c93799de1b net: page_pool: support dumping pps of a specific ifindex via Netlink 
NIPA tries to make sure that HW tests don't modify system state.
It saves the state of page pools, too. Now that I write this commit
message I realize that this is impractical since page pool IDs and
state will get legitimately changed by the tests. But I already
spent a couple of hours implementing the filtering, so..

11f00074f7 cgroup: Fixes for v7.1-rc2 
- During v6.19, cgroup task unlink was moved from do_exit() to after the
   final task switch to satisfy a controller invariant. That left the kernel
   seeing tasks past exit_signals() longer than userspace expected, and
   several v7.0 follow-ups tried to bridge the gap by making rmdir wait for
   the kernel side. None held up. The latest is an A-A deadlock when rmdir
   is invoked by the reaper of zombies whose pidns teardown the rmdir itself
   is waiting on, which points at the synchronizing approach being
   fundamentally wrong:
 
   - Take a different approach: drop the wait, leave rmdir's user-visible
     side returning as soon as cgroup.procs is empty, and defer the css
     percpu_ref kill that drives ->css_offline() until the cgroup is fully
     depopulated.
 
   - Tagged for stable. Somewhat invasive but contained. The hope is that
     fixing forward sticks. If not, the fallback is to revert the entire
     chain and rework on the development branch.
 
   - Doesn't plug a pre-existing analogous race in
     cgroup_apply_control_disable() (controller disable via subtree_control).
     Not a regression. The development branch will do the more invasive
     restructuring needed for that.
 
 - Documentation update for cgroup-v1 charge-commit section that still
   referenced functions removed when the memcg hugetlb try-commit-cancel
   protocol was retired.

4fe18ddd17 ne2k: fold drivers/net/Space.c into ne.c 
drivers/net/Space.c is the last remnant of the linux-2.4.x driver model
that required each subsystem and device driver init function to be called
from init/main.c explicitly, before the introduction of initcall levels.

In linux-7.0, this was only used for a handful of ISA network drivers,
with the ne2000 driver being the last one.

Fold the code into ne.c directly, with minimal changes to preserve
the existing command line parsing.

93cda0c120 net: cs89x0: remove ISA bus probing 
The cs89x0 driver is really two in one, and they are mutually exclusive:

 - the ISA driver was used on 486-era PCs. It likely has no remaining
   users, like the other ethernet drivers that got removed in
   linux-7.1. The DMA support in here is the last device driver use of
   the deprecated isa_bus_to_virt() interface, all other users are either
   x86 specific or or got converted to the normal dma-mapping interface.
   The driver was maintained by Andrew Morton at the time, based on
   the linux-2.2 vendor driver from Cirrus Logic.

 - the platform_driver instance was used on some embedded Arm boards
   around the same time, such as the EP7211 Development Kit. This
   is the same chip, but uses modern devicetree based probing and no DMA.
   This was added by Alexander Shiyan.

Remove the ISA driver as a cleanup, including all of the outdated
documentation referring to its configuration.

781c8893a5 dpll: add pin operational state 
Add pin-operstate enum and operstate_on_dpll_get callback to report
the actual hardware status of a pin with respect to its parent DPLL
device. Unlike pin-state (which reflects administrative intent set
by the user), operstate reflects what the hardware is actually doing.

Defined operational states:
  - active: pin is qualified and actively used by the DPLL
  - standby: pin is qualified but not actively used by the DPLL
  - no-signal: pin does not have a valid signal
  - qual-failed: pin signal failed qualification

The operstate is reported inside the pin-parent-device nested
attribute alongside the existing state and phase-offset attributes.

b2680ba4a2 spi: Fixes for v7.1 
This is quite a big set of fixes, almost all from Johan Hovold who is on
 an ongoing quest to clean up issues with probe and removal handling in
 drivers.  There isn't anything too concerning here especially with the
 deregistration stuff which will very rarely get run in production
 systems since this is all platform devices in the SoC on embedded
 hardware, but it's all real issues which should be fixed.  There's more
 in flight here.
 
 We also have a few other minor fixes, one from Felix Gu along the same
 lines as Johan's work and a couple of documentation things.

Pull RISC-V updates from Paul Walmsley:
 "There is one significant change outside arch/riscv in this pull
  request: the addition of a set of KUnit tests for strlen(), strnlen(),
  and strrchr().

