1aa4e2ed7c dt-bindings: clock: Replace bouncing emails
Replace permanently bouncing email addresses (550 5.1.1 Recipient address
rejected) of Adam Skladowski, Chanho Park, Anusha Rao and Sireesh
Kodali.  There are no new messages from them via other email addresses,
so drop them permanently.  Add Alim Akhtar to Samsung ExynosAutov9 SoC
clocks, because he looks at other Samsung clock hardware and drivers.

Pull RTC updates from Alexandre Belloni:
 "Most of the work and improvements are for features of the m41t93.

  The ds1307 also gets support for OSF (Oscillator Stop Flag) for
  new variants.

  The pcap driver is being removed as the Motorola EZX support was
  removed a while ago.

  Subsystem:
   - add rtc_read_next_alarm() to read next expiring timer

  Drivers:
   - ds1307: handle OSF for ds1337/ds1339/ds3231, add clock provider for
     ds1307, fix wday for rx8130
   - m41t93: DT support, alarm, clock provider, watchdog support

cd1c188db1 vlan: defer real device state propagation to netdev_work
vlan_device_event() generates nested UP/DOWN, MTU and feature
change events. It executes an event for the VLAN device directly
from the notifier - while the locks of the lower device are held.

This causes deadlocks, for example:

  bond    (3) bond_update_speed_duplex(vlan)
    |           ^                v
  vlan    (2) UP(vlan)    (4) vlan_ethtool_get_link_ksettings()
    |           ^                v
  dummy   (1) UP(dummy)   (5) __ethtool_get_link_ksettings()

The dummy device is ops locked, vlan creates a nested event (2),
then bond wants to ask vlan for link state (3). bond uses the
"I'm already holding the instance lock" flavor of API. But in
this case the lock held refers to vlan itself. We hit vlan's
link settings trampoline (4) and call __ethtool_get_link_ksettings()
which tries to lock dummy. Deadlock. There's no clean way for us
to tell the vlan_ethtool_get_link_ksettings() that the caller
is already in lower device's critical section.

Defer the propagation to the per-netdev work facility instead:
the notifier only schedules netdev_work_sched(vlandev, VLAN_WORK_*),
and ndo_work (vlan_dev_work) applies the change later. Hopefully
nobody expects the VLAN state changes to be instantaneous.

If someone does expect the changes to be instantaneous we will
have to do the same thing Stan did for rx_mode and "strategically"
place sync calls, to make sure such delayed works are executed
after we drop the ops lock but before we drop rtnl_lock.

Stan suggests that if we need that down the line we may
consider reshaping the mechanism into "async notifications".
AFAICT only vlan does this sort of netdev open chaining,
so as a first try I think that sticking the complexity into
the vlan code makes sense.

One corner case is that we need to cancel the event if user
explicitly changes the state before work could run. Consider
the following operations with vlan0 on top of dummy0:

  ip link set dev dummy0 up    # queues work to up vlan0
  ip link set dev vlan0 down   # user explicitly downs the vlan
  ndo_work                     # acts on the stale event

Emails to the maintainer of Qualcomm PPE Ethernet driver (Luo Jie
<quic_luoj@quicinc.com>) bounce permanently (full mailbox), because the
"quicinc.com" addresses were deprecated for public work.  All Qualcomm
contributors are aware of that and were asked to fix their addresses.

Driver is not supported - in terms of how netdev understands supported
commitment - if maintainer does not care to receive the patches for its
code, so demote it to "maintained" to reflect true status.

Fix all occurences of Luo Jie email address to preferred and working
domain.

7b5944d6ed LoongArch: Add THREAD_INFO_IN_TASK implementation
Like other architectures such as x86, arm64, riscv, powerpc and s390,
select THREAD_INFO_IN_TASK for LoongArch to move thread_info off the
stack into task_struct. This follows modern kernel standards and also
makes the system more secure.

With this patch, thread_info is included in task_struct at an offset
of 0 instead of being placed at the bottom of the kernel stack. Thus,
the $tp register points to both thread_info and task_struct.

To support this, introduce a per-CPU variable cpu_tasks to store the
pointer to the current task_struct. This decouples the recovery	of the
$tp register from the stack pointer during exception entry.

