Merge tag 'perf-urgent-for-mingo-5.3-20190708-2' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/urgent fixes from Arnaldo Carvalho de Melo: core: Arnaldo Carvalho de Melo: - Allow references to thread objects after__machine_exit(), fixing a bug with 'perf sched lat' where that happens, i.e. after perf_session__delete() we still have references to threads that were in a linked list whose head was freed in perf_session__delete(), causing a segfault, fix it. Jiri Olsa: - Do not rely on errno values for precise_ip fallback, fixing the default use case for 'perf record' on some AMD servers, when no events are specified and we try to use "cycles:P", i.e. with the maximum precision level. BPF: Song Liu: - Assign proper ff->ph in perf_event__synthesize_features(), fixing a bug when using pipe mode, i.e. 'perf record -o -'. tools headers: Arnaldo Carvalho de Melo: - Sync kvm headers with the kernel sources perf tests: Seeteena Thoufeek: - Fix record+probe_libc_inet_pton.sh for powerpc64, where without the debuginfo package for the 'ping' utility we can't resolve its symbols, so admit getting "[unknown]" for that backtrace line. perf python: Arnaldo Carvalho de Melo: - Remove -fstack-protector-strong if clang doesn't have it, fixing the build with clang on fedora:30, oracleline:7, centos:7. perf jvmti: Jiri Olsa: - Address gcc string overflow warning for strncpy() build: Arnaldo Carvalho de Melo: - Check if gettid() is available before providing helper, as recent versions of glibc started to provide gettid().
