      Pull clk updates from Stephen Boyd:
       "This a large collection of clk driver updates and a handful of new SoC
        clk driver support.
      
        We have the usual Qualcomm clk drivers, along with clk drivers for the
        Sophgo and T-Head vendors, all to support some new SoCs.
      
        Nothing in particular stands out to me in the updates. There's the
        interconnect clk driver which exposes clks as interconnects, crossing
        subsystems. There's a bunch of janitorial things that are improving
        drivers in general like kmemdup_array() or fixing error paths. But
        overall the updates look normal to fix the description data which is
        usually the stuff that's wrong and/or untested.
      
        Core:
         - Skip gate basic type KUnit tests on s390 due to lack of MMIO
           emulation
      
        New Drivers:
         - AP sub-system clock controller in the T-Head TH1520
         - Sophgo Sophon sg2042 clk driver
         - Qualcomm SM7150 camera, display and video clk drivers
         - Qualcomm QCM2290 GPU clk driver
         - Qualcomm QCS8386/QCS8084 NSS clk driver
         - Qualcomm SM8650 camera and video drivers
      
        Updates:
         - Add reset support to Airoha EN7581 clk driver
         - Add MODULE_DESCRIPTIONs to various clk drivers
         - Introduce helper logic to expose clock controllers as simple
           interconnect providers
         - Use the interconnect helper above on Qualcomm ipq9574
         - Add CLK_SET_RATE_PARENT to the remaining USB pipe clocks on
           Qualcomm X1Elite
         - Improve error handling in Qualcomm kpss-xcc driver
         - Mark Qualcomm SC8280XP LPASS clock controller regmap_config const
         - Export more clocks for Rockchip rk3128 peripherals
         - Convert Rockchip clk drivers to use kmemdup_array()
         - Drop CLK_NR_CLKS from Rockchip rk3128 and rk3188 binding headers
         - Make qcom_cc_really_probe() take a struct device to allow reuse in
           non-platform-drivers
         - Introduce prepare-only branch clock ops in the qcom clk driver to
           support clocks on buses that take locks
         - Describe parent/child relationship for Qualcomm SC7280 camera GDSCs
         - Support Qualcomm Huayra 2290 alpha PLL
         - Adjust the highest SDCC clock frequency on Qualcomm IPQ6018 to
           match HS200 support
         - Add missing PCIe PIPE clocks on Qualcomm IPQ9574
         - Fix various configurations and properties in the Qualcomm SA8775P,
           X1E80100 and SM7280 drivers
         - Park Qualcomm SM8350 GPU RCGs on XO while disabled
         - Remove unused CONFIG_QCOM_RPMCC Kconfig symbol
         - exynos-clkout: Remove usage of of_device_id table as
           .of_match_table, because the driver is instantiated as MFD cell,
           not as standalone platform driver. Populated .of_match_table
           confused people few times to convert the code to
           device_get_match_data(), which broke the driver
         - Mark one Samsung UFS clock as critical, because having it off stops
           the system from shutdown
         - Use kmemdup_array() when applicable
         - Remove unused 'struct gates_data' from old sunxi driver library
         - Add GPADC clock and reset for Allwinner H616
         - Minor Amlogic S4 clock fixes
         - DT bindings Yaml conversion of the Amlogic AXG audio controller
         - Amlogic C3 clock controllers support
         - Amlogic clk flag added to skip init of already enabled PLLs and
           avoid relocking
         - Amlogic A1 DT bindings updates for system pll support
         - Add missing MODULE_DESCRIPTION where necessary
         - Remove obsolete clock DT binding header files
         - Add Battery Backup (VBATTB) and I2C clocks, resets, and power
           domains on Renesas RZ/G3S
         - Add audio clocks on Renesas R-Car V4M
         - Add video capture (ISPCS, CSI-2, VIN) clocks on Renesas R-Car V4M"

         The revised version has simpler logic.

         generated on fault capable HWPTs when a translation is not present.
      
         Routing them to userspace would allow a VMM to be able to virtualize

      dm-integrity: introduce the Inline mode · fb098768
      Mikulas Patocka authored
      This commit introduces a new 'I' mode for dm-integrity.
      
      The 'I' mode may be selected if the underlying device has non-power-of-2
      sector size. In this mode, dm-integrity will store integrity data
      directly in device's sectors and it will not use journal.
      
      This mode improves performance and reduces flash wear because there would
      be no journal writes.

      Pull bcachefs updates from Kent Overstreet:
      
       - Metadata version 1.8: Stripe sectors accounting, BCH_DATA_unstriped
      
         This splits out the accounting of dirty sectors and stripe sectors in
         alloc keys; this lets us see stripe buckets that still have unstriped
         data in them.
      
         This is needed for ensuring that erasure coding is working correctly,
         as well as completing stripe creation after a crash.
      
       - Metadata version 1.9: Disk accounting rewrite
      
         The previous disk accounting scheme relied heavily on percpu counters
         that were also sharded by outstanding journal buffer; it was fast but
         not extensible or scalable, and meant that all accounting counters
         were recorded in every journal entry.
      
         The new disk accounting scheme stores accounting as normal btree
         keys; updates are deltas until they are flushed by the btree write
         buffer.
      
         This means we have no practical limit on the number of counters, and
         a new tagged union format that's easy to extend.
      
