MAINTAINERS: update KHO and LIVE UPDATE maintainers

Patch series "MAINTAINERS: update KHO and LIVE UPDATE entries".

This series contains some updates for the Kexec Handover (KHO) and Live
update entries. Patch 1 updates the maintainers list and adds the
liveupdate tree. Patches 2 and 3 clean up stale files in the list.


This patch (of 3):

I have been helping out with reviewing and developing KHO. I would also
like to help maintain it. Change my entry from R to M for KHO and live
update. Alex has been inactive for a while, so to avoid over-crowding the
KHO entry and to keep the information up-to-date, move his entry from M to
R.

We also now have a tree for KHO and live update at liveupdate/linux.git
where we plan to start maintaining those subsystems and start queuing the
patches. List that in the entries as well.

Merge tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs

Pull ntfs resurrection from Namjae Jeon:
"Ever since Kari Argillander’s 2022 report [1] regarding the state of
the ntfs3 driver, I have spent the last 4 years working to provide
full write support and current trends (iomap, no buffer head, folio),
enhanced performance, stable maintenance, utility support including
fsck for NTFS in Linux.

This new implementation is built upon the clean foundation of the
original read-only NTFS driver, adding:

- Write support:

Implemented full write support based on the classic read-only NTFS
driver. Added delayed allocation to improve write performance
through multi-cluster allocation and reduced fragmentation of the
cluster bitmap.

- iomap conversion:

Switched buffered IO (reads/writes), direct IO, file extent
mapping, readpages, and writepages to use iomap.

- Remove buffer_head:

Completely removed buffer_head usage by converting to folios. As a
result, the dependency on CONFIG_BUFFER_HEAD has been removed from
Kconfig.

- Stability improvements:

The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3.
All tests passed by ntfs3 are a complete subset of the tests passed
by this implementation. Added support for fallocate, idmapped
mounts, permissions, and more.

xfstests Results report:

Total tests run: 787
Passed : 326
Failed : 38
Skipped : 423

Failed tests breakdown:
- 34 tests require metadata journaling
- 4 other tests:
094: No unwritten extent concept in NTFS on-disk format
563: cgroup v2 aware writeback accounting not supported
631: RENAME_WHITEOUT support required
787: NFS delegation test"

- "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo)

- "cleanup the RAID5 XOR library" (Christoph Hellwig)

A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:

"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.

Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"

- "lib/list_sort: Clean up list_sort() scheduling workarounds"
(Kuan-Wei Chiu)

Clean up this library code by removing a hacky thing which was added
for UBIFS, which UBIFS doesn't actually need

Revert "fs: Remove NTFS classic"

This reverts commit 7ffa8f3d30236e0ab897c30bdb01224ff1fe1c89.

Reverts the removal of the classic read-only ntfs driver to
serve as the base for a new read-write ntfs implementation.
If we stack changes on top of the revert patch, It will significantly
reduce the diff size, making the review easier.

This revert intentionally excludes the restoration of Kconfig and
Makefile. The Kconfig and Makefile will be added back in the final patch
of this series, enabling the driver only after all features and
improvements have been applied.

Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core & protocols:

- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.

This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.

- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.

- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.

- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.

- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.

- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.

- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.

- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.

- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.

- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

- Reduce tcp socket size by one cache line.

- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.

- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.

- Improve xsk generic performances with cache-alignment-oriented
optimizations.

- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.

Driver API:

- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.

- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.

- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.

- Add helper to create, prepare and enable managed clocks.

Device drivers:

- Add Huawei hinic3 PF etherner driver.

- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.

- Add ethernet driver for MaxLinear MxL862xx switches

- Remove parallel-port Ethernet driver.

- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().

- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.

- Ethernet high-speed NICs:
- Broadcom (bnxt, bng):
- bnxt: add FW interface update to support FEC stats histogram
and NVRAM defragmentation
- bng: add TSO and H/W GRO support
- nVidia/Mellanox (mlx5):
- improve latency of channel restart operations, reducing the
used H/W resources
- add TSO support for UDP over GRE over VLAN
- add flow counters support for hardware steering (HWS) rules
- use a static memory area to store headers for H/W GRO,
leading to 12% RX tput improvement
- Intel (100G, ice, idpf):
- ice: reorganizes layout of Tx and Rx rings for cacheline
locality and utilizes __cacheline_group* macros on the new
layouts
- ice: introduces Synchronous Ethernet (SyncE) support
- Meta (fbnic):
- adds debugfs for firmware mailbox and tx/rx rings vectors

EDAC/r82600: Remove this obsolete driver

This driver supports the Radisys 82600 embedded chipset, which was used with
Pentium III-era CPUs. It is highly unlikely that it is still used. Besides
its own documentation, the only information I was able to find about the
R82600, after looking through many pages of Google results, was that it was
used in a Nokia 2G GSM base station.

The original author said:

"This was after Bluesmoke (watch was out-of-tree), and was pay of the first
set of in tree edac drivers (a fresh design as far as I remember).

This particular driver did apparently get used by Akamai quite heavily and
widely  but all ancient history now. The Radisys r82600 edac driver 
r82600_edac.c was closely related hardware from the same era, and can probably
go too (although being embedded hardware, it's possible its production
lifespan was considerably longer).

Tim."

The history of this driver is pretty amusing. It was marked broken in
2007 in

28f96eeafc89 ("drivers/edac-new-i82443bxgz-mc-driver: mark as broken").

It was then fixed in 2008 in

53a2fe5804e8 ("edac: make i82443bxgx_edac coexist with intel_agp"),

but the dependency on BROKEN was never removed. Given that this was never
fixed in the last ~18 years, it is obvious there is no demand for this driver.

net: ethernet: neterion: s2io: remove unused driver

The s2io driver supports Exar (formerly Neterion and S2io) PCI-X 10
Gigabit Ethernet cards. Hardware supporting PCI-X has not been
manufactured in years. On x86, it was quickly replaced by PCIe. While
it stuck around longer on POWER hardware, the last POWER hardware to
support it was POWER7, which is not supported by ppc64le Linux
distributions. The last supported mainstream ppc64 Linux distribution
was RHEL 7; while it is still supported under ELS, ELS is only
available for x86 and IBM Z. It is possible to use many PCI-X cards in
standard PCI slots (which are still available on new motherboards), but
it does not make sense to do so for 10 Gigabit Ethernet because the
maximum bandwidth of standard PCI is only 1067 Mbps. It is therefore
highly unlikely that this driver is still being used. Remove the
driver, and move the former maintainer to the CREDITS file (restoring
credit for the vxge driver, which was removed in commit f05643a0f60b
("eth: remove neterion/vxge").

net: remove HIPPI support and RoadRunner HIPPI driver

HIPPI has not been relevant for over two decades. It was rapidly
eclipsed by Fibre Channel, and even when it was new, it was
confined to very high-end hardware. The HIPPI code has only
received tree-wide changes and fixes by inspection in the entire
Git history. Remove HIPPI support and the rrunner HIPPI driver,
and move the former maintainer to the CREDITS file. Keep the
include/uapi/linux/if_hippi.h header because it is used by the TUN
code, and to avoid breaking userspace, however unlikely that may be.

nfc: MAINTAINERS: Orphan the NFC and look for new maintainers

NFC stack in Linux is in poor shape, with several bugs being discovered
last years via fuzzing, not much new development happening and limited
review and testing. It requires some more effort than drive-by reviews
I have been offering last one or two years.

I don't have much time nor business interests to keep looking at NFC,
so let's drop me from the maintainers to clearly indicate that more
hands are needed.
