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" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (235 commits) perf tools: Fix the code to strip command name tools arch x86: Sync cpufeatures.h tools arch: Sync arch/x86/lib/memcpy_64.S with the kernel tools: Update asm-generic/mman-common.h copy from the kernel perf tools: Use just forward declarations for struct thread where possible perf tools: Add the right header to obtain PERF_ALIGN() perf tools: Remove poll.h and wait.h from util.h perf tools: Remove string.h, unistd.h and sys/stat.h from util.h perf tools: Remove stale prototypes from builtin.h perf tools: Remove string.h from util.h perf tools: Remove sys/ioctl.h from util.h perf tools: Remove a few more needless includes from util.h perf tools: Include sys/param.h where needed perf callchain: Move callchain specific routines from util.[ch] perf tools: Add compress.h for the *_decompress_to_file() headers perf mem: Fix display of data source snoop indication perf debug: Move dump_stack() and sighandler_dump_stack() to debug.h perf kvm: Make function only used by 'perf kvm' static perf tools: Move timestamp routines from util.h to time-utils.h perf tools: Move units conversion/formatting routines to separate object ...
