Merge tag 'perf_urgent_for_v6.1_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Borislav Petkov: - Fix raw data handling when perf events are used in bpf - Rework how SIGTRAPs get delivered to events to address a bunch of problems with it. Add a selftest for that too * tag 'perf_urgent_for_v6.1_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: bpf: Fix sample_flags for bpf_perf_event_output selftests/perf_events: Add a SIGTRAP stress test with disables perf: Fix missing SIGTRAPs
