e8cead54a6 ARM: dts: rockchip: Remove "amba" bus nodes from rv1108
The "amba" bus nodes wrapping all the DMA-330 nodes serve no useful
purpose, and certainly bear no relation at all to the actual underlying
interconnect topology. They appear to be cargo-cult copying from a
design misstep in the very early days of FDT adoption on ARM, which was
righted with the "arm,primecell" compatible, and the last trace of the
idea finally purged by commit 2ef7d5f342 ("ARM, ARM64: dts: drop
"arm,amba-bus" in favor of "simple-bus"").

As such, they can simply be removed and the DMA-330 nodes fitted into
the normal sort order.
The node names should be generic, so rename it to "dma-controller".

526f3f3b10 soc: ixp4xx/qmgr: Fix unused match warning
The kernel test robot found this inconsistency:

>> drivers/soc/ixp4xx/ixp4xx-npe.c:737:34: warning:
  'ixp4xx_npe_of_match' defined but not used [-Wunused-const-variable=]
     737 | static const struct of_device_id ixp4xx_npe_of_match[] = {

This is because the match is enclosed in the of_match_ptr()
which compiles into NULL when OF is disabled and this
is unnecessary.

Fix it by dropping of_match_ptr() around the match.

Patch series from Nick Hawkins:

"The GXP is the HPE BMC SoC that is used in the majority of HPE current
 generation servers. Traditionally the asic will last multiple
 generations of server before being replaced.

 Info about SoC:

  HPE GXP is the name of the HPE Soc. This SoC is used to implement many
  BMC features at HPE. It supports ARMv7 architecture based on the Cortex
  A9 core. It is capable of using an AXI bus to which a memory controller
  is attached. It has multiple SPI interfaces to connect boot flash and
  BIOS flash. It uses a 10/100/1000 MAC for network connectivity. It has
  multiple i2c engines to drive connectivity with a host infrastructure.
  The initial patches enable the watchdog and timer enabling the host to
  be able to boot."

     CPUs with and without an MMU.

   - A series to add a generic ticket spinlock that can be shared by
     most architectures with a working cmpxchg or ll/sc type atomic,
     including the conversion of riscv, csky and openrisc. This series
     is also a prerequisite for the loongarch64 architecture port that
     will come as a separate pull request.

   - A cleanup of some exported uapi header files to ensure they can be
     included from user space without relying on other kernel headers"

ecf0aa5317 Merge tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
 "This series has been 12 years in the making, it mostly finishes the
  work that was started with the founding of Linaro to clean up platform
  support in the kernel.

  The largest change here is a cleanup of the omap1 platform, which is
  the final ARM machine type to get converted to the common-clk
  subsystem. All the omap1 specific drivers are now made independent of
  the mach/*.h headers to allow the platform to be part of a generic
  ARMv4/v5 multiplatform kernel.

  The last bit that enables this support is still missing here while we
  wait for some last dependencies to make it into the mainline kernel
  through other subsystems.

  The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
  at the point of allowing multiplatform kernels, this work gets
  completed here along with a few additional cleanup. At the same time,
  the s3c24xx and s3c64xx are now deprecated and expected to get removed
  in the future.

  The PXA and OMAP1 bits are in a separate branch because of
  dependencies. Once both branches are merged, only the three Intel
  StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
  need separate kernels, and there are no plans to include these"

3378323bbb locking/lockref: Use try_cmpxchg64 in CMPXCHG_LOOP macro
Use try_cmpxchg64 instead of cmpxchg64 in CMPXCHG_LOOP macro.
x86 CMPXCHG instruction returns success in ZF flag, so this
change saves a compare after cmpxchg (and related move instruction
in front of cmpxchg). The main loop of lockref_get improves from:

  13:	48 89 c1             	mov    %rax,%rcx
  16:	48 c1 f9 20          	sar    $0x20,%rcx
  1a:	83 c1 01             	add    $0x1,%ecx
  1d:	48 89 ce             	mov    %rcx,%rsi
  20:	89 c1                	mov    %eax,%ecx
  22:	48 89 d0             	mov    %rdx,%rax

  35:	75 17                	jne    4e <lockref_get+0x4e>

to:

[ Michael Ellerman and Mark Rutland confirm that code generation on
  powerpc and arm64 respectively is also ok, even though they do not
  have a native arch_try_cmpxchg() implementation, and rely on the
  default fallback case    - Linus ]

babf0bb978 Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Dave Chinner:
 "This is a big update with lots of new code. The summary below them
  all, so I'll just touch on teh higlights. The two main new features
  are Large Extent Counts and Logged Attribute Replay - these are two
  new foundational features that we are building more complex future
  features on top of.

