3822a7c409 - Daniel Verkamp has contributed a memfd series ("mm/memfd: add 
F_SEAL_EXEC") which permits the setting of the memfd execute bit at
   memfd creation time, with the option of sealing the state of the X bit.
 
 - Peter Xu adds a patch series ("mm/hugetlb: Make huge_pte_offset()
   thread-safe for pmd unshare") which addresses a rare race condition
   related to PMD unsharing.
 
 - Several folioification patch serieses from Matthew Wilcox, Vishal
   Moola, Sidhartha Kumar and Lorenzo Stoakes
 
 - Johannes Weiner has a series ("mm: push down lock_page_memcg()") which
   does perform some memcg maintenance and cleanup work.
 
 - SeongJae Park has added DAMOS filtering to DAMON, with the series
   "mm/damon/core: implement damos filter".  These filters provide users
   with finer-grained control over DAMOS's actions.  SeongJae has also done
   some DAMON cleanup work.
 
 - Kairui Song adds a series ("Clean up and fixes for swap").
 
 - Vernon Yang contributed the series "Clean up and refinement for maple
   tree".
 
 - Yu Zhao has contributed the "mm: multi-gen LRU: memcg LRU" series.  It
   adds to MGLRU an LRU of memcgs, to improve the scalability of global
   reclaim.
 
 - David Hildenbrand has added some userfaultfd cleanup work in the
   series "mm: uffd-wp + change_protection() cleanups".
 
 - Christoph Hellwig has removed the generic_writepages() library
   function in the series "remove generic_writepages".
 
 - Baolin Wang has performed some maintenance on the compaction code in
   his series "Some small improvements for compaction".
 
 - Sidhartha Kumar is doing some maintenance work on struct page in his
   series "Get rid of tail page fields".
 
 - David Hildenbrand contributed some cleanup, bugfixing and
   generalization of pte management and of pte debugging in his series "mm:
   support __HAVE_ARCH_PTE_SWP_EXCLUSIVE on all architectures with swap
   PTEs".
 
 - Mel Gorman and Neil Brown have removed the __GFP_ATOMIC allocation
   flag in the series "Discard __GFP_ATOMIC".
 
 - Sergey Senozhatsky has improved zsmalloc's memory utilization with his
   series "zsmalloc: make zspage chain size configurable".
 
 - Joey Gouly has added prctl() support for prohibiting the creation of
   writeable+executable mappings.  The previous BPF-based approach had
   shortcomings.  See "mm: In-kernel support for memory-deny-write-execute
   (MDWE)".
 
 - Waiman Long did some kmemleak cleanup and bugfixing in the series
   "mm/kmemleak: Simplify kmemleak_cond_resched() & fix UAF".
 
 - T.J.  Alumbaugh has contributed some MGLRU cleanup work in his series
   "mm: multi-gen LRU: improve".
 
 - Jiaqi Yan has provided some enhancements to our memory error
   statistics reporting, mainly by presenting the statistics on a per-node
   basis.  See the series "Introduce per NUMA node memory error
   statistics".
 
 - Mel Gorman has a second and hopefully final shot at fixing a CPU-hog
   regression in compaction via his series "Fix excessive CPU usage during
   compaction".
 
 - Christoph Hellwig does some vmalloc maintenance work in the series
   "cleanup vfree and vunmap".
 
 - Christoph Hellwig has removed block_device_operations.rw_page() in ths
   series "remove ->rw_page".
 
 - We get some maple_tree improvements and cleanups in Liam Howlett's
   series "VMA tree type safety and remove __vma_adjust()".
 
 - Suren Baghdasaryan has done some work on the maintainability of our
   vm_flags handling in the series "introduce vm_flags modifier functions".
 
 - Some pagemap cleanup and generalization work in Mike Rapoport's series
   "mm, arch: add generic implementation of pfn_valid() for FLATMEM" and
   "fixups for generic implementation of pfn_valid()"
 
 - Baoquan He has done some work to make /proc/vmallocinfo and
   /proc/kcore better represent the real state of things in his series
   "mm/vmalloc.c: allow vread() to read out vm_map_ram areas".
 
 - Jason Gunthorpe rationalized the GUP system's interface to the rest of
   the kernel in the series "Simplify the external interface for GUP".
 