  Otherwise, the most notable changes are to add some RISC-V-specific
  string function implementations, to remove XIP kernel support, to add
  hardware error exception handling, and to optimize our runtime
  unaligned access speed testing.

  A few comments on the motivation for removing XIP support. It's been
  broken in the RISC-V kernel for months. The code is not easy to
  maintain. Furthermore, for XIP support to truly be useful for RISC-V,
  we think that compile-time feature switches would need to be added for
  many of the RISC-V ISA features and microarchitectural properties that
  are currently implemented with runtime patching. No one has stepped
  forward to take responsibility for that work, so many of us think it's
  best to remove it until clear use cases and champions emerge.

  Summary:

   - Add Kunit correctness testing and microbenchmarks for strlen(),
     strnlen(), and strrchr()

   - Add RISC-V-specific strnlen(), strchr(), strrchr() implementations

   - Add hardware error exception handling

   - Clean up and optimize our unaligned access probe code

   - Enable HAVE_IOREMAP_PROT to be able to use generic_access_phys()

   - Remove XIP kernel support

   - Warn when addresses outside the vmemmap range are passed to
     vmemmap_populate()

   - Update the ACPI FADT revision check to warn if it's not at least
     ACPI v6.6, which is when key RISC-V-specific tables were added to
     the specification

   - Increase COMMAND_LINE_SIZE to 2048 to match ARM64, x86, PowerPC,
     etc.

   - Make kaslr_offset() a static inline function, since there's no need
     for it to show up in the symbol table

   - Add KASLR offset and SATP to the VMCOREINFO ELF notes to improve
     kdump support

   - Add Makefile cleanup rule for vdso_cfi copied source files, and add
     a .gitignore for the build artifacts in that directory

   - Remove some redundant ifdefs that check Kconfig macros

   - Add missing SPDX license tag to the CFI selftest

   - Simplify UTS_MACHINE assignment in the RISC-V Makefile

   - Clarify some unclear comments and remove some superfluous comments

   - Fix various English typos across the RISC-V codebase"

64edfa6506 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.

 Nice thing is these are often fixed by the respective maintainers,
 not drive-bys.

drivers (drivers/usb/atm/) are retained in-tree to maintain PPP
over ATM (PPPoA) and PPPoE-over-BR2684 support for DSL connections.
The Solos ADSL2+ PCI driver is also retained.

Removed ATM protocol modules:
 - net/atm/clip.c - Classical IP over ATM (RFC 2225)
 - net/atm/lec.c - LAN Emulation Client (LANE)
 - net/atm/mpc.c, mpoa_caches.c, mpoa_proc.c - Multi-Protocol Over ATM

Removed PCI/SBUS ATM device drivers (drivers/atm/):
 - adummy, atmtcp - software/testing ATM devices
 - eni - Efficient Networks ENI155P (OC-3, ~1995)
 - fore200e - FORE Systems 200E PCI/SBUS (OC-3, ~1999)
 - he - ForeRunner HE (OC-3/OC-12, ~2000)
 - idt77105 - IDT 77105 25 Mbps ATM PHY
 - idt77252 - IDT 77252 NICStAR II (OC-3, ~2000)
 - iphase - Interphase ATM PCI (OC-3/DS3/E3)
 - lanai - Efficient Networks Speedstream 3010
 - nicstar - IDT 77201 NICStAR (155/25 Mbps, ~1999)
 - suni - PMC S/UNI SONET PHY library

Also clean up references in:
 - net/bridge/ - remove ATM LANE hook (br_fdb_test_addr_hook,
   br_fdb_test_addr)
 - net/core/dev.c - remove br_fdb_test_addr_hook export
 - defconfig files - remove ATM driver config options

The removed code is moved to an out-of-tree module package (mod-orphan).

dd8d4bc28a net: remove ax25 and amateur radio (hamradio) subsystem 
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.

4f10f1dfb2 net: remove ISDN subsystem and Bluetooth CMTP 
Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol
from the kernel tree.

ISDN is a pretty old technology and it's unclear whether anyone still
uses it. I went over the last few years of git history and all the
commits are either tree-wide conversions or syzbot/static analyzer
fixes.

