Send unload command to smu during modprobe -r amdgpu for smu 13/14.
1. This can fix the high voltage/temperatue issue after driver is unloaded.
2. Reloading driver could fail but with the debug port based mode1 reset
during driver is reloaded, it is good and safe.

Currently DCE doesn't support the overlay cursor, so the
dm_crtc_get_cursor_mode() function returns DM_CURSOR_NATIVE_MODE
unconditionally. The outcome is that it doesn't check for the
conditions that would necessitate the overlay cursor, meaning
that it doesn't reject cases where the native cursor mode isn't
supported on DCE.
Remove the early return from dm_crtc_get_cursor_mode() for
DCE and instead let it perform the necessary checks and
return DM_CURSOR_OVERLAY_MODE. Add a later check that rejects
when DM_CURSOR_OVERLAY_MODE would be used with DCE.
Fixes: 1b04dcca4fb1 ("drm/amd/display: Introduce overlay cursor mode")

The driver uses strncmp() to compare sysfs attribute strings,
which does not handle trailing newlines and lacks NULL safety.
sysfs_streq() is the recommended function for sysfs string equality
checks in the kernel, providing safer and more correct behavior.
replace strncmp() with sysfs_streq() in drivers/gpu/drm/amd/pm/amdgpu_pm.c

The address watch clear code receives watch_id as an unsigned value
(u32), but some helper functions were using a signed int and checked
bits by shifting with watch_id.
If a very large watch_id is passed from userspace, it can be converted
to a negative value. This can cause invalid shifts and may access
memory outside the watch_points array.
drm/amdkfd: Fix watch_id bounds checking in debug address watch v2
Fix this by checking that watch_id is within MAX_WATCH_ADDRESSES before
using it. Also use BIT(watch_id) to test and clear bits safely.
This keeps the behavior unchanged for valid watch IDs and avoids
undefined behavior for invalid ones.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_debug.c:448
kfd_dbg_trap_clear_dev_address_watch() error: buffer overflow
'pdd->watch_points' 4 <= u32max user_rl='0-3,2147483648-u32max' uncapped
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_debug.c
433 int kfd_dbg_trap_clear_dev_address_watch(struct kfd_process_device *pdd,
434 uint32_t watch_id)
435 {
436 int r;
437
438 if (!kfd_dbg_owns_dev_watch_id(pdd, watch_id))
kfd_dbg_owns_dev_watch_id() doesn't check for negative values so if
watch_id is larger than INT_MAX it leads to a buffer overflow.
(Negative shifts are undefined).
439 return -EINVAL;
440
441 if (!pdd->dev->kfd->shared_resources.enable_mes) {
442 r = debug_lock_and_unmap(pdd->dev->dqm);
443 if (r)
444 return r;
445 }
446
447 amdgpu_gfx_off_ctrl(pdd->dev->adev, false);
--> 448 pdd->watch_points[watch_id] = pdd->dev->kfd2kgd->clear_address_watch(
449 pdd->dev->adev,
450 watch_id);
v2: (as per, Jonathan Kim)
- Add early watch_id >= MAX_WATCH_ADDRESSES validation in the set path to
match the clear path.
- Drop the redundant bounds check in kfd_dbg_owns_dev_watch_id().

amdgpu_ib_schedule() returns early after calling amdgpu_ring_undo().
This skips the common free_fence cleanup path. Other error paths were
already changed to use goto free_fence, but this one was missed.
Change the early return to goto free_fence so all error paths clean up
the same way.

amdgpu_dm_hpd_init() may see connectors without a valid dc_link.
The code already checks dc_link for the polling decision, but later
unconditionally dereferences it when setting up HPD interrupts.
Assign dc_link early and skip connectors where it is NULL.
Fixes the below:

The crash happens when we unconditionally call into the timing generator
manual trigger hook:
pipe_ctx->stream_res.tg->funcs->program_manual_trigger(...)
On some configurations the timing generator (tg), its funcs table, or the
program_manual_trigger callback can be NULL. Guard all of these before
calling the hook. If the first pipe matching the stream cannot trigger,
keep scanning to find another matching pipe with a valid hook.

Pull ext4 updates from Ted Ts'o:
"New features and improvements for the ext4 file system
- Avoid unnecessary cache invalidation in the extent status cache
(es_cache) when adding extents to be cached in the es_cache and we
are not changing the extent tree
- Add a sysfs parameter, err_report_sec, to control how frequently to
log a warning message that file system inconsistency has been
detected (Previously we logged the warning message every 24 hours)
- Avoid unnecessary forced ordered writes when appending to a file
when delayed allocation is enabled
- Defer splitting unwritten extents to I/O completion to improve
write performance of concurrent direct I/O writes to multiple files
- Refactor and add kunit tests to the extent splitting and conversion
code paths
Various Bug Fixes:
- Fix a panic when the debugging DOUBLE_CHECK macro is defined
- Avoid using fast commit for rare and complex file system operations
to make fast commit easier to reason about. This can also avoid
some corner cases that could result in file system inconsistency if
there is a crash between the fast commit before a subsequent full
commit
- Fix memory leaks in error paths
- Fix a false positive reports caused when running stress tests using
mixed huge-page workloads caused by a race between page migration
and bitmap updates
- Fix a potential recursion into file system reclaim when evicting an
inode when fast commit is enabled
- Fix a warning caused by a potential double decrement to the dirty
clusters counter when executing FS_IOC_SHUTDOWN when running a
stress test
- Enable mballoc optimized scanning regardless whether the inode is
using indirect blocks or extent trees to map blocks"

