ubsan: integer-overflow: depend on BROKEN to keep this out of CI
wifi: iwlwifi: mld: Work around Clang loop unrolling bug
|
|
While not yet in the tree, there is a proposed patch[1] that was
depending on the prior behavior of _DEFINE_FLEX, which did not have an
explicit initializer. Provide this via __DEFINE_FLEX now, which can also
have attributes applied (e.g. __uninitialized).
Examples of the resulting initializer behaviors can be seen here:

Pull MM updates from Andrew Morton:
- "Add folio_mk_pte()" from Matthew Wilcox simplifies the act of
creating a pte which addresses the first page in a folio and reduces
the amount of plumbing which architecture must implement to provide
this.
- "Misc folio patches for 6.16" from Matthew Wilcox is a shower of
largely unrelated folio infrastructure changes which clean things up
and better prepare us for future work.
- "memory,x86,acpi: hotplug memory alignment advisement" from Gregory
Price adds early-init code to prevent x86 from leaving physical
memory unused when physical address regions are not aligned to memory
block size.
- "mm/compaction: allow more aggressive proactive compaction" from
Michal Clapinski provides some tuning of the (sadly, hard-coded (more
sadly, not auto-tuned)) thresholds for our invokation of proactive
compaction. In a simple test case, the reduction of a guest VM's
memory consumption was dramatic.
- "Minor cleanups and improvements to swap freeing code" from Kemeng
Shi provides some code cleaups and a small efficiency improvement to
this part of our swap handling code.
- "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin
adds the ability for a ptracer to modify syscalls arguments. At this
time we can alter only "system call information that are used by
strace system call tampering, namely, syscall number, syscall
arguments, and syscall return value.
This series should have been incorporated into mm.git's "non-MM"
branch, but I goofed.
- "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from
Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl
against /proc/pid/pagemap. This permits CRIU to more efficiently get
at the info about guard regions.
- "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan
implements that fix. No runtime effect is expected because
validate_page_before_insert() happens to fix up this error.
- "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David
Hildenbrand basically brings uprobe text poking into the current
decade. Remove a bunch of hand-rolled implementation in favor of
using more current facilities.
- "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman
Khandual provides enhancements and generalizations to the pte dumping
code. This might be needed when 128-bit Page Table Descriptors are
enabled for ARM.
- "Always call constructor for kernel page tables" from Kevin Brodsky
ensures that the ctor/dtor is always called for kernel pgtables, as
it already is for user pgtables.
This permits the addition of more functionality such as "insert hooks
to protect page tables". This change does result in various
architectures performing unnecesary work, but this is fixed up where
it is anticipated to occur.
- "Rust support for mm_struct, vm_area_struct, and mmap" from Alice
Ryhl adds plumbing to permit Rust access to core MM structures.
- "fix incorrectly disallowed anonymous VMA merges" from Lorenzo
Stoakes takes advantage of some VMA merging opportunities which we've
been missing for 15 years.
- "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from
SeongJae Park optimizes process_madvise()'s TLB flushing.
Instead of flushing each address range in the provided iovec, we
batch the flushing across all the iovec entries. The syscall's cost
was approximately halved with a microbenchmark which was designed to
load this particular operation.
- "Track node vacancy to reduce worst case allocation counts" from
Sidhartha Kumar makes the maple tree smarter about its node
preallocation.
stress-ng mmap performance increased by single-digit percentages and
the amount of unnecessarily preallocated memory was dramaticelly
reduced.
- "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes
a few unnecessary things which Baoquan noted when reading the code.
- ""Enhance sysfs handling for memory hotplug in weighted interleave"
from Rakie Kim "enhances the weighted interleave policy in the memory
management subsystem by improving sysfs handling, fixing memory
leaks, and introducing dynamic sysfs updates for memory hotplug
support". Fixes things on error paths which we are unlikely to hit.
- "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory"
from SeongJae Park introduces new DAMOS quota goal metrics which
eliminate the manual tuning which is required when utilizing DAMON
for memory tiering.
- "mm/vmalloc.c: code cleanup and improvements" from Baoquan He
provides cleanups and small efficiency improvements which Baoquan
found via code inspection.
- "vmscan: enforce mems_effective during demotion" from Gregory Price
changes reclaim to respect cpuset.mems_effective during demotion when
possible. because presently, reclaim explicitly ignores
cpuset.mems_effective when demoting, which may cause the cpuset
settings to violated.
This is useful for isolating workloads on a multi-tenant system from
certain classes of memory more consistently.
- "Clean up split_huge_pmd_locked() and remove unnecessary folio
pointers" from Gavin Guo provides minor cleanups and efficiency gains
in in the huge page splitting and migrating code.
- "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache
for `struct mem_cgroup', yielding improved memory utilization.
- "add max arg to swappiness in memory.reclaim and lru_gen" from
Zhongkun He adds a new "max" argument to the "swappiness=" argument
for memory.reclaim MGLRU's lru_gen.
This directs proactive reclaim to reclaim from only anon folios
rather than file-backed folios.
- "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the
first step on the path to permitting the kernel to maintain existing
VMs while replacing the host kernel via file-based kexec. At this
time only memblock's reserve_mem is preserved.
- "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides
and uses a smarter way of looping over a pfn range. By skipping
ranges of invalid pfns.
- "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via
cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning
when a task is pinned a single NUMA mode.
Dramatic performance benefits were seen in some real world cases.
- "JFS: Implement migrate_folio for jfs_metapage_aops" from Shivank
Garg addresses a warning which occurs during memory compaction when
using JFS.
- "move all VMA allocation, freeing and duplication logic to mm" from
Lorenzo Stoakes moves some VMA code from kernel/fork.c into the more
appropriate mm/vma.c.
- "mm, swap: clean up swap cache mapping helper" from Kairui Song
provides code consolidation and cleanups related to the folio_index()
function.
- "mm/gup: Cleanup memfd_pin_folios()" from Vishal Moola does that.
- "memcg: Fix test_memcg_min/low test failures" from Waiman Long
addresses some bogus failures which are being reported by the
test_memcontrol selftest.
- "eliminate mmap() retry merge, add .mmap_prepare hook" from Lorenzo
Stoakes commences the deprecation of file_operations.mmap() in favor
of the new file_operations.mmap_prepare().
The latter is more restrictive and prevents drivers from messing with
things in ways which, amongst other problems, may defeat VMA merging.
- "memcg: decouple memcg and objcg stocks"" from Shakeel Butt decouples
the per-cpu memcg charge cache from the objcg's one.
This is a step along the way to making memcg and objcg charging
NMI-safe, which is a BPF requirement.
- "mm/damon: minor fixups and improvements for code, tests, and
documents" from SeongJae Park is yet another batch of miscellaneous
DAMON changes. Fix and improve minor problems in code, tests and
documents.
- "memcg: make memcg stats irq safe" from Shakeel Butt converts memcg
stats to be irq safe. Another step along the way to making memcg
charging and stats updates NMI-safe, a BPF requirement.
- "Let unmap_hugepage_range() and several related functions take folio
instead of page" from Fan Ni provides folio conversions in the
hugetlb code.

