      Pull remoteproc updates from Bjorn Andersson:
       "This introduces a new "detached" state for remote processors that are
        deemed to be running at the time Linux boots and the infrastructure
        for "attaching" to these. It then introduces the support for
        performing this operation for the STM32 platform.
      
        The coredump functionality is moved out from the core file and gains
        support for an optional mode where the recovery phase awaits the
        notification from devcoredump that the dump should be released. This
        allows userspace to grab the coredump in scenarios where vmalloc space
        is too low for creating a complete copy of the coredump before handing
        this to devcoredump.
      
        A new character device based interface is introduced to allow tying
        the stoppage of a remote processor to the termination of a user space
        process. This is useful in situations when such process provides
        crucial resources/operations for the firmware running on the remote
        processor.
      
        The Texas Instrument K3 driver gains support for the C66x and C71x
        DSPs.
      
        Qualcomm remoteprocs gains support for stashing relocation information
        in IMEM, to aid post mortem debugging and the crash notification
        mechanism is generalized to be reusable in cases where loosely coupled
        drivers needs to know about the status of a remote processor. One such
        example is the IPA hardware block, which is jointly owned with the
        modem and migrated to this improved interface.
      
        It also introduces a number of bug fixes and debug improvements for
        the Qualcomm modem remoteproc driver.
      
        And it cleans up the inconsistent interface for remoteproc drivers to
        implement power management"

      zonefs: update documentation to reflect zone size vs capacity · 4c96870e
      Johannes Thumshirn authored
      Update the zonefs documentation to reflect the difference between a zone's
      size and it's capacity.
      
      The maximum file size in zonefs is the zones capacity, for ZBC and ZAC
      based devices, which do not have a separate zone capacity, the zone
      capacity is equal to the zone size.

      zonefs: add zone-capacity support · e3c3155b
      Johannes Thumshirn authored
      In the zoned storage model, the sectors within a zone are typically all
      writeable. With the introduction of the Zoned Namespace (ZNS) Command
      Set in the NVM Express organization, the model was extended to have a
      specific writeable capacity.
      
      This zone capacity can be less than the overall zone size for a NVMe ZNS
      device or null_blk in zoned-mode. For other ZBC/ZAC devices the zone
      capacity is always equal to the zone size.
      
      Use the zone capacity field instead from blk_zone for determining the
      maximum inode size and inode blocks in zonefs.

      Linus Torvalds authored
      Pull perf tools updates from Arnaldo Carvalho de Melo:
       "New features:
      
         - Introduce controlling how 'perf stat' and 'perf record' works via a
           control file descriptor, allowing starting with events configured
           but disabled until commands are received via the control file
           descriptor. This allows, for instance for tools such as Intel VTune
           to make further use of perf as its Linux platform driver.
      
         - Improve 'perf record' to to register in a perf.data file header the
           clockid used to help later correlate things like syslog files and
           perf events recorded.
      
         - Add basic syscall and find_next_bit benchmarks to 'perf bench'.
      
         - Allow using computed metrics in calculating other metrics. For
           instance:
      
      	  {
      	    .metric_expr    = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit",
      	    .metric_name    = "DCache_L2_All_Hits",
      	  },
      	  {
      	    .metric_expr    = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss",
      	    .metric_name    = "DCache_L2_All_Miss",
      	  },
      	  {
      	     .metric_expr    = "dcache_l2_all_hits + dcache_l2_all_miss",
      	     .metric_name    = "DCache_L2_All",
      	  }
      
         - Add suport for 'd_ratio', '>' and '<' operators to the expression
           resolver used in calculating metrics in 'perf stat'.
      
        Support for new kernel features:
      
         - Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope
           with things like ftrace, trampolines, i.e. changes in the kernel
           text that gets in the way of properly decoding Intel PT hardware
           traces, for instance.
      
        Intel PT:
      
         - Add various knobs to reduce the volume of Intel PT traces by
           reducing the level of details such as decoding just some types of
           packets (e.g., FUP/TIP, PSB+), also filtering by time range.
      
         - Add new itrace options (log flags to the 'd' option, error flags to
           the 'e' one, etc), controlling how Intel PT is transformed into
           perf events, document some missing options (e.g., how to synthesize
           callchains).
      
        BPF:
      
         - Properly report BPF errors when parsing events.
      
         - Do not setup side-band events if LIBBPF is not linked, fixing a
           segfault.
      
        Libraries:
      
         - Improvements to the libtraceevent plugin mechanism.
      
         - Improve libtracevent support for KVM trace events SVM exit reasons.
      
         - Add a libtracevent plugins for decoding syscalls/sys_enter_futex
           and for tlb_flush.
      
         - Ensure sample_period is set libpfm4 events in 'perf test'.
      
         - Fixup libperf namespacing, to make sure what is in libperf has the
           perf_ namespace while what is now only in tools/perf/ doesn't use
           that prefix.
      
        Arch specific:
      
         - Improve the testing of vendor events and metrics in 'perf test'.
      
         - Allow no ARM CoreSight hardware tracer sink to be specified on
           command line.
      
         - Fix arm_spe_x recording when mixed with other perf events.

      Pull locking updates from Thomas Gleixner:
       "A set of locking fixes and updates:
      
         - Untangle the header spaghetti which causes build failures in
           various situations caused by the lockdep additions to seqcount to
           validate that the write side critical sections are non-preemptible.
      
