  Once dom0
starts xenconsoled, xl console can be used to access the domU's hvc0.

Paritally sync console.h from xen.git to bring in the new field.

fdfdd01e80 xen/swiotlb: fix stale reference to swiotlb_unmap_page()
Commit af85de5a9f ("xen: swiotlb: Switch to physical
address mapping callbacks") renamed xen_swiotlb_unmap_page()
to xen_swiotlb_unmap_phys().  The comment in
xen_swiotlb_unmap_sg() had already been missing the xen_
prefix (reading swiotlb_unmap_page()), and the rename only
changed _page to _phys without correcting this, leaving it
as swiotlb_unmap_phys().  Fix the reference to use the
correct function name xen_swiotlb_unmap_phys().

7f8862d287 xen/manage: unwind partial shutdown watcher setup on error
setup_shutdown_watcher() registers shutdown_watch first, then the sysrq
watch, and finally publishes the supported feature-* nodes in xenstore.
If sysrq watch registration fails, or xenbus_printf() fails after one or
more feature nodes were created, the function returns immediately without
undoing the earlier setup.

This leaves the system in a partially initialized state, with registered
watches and/or stale xenstore entries despite the function reporting
failure.

Unwind the partial setup before returning an error by unregistering any
watches that were already registered and removing feature nodes that were
already published.

a5242d37c8 erofs: error out obviously illegal extents in advance
Detect some corrupted extent cases during metadata parsing rather
than letting them result in harmless decompression failures later:

 - For full-reference compressed extents, the compressed size must
   not exceed the decompressed size, which is a strict on-disk
   layout constraint;

 - For plain (shifted/interlaced) extents, the decoded size must
   not exceed the encoded size, even accounting for partial decoding.

Both ways work but it should be better to report illegal extents as
metadata layout violations rather than deferring as decompression
failure.

- Replace the EROFS_MAP_FULL_MAPPED flag with the opposite
  EROFS_MAP_PARTIAL_MAPPED flag so that extents are implicitly

- Make fragment extents independent of EROFS_MAP_MAPPED since

fdt_find_hyper_node() reads the raw compatible property and then derives
hyper_node.version from a prefix match before later printing it with %s.
Flat DT properties are external boot input, and this path does not prove

Keep the existing flat-DT lookup path, but verify that the first

71ba9a5cb1 sched_ext: Documentation: improve accuracy of task lifecycle pseudo-code
* Add ops.quiescent() and ops.runnable() to the sched_change path.
  When a queued task has one of its scheduling properties changed
  (e.g. nice, affinity), it goes through dequeue() -> quiescent() ->
  (property change callback, e.g. ops.set_weight()) -> runnable() ->
  enqueue().

* Change && to || in ops.enqueue() condition. We want to enqueue tasks
  that have a non-zero slice and are not in any DSQ.

* Call ops.dispatch() and ops.dequeue() only for tasks that have had
  ops.enqueue() called. This is to account for tasks direct-dispatched
  from ops.select_cpu().

* Add a note explaining that the pseudo-code provides a simplified view
  of the task lifecycle and list some examples of cases that the
  pseudo-code does not account for.

6522fe5c1b um: Disable GCOV_PROFILE_ALL on 32-bit UML with Clang 20/21
Clang 20 and 21 miscompute __builtin_object_size() when -fprofile-arcs
is active on 32-bit UML targets, which passes incorrect object size
calculations for local variables through always_inline copy_to_user()
and check_copy_size(), causing spurious compile-time errors:

  include/linux/ucopysize.h:52:4: error: call to '__bad_copy_from' declared with 'error' attribute: copy source size is too small

The regression was introduced in LLVM commit 02b8ee281947 ("[llvm]
Improve llvm.objectsize computation by computing GEP, alloca and malloc
parameters bound"), which shipped in Clang 20. It was fixed in LLVM
by commit 45b697e610fd ("[MemoryBuiltins] Consider index type size
when aggregating gep offsets"), which was backported to the LLVM 22.x
release branch.

The bug requires 32-bit UML + GCOV_PROFILE_ALL (which uses -fprofile-arcs),
though the exact trigger depends on optimizer decisions influenced by other
enabled configs.

Prevent the bad combination by disabling UML's ARCH_HAS_GCOV_PROFILE_ALL
on 32-bit when using Clang 20.x or 21.x.

We address the lock up issue first. The queue timeouts are due to

ppp_destroy_{channel,interface} are always called after
refcount_dec_and_test().

To reduce boilerplate code, consolidate the decrements by moving them
into the two functions. To reflect this change in semantics, rename the
functions to ppp_release_*.

84c5a3f000 net: phy: realtek: Add property to enable SSC
Add support for spread spectrum clocking (SSC) on RTL8211F(D)(I)-CG,
RTL8211FS(I)(-VS)-CG, RTL8211FG(I)(-VS)-CG PHYs. The implementation
follows EMI improvement application note Rev. 1.2 for these PHYs.

The current implementation enables SSC for both RXC and SYSCLK clock
signals. Introduce DT properties 'realtek,clkout-ssc-enable',
'realtek,rxc-ssc-enable' and 'realtek,sysclk-ssc-enable' which control
CLKOUT, RXC and SYSCLK SSC spread spectrum clocking enablement on these
signals.