Pull compiler version requirement update from Arnd Bergmann:
"Require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other
architectures to the same version. gcc-8 is used is Debian 10 and Red
Hat Enterprise Linux 8, both of which are still supported, and
binutils 2.30 is the oldest corresponding version on those.
Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as
the system compiler but additionally include toolchains that remain
supported.
With the new minimum toolchain versions, a number of workarounds for
older versions can be dropped, in particular on x86_64 and arm64.
Importantly, the updated compiler version allows removing two of the
five remaining gcc plugins, as support for sancov and structeak
features is already included in modern compiler versions.
I tried collecting the known changes that are possible based on the
new toolchain version, but expect that more cleanups will be possible.
Since this touches multiple architectures, I merged the patches
through the asm-generic tree."

Pull automount updates from Al Viro:
"Automount wart removal
A bunch of odd boilerplate gone from instances - the reason for
those was the need to protect the yet-to-be-attched mount from
mark_mounts_for_expiry() deciding to take it out.
But that's easy to detect and take care of in mark_mounts_for_expiry()
itself; no need to have every instance simulate mount being busy by
grabbing an extra reference to it, with finish_automount() undoing
that once it attaches that mount.
Should've done it that way from the very beginning... This is a
flagday change, thankfully there are very few instances.

Pull EFI updates from Ard Biesheuvel:
"Not a lot going on in the EFI tree this cycle. The only thing that
stands out is the new support for SBAT metadata, which was a bit
contentious when it was first proposed, because in the initial
incarnation, it would have required us to maintain a revocation index,
and bump it each time a vulnerability affecting UEFI secure boot got
fixed. This was shot down for obvious reasons.
This time, only the changes needed to emit the SBAT section into the
PE/COFF image are being carried upstream, and it is up to the distros
to decide what to put in there when creating and signing the build.
This only has the EFI zboot bits (which the distros will be using for
arm64); the x86 bzImage changes should be arriving next cycle,
presumably via the -tip tree.
Summary:
- Add support for emitting a .sbat section into the EFI zboot image,
so that downstreams can easily include revocation metadata in the
signed EFI images
- Align PE symbolic constant names with other projects
- Bug fix for the efi_test module
- Log the physical address and size of the EFI memory map when
failing to map it
- A kerneldoc fix for the EFI stub code"

Pull clk updates from Stephen Boyd:
"This has been a semi-quiet cycle. The core framework remains unchanged
this time around.
In terms of shiny new code though, we have support for the SpacemiT K1
SoC, Sophgo SG2044, and T-HEAD TH1520 VO clk drivers joining the usual
silicon players like Qualcomm, Samsung, Allwinner, and Renesas.
Surprisingly, the Qualcomm pile was smaller than usual but that is
likely because they put one SoC support inside a driver for a
different SoC that is very similar.
Other than all those new clk drivers there are the usual clk data
updates to fix parents, frequency tables, and add missing clks along
with some Kconfig changes to make compile testing simpler and even
more DT binding conversions to boot.
The exciting part is still the new SoC support like SpacemiT and
Sophgo support though, which really dominate the diffstat because they
introduce a whole new silicon vendor clk driver.
New Drivers:
- Camera clock controller driver for Qualcomm QCS8300
- DE (display engine) 3.3 clocks on Allwinner H616
- Samsung ExynosAutov920 CPU cluster CL0, CL1 and CL2 clock controllers
- Video Output (VO) subsystem clk controller in the T-HEAD TH1520 SoC
- Clock driver for Sophgo SG2044
- Clock driver for SpacemiT K1 SoC
- Renesas RZ/V2N (R9A09G056) SoC clk driver
Updates:
- Correct data in various SoC clk drivers
- Allow clkaN to be optional in the Qualcomm RPMh clock controller
driver if command db doesn't define it
- Change Kconfig options to not enable by default during compile
testing
- Add missing clks in various SoC clk drivers
- Remove some duplicate clk DT bindings and convert some more to
YAML"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Have module addresses get updated in the persistent ring buffer
The addresses of the modules from the previous boot are saved in the
persistent ring buffer. If the same modules are loaded and an address
is in the old buffer points to an address that was both saved in the
persistent ring buffer and is loaded in memory, shift the address to