 - SeongJae Park wishes to migrate people from DAMON's debugfs interface
   over to its sysfs interface.  To support this, we'll temporarily be
   printing warnings when people use the debugfs interface.  See the series
   "mm/damon: deprecate DAMON debugfs interface".
 
 - Andrey Konovalov provided the accurately named "lib/stackdepot: fixes
   and clean-ups" series.
 
 - Huang Ying has provided a dramatic reduction in migration's TLB flush
   IPI rates with the series "migrate_pages(): batch TLB flushing".

06e1a81c48 A healthy mix of EFI contributions this time: 
- Performance tweaks for efifb earlycon by Andy
 
 - Preparatory refactoring and cleanup work in the efivar layer by Johan,
   which is needed to accommodate the Snapdragon arm64 laptops that
   expose their EFI variable store via a TEE secure world API.
 
 - Enhancements to the EFI memory map handling so that Xen dom0 can
   safely access EFI configuration tables (Demi Marie)
 
 - Wire up the newly introduced IBT/BTI flag in the EFI memory attributes
   table, so that firmware that is generated with ENDBR/BTI landing pads
   will be mapped with enforcement enabled.
 
 - Clean up how we check and print the EFI revision exposed by the
   firmware.
 
 - Incorporate EFI memory attributes protocol definition contributed by
   Evgeniy and wire it up in the EFI zboot code. This ensures that these
   images can execute under new and stricter rules regarding the default
   memory permissions for EFI page allocations. (More work is in progress
   here)

c538944d8e modules-6.3-rc1 
Nothing exciting at all for modules for v6.3. The biggest change is
 just the change of INSTALL_MOD_DIR from "extra" to "updates" which
 I found lingered for ages for no good reason while testing the CXL
 mock driver [0]. The CXL mock driver has no kconfig integration and requires
 building an external module... and re-building the *rest* of the production
 drivers. This mock driver when loaded but not the production ones will
 crash. All this crap can obviously be fixed by integrating kconfig
 semantics into such test module, however that's not desirable by
 the maintainer, and so sensible defaults must be used to ensure a
 default "make modules_install" will suffice for most distros which
 do not have a file like /etc/depmod.d/dist.conf with something like
 `search updates extra built-in`. Since most distros rely on kmod and
 since its inception the "updates" directory is always in the search
 path it makes more sense to use that than the "extra" which only
 *some* RH based systems rely on. All this stuff has been on linux-next
 for a while.
 
 For v6.4 I already have queued some initial work by Song Liu which gets
 us slowly going to a place where we *may* see a generic allocator for
 huge pages for module text to avoid direct map fragmentation *and*
 reduce iTLB pressure. That work is in its initial stages, no allocator
 work is done yet. This is all just prep work. Fortunately Thomas Gleixner
 has helped convince Song that modules *need* to be *requirement* if we
 are going to see any special allocator touch x86. So who knows... maybe
 around v6.5 we'll start seeing some *real* performance numbers of the
 effect of using huge pages for something other than eBPF toys.
 
 For v6.4 also, you may start seeing patches from Nick Alcock on different
 trees and modules-next which aims at extending kallsyms *eventually* to provide
 clearer address to symbol lookups. The claim is that this is a *great* *feature*
 tracing tools are dying to have so they can for instance disambiguate symbols as
 coming from modules or from other parts of the kernel. I'm still waiting to see
 proper too usage of such stuff, but *how* we lay this out is still being ironed
 out. Part of the initial work I've been pushing for is to help upkeep our
 modules build optimizations, so being mindful about the work by Masahiro Yamada
 on commit 8b41fc4454 ("kbuild: create modules.builtin without
 Makefile.modbuiltin or tristate.conf") which helps avoid traversing the build
 tree twice. After this commit we now rely on the MODULE_LICENSE() tag to
 determine in a *faster* way if something being built could be a module and
 we dump this into the modules.builtin so that modprobe can simply succeed
 if a module is known to already be built-in. The cleanup work on MODULE_LICENSE()
 simply stems to assist false positives from userspace for things as built-in
 when they *cannot ever* be modules as we don't even tristate the code as
 modular. This work also helps with the SPDX effort as some code is not clearly
 identified with a tag. In the *future*, once all *possible* modules are
 confirmed to have a respective SPDX tag, we *may* just be able to replace the
 MODULE_LICENSE() to instead be generated automatically through inference of
 the respective module SPDX tags.

