Daniel P. Berrange	9397740244	trace: remove global 'uint16 dstate[]' array Instead of having a global dstate array, declare a single 'uint16 TRACE_${EVENT_NAME}_DSTATE' variable for each trace event. Record a pointer to this variable in the TraceEvent struct too. By turning trace_event_get_state_dynamic_by_id into a macro, this still hits the fast path, and cache affinity is ensured by declaring all the uint16 vars adjacent to each other.

Lluís Vilanova	2bfe11c8fa	trace: Properly initialize dynamic event states in hot-plugged vCPUs Every time a vCPU is hot-plugged, it will "inherit" its tracing state from the global state array. That is, if any existing vCPU has an event enabled, new vCPUs will have too.

Lluís Vilanova	8eb1b9db55	trace: Avoid implicit bool->integer conversions An explicit if/else is clearer than arithmetic assuming #true is 1, while the compiler should be able to generate just as optimal code.

Lluís Vilanova	a4d50b1d2a	trace: Remove 'trace_events_dstate_init' Removes the event state array used for early initialization. Since only events with the "vcpu" property need a late initialization fixup, threats their initialization specially. Assumes that the user won't touch the state of "vcpu" events between early and late initialization (e.g., through QMP).

Lluís Vilanova	4815185902	trace: Add per-vCPU tracing states for events with the 'vcpu' property Each vCPU gets a 'trace_dstate' bitmap to control the per-vCPU dynamic tracing state of events with the 'vcpu' property.