point to the address that is loaded in memory in the trace event.
- Print function names for irqs off and preempt off callsites
When ignoring the print fmt of a trace event and just printing the
fields directly, have the fields for preempt off and irqs off events
still show the function name (via kallsyms) instead of just showing
the raw address.
- Clean ups of the histogram code
The histogram functions saved over 800 bytes on the stack to process
events as they come in. Instead, create per-cpu buffers that can hold
this information and have a separate location for each context level
(thread, softirq, IRQ and NMI).
Also add some more comments to the code.
- Add "common_comm" field for histograms
Add "common_comm" that uses the current->comm as a field in an event
histogram and acts like any of the other fields of the event.
- Show "subops" in the enabled_functions file
When the function graph infrastructure is used, a subsystem has a
"subops" that it attaches its callback function to. Instead of the
enabled_functions just showing a function calling the function that
calls the subops functions, also show the subops functions that will
get called for that function too.
- Add "copy_trace_marker" option to instances
There are cases where an instance is created for tooling to write
into, but the old tooling has the top level instance hardcoded into
the application. New tools want to consume the data from an instance
and not the top level buffer. By adding a copy_trace_marker option,
whenever the top instance trace_marker is written into, a copy of it
is also written into the instance with this option set. This allows
new tools to read what old tools are writing into the top buffer.
If this option is cleared by the top instance, then what is written
into the trace_marker is not written into the top instance. This is a
way to redirect the trace_marker writes into another instance.
- Have tracepoints created by DECLARE_TRACE() use trace_<name>_tp()
If a tracepoint is created by DECLARE_TRACE() instead of
TRACE_EVENT(), then it will not be exposed via tracefs. Currently
there's no way to differentiate in the kernel the tracepoint
functions between those that are exposed via tracefs or not. A
calling convention has been made manually to append a "_tp" prefix
for events created by DECLARE_TRACE(). Instead of doing this
manually, force it so that all DECLARE_TRACE() events have this
notation.
- Use __string() for task->comm in some sched events
Instead of hardcoding the comm to be TASK_COMM_LEN in some of the
scheduler events use __string() which makes it dynamic. Note, if
these events are parsed by user space it they may break, and the
event may have to be converted back to the hardcoded size.
- Have function graph "depth" be unsigned to the user
Internally to the kernel, the "depth" field of the function graph
event is signed due to -1 being used for end of boundary. What
actually gets recorded in the event itself is zero or positive.
Reflect this to user space by showing "depth" as unsigned int and be
consistent across all events.
- Allow an arbitrary long CPU string to osnoise_cpus_write()
The filtering of which CPUs to write to can exceed 256 bytes. If a
machine has 256 CPUs, and the filter is to filter every other CPU,
the write would take a string larger than 256 bytes. Instead of using
a fixed size buffer on the stack that is 256 bytes, allocate it to
handle what is passed in.
- Stop having ftrace check the per-cpu data "disabled" flag
The "disabled" flag in the data structure passed to most ftrace
functions is checked to know if tracing has been disabled or not.
This flag was added back in 2008 before the ring buffer had its own
way to disable tracing. The "disable" flag is now not always set when
needed, and the ring buffer flag should be used in all locations
where the disabled is needed. Since the "disable" flag is redundant
and incorrect, stop using it. Fix up some locations that use the
"disable" flag to use the ring buffer info.
- Use a new tracer_tracing_disable/enable() instead of data->disable
flag
There's a few cases that set the data->disable flag to stop tracing,
but this flag is not consistently used. It is also an on/off switch
where if a function set it and calls another function that sets it,
the called function may incorrectly enable it.
Use a new trace_tracing_disable() and tracer_tracing_enable() that
uses a counter and can be nested. These use the ring buffer flags
which are always checked making the disabling more consistent.
- Save the trace clock in the persistent ring buffer
Save what clock was used for tracing in the persistent ring buffer
and set it back to that clock after a reboot.
- Remove unused reference to a per CPU data pointer in mmiotrace
functions
- Remove unused buffer_page field from trace_array_cpu structure
- Remove more strncpy() instances

