amd64: drop unused amd64_fam1ah_zen5_retired_serializing_ops table
The amd64_fam1ah_zen5_retired_serializing_ops[] umask table is defined
in lib/events/amd64_events_fam1ah_zen5.h but is not referenced by any
event entry in amd64_fam1ah_zen5_pe[]. It is dead code that was added
together with the initial Zen5 support and has never been wired up.
No functional change.

Note: The PAPI team does not have access to a machine with an AMD Zen 6. However, testing was done on an AMD Zen 5 (AMD Ryzen 9 9950X 16-Core Processor).
From testing, the PAPI utilities: papi_component_avail, papi_avail, papi_native_avail, and papi_command_line ran successfully. Furthermore, the perf_event
component tests nmi_watchdog, perf_event_system_wide, and perf_event_user_kernel all ran successfully (the tests broken_events and perf_event_offcore_response do
not have events defined for the AMD Zen 5 architecture).

Since I do not have a system with the Zen6 CPU architecture, I tested these changes on a system containing an AMD EPYC 9755 CPU (Zen5 architecture). The PAPI utilities function properly. |
