+Subject: perf: Treat attr.config as u64 in perf_swevent_init()
+
+Trinity discovered that we fail to check all 64 bits of
+attr.config passed by user space, resulting to out-of-bounds
+access of the perf_swevent_enabled array in
+sw_perf_event_destroy().
+
+Introduced in commit b0a873ebb ("perf: Register PMU
+implementations").