Pull driver core updates from Greg KH:
"Here are the driver core / kernfs changes for 6.16-rc1.
Not a huge number of changes this development cycle, here's the
summary of what is included in here:
- kernfs locking tweaks, pushing some global locks down into a per-fs
image lock
- rust driver core and pci device bindings added for new features.
- sysfs const work for bin_attributes.
The final churn of switching away from and removing the
transitional struct members, "read_new", "write_new" and
"bin_attrs_new" will come after the merge window to avoid
unnecesary merge conflicts.
- auxbus device creation helpers added
- fauxbus fix for creating sysfs files after the probe completed
properly
- other tiny updates for driver core things.
All of these have been in linux-next for over a week with no reported
issues"

Pull kvm updates from Paolo Bonzini:
"As far as x86 goes this pull request "only" includes TDX host support.
Quotes are appropriate because (at 6k lines and 100+ commits) it is
much bigger than the rest, which will come later this week and
consists mostly of bugfixes and selftests. s390 changes will also come
in the second batch.
ARM:
- Add large stage-2 mapping (THP) support for non-protected guests
when pKVM is enabled, clawing back some performance.
- Enable nested virtualisation support on systems that support it,
though it is disabled by default.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE
and protected modes.
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. While this has no functional
impact, it ensures correctness of emulation (the data is
automatically extracted from the published JSON files), and helps
dealing with the evolution of the architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.
LoongArch:
- Don't flush tlb if the host supports hardware page table walks.
- Add KVM selftests support.
RISC-V:
- Add vector registers to get-reg-list selftest
- VCPU reset related improvements
- Remove scounteren initialization from VCPU reset
- Support VCPU reset from userspace using set_mpstate() ioctl
x86:
- Initial support for TDX in KVM.
This finally makes it possible to use the TDX module to run
confidential guests on Intel processors. This is quite a large
series, including support for private page tables (managed by the
TDX module and mirrored in KVM for efficiency), forwarding some
TDVMCALLs to userspace, and handling several special VM exits from
the TDX module.
This has been in the works for literally years and it's not really
possible to describe everything here, so I'll defer to the various
merge commits up to and including commit 7bcf7246c42a ('Merge
branch 'kvm-tdx-finish-initial' into HEAD')"

