       "Kernel side changes:
      
         - Add AMD Fam17h RAPL support
      
         - Introduce CAP_PERFMON to kernel and user space
      
         - Add Zhaoxin CPU support
      
         - Misc fixes and cleanups
      
        Tooling changes:
      
         - perf record:
      
           Introduce '--switch-output-event' to use arbitrary events to be
           setup and read from a side band thread and, when they take place a
           signal be sent to the main 'perf record' thread, reusing the core
           for '--switch-output' to take perf.data snapshots from the ring
           buffer used for '--overwrite', e.g.:
      
      	# perf record --overwrite -e sched:* \
      		      --switch-output-event syscalls:*connect* \
      		      workload
      
           will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
           connect syscalls.
      
           Add '--num-synthesize-threads' option to control degree of
           parallelism of the synthesize_mmap() code which is scanning
           /proc/PID/task/PID/maps and can be time consuming. This mimics
           pre-existing behaviour in 'perf top'.
      
         - perf bench:
      
           Add a multi-threaded synthesize benchmark and kallsyms parsing
           benchmark.
      
         - Intel PT support:
      
           Stitch LBR records from multiple samples to get deeper backtraces,
           there are caveats, see the csets for details.
      
           Allow using Intel PT to synthesize callchains for regular events.
      
           Add support for synthesizing branch stacks for regular events
           (cycles, instructions, etc) from Intel PT data.
      
        Misc changes:
      
         - Updated perf vendor events for power9 and Coresight.
      
         - Add flamegraph.py script via 'perf flamegraph'
      
         - Misc other changes, fixes and cleanups - see the Git log for details
      
        Also, since over the last couple of years perf tooling has matured and
        decoupled from the kernel perf changes to a large degree, going
        forward Arnaldo is going to send perf tooling changes via direct pull
        requests"

      mtd: Support kmsg dumper based on pstore/blk · 78c08247
      WeiXiong Liao authored
      This introduces mtdpstore, which is similar to mtdoops but more
      powerful. It uses pstore/blk, and aims to store panic and oops logs to
      a flash partition, where pstore can later read back and present as files
      in the mounted pstore filesystem.
      
      To make mtdpstore work, the "blkdev" of pstore/blk should be set
      as MTD device name or MTD device number. For more details, see
      Documentation/admin-guide/pstore-blk.rst
      
      This solves a number of issues:
      - Work duplication: both of pstore and mtdoops do the same job storing
        panic/oops log. They have very similar logic, registering to kmsg
        dumper and storing logs to several chunks one by one.
      - Layer violations: drivers should provides methods instead of polices.
        MTD should provide read/write/erase operations, and allow a higher
        level drivers to provide the chunk management, kmsg dump
        configuration, etc.
      - Missing features: pstore provides many additional features, including
        presenting the logs as files, logging dump time and count, and
        supporting other frontends like pmsg, console, etc.

      pstore/blk: Introduce "best_effort" mode · f8feafea
      Kees Cook authored
      In order to use arbitrary block devices as a pstore backend, provide a
      new module param named "best_effort", which will allow using any block
      device, even if it has not provided a panic_write callback.
