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 Acked-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
