KVM: s390: intercepts for privileged instructions
This patch introduces in-kernel handling of some intercepts for privileged
instructions:
handle_set_prefix() sets the prefix register of the local cpu
handle_store_prefix() stores the content of the prefix register to memory
handle_store_cpu_address() stores the cpu number of the current cpu to memory
handle_skey() just decrements the instruction address and retries
handle_stsch() delivers condition code 3 "operation not supported"
handle_chsc() same here
handle_stfl() stores the facility list which contains the
capabilities of the cpu
handle_stidp() stores cpu type/model/revision and such
handle_stsi() stores information about the system topology
