2017-05-19	s390x/css: ccw translation infrastructure	Xiao Feng Ren	1	-0/+12
	Implement a basic infrastructure of handling channel I/O instruction interception for passed through subchannels: 1. Branch the code path of instruction interception handling by SubChannel type. 2. For a passed-through subchannel, issue the ORB to kernel to do ccw translation and perform an I/O operation. 3. Assign different condition code based on the I/O result, or trigger a program check.

2017-05-19	s390x/css: device support for s390-ccw passthrough	Dong Jia Shi	1	-0/+141
	In order to support subchannels pass-through, we introduce a s390 subchannel device called "s390-ccw" to hold the real subchannel info. The s390-ccw devices inherit from the abstract CcwDevice which connect to the existing virtual-css-bus.
