perf evlist: Add perf_evlist__go_system_wide() helper stable inclusion from stable-v6.6.33 commit f33052802e3d05d1922af7a6e60d1f288087c80c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=f33052802e3d05d1922af7a6e60d1f288087c80c -------------------------------- commit f6ff1c760431be34e4daaa44f242be911becd998 upstream. For dummy events that keep tracking, we may need to modify its cpu_maps. For example, change the cpu_maps to record sideband events for all CPUS. Add perf_evlist__go_system_wide() helper to support this scenario.

libperf event: Ensure tracing data is multiple of 8 sized stable inclusion from stable-v6.6.113 commit afa0b258e07319db3686e897e98397110a896756 category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8637 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=afa0b258e07319db3686e897e98397110a896756 -------------------------------- [ Upstream commit b39c915a4f365cce6bdc0e538ed95d31823aea8f ] Perf's synthetic-events.c will ensure 8-byte alignment of tracing data, writing it after a perf_record_header_tracing_data event. Add padding to struct perf_record_header_tracing_data to make it 16-byte rather than 12-byte sized.
