2025-08-29pppoe: drop sock reference counting on fast pathQingfang Deng
Now that PPPoE sockets are freed via RCU (SOCK_RCU_FREE), it is no longer necessary to take a reference count when looking up sockets on the receive path. Readers are protected by RCU, so the socket memory remains valid until after a grace period. Convert fast-path lookups to avoid refcounting: - Replace get_item() and sk_receive_skb() in pppoe_rcv() with __get_item() and __sk_receive_skb(). - Rework get_item_by_addr() into __get_item_by_addr() (no refcount and move RCU lock into pppoe_ioctl) - Remove unnecessary sock_put() calls. This avoids cacheline bouncing from atomic reference counting and improves performance on the receive fast path.

2025-08-29pppoe: remove rwlock usageQingfang Deng
Like ppp_generic.c, convert the PPPoE socket hash table to use RCU for lookups and a spinlock for updates. This removes rwlock usage and allows lockless readers on the fast path. - Mark hash table and list pointers as __rcu. - Use spin_lock() to protect writers. - Readers use rcu_dereference() under rcu_read_lock(). All known callers of get_item() already hold the RCU read lock, so no additional locking is needed. - get_item() now uses refcount_inc_not_zero() instead of sock_hold() to safely take a reference. This prevents crashes if a socket is already in the process of being freed (sk_refcnt == 0). - Set SOCK_RCU_FREE to defer socket freeing until after an RCU grace period. - Move skb_queue_purge() into sk_destruct callback to ensure purge happens after an RCU grace period.

2025-08-29mips: Replace __ASSEMBLY__ with __ASSEMBLER__ in the mips headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembler code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. Defining such a macro was necessary in the early days of the kernel, since GCC only started providing __ASSEMBLER__ since version 3.0 in 2000 (see https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=f8f769ea4e69 ). However, having two macros can be very confusing nowadays for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with just one comment tweaked manually in arch/mips/include/asm/cpu.h (that was missing some underscores).

2025-08-29Bluetooth: vhci: Prevent use-after-free by removing debugfs files earlyIvan Pravdin
Move the creation of debugfs files into a dedicated function, and ensure they are explicitly removed during vhci_release(), before associated data structures are freed. Previously, debugfs files such as "force_suspend", "force_wakeup", and others were created under hdev->debugfs but not removed in vhci_release(). Since vhci_release() frees the backing vhci_data structure, any access to these files after release would result in use-after-free errors. Although hdev->debugfs is later freed in hci_release_dev(), user can access files after vhci_data is freed but before hdev->debugfs is released.

2025-08-29nouveau: fix disabling the nonstall irq due to storm codeDave Airlie
Nouveau has code that when it gets an IRQ with no allowed handler it disables it to avoid storms. However with nonstall interrupts, we often disable them from the drm driver, but still request their emission via the push submission. Just don't disable nonstall irqs ever in normal operation, the event handling code will filter them out, and the driver will just enable/disable them at load time. This fixes timeouts we've been seeing on/off for a long time, but they became a lot more noticeable on Blackwell. This doesn't fix all of them, there is a subsequent fence emission fix to fix the last few.

Starting with commit f99508074e78 ("PM: domains: Detach on device_unbind_cleanup()"), there is no longer a need to call dev_pm_domain_detach() in the bus remove function. The device_unbind_cleanup() function now handles this to avoid invoking devres cleanup handlers while the PM domain is powered off, which could otherwise lead to failures as described in the above-mentioned commit.

2025-08-29drm/amd/display: Skip Check Runtime Link Setting for Specific Branch DeviceFangzhi Zuo
[why] Read link setting inside mode validation is not always the final downlink setting. It is found true in Synaptics branch device. At bootup, the preferred mode being set right after 1080p is set. It occurred before graphic load. That modeset switch in a short period of time makes the branch device switch back and forth from lower and higher link rate, observed at Synaptics branch device. DP2 RTK hub on the other hand, sticks to highest available downlink rate after bootup. Existing check of runtime downlink setting in mode validation shows asynchronous at branch device link switch, i.e., downlink switch to higher link rate not yet complete when the mode validation tries to probe the downlink setting. That makes mode validation checking downlink setting making wrong decision by pruning modes that should pass the validation after the downlink setting switch is complete.

2025-08-29drm/amd: Re-enable common modes for eDP and LVDSMario Limonciello
[Why] Although compositors will add their own modes, Xorg won't use it's own modes and will only stick to modes advertised by the driver.

2025-08-29drm/amdgpu: Check vcn state before profile switchLijo Lazar
The patch uses power state of VCN instances for requesting video profile. In idle worker of a vcn instance, when there is no outstanding submisssion or fence, the instance is put to power gated state. When all instances are powered off that means video profile is no longer required. A request is made to turn off video profile. A job submission starts with begin_use of ring, and at that time vcn instance state is changed to power on. Subsequently a check is made for active video profile, and if not active, a request is made.

2025-08-29hwmon: mlxreg-fan: Prevent fans from getting stuck at 0 RPMVadim Pasternak
The fans controlled by the driver can get stuck at 0 RPM if they are configured below a 20% duty cycle. The driver tries to avoid this by enforcing a minimum duty cycle of 20%, but this is done after the fans are registered with the thermal subsystem. This is too late as the thermal subsystem can set their current state before the driver is able to enforce the minimum duty cycle. Fix by setting the minimum duty cycle before registering the fans with the thermal subsystem.
