Macros
#define	_Scheduler_Count   ( (size_t) 1 )
	This constant contains the count of configured schedulers.
#define	SCHEDULER_DEFAULT_SMP_OPERATIONS
	This define provides a set of default implementations for SMP-specific scheduler operations.
#define	SCHEDULER_DEFAULT_SET_AFFINITY_OPERATION
	This define provides the default implementation for the SMP-specific set affinity operation.
#define	PRIORITY_MAXIMUM   ( _Scheduler_Table[ 0 ].maximum_priority )
	This defines the lowest (least important) thread priority of the first scheduler instance.

Typedefs
typedef struct _Scheduler_Control	Scheduler_Control
typedef struct Scheduler_Context	Scheduler_Context
	Scheduler context.

Functions
Priority_Control	_Scheduler_default_Map_priority (const Scheduler_Control *scheduler, Priority_Control priority)
	Returns the scheduler internal thread priority mapped by SCHEDULER_PRIORITY_MAP().
Priority_Control	_Scheduler_default_Unmap_priority (const Scheduler_Control *scheduler, Priority_Control priority)
	Returns the user visible thread priority unmapped by SCHEDULER_PRIORITY_UNMAP().
void	_Scheduler_default_Schedule (const Scheduler_Control *scheduler, Thread_Control *the_thread)
	Does nothing.
void	_Scheduler_default_Node_initialize (const Scheduler_Control *scheduler, Scheduler_Node *node, Thread_Control *the_thread, Priority_Control priority)
	Performs the scheduler base node initialization.
void	_Scheduler_default_Node_destroy (const Scheduler_Control *scheduler, Scheduler_Node *node)
	Does nothing.
void	_Scheduler_default_Release_job (const Scheduler_Control *scheduler, Thread_Control *the_thread, Priority_Node *priority_node, uint64_t deadline, Thread_queue_Context *queue_context)
	Does nothing.
void	_Scheduler_default_Cancel_job (const Scheduler_Control *scheduler, Thread_Control *the_thread, Priority_Node *priority_node, Thread_queue_Context *queue_context)
	Does nothing.
void	_Scheduler_default_Start_idle (const Scheduler_Control *scheduler, Thread_Control *the_thread, struct Per_CPU_Control *cpu)
	Starts an idle thread.

Variables
const Scheduler_Control	_Scheduler_Table []
	This table contains the configured schedulers.