  For upcoming functionality, we need to be able to store hundreds of
  millions of xattrs per inode. The Large Extent Count feature removes
  the limits that prevent this scale of xattr storage, and while we were
  modifying the on disk extent count format we also increased the number
  of data extents we support per inode from 2^32 to 2^47.

  We also need to be able to modify xattrs as part of larger atomic
  transactions rather than as standalone transactions. The Logged
  Attribute Replay feature introduces the infrastructure that allows us
  to use intents to record the attribute modifications in the journal
  before we start them, hence allowing other atomic transactions to log
  attribute modification intents and then defer the actual modification
  to later. If we then crash, log recovery then guarantees that the
  attribute is replayed in the context of the atomic transaction that
  logged the intent.

  A significant chunk of the commits in this merge are for the base
  attribute replay functionality along with fixes, improvements and
  cleanups related to this new functioanlity. Allison deserves a big
  round of thanks for her ongoing work to get this functionality into
  XFS.

  There are also many other smaller changes and improvements, so overall
  this is one of the bigger XFS merge requests in some time.

  I will be following up next week with another smaller pull request -
  we already have another round of fixes and improvements to the logged
  attribute replay functionality just about ready to go. They'll soak
  and test over the next week, and I'll send a pull request for them
  near the end of the merge window.

  Summary:

   - support for printk message indexing.

   - large extent counts to provide support for up to 2^47 data extents
     and 2^32 attribute extents, allowing us to scale beyond 4 billion
     data extents to billions of xattrs per inode.

   - conversion of various flags fields to be consistently declared as
     unsigned bit fields.

   - improvements to realtime extent accounting and converts them to
     per-cpu counters to match all the other block and inode accounting.

   - reworks core log formatting code to reduce iterations, have a
     shorter, cleaner fast path and generally be easier to understand
     and maintain.

   - improvements to rmap btree searches that reduce overhead by up to
     30% resulting in xfs_scrub runtime reductions of 15%.

   - improvements to reflink that remove the size limitations in
     remapping operations and greatly reduce the size of transaction
     reservations.

   - reworks the minimum log size calculations to allow us to change
     transaction reservations without changing the minimum supported log
     size.

   - removal of quota warning support as it has never been used on
     Linux.

   - intent whiteouts to allow us to cancel intents that are completed
     entirely in memory rather than having use CPU and disk bandwidth
     formatting and writing them into the journal when it is not
     necessary. This makes rmap, reflink and extent freeing slightly
     more efficient, but provides massive improvements for....

   - Logged Attribute Replay feature support. This is a fundamental
     change to the way we modify attributes, laying the foundation for
     future integration of attribute modifications as part of other
     atomic transactional operations the filesystem performs.

   - Lots of cleanups and fixes for the logged attribute replay
     functionality"

 "Core
  ----

   - Support TCPv6 segmentation offload with super-segments larger than
     64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

   - Generalize skb freeing deferral to per-cpu lists, instead of
     per-socket lists.

   - Add a netdev statistic for packets dropped due to L2 address
     mismatch (rx_otherhost_dropped).

   - Continue work annotating skb drop reasons.

   - Accept alternative netdev names (ALT_IFNAME) in more netlink
     requests.

   - Add VLAN support for AF_PACKET SOCK_RAW GSO.

   - Allow receiving skb mark from the socket as a cmsg.

   - Enable memcg accounting for veth queues, sysctl tables and IPv6.

  BPF
  ---

   - Add libbpf support for User Statically-Defined Tracing (USDTs).

   - Speed up symbol resolution for kprobes multi-link attachments.

   - Support storing typed pointers to referenced and unreferenced
     objects in BPF maps.

   - Add support for BPF link iterator.

   - Introduce access to remote CPU map elements in BPF per-cpu map.

   - Allow middle-of-the-road settings for the
     kernel.unprivileged_bpf_disabled sysctl.

   - Implement basic types of dynamic pointers e.g. to allow for
     dynamically sized ringbuf reservations without extra memory copies.

  Protocols
  ---------

   - Retire port only listening_hash table, add a second bind table
     hashed by port and address. Avoid linear list walk when binding to
     very popular ports (e.g. 443).

   - Add bridge FDB bulk flush filtering support allowing user space to
     remove all FDB entries matching a condition.

   - Introduce accept_unsolicited_na sysctl for IPv6 to implement
     router-side changes for RFC9131.

   - Support for MPTCP path manager in user space.

   - Add MPTCP support for fallback to regular TCP for connections that
     have never connected additional subflows or transmitted
     out-of-sequence data (partial support for RFC8684 fallback).

   - Avoid races in MPTCP-level window tracking, stabilize and improve
     throughput.

   - Support lockless operation of GRE tunnels with seq numbers enabled.

   - WiFi support for host based BSS color collision detection.

   - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

   - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

   - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).