Then initialize cpu_tasks for the primary and secondary CPUs during
arch-specific setup and SMP boot paths. To eliminate the dangerous
windows during the early initialization where the cpu_tasks remains
uninitialized, set_current() is invoked as early as possible in both
setup_arch() and start_secondary(). This ensures the $tp recovery
barrier is armed in case any early boot exceptions or kernel panics
occur.

Modify SAVE_SOME and handle_syscall to restore the $tp register from
cpu_tasks, and also use the la_abs absolute addressing for cpu_tasks
access in assembly to bypass the relocation limits within exception
handling sections. By advancing the preservation of u0 in SAVE_SOME,
we reuse the PERCPU_BASE_KS value in u0 for the cpu_tasks calculation,
effectively eliminating a duplicate csrrd instruction execution on SMP
platforms.

Update <asm/switch_to.h> and <kernel/switch.S> to fully support the
CONFIG_THREAD_INFO_IN_TASK feature.

Remove the obsolete next_ti argument from __switch_to(), which shifts
the remaining arguments ahead in the calling convention (sched_ra from
a3 to a2, and sched_cfa from a4 to a3). Under the new configuration,
__switch_to() now directly derives the thread pointer ($tp) from the
next task_struct pointer in a1.

To preserve the optimal and clean "move tp, a1" path for 64-bit kernels,
the thread pointer ($tp) is assigned directly from a1 in the core path.
For 32-bit kernels, where a1 carries a 2000-byte structural pointer bias
at entry, an explicit adjustment "PTR_ADDI tp, tp, -TASK_STRUCT_OFFSET"
is introduced at the function exit.

In the context of __switch_to(), local interrupts are disabled, and the
kernel is in a critical switching phase where handling any synchronous
exception is practically impossible and prohibited.

If any synchronous exception or watchpoint does trigger in this narrow
window, it constitutes a fatal double fault and the kernel is expected
to die/panic immediately anyway. Therefore, the temporary biased value
in $tp is safe and acceptable here.

Additionally, evaluate the stack lookup as a single load instruction
"LONG_LPTR t0, a1, (TASK_STACK - TASK_STRUCT_OFFSET)", this perfectly
satisfies both 32-bit and 64-bit kernels. Using the "next" pointer in
a1 as the base register, rather than $tp, effectively unchains the data
dependency (RAW hazard) from the preceding move instruction, maximizing
the instruction-level parallelism and superscalar execution efficiency
while naturally adapting the structural shift.

With CONFIG_THREAD_INFO_IN_TASK enabled, the kernel stack life cycle is
decoupled from task_struct and can be freed concurrently.

Currently, show_stacktrace() reads raw stack data via __get_addr() and
subsequently calls show_backtrace() to unwind the frame, without holding
any reference to the target task's stack. If show_stacktrace() is called
on a concurrently exiting task, it could attempt to read from a freed or
reallocated kernel stack. This introduces a severe use-after-free (UAF)
read risk or kernel panics.

Wrap the entire stack inspection process inside show_stacktrace() with
a try_get_task_stack() and put_task_stack() pair. This ensures the task
stack remains pinned safely during both the raw stack data dump loop and
the subsequent stack unwinding phase.

Also, ensure that the task pointer is initialized to "current" early if
it is NULL, so that try_get_task_stack() always operates on a valid task
reference.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
     around a WiFi device defect; use a quirk or boot-time
     "pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)

   - Always lift 2.5GT/s restriction in PCIe failed link retraining to
     avoid clamping a link to 2.5GT/s after hot-plug changes the device
     (Maciej W. Rozycki)

   - Request bus reassignment when not probe-only to fix an enumeration
     regression on Marvell CN106XX and possibly other DT-based systems
     (Ratheesh Kannoth)

   - Fix procfs race between pci_proc_init() and pci_bus_add_device()
     that resulted in 'proc_dir_entry ... already registered' warnings
     and pointer corruption (Krzysztof Wilczyński)

   - Fix sysfs race that causes 'duplicate filename' warnings and boot
     panics by converting PCI resource files to static attributes
     (Krzysztof Wilczyński)

   - Expose sysfs 'resourceN_resize' attributes only on platforms with
     PCI mmap (Krzysztof Wilczyński)

   - Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
     attributes (Krzysztof Wilczyński)

   - Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
     mmap path to match the generic path (Krzysztof Wilczyński)

   - Use kstrtobool() to parse the 'rom' attribute input to avoid the
     unexpected behavior of enabling the ROM when writing '0' with no
     trailing newline (Krzysztof Wilczyński)

  Resource management:

   - Improve resource claim logging for debuggability (Ilpo Järvinen)

   - Clean up several uses of const parameters (Ilpo Järvinen)

   - Check option ROM header signatures and lengths before accessing to
     avoid page faults and alignment faults (Guixin Liu)

  ASPM:

   - Don't reconfigure ASPM when entering low-power D-state; only do it
     when returning back to D0 (Carlos Bilbao)

  Power management:

   - During suspend, set power state to 'unknown' for all devices, not
     just those with drivers (Lukas Wunner)

   - Skip restoring Resizable BARs and VF Resizable BARs if device
     doesn't respond to config reads, to avoid invalid array accesses
     (Marco Nenciarini)

   - Add pci_suspend_retains_context() so drivers can tell whether
     devices retain internal state across suspend/resume, since some
     platforms reset devices on suspend; use this in nvme to avoid
     issues on Qcom RCs (Manivannan Sadhasivam)

  Power control:

   - Only to power on/off devices that actually support power control to
     avoid poking at incompatible devices mentioned in DT (Manivannan
     Sadhasivam)

  Virtualization and resets:

   - Log device readiness timeouts as errors, not warnings, because the
     device is likely unusable in this case (Bjorn Helgaas)

   - Wait for device readiness after soft reset (D3hot ->
     D0uninitialized transition), when the device may respond with
     Request Retry Status (RRS) if it needs more time to initialize
     (Bjorn Helgaas)

   - Drop unnecessary retries when restoring BARs because resets should
     now already include all required delays (Lukas Wunner)

   - Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
     terminates uncleanly (Jose Ignacio Tornos Martinez)

   - Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
     which seem not to support it correctly (Jose Ignacio Tornos
     Martinez)

  Peer-to-peer DMA:

     test (Carlos Bilbao)

   - Unwind MSI/MSI-X vectors if NTB initialization fails part-way
     through (Koichiro Den)

   - Cache sleepable pci_irq_vector() value at ISR setup to avoid
     calling it from hardirq context (Koichiro Den)

   - Call sleepable pci_epc_raise_irq() from a work item instead of
     atomic context, e.g., when setting bits in NTB peer doorbells in
     the ntb_peer_db_set() path (Koichiro Den)

   - Report 0-based vNTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Prevent configfs writes to vNTB db_count and other values that are
     already in use after EPC attach (Koichiro Den)

   - Account for vNTB db_valid reserved slots (link event 0 and
     historically skipped slot 1) so they don't appear as valid
     doorbells (Koichiro Den)

   - Implement vNTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors and avoid thundering herds (Koichiro Den)

   - Report 0-based NTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Fix doorbell bitmask and IRQ vector handling to clear only
     specified bits, use the correct vector for non-contiguous Linux IRQ
     numbers, and validate incoming vectors (Koichiro Den)

   - Implement NTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors (Koichiro Den)

  Native PCIe controller infrastructure:

     after > 5GT/s Link training completes and use it for cadence HPA,
     j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)

   - Protect root bus removal with rescan lock in altera, brcmstb,

     use-after-free or crashes when racing with sysfs rescan or hotplug
     (Hans Zhang)

   - Add pci_host_common_parse_ports() for use by any native driver to
     parse Root Port properties (per-Link features like width, speed,
     PHY, power and reset control, etc should be described in Root Port
     stanzas, not the host bridge; currently only reset GPIOs
     implemented) (Sherry Sun)

   - Add .get_ltssm() callback to get the LTSSM status without DBI,
     since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya

     avoid power leakage (Krishna Chaitanya Chundru)

   - Add qcom D3cold support to tear down interconnect bandwidth and OPP
     votes (Krishna Chaitanya Chundru)

Pull f2fs updates from Jaegeuk Kim:
 "The changes primarily focus on filesystem error reporting, reducing
  memory footprint by reverting in-memory data structures used for
  runtime validation, honoring FDP hints, and adding trace and debug
  logs. In addition, there are critical bug fixes resolving
  out-of-bounds read vulnerabilities in inline directory and ACL
  handling, potential deadlocks in balance_fs, use-after-free issues in
  atomic writes, and false data/node type assignments in large sections.