   Please note that to have the -b option (BPF) working above one has to build
   with BUILD_BPF_SKEL=1.
 
   - Add more 'perf test' entries to test these new features.
 
 - Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
 
 - Add support for retire latency feature (pipeline stall of a instruction
   compared to the previous one, in cycles) present on some Intel processors.
 
 - Add 'perf c2c' report option to show false sharing with adjacent cachelines, to
   be used in machines with cacheline prefetching, where accesses to a cacheline
   brings the next one too.
 
 - Skip 'perf test bpf' when the required kernel-debuginfo package isn't installed.
 
 perf script:
 
 - Add 'cgroup' field for 'perf script' output:
 
   $ perf record --all-cgroups -- true
   $ perf script -F comm,pid,cgroup
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
 
 - Add support for showing branch speculation information in 'perf
   script' and in the 'perf report' raw dump (-D).
 
 perf record:
 
 - Fix 'perf record' segfault with --overwrite and --max-size.
 
 Intel PT:
 
 - Add support for synthesizing "cycle" events from Intel PT traces as we
   support "instruction" events when Intel PT CYC packets are available. This
   enables much more accurate profiles than when using the regular 'perf record -e
   cycles' (the default) when the workload lasts for very short periods (<10ms).
 
 - .plt symbol handling improvements, better handling IBT (in the past
   MPX) done in the context of decoding Intel PT processor traces, IFUNC
   symbols on x86_64, static executables, understanding .plt.got symbols on
   x86_64.
 
 - Add a 'perf test' to test symbol resolution, part of the .plt
   improvements series, this tests things like symbol size in contexts
   where only the symbol start is available (kallsyms), etc.
 
 - Better handle auxtrace/Intel PT data when using pipe mode (perf record sleep 1|perf report).
 
 - Fix symbol lookup with kcore with multiple segments match stext,
   getting the symbol resolution to just show DSOs as unknown.
 
 ARM:
 
 - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
   Macrocell v4).
 
 - Ensure ARM64 CoreSight timestamps don't go backwards.
 
 - Document that ARM64 SPE (Statistical Profiling Extension) is used with 'perf c2c/mem'.
 
 - Add raw decoding for ARM64 SPEv1.2 previous branch address.
 
 - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, TLB,
   cache, branch, PE utilization and instruction mix metrics.
 
 - Update decoder code for OpenCSD version 1.4, on ARM64 systems.
 
 - Fix command line auto-complete of CPU events on aarch64.
 
 perf test/bench:
 
 - Switch basic BPF filtering test to use syscall tracepoint to avoid the
   variable number of probes inserted when using the previous probe point
   (do_epoll_wait) that happens on different CPU architectures.
 
 - Fix DWARF unwind test by adding non-inline to expected function in a
   backtrace.
 
 - Use 'grep -c' where the longer form 'grep | wc -l' was being used.
 
 - Add getpid and execve benchmarks to 'perf bench syscall'.
 
 Miscellaneous:
 
 - Avoid d3-flame-graph package dependency in 'perf script flamegraph',
   making this feature more generally available.
 
 - Add JSON metric events to present CPI stall cycles in Power10.
 
 - Assorted improvements/refactorings on the JSON metrics parsing code.
 
 Build:
 
 - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, as
   several tests use tracepoints, those should be skipped.
 
 - More fallout fixes for the removal of tools/lib/traceevent/.
 
 - Fix build error when linking with libpfm.

9191423872 tracing: Fix race that causes a warning of corrupt ring buffer 
With the change that allows to read the "trace" file without disabling
 writing to the ring buffer, there was an integrity check of the ring
 buffer in the iterator read code, that expected the ring buffer to be
 write disabled. This caused the integrity check to trigger when stress
 reading the "trace" file while writing was happening.
 
 The integrity check is a bit aggressive (and has never triggered in
 practice). Change it so that it checks just the integrity of the linked
 pages without clearing the flags inside the pointers. This removes the
 warning that was being triggered.

192a5e0a19 LKMM updates for v6.3 
Documentation updates.
 
 Add read-modify-write sequences, which means that stronger primitives
 more consistently result in stronger ordering, while still remaining in
 the envelope of the hardware that supports Linux.
 