         We now have counters for compression type/ratio, per-snapshot-id
         usage, per-btree-id usage, and pending rebalance work.
      
       - Self healing on read IO/checksum error
      
         Data is now automatically rewritten if we get a read error and then a
         successful retry
      
       - Mount API conversion (thanks to Thomas Bertschinger)
      
       - Better lockdep coverage
      
         Previously, btree node locks were tracked individually by lockdep,
         like any other lock. But we may take _many_ btree node locks
         simultaneously, we easily blow through the limit of 48 locks that
         lockdep can track, leading to lockdep turning itself off.
      
         Tracking each btree node lock individually isn't really necessary
         since we have our own cycle detector for deadlock avoidance and
         centralized tracking of btree node locks, so we now have a single
         lockdep_map in btree_trans for "any btree nodes are locked".
      
       - Some more small incremental work towards online check_allocations

      Kent Overstreet authored
      If a btree_trans is in use it's supposed to be passed to fsck_err so
      that it can be unlocked if we're waiting on userspace input; but the
      btree IO paths do call fsck errors where a btree_trans exists on the
      stack but it's not passed through.
      
      But it's ok, because it's unlocked while doing IO.

      Pull slab updates from Vlastimil Babka:
       "The most prominent change this time is the kmem_buckets based
        hardening of kmalloc() allocations from Kees Cook.
      
        We have also extended the kmalloc() alignment guarantees for
        non-power-of-two sizes in a way that benefits rust.
      
        The rest are various cleanups and non-critical fixups.
      
         - Dedicated bucket allocator (Kees Cook)
      
           This series [1] enhances the probabilistic defense against heap
           spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year.
      
           kmalloc() users that are known to be useful for exploits can get
           completely separate set of kmalloc caches that can't be shared with
           other users. The first converted users are alloc_msg() and
           memdup_user().
      
           The hardening is enabled by CONFIG_SLAB_BUCKETS.
      
         - Extended kmalloc() alignment guarantees (Vlastimil Babka)
      
           For years now we have guaranteed natural alignment for power-of-two
           allocations, but nothing was defined for other sizes (in practice,
           we have two such buckets, kmalloc-96 and kmalloc-192).
      
           To avoid unnecessary padding in the rust layer due to its alignment
           rules, extend the guarantee so that the alignment is at least the
           largest power-of-two divisor of the requested size.
      
           This fits what rust needs, is a superset of the existing
           power-of-two guarantee, and does not in practice change the layout
           (and thus does not add overhead due to padding) of the kmalloc-96
           and kmalloc-192 caches, unless slab debugging is enabled for them.
      
         - Cleanups and non-critical fixups (Chengming Zhou, Suren
           Baghdasaryan, Matthew Willcox, Alex Shi, and Vlastimil Babka)
      
           Various tweaks related to the new alloc profiling code, folio
           conversion, debugging and more leftovers after SLAB"

           python extension module can be automatic
      
         - Use pkg-config to check libtraceevent and libtracefs
      
        perf sched:
      
         - Add --task-name and --fuzzy-name options for `perf sched map`
      
           It focuses on selected tasks only by removing unrelated tasks in
           the output. It matches the task comm with the given string and the
           --fuzzy-name option allows the partial matching:
      
             $ sudo perf sched record -a sleep 1
      
             $ sudo perf sched map --task-name kworker --fuzzy-name

         - Fix -r/--repeat option of perf sched replay
      
           The documentation said -1 will work as infinity but it didn't
           accept the value. Update the code and document to use 0 instead
      
         - Fix perf sched timehist to account the delay time for preempted
           tasks
      
        Perf event filtering:
      
         - perf top gained filtering support on regular events using BPF like
           perf record. Previously it was able to use it for tracepoints only
      
         - The BPF filter now supports filtering by UID/GID. This should be
           preferred than -u <UID> option as it's racy to scan /proc to check
           tasks for the user and fails to open an event for the task if it's
           already gone
      
             $ sudo perf top -e cycles --filter "uid == $(id -u)"
      
        perf report:
      
         - Skip dummy events in the group output by default. The --skip-empty
           option controls display of empty events without samples. But perf
           report can force display all events in a group
      
           In this case, auto-added a dummy event (for a system-wide record)
           ends up in the output. Now it can skip those empty events even in
           the group display mode
      
           To preserve the old behavior, run this:
      
             $ perf report --group --no-skip-empty
      
        perf stat:
      
         - Choose the most disaggregate option when multiple aggregation
           options are given. It used to pick the last option in the command
           line but it can be confusing and not consistent. Now it'll choose
           the smallest unit
      
           For example, it'd aggregate the result per-core when the user gave
           both --per-socket and --per-core options at the same time
      
        Internals:
      
         - Fix `perf bench` when some CPUs are offline
      
         - Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map
           patterns only so that it can not be confused by other /tmp/perf-*
           files
      
         - Many improvements and fixes for `perf test`
      
        Others:
      
         - Support some new instructions for Intel-PT
      
         - Fix syscall ID mapping in perf trace
      
         - Document AMD IBS PMU usages
      
         - Change `perf lock info` to show map and thread info by default
      
        Vendor JSON events:
      
         - Update Intel events and metrics
      
         - Add i.MX9[35] DDR metrics"
