       "The main changes in this (fairly busy) cycle were:
         - There was a class of scheduler bugs related to forgetting to update
           the rq-clock timestamp which can cause weird and hard to debug
           problems, so there's a new debug facility for this: which uncovered
           a whole lot of bugs which convinced us that we want to keep the
           debug facility.

      Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 7f4eb0a6
      Linus Torvalds authored
      Pull perf updates from Ingo Molnar:
       "On the kernel side the main changes in this cycle were:
         - Add Intel Kaby Lake CPU support (Srinivas Pandruvada)
         - AMD uncore driver updates for fam17 (Janakarajan Natarajan)
         - Intel/PT updates and core events optimizations and cleanups
           (Alexander Shishkin)
         - cgroups events fixes (David Carrillo-Cisneros)
         - kprobes improvements (Masami Hiramatsu)
         - ... plus misc fixes and updates.
        On the tooling side the main changes were:
         - Support clang build in tools/{perf,lib/{bpf,traceevent,api}} with
           CC=clang, to, for instance, take advantage of better warnings
           (Arnaldo Carvalho de Melo):
         - Introduce the 'delta-abs' 'perf diff' compute method, that orders
           the histogram entries by the absolute value of the percentage delta
           for a function in two perf.data files, i.e. the functions that
           changed the most (increase or decrease in samples) comes first
           (Namhyung Kim)
         - Add support for parsing Intel uncore vendor event files and add
           uncore vendor events for the Intel server processors (Haswell,
           Broadwell, IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE
           (Andi Kleen)
         - Introduce 'perf ftrace' a perf front end to the kernel's ftrace
           function and function_graph tracer, defaulting to the
           "function_graph" tracer, more work will be done in reviving this
           effort, forward porting it from its initial patch submission
           (Namhyung Kim)
         - Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
           hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)
         - Account thread wait time (off CPU time) separately: sleep, iowait
           and preempt, based on the prev_state of the last event, show the
           breakdown when using "perf sched timehist --state" (Namhyumg Kim)
         - Add more triggers to switch the output file (perf.data.TIMESTAMP).
           Now, in addition to switching to a different output file when
           receiving a SIGUSR2, one can also specify file size and time based
                 perf record -a --switch-output=signal
           is equivalent to what we had before:
                 perf record -a --switch-output
           While we can also ask for the file to be "sliced" by size, taking
           into account that that will happen only when we get woken up by the
           kernel, i.e. one has to take into account the --mmap-pages (the
           size of the perf mmap ring buffer):
                 perf record -a --switch-output=2G
           will break the perf.data output into multiple files limited to 2GB
           of samples, right when generating the output.
           For time based samples, alert() will be used, so to have 1 minute
           limited perf.data output files:
                perf record -a --switch-output=1m
           (Jiri Olsa)
         - Improve 'perf trace' (Arnaldo Carvalho de Melo)
         - 'perf kallsyms' toy tool to look for extended symbol information on
           the running kernel and demonstrate the machine/thread/symbol APIs
           for use in other tools, such as 'perf probe' (Arnaldo Carvalho de
