a076a860ac media: i2c: add I2C Address Translator (ATR) support
An ATR is a device that looks similar to an i2c-mux: it has an I2C
slave "upstream" port and N master "downstream" ports, and forwards
transactions from upstream to the appropriate downstream port. But it
is different in that the forwarded transaction has a different slave
address. The address used on the upstream bus is called the "alias"
and is (potentially) different from the physical slave address of the
downstream chip.

Add a helper file (just like i2c-mux.c for a mux or switch) to allow
implementing ATR features in a device driver. The helper takes care of
adapter creation/destruction and translates addresses at each transaction.

ad8258e877 bitmap patches for v6.5
Fixes for different bitmap pieces:
 
  - lib/test_bitmap: increment failure counter properly
 
    The tests that don't use expect_eq() macro to determine that a test is
    failured must increment failed_tests explicitly.
 
  - lib/bitmap: drop optimization of bitmap_{from,to}_arr64
 
    bitmap_{from,to}_arr64() optimization is overly optimistic on 32-bit LE
    architectures when it's wired to bitmap_copy_clear_tail().
 
  - nodemask: Drop duplicate check in for_each_node_mask()
 
    As the return value type of first_node() became unsigned, the node >= 0
    became unnecessary.
 
  - cpumask: fix function description kernel-doc notation
 
  - MAINTAINERS: Add bits.h to the BITMAP API record
  - MAINTAINERS: Add bitfield.h to the BITMAP API record
 
    Add linux/bits.h and linux/bitfield.h for visibility

028725e733 bootmem: remove the vmemmap pages from kmemleak in free_bootmem_page
commit dd0ff4d12d ("bootmem: remove the vmemmap pages from kmemleak in
put_page_bootmem") fix an overlaps existing problem of kmemleak.  But the
problem still existed when HAVE_BOOTMEM_INFO_NODE is disabled, because in
this case, free_bootmem_page() will call free_reserved_page() directly.

Fix the problem by adding kmemleak_free_part() in free_bootmem_page() when
HAVE_BOOTMEM_INFO_NODE is disabled.

Pull sh updates from Adrian Glaubitz:
 "Fix a compiler warning in the J2 probing code and a fix by Sergey
  Shtylyov to avoid using IRQ0 on SH3 and SH4 targets. Masahiro Yamada
  made some clean-up in the build system to address reports by the 0day
  bot.

  The most notable changes come from Artur Rojek who addressed a number
  of issues in the DMA code, in particular a fix for the DMA channel
  offset calculation that was introduced in in 7f47c7189b ("sh: dma:
  More legacy cpu dma chainsawing.") in 2012!

  Together with another change to correct the number of DMA channels for
  each SuperH SoC according to specification, Artur's series unbreaks
  the kernel on the SH7709 SoC allowing Linux to boot on the HP Jornada
  680 handheld again.

  Summary:

   - Provide unxlate_dev_mem_ptr() in asm/io.h

   - dma: Correct the number of DMA channels for SH7709

   - dma: Drop incorrect SH_DMAC_BASE1 definition for SH4

   - dma: Fix DMA channel offset calculation

   - Remove compiler flag duplication

   - Refactor header include path addition

   - Move build rule for cchips/hd6446x/ to arch/sh/Kbuild

73a3fcdaa7 f2fs update for 6.5-rc1
In this cycle, we've mainly investigated the zoned block device support along
 with patches such as correcting write pointers between f2fs and storage, adding
 asynchronous zone reset flow, and managing the number of open zones. Other than
 them, f2fs adds another mount option, "errors=x" to specify how to handle when
 it detects an unexpected behavior at runtime.
 
 Enhancement:
  - support errors=remount-ro|continue|panic mountoption
  - enforce some inode flag policies
  - allow .tmp compression given extensions
  - add some ioctls to manage the f2fs compression
  - improve looped node chain flow
  - avoid issuing small-sized discard commands during checkpoint
  - implement an asynchronous zone reset
 
 Bug fix:
  - fix deadlock in xattr and inode page lock
  - fix and add sanity check in some error paths
  - fix to avoid NULL pointer dereference f2fs_write_end_io() along with put_super
  - set proper flags to quota files
  - fix potential deadlock due to unpaired node_write lock use
  - fix over-estimating free section during FG GC
  - fix the wrong condition to determine atomic context
 
 As usual, also there are a number of patches having code refactoring and minor
 clean-ups.

