Merge tag 'perf_urgent_for_v5.18_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Borislav Petkov:
- A couple of fixes to cgroup-related handling of perf events
- A couple of fixes to event encoding on Sapphire Rapids
- Pass event caps of inherited events so that perf doesn't fail wrongly
at fork()
- Add support for a new Raptor Lake CPU
