git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking deletions from Jakub Kicinski: "Delete some obsolete networking code Old code like amateur radio and NFC have long been a burden to core networking developers. syzbot loves to find bugs in BKL-era code, and noobs try to fix them. If we want to have a fighting chance of surviving the LLM-pocalypse this code needs to find a dedicated owner or get deleted. We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code. We were lucky enough to find someone who wants to help with NFC so we're giving that a chance. Let's try to put the rest of this code behind us" * tag 'net-deletions' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: drivers: net: 8390: wd80x3: Remove this driver drivers: net: 8390: ultra: Remove this driver drivers: net: 8390: AX88190: Remove this driver drivers: net: fujitsu: fmvj18x: Remove this driver drivers: net: smsc: smc91c92: Remove this driver drivers: net: smsc: smc9194: Remove this driver drivers: net: amd: nmclan: Remove this driver drivers: net: amd: lance: Remove this driver drivers: net: 3com: 3c589: Remove this driver drivers: net: 3com: 3c574: Remove this driver drivers: net: 3com: 3c515: Remove this driver drivers: net: 3com: 3c509: Remove this driver net: packetengines: remove obsolete yellowfin driver and vendor dir net: packetengines: remove obsolete hamachi driver net: remove unused ATM protocols and legacy ATM device drivers net: remove ax25 and amateur radio (hamradio) subsystem net: remove ISDN subsystem and Bluetooth CMTP caif: remove CAIF NETWORK LAYER
2026-04-23net: remove ax25 and amateur radio (hamradio) subsystemJakub Kicinski4-12/+0
Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation and all associated hamradio device drivers from the kernel tree. This set of protocols has long been a huge bug/syzbot magnet, and since nobody stepped up to help us deal with the influx of the AI-generated bug reports we need to move it out of tree to protect our sanity. The code is moved to an out-of-tree repo: https://github.com/linux-netdev/mod-orphan if it's cleaned up and reworked there we can accept it back. Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP, AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN) so that the conditional integration code in arp.c and tun.c continues to compile and work when the out-of-tree modules are loaded.

2026-04-23caif: remove CAIF NETWORK LAYERJakub Kicinski1-1/+0
Remove CAIF (Communication CPU to Application CPU Interface), the ST-Ericsson modem protocol. The subsystem has been orphaned since 2013. The last meaningful changes from the maintainers were in March 2013: a8c7687bf216 ("caif_virtio: Check that vringh_config is not null") b2273be8d2df ("caif_virtio: Use vringh_notify_enable correctly") 0d2e1a2926b1 ("caif_virtio: Introduce caif over virtio") Not-so-coincidentally, according to "the Internet" ST-Ericsson officially shut down its modem joint venture in Aug 2013. If anyone is using this code please yell! In the 13 years since, the code has accumulated 200 non-merge commits, of which 71 were cross-tree API changes, 21 carried Fixes: tags, and the remaining ~110 were cleanups, doc conversions, treewide refactors, and one partial removal (caif_hsi, ca75bcf0a83b). We are still getting fixes to this code, in the last 10 days there were 3 reports on security@ about CAIF that I have been CCed on. UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the SELinux classmap entry are intentionally kept for ABI stability. Acked-by: Michael S.

Mainly cleanups, also some locking simplification (David Hildenbrand) - "mm/vmscan: add tracepoint and reason for kswapd_failures reset" adds additional tracepoints to the page reclaim code (Jiayuan Chen) - "Replace wq users and add WQ_PERCPU to alloc_workqueue() users" is part of Marco's kernel-wide migration from the legacy workqueue APIs over to the preferred unbound workqueues (Marco Crivellari) - "Various mm kselftests improvements/fixes" provides various unrelated improvements/fixes for the mm kselftests (Kevin Brodsky) - "mm: accelerate gigantic folio allocation" greatly speeds up gigantic folio allocation, mainly by avoiding unnecessary work in pfn_range_valid_contig() (Kefeng Wang) - "selftests/damon: improve leak detection and wss estimation reliability" improves the reliability of two of the DAMON selftests (SeongJae Park) - "mm/damon: cleanup kdamond, damon_call(), damos filter and DAMON_MIN_REGION" does some cleanup work in the core DAMON code (SeongJae Park) - "Docs/mm/damon: update intro, modules, maintainer profile, and misc" performs maintenance work on the DAMON documentation (SeongJae Park) - "mm: add and use vma_assert_stabilised() helper" refactors and cleans up the core VMA code. The main aim here is to be able to use the mmap write lock's lockdep state to perform various assertions regarding the locking which the VMA code requires (Lorenzo Stoakes) - "mm, swap: swap table phase II: unify swapin use" removes some old swap code (swap cache bypassing and swap synchronization) which wasn't working very well. Various other cleanups and simplifications were made. The end result is a 20% speedup in one benchmark (Kairui Song) - "enable PT_RECLAIM on more 64-bit architectures" makes PT_RECLAIM available on 64-bit alpha, loongarch, mips, parisc, and um.

2026-01-27arch, mm: consolidate initialization of SPARSE memory modelMike Rapoport (Microsoft)1-2/+0
Every architecture calls sparse_init() during setup_arch() although the data structures created by sparse_init() are not used until the initialization of the core MM. Beside the code duplication, calling sparse_init() from architecture specific code causes ordering differences of vmemmap and HVO initialization on different architectures. Move the call to sparse_init() from architecture specific code to free_area_init() to ensure that vmemmap and HVO initialization order is always the same.

2026-01-23docs: ja_JP: Start translation of submitting-patchesAkiyoshi Kurita2-0/+39
Start a new Japanese translation of Documentation/process/submitting-patches.rst. Instead of moving the outdated 2011 translation (SubmittingPatches), we are starting a fresh translation of the current English document. This patch adds the initial file structure, the warning about the document being under construction, and the translation of the introduction section. The translation work will be done incrementally.

2026-01-07Docs/translations/ko_KR: remove memory-barriersSeongJae Park3-2971/+0
The memory-barriers.txt Korean translation is quite outdated. The last update on the translation was made on 2022-10-10, by commit ee5a86f451f7 ("docs/memory-barriers.txt/kokr: Fix confusing name of 'data dependency barrier'"). After the date, the original memory-barriers.txt got seven more changes so far. The most recent one was made on 2025-11-05. But none of those are applied to the translation. Maybe I can work again on keeping it updated. But, given the advancement of translation tools, I think it might not be worth keeping it at all. Remove the outdated translation. If it turns out to be worthy to keep the translation and someone willing to keep it updated steps up, this could be reverted. This change was inspired from the last kernel summit discussion [1].