01f23c5f15 usb: ch9: Replace bmSublinkSpeedAttr 1-element array with flexible array
Since commit 2d47c6956a ("ubsan: Tighten UBSAN_BOUNDS on GCC"),
UBSAN_BOUNDS no longer pretends 1-element arrays are unbounded. Walking
bmSublinkSpeedAttr will trigger a warning, so make it a proper flexible
array. Add a union to keep the struct size identical for userspace in
case anything was depending on the old size.

False positive warning was:

UBSAN: array-index-out-of-bounds in drivers/usb/host/xhci-hub.c:231:31 index 1 is out of range for type '__le32 [1]'

for this line of code:

	ssp_cap->bmSublinkSpeedAttr[offset++] = cpu_to_le32(attr);

04f2933d37 Scope-based Resource Management infrastructure
These are the first few patches in the Scope-based Resource Management
 series that introduce the infrastructure but not any conversions as of
 yet.
 
 Adding the infrastructure now allows multiple people to start using them.
 
 Of note is that Sparse will need some work since it doesn't yet
 understand this attribute and might have decl-after-stmt issues -- but I
 think that's being worked on.

a372d66af4 net: dsa: sja1105: always enable the send_meta options
incl_srcpt has the limitation, mentioned in commit b4638af888 ("net:
dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a
MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless
PTP RX timestamping is enabled.

The incl_srcpt option was initially unconditionally enabled, then that
changed with commit 42824463d3 ("net: dsa: sja1105: Limit use of
incl_srcpt to bridge+vlan mode"), then again with b4638af888 ("net:
dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that
it now needs to be always enabled, otherwise the driver does not have a
reliable source of information regarding source_port and switch_id for
link-local traffic (tag_8021q VLANs may be imprecise since now they
identify an entire bridging domain when ports are not standalone).

If we accept that PTP RX timestamping (and therefore, meta frame
generation) is always enabled in hardware, then that limitation could be
avoided and packets with any MAC DA can be properly received, because
meta frames do contain the original bytes from the MAC DA of their
associated link-local packet.

This change enables meta frame generation unconditionally, which also
has the nice side effects of simplifying the switch control path
(a switch reset is no longer required on hwtstamping settings change)
and the tagger data path (it no longer needs to be informed whether to
expect meta frames or not - it always does).

ba7bdec3cb net: Replace strlcpy with strscpy
strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
No return values were used, so direct replacement is safe.

406fb9eb19 firewire updates for 6.5-rc1
The updates consist of three parts; UAPI update, OHCI driver update, and
 several bug fixes.
 
 Firstly, the 1394 OHCI specification defines method to retrieve hardware
 time stamps for asynchronous communication, which was previously
 unavailable in user space. This change adds new events to the UAPI,
 allowing applications to retrieve the time when asynchronous packet are
 received and sent. The new events are tested in the breeding edge of
 libhinawa and look to work well. The new version of libhinawa will be
 released after current merge window is closed.
 
 * https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/
 
 Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI
 hardware, This change modernizes the driver by managed resource (devres)
 framework.
 
 Lastly, the rest of change is bug fixes for firewire-net and firewire-core.

b39aeb338a rdma: fix INFINIBAND_USER_ACCESS dependency
After a change to the bnxt_re driver, it fails to link when
CONFIG_INFINIBAND_USER_ACCESS is disabled:

  aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o: in function `bnxt_re_handler_BNXT_RE_METHOD_ALLOC_PAGE':
  ib_verbs.c:(.text+0xd64): undefined reference to `ib_uverbs_get_ucontext_file'
  aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x168): undefined reference to `uverbs_idr_class'
  aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x1a8): undefined reference to `uverbs_destroy_def_handler'

The problem is that the 'bnxt_re_uapi_defs' structure is built
unconditionally and references a couple of functions that are never
really called in this configuration but instead require other functions
that are left out.

Adding an #ifdef around the new code, or a Kconfig dependency would
address this problem, but adding the compile-time check inside of the
UAPI_DEF_CHAIN_OBJ_TREE_NAMED() macro seems best because that also
addresses the problem in other drivers that may run into the same
dependency.

e8069f5a8e ARM64:
* Eager page splitting optimization for dirty logging, optionally
   allowing for a VM to avoid the cost of hugepage splitting in the stage-2
   fault path.
 
 * Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
   services that live in the Secure world. pKVM intervenes on FF-A calls
   to guarantee the host doesn't misuse memory donated to the hyp or a
   pKVM guest.
 
