mainline inclusion from mainline-v6.8-rc1 commit eb00697b91646de22d6d9b4e6a5fadf4495fdf69 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9Q2KV CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
The legacy events cpu-cycles and instructions have sysfs event equivalents on x86 (see /sys/devices/cpu_core/events).
As sysfs/JSON events are now higher in priority than legacy events this causes the hybrid test expectations not to be met.
To fix this switch to legacy events that don't have sysfs versions, namely cpu-cycles becomes cycles and instructions becomes branches.
