Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
 "The main changes in this cycle were:

  Kernel side changes:

   - Kprobes and uprobes changes:
      - Make their trampolines read-only while they are used
      - Make UPROBES_EVENTS default-y which is the distro practice
      - Apply misc fixes and robustization to probe point insertion.

   - add support for AMD IOMMU events

   - extend hw events on Intel Goldmont CPUs

   - ... plus misc fixes and updates.

  Tooling side changes:

   - support s390 jump instructions in perf annotate (Christian
     Borntraeger)

   - vendor hardware events updates (Andi Kleen)

   - add argument support for SDT events in powerpc (Ravi Bangoria)

   - beautify the statx syscall arguments in 'perf trace' (Arnaldo
     Carvalho de Melo)

   - handle inline functions in callchains (Jin Yao)

   - enable sorting by srcline as key (Milian Wolff)

   - add 'brstackinsn' field in 'perf script' to reuse the x86
     instruction decoder used in the Intel PT code to study hot paths to
     samples (Andi Kleen)

   - add PERF_RECORD_NAMESPACES so that the kernel can record
     information required to associate samples to namespaces, helping in
     container problem characterization. (Hari Bathini)

   - allow sorting by symbol_size in 'perf report' and 'perf top'
     (Charles Baylis)

   - in perf stat, make system wide (-a) the default option if no target
     was specified and one of following conditions is met:
      - no workload specified (current behaviour)
      - a workload is specified but all requested events are system wide
        ones, like uncore ones. (Jiri Olsa)

   - ... plus lots of other updates, enhancements, cleanups and fixes"