When we discussed removal in the past IIRC there were some concerns
about ISDN still being used in parts of Germany. Unfortunately, the
code base is quite old, none of the current maintainers are familiar
with it and AI tools will have a field day finding bugs here.

Delete this code and preserve it in an out-of-tree repository
for any remaining users:
https://github.com/linux-netdev/mod-orphan

UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class
are preserved for ABI stability, but the rest of uAPI is removed.

6d5431555d caif: remove CAIF NETWORK LAYER 
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:
  a8c7687bf2 ("caif_virtio: Check that vringh_config is not null")
  b2273be8d2 ("caif_virtio: Use vringh_notify_enable correctly")
  0d2e1a2926 ("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, ca75bcf0a8).

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.

507bd4b66c soc: late changes for 7.1 
These are the contents that arrived during the easter vacation and didn't
 make it into the last 7.0 bugfixes or the first set of branches for the
 merge window. Aside from a reset controller bugfix and an update to the
 MAINTAINERS entry, this is all devicetree changes.
 
 The Marvell devicetree updates contain the usual minor updates and bugfixes,
 along with a two larger but trivial patches to drop unused dtsi files,
 the single broadcom fix addresses a build time warning introduced during
 the merge window.
 
 The freescale, amlogic, and apple changes missed the last fixes branch
 for 7.0.

2a4c0c11c0 s390 updates for 7.1 merge window 
- Add support for CONFIG_PAGE_TABLE_CHECK and enable it in
   debug_defconfig. s390 can only tell user from kernel PTEs via the mm,
   so mm_struct is now passed into pxx_user_accessible_page() callbacks
 
 - Expose the PCI function UID as an arch-specific slot attribute in
   sysfs so a function can be identified by its user-defined id while
   still in standby. Introduces a generic ARCH_PCI_SLOT_GROUPS hook in
   drivers/pci/slot.c
 
 - Refresh s390 PCI documentation to reflect current behavior and cover
   previously undocumented sysfs attributes
 
 - zcrypt device driver cleanup series: consistent field types, clearer
   variable naming, a kernel-doc warning fix, and a comment explaining
   the intentional synchronize_rcu() in pkey_handler_register()
 
 - Provide an s390 arch_raw_cpu_ptr() that avoids the detour via
   get_lowcore() using alternatives, shrinking defconfig by ~27 kB
 
 - Guard identity-base randomization with kaslr_enabled() so nokaslr
   keeps the identity mapping at 0 even with
   CONFIG_RANDOMIZE_IDENTITY_BASE=y
 
 - Build S390_MODULES_SANITY_TEST as a module only by requiring
   KUNIT && m, since built-in would not exercise module loading
 
 - Remove the permanently commented-out HMCDRV_DEV_CLASS create_class()
   code in the hmcdrv driver
 
 - Drop stale ident_map_size extern conflicting with asm/page.h

4ee64205ff We've finally gotten rid of the struct clk_ops::round_rate() code after months 
of effort from Brian Masney. Now the only option is to use determine_rate(),
 which is good because that takes a struct argument instead of just a couple
 unsigned longs, allowing us to easily modify the way we determine and set rates
 in the clk tree.
 
 Beyond that core framework change we've got the typical pile of new SoC clk
 driver additions, fixes for clk data and/or adding missing clks because the
 consumer driver using those clks wasn't ready, etc. The usual suspects are all
 here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
 making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
 driver side of this looks pretty normal.
 
 Core:
  - Remove the round_rate() clk op (yay!)
 
 New Drivers:
  - ESWIN eic700 SoC clk support
  - Econet EN751221 SoC clock/reset support
  - Global TCSR, RPMh, and display clock controller support for
    the Qualcomm Eliza platform
  - TCSR, the multiple global, and the RPMh clock controller
    support for the Qualcomm Nord platform
  - GPU clock controller support for Qualcomm SM8750
  - Video and GPU clock controller support for Qualcomm Glymur
  - Global clock controller support for Qualcomm IPQ5210
  - Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
    controllers on the SoC
  - ExynosAutov920: Add G3D (GPU) clock controller
  - Clock driver for the Rockchip RV1103B SoC
  - Initial support for the Renesas RZ/G3L (R9A08G046) SoC
  - Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "We've finally gotten rid of the struct clk_ops::round_rate() code
  after months of effort from Brian Masney. Now the only option is to
  use determine_rate(), which is good because that takes a struct
  argument instead of just a couple unsigned longs, allowing us to
  easily modify the way we determine and set rates in the clk tree.