  Enhancements:
   - Revert  in-memory sit version and block bitmaps
   - support to report fserror
   - add trace_f2fs_fault_report
   - add iostat latency tracking for direct IO
   - add logs in f2fs_disable_checkpoint()
   - honor per-I/O write streams for direct writes
   - map data writes to FDP streams
   - skip inode folio lookup for cached overwrite
   - skip direct I/O iostat context when disabled
   - revert "check in-memory block bitmap"
   - revert "check in-memory sit version bitmap"

  Fixes:
   - optimize representative type determination in GC
   - fix incorrect FI_NO_EXTENT handling in __destroy_extent_node()
   - fix potential deadlock in f2fs_balance_fs()
   - fix potential deadlock in gc_merge path of f2fs_balance_fs()
   - atomic: fix UAF issue on f2fs_inode_info.atomic_inode
   - fix missing read bio submission on large folio error
   - pass correct iostat type for single node writes
   - fix to do sanity check on f2fs_get_node_folio_ra()
   - validate orphan inode entry count
   - keep atomic write retry from zeroing original data
   - read COW data with the original inode during atomic write
   - validate inline dentry name lengths before conversion
   - validate dentry name length before lookup compares it
   - reject setattr size changes on large folio files
   - revert "remove non-uptodate folio from the page cache in move_data_block"
   - validate ACL entry sizes in f2fs_acl_from_disk()
   - bound i_inline_xattr_size for non-inline-xattr inodes
   - fix listxattr handling of corrupted xattr entries

The UIO howto still documents an mmap callback in struct uio_info.
That field was replaced by mmap_prepare, which takes a struct
vm_area_desc.

A UIO driver following the current howto no longer builds because
struct uio_info has no mmap member. Update the documented callback
signature and matching text to match the current API.

Pull perf tools updates from Arnaldo Carvalho de Melo:

 - Introduce 'perf inject --aslr' to remap ASLR-randomized addresses in
   perf.data files, enabling reproducible analysis across runs with
   different address space layouts

 - Refactor evsel out of sample processing paths: store evsel in struct
   perf_sample and remove the redundant evsel parameter from tool APIs,
   tracepoint handlers, hist entry iterators, and db-export, simplifying
   the entire tool callback chain

 - Switch architecture detection from string-based perf_env__arch()
   comparisons to the numeric ELF e_machine field across the codebase
   (capstone, print_insn, c2c, lock-contention, sort, sample-raw,
   machine, header), making cross-analysis more robust

 - Overhaul ARM CoreSight ETM tests: add deterministic and named_threads
   workloads, speed up basic and disassembly tests, add process
   attribution and concurrent threads tests, remove unused workloads and
   duplicate tests, queue context packets for the frontend decoder

 - Add ARM SPE IMPDEF event decoding for Arm Neoverse N1, store MIDR in
   arm_spe_pkt for per-CPU event mapping, handle missing CPU IDs
   gracefully

 - Refactor libunwind support: remove the libunwind-local backend, make
   register reading cross-platform, add RISC-V libunwind support, allow
   dynamic selection between libdw and libunwind unwinding at runtime

 - Extensive hardening of perf.data parsing against crafted files: add
   bounds checks and byte-swap validation for session records, feature
   sections, header attributes, BPF metadata, auxtrace errors,
   compressed events, CPU maps, build ID notes, and ELF program headers.
   Add minimum event size validation and file offset diagnostics

 - Fix libdw API contract violations across dwarf-aux, libdw,
   probe-finder, annotate-data, and debuginfo subsystems. Fix callchain
   parent update in ORDER_CALLER mode, support DWARF line 0 in inline
   lists, handle multiple address spaces in callchains

 - Fix numerous 'perf sched' bugs: thread reference leaks, memory leaks,
   heap overflows with cross-machine recordings, NULL dereferences,
   replace BUG_ON assertions with graceful error handling, bounds-check
   CPU indices, fix SIGCHLD vs pause() races in sched stats

