How about something like:

 u64 config = x86_pmu.event_map(_id);
 u64 event = (config & ARCH_PERFMON_EVENTSEL_EVENT) |
	     (config & AMD64_EVENTSEL_EVENT) >> 24;
 u64 umask = (config & ARCH_PERFMON_EVENTSEL_UMASK) >> 8;

 WARN_ON_ONCE(config & (ARCH_PERFMON_EVENTSEL_INV |
                        ARCH_PERFMON_EVENTSEL_CMASK));

 sprintf("event=0x%02llx,umask=0x%02llx\n", event, umask);
