The reason is that we observe that a platform may use same Handler for different context. In order to support Unregister such handler, we have to input context information as well.

  Provides services to log the SMI handler registration.
 | 
						|
 | 
						|
  This API provides services for the SMM Child Dispatch Protocols provider,
 | 
						|
  to register SMI handler information to SmmCore.
 | 
						|
 | 
						|
  NOTE:
 | 
						|
  There is no need to update the consumers of SMST->SmiHandlerRegister() or
 | 
						|
  the consumers of SMM Child Dispatch Protocols.
 | 
						|
  The SmmCore (who produces SMST) should have ability to register such
 | 
						|
  information directly.
 | 
						|
  The SmmChildDispatcher (who produces SMM Child Dispatch Protocols) should
 | 
						|
  be responsible to call the services to register information to SMM Core.