   - Allow matching on the number of VLAN tags via tc-flower.

   - Add tracepoint for tcp_set_ca_state().

  Driver API
  ----------

   - Improve error reporting from classifier and action offload.

   - Add support for listing line cards in switches (devlink).

   - Add helpers for reporting page pool statistics with ethtool -S.

   - Add support for reading clock cycles when using PTP virtual clocks,
     instead of having the driver convert to time before reporting. This
     makes it possible to report time from different vclocks.

   - Support configuring low-latency Tx descriptor push via ethtool.

   - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

  New hardware / drivers

537e62c865 Merge tag 'printk-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:

 - Offload writing printk() messages on consoles to per-console
   kthreads.

   It prevents soft-lockups when an extensive amount of messages is
   printed. It was observed, for example, during boot of large systems
   with a lot of peripherals like disks or network interfaces.

   It prevents live-lockups that were observed, for example, when
   messages about allocation failures were reported and a CPU handled
   consoles instead of reclaiming the memory. It was hard to solve even
   with rate limiting because it would need to take into account the
   amount of messages and the speed of all consoles.

   It is a must to have for real time. Otherwise, any printk() might
   break latency guarantees.

   The per-console kthreads allow to handle each console on its own
   speed. Slow consoles do not longer slow down faster ones. And
   printk() does not longer unpredictably slows down various code paths.

   There are situations when the kthreads are either not available or
   not reliable, for example, early boot, suspend, or panic. In these
   situations, printk() uses the legacy mode and tries to handle
   consoles immediately.

 - Add documentation for the printk index.

2e17ce1106 Merge tag 'slab-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:

 - Conversion of slub_debug stack traces to stackdepot, allowing more
   useful debugfs-based inspection for e.g. memory leak debugging.
   Allocation and free debugfs info now includes full traces and is
   sorted by the unique trace frequency.

   The stackdepot conversion was already attempted last year but
   reverted by ae14c63a9f. The memory overhead (while not actually
   enabled on boot) has been meanwhile solved by making the large
   stackdepot allocation dynamic. The xfstest issues haven't been
   reproduced on current kernel locally nor in -next, so the slab cache
   layout changes that originally made that bug manifest were probably
   not the root cause.

 - Refactoring of dma-kmalloc caches creation.

 - Trivial cleanups such as removal of unused parameters, fixes and
   clarifications of comments.

 - Hyeonggon Yoo joins as a reviewer.

caa2898416 linux/types.h: reinstate "__bitwise__" macro for user space use
Commit c724c866bb ("linux/types.h: remove unnecessary __bitwise__")
was right that there are no users of __bitwise__ in the kernel, but it
turns out there are user space users of it that do expect it.

It is, after all, in the uapi directory, so user space usage is to be
expected.

Instead of reverting the commit completely, let's just clarify the
situation so that it doesn't happen again, and have some in-code
explanations for why that "__bitwise__" still exists.

Commit b2a90f4fcb ("media: lirc: remove unused lirc features") removed
feature flags which were never implemented, but they are still used by
the lirc daemon went built from source.

Reinstate these symbols in order not to break the lirc build.

1a23accae8 ARM: ixp4xx: Consolidate Kconfig fixing issue
The IXP4xx Kconfig we ended up with for mach-ixp4xx creates
as kismet warning:

   WARNING: unmet direct dependencies detected for GPIO_IXP4XX
     Depends on [n]: GPIOLIB [=y] && HAS_IOMEM [=y] && ARCH_IXP4XX [=y] && OF [=n]
     Selected by [y]:
     - ARCH_IXP4XX [=y] && <choice>

This is because it is possible to select ARCH_IXP4XX witout
OF while that selects the GPIO driver that now depends on
OF.

Fix this by creating a single ARCH_IXP4XX kconfig that selects
USE_OF.

Pull iomap updates from Darrick Wong:
 "There's a couple of corrections sent in by Andreas for some accounting
  errors.

  The biggest change this time around is that writeback errors longer
  clear pageuptodate nor does XFS invalidate the page cache anymore.
  This brings XFS (and gfs2/zonefs) behavior in line with every other
  Linux filesystem driver, and fixes some UAF bugs that only cropped up
  after willy turned on multipage folios for XFS in 5.18-rc1.

  Regrettably, it took all the way to the end of the 5.18 cycle to find
  the source of these bugs and reach a consensus that XFS' writeback
  failure behavior from 20 years ago is no longer necessary.

  Summary:

   - Fix a couple of accounting errors in the buffered io code.

   - Discontinue the practice of marking folios !uptodate and
     invalidating them when writeback fails.

     This fixes some UAF bugs when multipage folios are enabled, and
     brings the behavior of XFS/gfs/zonefs into alignment with the
     behavior of all the other Linux filesystems"