Pull networking updates from Paolo Abeni:
"Core:
- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.
- Convert queue related netlink ops to instance lock, reducing again
the scope of the RTNL lock. This improves the control plane
scalability.
- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.
Netfilter:
- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools still
use this interface.
- Implement support for wildcard netdevice in netdev basechain and
flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better
introspection.
BPF:
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.
Protocols:
- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the
single flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API:
- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.
Tests and tooling:
- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers:
- OpenVPN virtual driver: offload OpenVPN data channels processing to
the kernel-space, increasing the data transfer throughput WRT the
user-space implementation.
- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
- Broadcom asp-v3.0 ethernet driver.

Pull arm64 updates from Will Deacon:
"The headline feature is the re-enablement of support for Arm's
Scalable Matrix Extension (SME) thanks to a bumper crop of fixes
from Mark Rutland.
If matrices aren't your thing, then Ryan's page-table optimisation
work is much more interesting.
Summary:
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls
- Fix a node refcount imbalance in the PSCI device-tree code
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
guests can reliably query the underlying CPU types from the VMM
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code
Entry code:
- Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
selected
Memory management:
- Prevent BSS exports from being used by the early PI code
- Propagate level and stride information to the low-level TLB
invalidation routines when operating on hugetlb entries
- Use the page-table contiguous hint for vmap() mappings with
VM_ALLOW_HUGE_VMAP where possible
- Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
and hook this up on arm64 so that the trailing DSB (used to publish
the updates to the hardware walker) can be deferred until the end
of the mapping operation
- Extend mmap() randomisation for 52-bit virtual addresses (on par
with 48-bit addressing) and remove limited support for
randomisation of the linear map
Perf and PMUs:
- Add support for probing the CMN-S3 driver using ACPI
- Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers
Selftests:
- Fix FPSIMD and SME tests to align with the freshly re-enabled SME
support
- Fix default setting of the OUTPUT variable so that tests are
installed in the right location
vDSO:
- Replace raw counter access from inline assembly code with a call to
the the __arch_counter_get_cntvct() helper function
Miscellaneous:
- Add some missing header inclusions to the CCA headers
- Rework rendering of /proc/cpuinfo to follow the x86-approach and
avoid repeated buffer expansion (the user-visible format remains
identical)
- Remove redundant selection of CONFIG_CRC32
- Extend early error message when failing to map the device-tree
blob"

Pull nfsd updates from Chuck Lever:
"The marquee feature for this release is that the limit on the maximum
rsize and wsize has been raised to 4MB. The default remains at 1MB,
but risk-seeking administrators now have the ability to try larger I/O
sizes with NFS clients that support them. Eventually the default
setting will be increased when we have confidence that this change
will not have negative impact.
With v6.16, NFSD now has its own debugfs file system where we can add
experimental features and make them available outside of our
development community without impacting production deployments. The
first experimental setting added is one that makes all NFS READ
operations use vfs_iter_read() instead of the NFSD splice actor. The
plan is to eventually retire the splice actor, as that will enable a
number of new capabilities such as the use of struct bio_vec from the
top to the bottom of the NFSD stack.
Jeff Layton contributed a number of observability improvements. The
use of dprintk() in a number of high-traffic code paths has been
replaced with static trace points.
This release sees the continuation of efforts to harden the NFSv4.2
COPY operation. Soon, the restriction on async COPY operations can be
lifted.
Many thanks to the contributors, reviewers, testers, and bug reporters
who participated during the v6.16 development cycle"

