Subject: [PATCH] P4 to Git Change 1138047 by gandryey@gera-w8 on 2015/04/07
 11:38:28

	ECR #304775 - Some code clean-up
	- Remove amd::Context reference from the event object. Runtime can use queue to get the context for the limited number of use cases
	- User/GL events will keep the context as a member