 * Support for running the split hypervisor with VHE enabled, known as
   'hVHE' mode. This is extremely useful for testing the split
   hypervisor on VHE-only systems, and paves the way for new use cases
   that depend on having two TTBRs available at EL2.
 
 * Generalized framework for configurable ID registers from userspace.
   KVM/arm64 currently prevents arbitrary CPU feature set configuration
   from userspace, but the intent is to relax this limitation and allow
   userspace to select a feature set consistent with the CPU.
 
 * Enable the use of Branch Target Identification (FEAT_BTI) in the
   hypervisor.
 
 * Use a separate set of pointer authentication keys for the hypervisor
   when running in protected mode, as the host is untrusted at runtime.
 
 * Ensure timer IRQs are consistently released in the init failure
   paths.
 
 * Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
   (FEAT_EVT), as it is a register commonly read from userspace.
 
 * Erratum workaround for the upcoming AmpereOne part, which has broken
   hardware A/D state management.
 
 RISC-V:
 
 * Redirect AMO load/store misaligned traps to KVM guest
 
 * Trap-n-emulate AIA in-kernel irqchip for KVM guest
 
 * Svnapot support for KVM Guest
 
 s390:
 
 * New uvdevice secret API
 
 * CMM selftest and fixes
 
 * fix racy access to target CPU for diag 9c

 * Add support for CPU pinning in demand paging test
 
 * Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes
   included along the way

eded37770c kgdb patches for 6.5
Fairly small changes this cycle.
 
  * An additional static inline function when kgdb is not enabled to
    reduce boilerplate in arch files.
  * kdb will now handle input with linefeeds more like carriage return.
    This will make little difference for interactive use but can make

  * A couple of warning fixes.

f66066bc51 execve: always mark stack as growing down during early stack setup
While our user stacks can grow either down (all common architectures) or
up (parisc and the ia64 register stack), the initial stack setup when we
copy the argument and environment strings to the new stack at execve()
time is always done by extending the stack downwards.

But it turns out that in commit 8d7071af89 ("mm: always expand the
stack with the mmap write lock held"), as part of making the stack
growing code more robust, 'expand_downwards()' was now made to actually
check the vma flags:

	if (!(vma->vm_flags & VM_GROWSDOWN))
		return -EFAULT;

and that meant that this execve-time stack expansion started failing on
parisc, because on that architecture, the stack flags do not contain the
VM_GROWSDOWN bit.

At the same time the new check in expand_downwards() is clearly correct,
and simplified the callers, so let's not remove it.

The solution is instead to just codify the fact that yes, during
execve(), the stack grows down.  This not only matches reality, it ends
up being particularly simple: we already have special execve-time flags
for the stack (VM_STACK_INCOMPLETE_SETUP) and use those flags to avoid
page migration during this setup time (see vma_is_temporary_stack() and
invalid_migration_vma()).

So just add VM_GROWSDOWN to that set of temporary flags, and now our
stack flags automatically match reality, and the parisc stack expansion
works again.

Note that the VM_STACK_INCOMPLETE_SETUP bits will be cleared when the
stack is finalized, so we only add the extra VM_GROWSDOWN bit on
CONFIG_STACK_GROWSUP architectures (ie parisc) rather than adding it in
general.

228a27cf78 vhost: Allow worker switching while work is queueing
This patch drops the requirement that we can only switch workers if work
has not been queued by using RCU for the vq based queueing paths and a
mutex for the device wide flush.

We can also use this to support SIGKILL properly in the future where we
should exit almost immediately after getting that signal. With this
patch, when get_signal returns true, we can set the vq->worker to NULL
and do a synchronize_rcu to prevent new work from being queued to the
vhost_task that has been killed.

c1ecd8e950 vhost: allow userspace to create workers
For vhost-scsi with 3 vqs or more and a workload that tries to use
them in parallel like:

fio --filename=/dev/sdb  --direct=1 --rw=randrw --bs=4k \
--ioengine=libaio --iodepth=128  --numjobs=3

the single vhost worker thread will become a bottlneck and we are stuck
at around 500K IOPs no matter how many jobs, virtqueues, and CPUs are
used.

To better utilize virtqueues and available CPUs, this patch allows
userspace to create workers and bind them to vqs. You can have N workers
per dev and also share N workers with M vqs on that dev.