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw

Pull integrity updates from Mimi Zohar:
"Carrying the IMA measurement list across kexec is not a new feature,
but is updated to address a couple of issues:
- Carrying the IMA measurement list across kexec required knowing
apriori all the file measurements between the "kexec load" and
"kexec execute" in order to measure them before the "kexec load".
Any delay between the "kexec load" and "kexec exec" exacerbated the
problem.
- Any file measurements post "kexec load" were not carried across
kexec, resulting in the measurement list being out of sync with the
TPM PCR.
With these changes, the buffer for the IMA measurement list is still
allocated at "kexec load", but copying the IMA measurement list is
deferred to after quiescing the TPM.
Two new kexec critical data records are defined"

Pull cgroup updates from Tejun Heo:
- cgroup rstat shared the tracking tree across all controllers with the
rationale being that a cgroup which is using one resource is likely
to be using other resources at the same time (ie. if something is
allocating memory, it's probably consuming CPU cycles).
However, this turned out to not scale very well especially with memcg
using rstat for internal operations which made memcg stat read and
flush patterns substantially different from other controllers. JP
Kobryn split the rstat tree per controller.
- cgroup BPF support was hooking into cgroup init/exit paths directly.
Convert them to use a notifier chain instead so that other usages can
be added easily. The two of the patches which implement this are
mislabeled as belonging to sched_ext instead of cgroup. Sorry.

Pull sysctl updates from Joel Granados:
- Move kern_table members out of kernel/sysctl.c
Moved a subset (tracing, panic, signal, stack_tracer and sparc) out
of the kern_table array. The goal is for kern_table to only have
sysctl elements. All this increases modularity by placing the
ctl_tables closer to where they are used while reducing the chances
of merge conflicts in kernel/sysctl.c.
- Fixed sysctl unit test panic by relocating it to selftests
* tag 'sysctl-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl:
sysctl: Close test ctl_headers with a for loop
sysctl: call sysctl tests with a for loop
sysctl: Add 0012 to test the u8 range check
sysctl: move u8 register test to lib/test_sysctl.c
sparc: mv sparc sysctls into their own file under arch/sparc/kernel
stack_tracer: move sysctl registration to kernel/trace/trace_stack.c
tracing: Move trace sysctls into trace.c
signal: Move signal ctl tables into signal.c
panic: Move panic ctl tables into panic.c

Pull dma-mapping updates from Marek Szyprowski:
"New two step DMA mapping API, which is is a first step to a long path
to provide alternatives to scatterlist and to remove hacks, abuses and
design mistakes related to scatterlists.
This new approach optimizes some calls to DMA-IOMMU layer and cache
maintenance by batching them, reduces memory usage as it is no need to
store mapped DMA addresses to unmap them, and reduces some function
call overhead. It is a combination effort of many people, lead and
developed by Christoph Hellwig and Leon Romanovsky"
* tag 'dma-mapping-6.16-2025-05-26' of git://git.kernel.org/pub/scm/linux/kernel/git/mszyprowski/linux:
docs: core-api: document the IOVA-based API
dma-mapping: add a dma_need_unmap helper
dma-mapping: Implement link/unlink ranges API
iommu/dma: Factor out a iommu_dma_map_swiotlb helper
dma-mapping: Provide an interface to allow allocate IOVA
iommu: add kernel-doc for iommu_unmap_fast
iommu: generalize the batched sync after map interface
dma-mapping: move the PCI P2PDMA mapping helpers to pci-p2pdma.h
PCI/P2PDMA: Refactor the p2pdma mapping helpers

The function is small enough that it should be, and it's a (very) hot path
for io_uring. Doing this actually reduces my vmlinux text size for my
standard build/test box.
Before:
axboe@r7625 ~/g/linux (test)> size vmlinux
text data bss dec hex filename
19892174 5938310 2470432 28300916 1afd674 vmlinux
After:
axboe@r7625 ~/g/linux (test)> size vmlinux
text data bss dec hex filename
19891878 5938310 2470436 28300624 1afd550 vmlinux

The function __unmap_hugepage_range() has two kinds of users:
1) unmap_hugepage_range(), which passes in the head page of a folio.
Since unmap_hugepage_range() already takes folio and there are no other
uses of the folio struct in the function, it is natural for
__unmap_hugepage_range() to take folio also.
2) All other uses, which pass in NULL pointer.
In both cases, we can pass in folio. Refactor __unmap_hugepage_range() to
take folio.
