2025-11-11drm/i915/de: Have intel_de_wait() hand out the final register valueVille Syrjälä
We currently have a bunch of places that want the final register value after register polling. Currently those places are mostly using intel_de_wait_custom(). That is not a function that we want to keep around as it pretty much prevents conversion to poll_timeout_us(). Have intel_de_wait() also return the final register value so that some of the current users can be converted over to the simpler interface.

2025-11-11mmc: omap: add WQ_PERCPU to alloc_workqueue usersMarco Crivellari
Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default.

DISCONNECTED When smbd_disconnect_rdma_connection() turns SMBDIRECT_SOCKET_CREATED into SMBDIRECT_SOCKET_ERROR, we'll have the situation that smbd_disconnect_rdma_work() will set SMBDIRECT_SOCKET_DISCONNECTING and call rdma_disconnect(), which likely fails as we never reached the RDMA_CM_EVENT_ESTABLISHED. it means that wait_event(sc->status_wait, sc->status == SMBDIRECT_SOCKET_DISCONNECTED) in smbd_destroy() will hang forever in SMBDIRECT_SOCKET_DISCONNECTING never reaching SMBDIRECT_SOCKET_DISCONNECTED.

2025-11-11ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_baddHaein Lee
In snd_usb_create_streams(), for UAC version 3 devices, the Interface Association Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If this call fails, a fallback routine attempts to obtain the IAD from the next interface and sets a BADD profile. However, snd_usb_mixer_controls_badd() assumes that the IAD retrieved from usb_ifnum_to_if() is always valid, without performing a NULL check. This can lead to a NULL pointer dereference when usb_ifnum_to_if() fails to find the interface descriptor. This patch adds a NULL pointer check after calling usb_ifnum_to_if() in snd_usb_mixer_controls_badd() to prevent the dereference. This issue was discovered by syzkaller, which triggered the bug by sending a crafted USB device descriptor.

2025-11-11reset: mpfs: add non-auxiliary bus probingConor Dooley
While the auxiliary bus was a nice bandaid, and meant that re-writing the representation of the clock regions in devicetree was not required, it has run its course. The "mss_top_sysreg" region that contains the clock and reset regions, also contains pinctrl and an interrupt controller, so the time has come rewrite the devicetree and probe the reset controller from an mfd devicetree node, rather than implement those drivers using the auxiliary bus. Wanting to avoid propagating this naive/incorrect description of the hardware to the new pic64gx SoC is a major motivating factor here.

2025-11-11memblock: fix memblock_estimated_nr_free_pages() for soft-reserved memoryAkinobu Mita
memblock_estimated_nr_free_pages() returns the difference between the total size of the "memory" memblock type and the "reserved" memblock type. The "soft-reserved" memory regions are added to the "reserved" memblock type, but not to the "memory" memblock type. Therefore, memblock_estimated_nr_free_pages() may return a smaller value than expected, or if it underflows, an extremely large value. /proc/sys/kernel/threads-max is determined by the value of memblock_estimated_nr_free_pages(). This issue was discovered on machines with CXL memory because kernel.threads-max was either smaller than expected or extremely large for the installed DRAM size. This fixes the issue by replacing memblock_reserved_size() with memblock_reserved_kern_size() that tells how much memory was reserved from the actual RAM.

Move and rename the following MU user processing functions to wifi7/dp_mon.c with the ath12k_wifi7_ prefix: - ath12k_dp_mon_rx_handle_ofdma_info() - ath12k_dp_mon_rx_populate_mu_user_info() - ath12k_dp_mon_hal_rx_parse_user_info() Move the helper functions hal_rx_mon_hal_ru_size_to_ath12k_ru_size and hal_rx_ul_ofdma_ru_size_to_width to the Wi-Fi 7 module, and export the helpers required by the ath12k_wifi7 code. Isolate the parsing of MU-specific user information within the Wi-Fi 7 module to keep common code generic.

fc->fs_private commit 02f312754c87 ("ntfs3: fix use-after-free of sbi->options in cmp_fnames") introduced a use-after-free bug due to improper handling of sbi->options in error paths. This resulted in crashes when superblock cleanup is performed in ntfs_put_super. This patch ensures that the options structure and its subfields are properly freed, preventing the memory corruption and use-after-free errors.

2025-11-11fuse: fix readahead reclaim deadlockJoanne Koong
Commit e26ee4efbc79 ("fuse: allocate ff->release_args only if release is needed") skips allocating ff->release_args if the server does not implement open. However in doing so, fuse_prepare_release() now skips grabbing the reference on the inode, which makes it possible for an inode to be evicted from the dcache while there are inflight readahead requests. This causes a deadlock if the server triggers reclaim while servicing the readahead request and reclaim attempts to evict the inode of the file being read ahead. Since the folio is locked during readahead, when reclaim evicts the fuse inode and fuse_evict_inode() attempts to remove all folios associated with the inode from the page cache (truncate_inode_pages_range()), reclaim will block forever waiting for the lock since readahead cannot relinquish the lock because it is itself blocked in reclaim: >>> stack_trace(1504735) folio_wait_bit_common (mm/filemap.c:1308:4) folio_lock (./include/linux/pagemap.h:1052:3) truncate_inode_pages_range (mm/truncate.c:336:10) fuse_evict_inode (fs/fuse/inode.c:161:2) evict (fs/inode.c:704:3) dentry_unlink_inode (fs/dcache.c:412:3) __dentry_kill (fs/dcache.c:615:3) shrink_kill (fs/dcache.c:1060:12) shrink_dentry_list (fs/dcache.c:1087:3) prune_dcache_sb (fs/dcache.c:1168:2) super_cache_scan (fs/super.c:221:10) do_shrink_slab (mm/shrinker.c:435:9) shrink_slab (mm/shrinker.c:626:10) shrink_node (mm/vmscan.c:5951:2) shrink_zones (mm/vmscan.c:6195:3) do_try_to_free_pages (mm/vmscan.c:6257:3) do_swap_page (mm/memory.c:4136:11) handle_pte_fault (mm/memory.c:5562:10) handle_mm_fault (mm/memory.c:5870:9) do_user_addr_fault (arch/x86/mm/fault.c:1338:10) handle_page_fault (arch/x86/mm/fault.c:1481:3) exc_page_fault (arch/x86/mm/fault.c:1539:2) asm_exc_page_fault+0x22/0x27 Fix this deadlock by allocating ff->release_args and grabbing the reference on the inode when preparing the file for release even if the server does not implement open.
