Merge tag 'perf-tools-for-v5.15-2021-09-11' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull more perf tools updates from Arnaldo Carvalho de Melo: - Add missing fields and remove some duplicate fields when printing a perf_event_attr. - Fix hybrid config terms list corruption. - Update kernel header copies, some resulted in new kernel features being automagically added to 'perf trace' syscall/tracepoint argument id->string translators. - Add a file generated during the documentation build to .gitignore. - Add an option to build without libbfd, as some distros, like Debian consider its ABI unstable. - Add support to print a textual representation of IBS raw sample data in 'perf report'. - Fix bpf 'perf test' sample mismatch reporting - Fix passing arguments to stackcollapse report in a 'perf script' python script. - Allow build-id with trailing zeros. - Look for ImageBase in PE file to compute .text offset. * tag 'perf-tools-for-v5.15-2021-09-11' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (25 commits) tools headers UAPI: Update tools's copy of drm.h headers tools headers UAPI: Sync drm/i915_drm.h with the kernel sources tools headers UAPI: Sync linux/fs.h with the kernel sources tools headers UAPI: Sync linux/in.h copy with the kernel sources perf tools: Add an option to build without libbfd perf tools: Allow build-id with trailing zeros perf tools: Fix hybrid config terms list corruption perf tools: Factor out copy_config_terms() and free_config_terms() perf tools: Fix perf_event_attr__fprintf() missing/dupl. fields perf tools: Ignore Documentation dependency file perf bpf: Provide a weak btf__load_from_kernel_by_id() for older libbpf versions tools include UAPI: Update linux/mount.h copy perf beauty: Cover more flags in the move_mount syscall argument beautifier tools headers UAPI: Sync linux/prctl.h with the kernel sources tools include UAPI: Sync sound/asound.h copy with the kernel sources tools headers UAPI: Sync linux/kvm.h with the kernel sources tools headers UAPI: Sync x86's asm/kvm.h with the kernel sources perf report: Add support to print a textual representation of IBS raw sample data perf report: Add tools/arch/x86/include/asm/amd-ibs.h perf env: Add perf_env__cpuid, perf_env__{nr_}pmu_mappings ...