         - The seqcount associated lock debug addons which were blocked by the
           above fallout.
      
           seqcount writers contrary to seqlock writers must be externally
           serialized, which usually happens via locking - except for strict
           per CPU seqcounts. As the lock is not part of the seqcount, lockdep
           cannot validate that the lock is held.
      
           This new debug mechanism adds the concept of associated locks.
           sequence count has now lock type variants and corresponding
           initializers which take a pointer to the associated lock used for
           writer serialization. If lockdep is enabled the pointer is stored
           and write_seqcount_begin() has a lockdep assertion to validate that
           the lock is held.
      
           Aside of the type and the initializer no other code changes are
           required at the seqcount usage sites. The rest of the seqcount API
           is unchanged and determines the type at compile time with the help
           of _Generic which is possible now that the minimal GCC version has
           been moved up.
      
           Adding this lockdep coverage unearthed a handful of seqcount bugs
           which have been addressed already independent of this.
      
           While generally useful this comes with a Trojan Horse twist: On RT
           kernels the write side critical section can become preemtible if
           the writers are serialized by an associated lock, which leads to
           the well known reader preempts writer livelock. RT prevents this by
           storing the associated lock pointer independent of lockdep in the
           seqcount and changing the reader side to block on the lock when a
           reader detects that a writer is in the write side critical section.

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've added two small interfaces: (a) GC_URGENT_LOW
        mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for
        security.
      
        The new GC mode allows Android to run some lower priority GCs in
        background, while new ioctl discards user information without race
        condition when the account is removed.
      
        In addition, some patches were merged to address latency-related
        issues. We've fixed some compression-related bug fixes as well as edge
        race conditions.
      
        Enhancements:
         - add GC_URGENT_LOW mode in gc_urgent
         - introduce F2FS_IOC_SEC_TRIM_FILE ioctl
         - bypass racy readahead to improve read latencies
         - shrink node_write lock coverage to avoid long latency
      
        Bug fixes:
         - fix missing compression flag control, i_size, and mount option
         - fix deadlock between quota writes and checkpoint
         - remove inode eviction path in synchronous path to avoid deadlock
         - fix to wait GCed compressed page writeback
         - fix a kernel panic in f2fs_is_compressed_page
         - check page dirty status before writeback
         - wait page writeback before update in node page write flow
         - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry

      Pull mtd updates from Miquel Raynal:
       "MTD core changes:
         - Spelling
         - http to https updates
      
        NAND core changes:
         - Drop useless 'depends on' in Kconfig
         - Add an extra level in the Kconfig hierarchy
         - Trivial spellings
         - Dynamic allocation of the interface configurations
         - Dropping the default ONFI timing mode
         - Various cleanup (types, structures, naming, comments)
         - Hide the chip->data_interface indirection
         - Add the generic rb-gpios property
         - Add the ->choose_interface_config() hook
         - Introduce nand_choose_best_sdr_timings()
         - Use default values for tPROG_max and tBERS_max
         - Avoid redefining tR_max and tCCS_min
         - Add a helper to find the closest ONFI mode
         - bcm63xx MTD parsers: simplify CFE detection
      
        Raw NAND controller drivers changes:
         - fsl-upm: Deprecation of specific DT properties
         - fsl_upm: Driver rework and cleanup in favor of ->exec_op()
         - Ingenic: Cleanup ARRAY_SIZE() vs sizeof() use
         - brcmnand: ECC error handling on EDU transfers
         - brcmnand: Don't default to EDU transfers
         - qcom: Set BAM mode only if not set already
         - qcom: Avoid write to unavailable register
         - gpio: Driver rework in favor of ->exec_op()
         - tango: ->exec_op() conversion
         - mtk: ->exec_op() conversion
      
        Raw NAND chip drivers changes:
         - toshiba: Implement ->choose_interface_config() for TH58NVG2S3HBAI4,
           TC58NVG0S3E, and TC58TEG5DCLTA00
         - hynix: Implement ->choose_interface_config() for H27UCG8T2ATR-BC
      
        SPI NOR core changes:
         - Disable Quad Mode in spi_nor_restore().
         - Don't abort BFPT parsing when QER reserved value is used.
         - Add support/update capabilities for few flashes.
         - Drop s70fl01gs flash: it does not support RDSR(05h) which is
           critical for erase/write.
         - Merge the SPIMEM DTR bits in spi-nor/next to avoid conflicts during
           the release cycle.
      
        SPI NOR controller drivers changes:
         - Move the cadence-quadspi driver to spi-mem. The series was taken
           through the SPI tree. Merge it also in spi-nor/next to avoid
           conflicts during the release cycle.
         - intel-spi:
            - Add new PCI IDs.
            - Ignore the Write Disable command, the controller doesn't support
              it.
            - Fix performance regression"

      kbuild: stop filtering out $(GCC_PLUGINS_CFLAGS) from cc-option base · 132305b3
      Masahiro Yamada authored
      Commit d26e9414 ("kbuild: no gcc-plugins during cc-option tests")
      was neeeded because scripts/Makefile.gcc-plugins was too early.
      
      This is unneeded by including scripts/Makefile.gcc-plugins last,
      and being careful to not add cc-option tests after it.
