/*

* trace_event macro definition

*

* trace_event() macro is used for logging events that occur at runtime.

* It comes in 2 main flavours, atomic and non-atomic. Depending of definitions

* above, it might also propagate log messages to mbox if desired.

*

* First argument is always class of event being logged, as defined in

* user/trace.h - TRACE_CLASS_* (deprecated - do not use).

* Second argument is string literal in printf format, followed by up to 4

* parameters (uint32_t), that are used to expand into string fromat when

* parsing log data.

*

* All compile-time accessible data (verbosity, class, source file name, line

* index and string literal) are linked into .static_log_entries section

* of binary and then extracted by smex, so they do not contribute to loadable

* image size. This way more elaborate log messages are possible and encouraged,

* for better debugging experience, without worrying about runtime performance.
