2016-09-06	s390x/cpumodel: introduce CPU feature group definitions	David Hildenbrand	1	-0/+24
	Let's use the generated groups to create feature group representations for the user. These groups can later be used to enable/disable multiple features in one shot and will be used to reduce the amount of reported features to the user if all subfeatures are in place. We want to work on features using ordinary bitmap operations, however we can't initialize a bitmap statically (unsigned long[] ...). Therefore we store the generated feature lists in separate arrays and convert them to a proper bitmaps before they will ever be used.

2016-09-06	s390x/cpumodel: introduce CPU features	Michael Mueller	1	-0/+69
	The patch introduces s390x CPU features (most of them refered to as facilities) along with their discription and some functions that will be helpful when working with the features later on. Please note that we don't introduce all known CPU features, only the ones currently supported by KVM + QEMU. We don't want to enable later on blindly any facilities, for which we don't know yet if we need QEMU support to properly support them (e.g. migrate additional state when active). We can update QEMU later on.