pci 0006:05:00.0: bridge window [??? 0x00001000-0x00001fff flags 0x20080000]: failed to assign
Those commits replace find_bus_resource_of_type() with
pbus_select_window_for_type(), and the latter lacks resource type
validation.
Add the resource type validation back to pbus_select_window_for_type() to
match the original behavior.

Pull nfsd updates from Chuck Lever:
"Neil Brown and Jeff Layton contributed a dynamic thread pool sizing
mechanism for NFSD. The sunrpc layer now tracks minimum and maximum
thread counts per pool, and NFSD adjusts running thread counts based
on workload: idle threads exit after a timeout when the pool exceeds
its minimum, and new threads spawn automatically when all threads are
busy. Administrators control this behavior via the nfsdctl netlink
interface.
Rick Macklem, FreeBSD NFS maintainer, generously contributed server-
side support for the POSIX ACL extension to NFSv4, as specified in
draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to
get and set POSIX access and default ACLs using native NFSv4
operations, eliminating the need for sideband protocols. The feature
is gated by a Kconfig option since the IETF draft has not yet been
ratified.
Chuck Lever delivered numerous improvements to the xdrgen tool. Error
reporting now covers parsing, AST transformation, and invalid
declarations. Generated enum decoders validate incoming values against
valid enumerator lists. New features include pass-through line support
for embedding C directives in XDR specifications, 16-bit integer
types, and program number definitions. Several code generation issues
were also addressed.
When an administrator revokes NFSv4 state for a filesystem via the
unlock_fs interface, ongoing async COPY operations referencing that
filesystem are now cancelled, with CB_OFFLOAD callbacks notifying
affected clients.
The remaining patches in this pull request are clean-ups and minor
optimizations. Sincere thanks to all contributors, reviewers, testers,
and bug reporters who participated in the v7.0 NFSD development cycle"

In ovpn_net_xmit, after GSO segmentation and segment processing, the
first segment on the list is used to increment VPN TX statistics, which
fails to account for any subsequent segments in the chain.
Fix this by accumulating the length of every segment that successfully
passes skb_share_check into a tx_bytes variable. This ensures the peer
statistics accurately reflect the total data volume sent, regardless of
whether the original packet was segmented.

When building the skb_list in ovpn_net_xmit, skb_share_check will free
the original skb if it is shared. The current implementation continues
to use the stale skb pointer for subsequent operations:
- peer lookup,
- skb_dst_drop (even though all segments produced by skb_gso_segment
will have a dst attached),
- ovpn_peer_stats_increment_tx.
Fix this by moving the peer lookup and skb_dst_drop before segmentation
so that the original skb is still valid when used. Return early if all
segments fail skb_share_check and the list ends up empty.
Also switch ovpn_peer_stats_increment_tx to use skb_list.next; the next
patch fixes the stats logic.

During initialization, we override socket callbacks and set sk_user_data
to an ovpn_socket instance. Currently, these two operations are
decoupled: callbacks are overridden before sk_user_data is set. While
existing callbacks perform safety checks for NULL or non-ovpn
sk_user_data, this condition causes a "half-formed" state where valid
packets arriving during attachment trigger error logs (e.g., "invoked on
non ovpn socket").
Set sk_user_data before overriding the callbacks so that it can be
accessed safely from them. Since we already check that the socket has no
sk_user_data before setting it, this remains safe even if an interrupt
accesses the socket after sk_user_data is set but before the callbacks
are overridden.
This also requires initializing all protocol-specific fields (such as
tcp_tx_work and peer links) before calling ovpn_socket_attach, ensuring
the ovpn_socket is fully formed before it becomes visible to any
callback.

On partitioned systems, multiple TPMI instances may exist per package,
but RAPL registers are only valid on one instance since RAPL has
package-scope control. Other instances return invalid versions during
domain parsing, which is expected behavior on such systems.
Currently this generates a firmware bug warning:
intel_rapl_tpmi: [Firmware Bug]: Invalid version
Remove the FW_BUG tag, downgrade to pr_debug(), and update the message
to clarify that invalid versions are expected on partitioned systems
where only one instance can be valid.

This patch introduces a count parameter to exfat_get_cluster, which
serves as an input parameter for the caller to specify the desired
number of clusters, and as an output parameter to store the length
of consecutive clusters.
This patch can improve read performance by reducing the number of
get_block calls in sequential read scenarios. speacially in small
cluster size.
According to my test data, the performance improvement is
approximately 10% when read FAT_CHAIN file with 512 bytes of
cluster size.
