Merge tag 'perf_urgent_for_v5.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Borislav Petkov: - Make sure PMU internal buffers are flushed for per-CPU events too and properly handle PID/TID for large PEBS. - Handle the case properly when there's no PMU and therefore return an empty list of perf MSRs for VMX to switch instead of reading random garbage from the stack. * tag 'perf_urgent_for_v5.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/perf: Use RET0 as default for guest_get_msrs to handle "no PMU" case perf/x86/intel: Set PERF_ATTACH_SCHED_CB for large PEBS and LBR perf/core: Flush PMU internal buffers for per-CPU events
