Declaring the defines needed for suppressing warning inside '#ifdef CONFIG_DEBUG_BUGVERBOSE' results in a kerneldoc warning. .../bug.h:29: warning: expecting prototype for _EMIT_BUG_ENTRY(). Prototype was for HAVE_BUG_FUNCTION() instead Move the defines above the kerneldoc entry for _EMIT_BUG_ENTRY to make kerneldoc happy.
