P4 to Git Change 1193228 by xcui@merged_opencl_jxcwin on 2015/09/22 18:52:47
SWDEV-59579 - resubmit the changelist 1193161. refactory the Coare-grained SVM and fine grain buffer SVM code path, so that if the device SVM running on supports fine grain system, then the SVM API operation will be on system memory, no need to go through GPU backend. In addition, added support for PX system with CZ on windows 10, which supports SVM fine grain system.
