From: Dapeng Mi A new bit PERF_CAPABILITIES[17] called "PEBS_TIMING_INFO" bit is added to indicated if PEBS supports to record timing information in a new "Retried Latency" field. Since KVM requires user can only set host consistent PEBS capabilities, otherwise the PERF_CAPABILITIES setting would fail, add pebs_timing_info into the "immutable_caps" to block host inconsistent PEBS configuration and cause errors. Opportunistically drop the anythread_deprecated bit. It isn't and likely never was a PERF_CAPABILITIES flag, the test's definition snuck in when the union was copy+pasted from the kernel's definition.