 Address, data, and control dependencies used to ignore data that was
 stored in temporaries.  This update extends these dependency chains to
 include unmarked intra-thread stores and loads.  Note that these unmarked
 stores and loads should not be concurrently accessed from multiple
 threads, and doing so will cause LKMM to flag such accesses as data races.

Merge tag '6.3-rc-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs client updates from Steve French:
 "The largest subset of this is from David Howells et al: making the
  cifs/smb3 driver pass iov_iters down to the lowest layers, directly to
  the network transport rather than passing lists of pages around,
  helping multiple areas:

   - Pin user pages, thereby fixing the race between concurrent DIO read
     and fork, where the pages containing the DIO read buffer may end up
     belonging to the child process and not the parent - with the result
     that the parent might not see the retrieved data.

   - cifs shouldn't take refs on pages extracted from non-user-backed
     iterators (eg. KVEC). With these changes, cifs will apply the
     appropriate cleanup.

   - Making it easier to transition to using folios in cifs rather than
     pages by dealing with them through BVEC and XARRAY iterators.

   - Allowing cifs to use the new splice function

  The remainder are:

   - fixes for stable, including various fixes for uninitialized memory,
     wrong length field causing mount issue to very old servers,
     important directory lease fixes and reconnect fixes

   - cleanups (unused code removal, change one element array usage, and
     a change form strtobool to kstrtobool, and Kconfig cleanups)

   - SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes

   - reconnect fixes

   - multichannel fixes, including improving channel allocation (to
     least used channel)

   - remove the last use of lock_page_killable by moving to
     folio_lock_killable"

9fc2f99030 NFSD 6.3 Release Notes 
Two significant security enhancements are part of this release:
 
 * NFSD's RPC header encoding and decoding, including RPCSEC GSS
   and gssproxy header parsing, has been overhauled to make it
   more memory-safe.
 
 * Support for Kerberos AES-SHA2-based encryption types has been
   added for both the NFS client and server. This provides a clean
   path for deprecating and removing insecure encryption types
   based on DES and SHA-1. AES-SHA2 is also FIPS-140 compliant, so
   that NFS with Kerberos may now be used on systems with fips
   enabled.
 
 In addition to these, NFSD is now able to handle crossing into an
 auto-mounted mount point on an exported NFS mount. A number of
 fixes have been made to NFSD's server-side copy implementation.
 
 RPC metrics have been converted to per-CPU variables. This helps
 reduce unnecessary cross-CPU and cross-node memory bus traffic,
 and significantly reduces noise when KCSAN is enabled.

   * Simplify ata_scsi_cmd_error_handler() code using the fact that

   * Several patches improving libata error handling. This is in
     preparation for supporting the command duration limits (CDL)
     feature. The changes allow handling corner cases of ATA NCQ errors
     which do not happen with regular drives but will be triggered with
     CDL drives. From Niklas.
 
   * Simplify the qc_fill_rtf operation, from me.
 
   * Improve SCSI command translation for the
     REPORT_SUPPORTED_OPERATION_CODES command, from me.
 
   * Cleanup of libata FUA handling. This falls short of enabling FUA for
     ATA drives that support it by default as there were concerns that
     old drives would break. The series howeverfixes several issues with
     the FUA support to ensure that FUA is reported as being supported
     only for drives that can handle all possible write cases (NCQ and
     non-NCQ). A check in the block layer is also added to ensure that we
     never see read FUA commands (current behavior). From me.
 
   * Several patches to move the old PARIDE (parallel port IDE) driver to
     libata as pata_parport. Given that this driver also needs protocol
     modules, the driver code resides in its own pata_parport directoy
     under drivers/ata. From Ondrej.

13e574b494 spi: Updates for v6.3 
This has been a fairly quiet release for SPI, though it is likely that
 the next release will have some big changes as there's some preparatory
 work for multiple chip select support gone in - the rest of the code is
 on the list but will need to be rebased onto -rc1.  Otherwise there's a couple
 of new tunables for chip select timings, some new devices and smaller
 device specific updates and fixes.
 
  - Support for configuring the hold and minimum inactive times for chip
    selects.
  - Beginnings of support for supporting devices which have multiple chip
    selects on a single device.
  - Support for newer Broadcom HSSPI and Intel controllers, Silicon Labs
    EM3581 and SI3210.
 
 There is a simple add/add conflict in MAINTAINERS with the I2C tree.
