So I'm # sending this nevertheless because rebasing and distangling fixes and # updates would be a mess and risky as well. As of tomorrow, a strict # fixes separation is happening again. Sorry for the slip-up. # # Kernel: # # - Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different # consumers of the mmap event get what they requested. # # Tools: # # - A larger set of updates to perf record/report/scripts vs. time # stamp handling # # - More Python3 fixups # # - A pile of memory leak plumbing # # - perf BPF improvements and fixes # # - Finalize the perf.data directory storage" # # [ Note: the kernel part is strictly a fix, the updates are purely to # tooling - Linus ] # # * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (75 commits) # perf bpf: Show more BPF program info in print_bpf_prog_info() # perf bpf: Extract logic to create program names from perf_event__synthesize_one_bpf_prog() # perf tools: Save bpf_prog_info and BTF of new BPF programs # perf evlist: Introduce side band thread # perf annotate: Enable annotation of BPF programs # perf build: Check what binutils's 'disassembler()' signature to use # perf bpf: Process PERF_BPF_EVENT_PROG_LOAD for annotation # perf symbols: Introduce DSO_BINARY_TYPE__BPF_PROG_INFO # perf feature detection: Add -lopcodes to feature-libbfd # perf top: Add option --no-bpf-event # perf bpf: Save BTF information as headers to perf.data # perf bpf: Save BTF in a rbtree in perf_env # perf bpf: Save bpf_prog_info information as headers to perf.data # perf bpf: Save bpf_prog_info in a rbtree in perf_env # perf bpf: Make synthesize_bpf_events() receive perf_session pointer instead of perf_tool # perf bpf: Synthesize bpf events with bpf_program__get_prog_info_linear() # bpftool: use bpf_program__get_prog_info_linear() in prog.c:do_dump() # tools lib bpf: Introduce bpf_program__get_prog_info_linear() # perf record: Replace option --bpf-event with --no-bpf-event # perf tests: Fix a memory leak in test__perf_evsel__tp_sched_test() # ... # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 49ef015632ab3fcc19b2cb37b199d6d7ebcfa5f8 # < make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # yes \n \| make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/kernel/skas/uaccess.c: In function 'do_op_one_page': /kisskb/src/arch/um/kernel/skas/uaccess.c:62:10: warning: unused variable 'buf' [-Wunused-variable] jmp_buf buf;