  Beyond that core framework change we've got the typical pile of new
  SoC clk driver additions, fixes for clk data and/or adding missing
  clks because the consumer driver using those clks wasn't ready, etc.
  The usual suspects are all here: Qualcomm, Samsung, Mediatek, and
  Rockchip along with some newcomers making RISC-V SoCs like ESWIN's
  eic700 and Tenstorrent's Atlantis. The clk driver side of this looks
  pretty normal.

  Core:
   - Remove the round_rate() clk op (yay!)

  New Drivers:
   - ESWIN eic700 SoC clk support
   - Econet EN751221 SoC clock/reset support
   - Global TCSR, RPMh, and display clock controller support for the
     Qualcomm Eliza platform
   - TCSR, the multiple global, and the RPMh clock controller support
     for the Qualcomm Nord platform
   - GPU clock controller support for Qualcomm SM8750
   - Video and GPU clock controller support for Qualcomm Glymur
   - Global clock controller support for Qualcomm IPQ5210
   - Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
     controllers on the SoC
   - ExynosAutov920: Add G3D (GPU) clock controller
   - Clock driver for the Rockchip RV1103B SoC
   - Initial support for the Renesas RZ/G3L (R9A08G046) SoC
   - Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC"

292a2bcd17 Fixing livelocks in shrink_dcache_tree() 
If shrink_dcache_tree() finds a dentry in the middle of being killed
 by another thread, it has to wait until the victim finishes dying,
 gets detached from the tree and ceases to pin its parent.
 
 The way we used to deal with that amounted to busy-wait; unfortunately,
 it's not just inefficient but can lead to reliably reproducible hard
 livelocks.
 
 Solved by having shrink_dentry_tree() attach a completion to such dentry,
 with dentry_unlist() calling complete() on all objects attached to it.
 With a bit of care it can be done without growing struct dentry or adding
 overhead in normal case.

7ef83bf171 net: move promiscuity handling into netdev_rx_mode_work 
Move unicast promiscuity tracking into netdev_rx_mode_work so it runs
under netdev_ops_lock instead of under the addr_lock spinlock. This
is required because __dev_set_promiscuity calls dev_change_rx_flags
and __dev_notify_flags, both of which may need to sleep.

Change ASSERT_RTNL() to netdev_ops_assert_locked() in
__dev_set_promiscuity, netif_set_allmulti and __dev_change_flags
since these are now called from the work queue under the ops lock.

Link: https://lore.kernel.org/netdev/20260214033859.43857-1-jiayuan.chen@linux.dev/
Fixes: 78cd408356 ("net: add missing instance lock to dev_set_promiscuity")

3554b4345d net: introduce ndo_set_rx_mode_async and netdev_rx_mode_work 
Add ndo_set_rx_mode_async callback that drivers can implement instead
of the legacy ndo_set_rx_mode. The legacy callback runs under the
netif_addr_lock spinlock with BHs disabled, preventing drivers from
sleeping. The async variant runs from a work queue with rtnl_lock and
netdev_lock_ops held, in fully sleepable context.

When __dev_set_rx_mode() sees ndo_set_rx_mode_async, it schedules
netdev_rx_mode_work instead of calling the driver inline. The work
function takes two snapshots of each address list (uc/mc) under
the addr_lock, then drops the lock and calls the driver with the
work copies. After the driver returns, it reconciles the snapshots
back to the real lists under the lock.

Add netif_rx_mode_sync() to opportunistically execute the pending
workqueue update inline, so that rx mode changes are committed
before returning to userspace:
  - dev_change_flags (SIOCSIFFLAGS / RTM_NEWLINK)
  - dev_set_promiscuity
  - dev_set_allmulti
  - dev_ifsioc SIOCADDMULTI / SIOCDELMULTI
  - do_setlink (RTM_SETLINK)

Note that some deep hierarchies still do skip the lower updates via:
  - dev_uc_sync
  - dev_mc_sync

If we do end up hitting user-visible issues, we can add more calls to
netif_rx_mode_sync in specific places. But hopefully we should not,
the actual user-visible lists are still synced, it's that just HW state
that might be lagging.