This patch adds the interface related code and the next patch will hook
vhost-scsi into it. The patches do not try to hook net and vsock into
the interface because:

1. multiple workers don't seem to help vsock. The problem is that with
only 2 virtqueues we never fully use the existing worker when doing
bidirectional tests. This seems to match vhost-scsi where we don't see
the worker as a bottleneck until 3 virtqueues are used.

2. net already has a way to use multiple workers.

dfab92f27c NFS client updates for Linux 6.5
Highlights include:
 
 Stable fixes and other bugfixes:
  - nfs: don't report STATX_BTIME in ->getattr
  - Revert "NFSv4: Retry LOCK on OLD_STATEID during delegation return"
    since it breaks NFSv4 state recovery.
  - NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION
  - Fix the NFSv4.2 xattr cache shrinker_id
  - Force a ctime update after a NFSv4.2 SETXATTR call
 
 Features and cleanups:
  - NFS and RPC over TLS client code from Chuck Lever.
  - Support for use of abstract unix socket addresses with the rpcbind
    daemon.
  - Sysfs API to allow shutdown of the kernel RPC client and prevent
    umount() hangs if the server is known to be permanently down.
  - XDR cleanups from Anna.

Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL updates from Dan Williams:
 "The highlights in terms of new functionality are support for the
  standard CXL Performance Monitor definition that appeared in CXL 3.0,
  support for device sanitization (wiping all data from a device),
  secure-erase (re-keying encryption of user data), and support for
  firmware update. The firmware update support is notable as it reuses
  the simple sysfs_upload interface to just cat(1) a blob to a sysfs
  file and pipe that to the device.

  Additionally there are a substantial number of cleanups and
  reorganizations to get ready for RCH error handling (RCH == Restricted
  CXL Host == current shipping hardware generation / pre CXL-2.0
  topologies) and type-2 (accelerator / vendor specific) devices.

  For vendor specific devices they implement a subset of what the
  generic type-3 (generic memory expander) driver expects. As a result
  the rework decouples optional infrastructure from the core driver
  context.

  For RCH topologies, where the specification working group did not want
  to confuse pre-CXL-aware operating systems, many of the standard
  registers are hidden which makes support standard bus features like
  AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
  the driver to help the PCI-AER core. Bjorn is on board with this
  direction but a late regression disocvery means the completion of this
  functionality needs to cook a bit longer, so it is code
  reorganizations only for now.

  Summary:

   - Add infrastructure for supporting background commands along with
     support for device sanitization and firmware update

   - Introduce a CXL performance monitoring unit driver based on the
     common definition in the specification.

   - Land some preparatory cleanup and refactoring for the anticipated
     arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1
     topology) error handling.

   - Rework CPU cache management with respect to region configuration
     (device hotplug or other dynamic changes to memory interleaving)

   - Fix region reconfiguration vs CXL decoder ordering rules"

408579cd62 mm: Update do_vmi_align_munmap() return semantics
Since do_vmi_align_munmap() will always honor the downgrade request on
the success, the callers no longer have to deal with confusing return
codes.  Since all callers that request downgrade actually want the lock
to be dropped, change the downgrade to an unlock request.

Note that the lock still needs to be held in read mode during the page
table clean up to avoid races with a map request.

Update do_vmi_align_munmap() to return 0 for success.  Clean up the
callers and comments to always expect the unlock to be honored on the
success path.  The error path will always leave the lock untouched.

As part of the cleanup, the wrapper function do_vmi_munmap() and callers
to the wrapper are also updated.

Merge patch series "riscv: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION"
Jisheng Zhang <jszhang@kernel.org> says:

When trying to run linux with various opensource riscv core on
resource limited FPGA platforms, for example, those FPGAs with less
than 16MB SDRAM, I want to save mem as much as possible. One of the
major technologies is kernel size optimizations, I found that riscv
does not currently support HAVE_LD_DEAD_CODE_DATA_ELIMINATION, which
passes -fdata-sections, -ffunction-sections to CFLAGS and passes the
--gc-sections flag to the linker.

This not only benefits my case on FPGA but also benefits defconfigs.
Here are some notable improvements from enabling this with defconfigs:

nommu_k210_defconfig:
   text    data     bss     dec     hex

9285914 3350052  483349 13119315 c82f53     after

patch1 and patch2 are clean ups.
patch3 fixes a typo.
patch4 finally enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for riscv.

* b4-shazam-merge:
  riscv: disable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for LLD