 - Overhaul the build system: move BPF skeleton generation out of
   Makefile.perf into bpf_skel.mak, decouple pmu-events from the prepare
   target, make beauty generated C code standalone .o files, compile BPF
   skeletons with -mcpu=v3, fix continuous rebuilds, various cleanups

 - Add 'perf test' JUnit XML reporting with -j/--junit option, split
   monolithic test suites into sub-tests, add summary reporting,
   refactor parallel poll loop, fix test failures on musl-based systems

 - Fix 'perf c2c' memory leaks in hist entry and format list handling,
   use-after-free in error paths, bounds-check CPU and node IDs

 - Fix 'perf bpf' metadata leaks on duplicate insert and alloc failure,
   bounds-check array offsets, validate event sizes and func_info
   fields, add NULL checks

 - Fix hwmon PMU: off-by-one null termination on sysfs reads, strlcpy
   buffer overflow in parse_hwmon_filename(), fd 0 check, empty label
   reads, scnprintf usage

 - Fix symbols subsystem: bounds-check ELF and sysfs build ID note
   iteration, validate p_filesz, fix 32-bit ELF bswap error, fix signed
   overflow in size checks, bounds-check .gnu_debuglink section

 - Fix tools lib api: null termination in filename__read_int/ull(),
   uninitialized stack data in filename__write_int(), snprintf
   truncation in mount_overload()

 - Replace libbabeltrace with babeltrace2-ctf-writer for CTF conversion
   in 'perf data'

 - Add RISC-V SDT argument parsing for static tracepoints

 - Add 'perf trace --show-cpu' option to display CPU id

 - Add 'perf bench sched pipe --write-size' option

 - Add a perf-specific .clang-format that overrides some kernel style
   behaviors

 - Update Intel vendor events for Alder Lake, Arrow Lake, Clearwater
   Forest, Emerald Rapids, Granite Rapids, Grand Ridge, Lunar Lake,
   Meteor Lake, Panther Lake, Sapphire Rapids, Sierra Forest

 - Add IOMMU metrics for AMD and Intel

 - Fix AMD event: switch l2_itlb_misses to
   bp_l1_tlb_miss_l2_tlb_miss.all

 - Add AMD IBS improvements: decode Streaming-store and Remote-Socket
   flags, suppress bogus fields on Zen4+, skip privilege test on Zen6+

 - Fix 'perf lock contention' SIGCHLD vs pause() race, allow 'mmap_lock'
   in -L filter, enable end-timestamp for cgroup aggregation, fix
   non-atomic data updates

   bounds-check CPU index in topology callbacks, add aggr_nr metric
   parser support for uncore scaling

 - Fix 'perf timechart' memory leaks, CPU bounds checking,
   use-after-free on corrupted callchains

 - Fix 'perf inject' itrace branch stack synthesis, fix synthesized
   sample size with branch stacks

 - Fix DSO heap overflow on decompressed paths, uninitialized pathname
   on fallback, set proper error codes

 - Fix various snprintf/scnprintf usages to prevent buffer overflows and
   truncation across the codebase

 - Fix off-by-one stack buffer overflow in kallsyms__parse()

 - Fix 'perf kwork' memory management, address sanitizer issues, bounds
   check work->cpu

 - Fix 'perf tpebs' concurrent stop races and PID reuse hazards

 - Add O_CLOEXEC to open() calls and use mkostemp() for temporary files
   to prevent file descriptor leaks to child processes

 - Fix s390 Python extension TEXTREL by compiling as PIC

 - Fix build with ASAN for jitdump

 - Fix build failure due to btf_vlen() return type change

ad4c2a8fd8 dt-bindings: PCI: qcom,pcie-sm8550: Add Eliza compatible
PCIe controller present in Eliza SoC is backwards compatible with the
controller present in SM8550 SoC. Hence, add the compatible with SM8550
fallback.

Eliza requires 6 reg entries, 8 clocks and 9 interrupts, so add the
corresponding allOf constraints.

e8433f6321 dt-bindings: PCI: renesas,r9a08g045-pcie: Add RZ/V2N support
Document the Renesas RZ/V2N PCIe host controller, which is compatible with
the RZ/G3E PCIe IP and therefore uses it as a fallback compatible. The
only difference is that it uses device ID 0x003B.

Make the binding title generic to avoid extending the title for each new
SoC, and update the description to list the supported SoCs and their
capabilities.
