180c12fb22 KVM: s390: rename private structures
While doing some tests with our lcrash implementation I have seen a
naming conflict with prefix_info in kvm_host.h vs. addrconf.h

To avoid future conflicts lets rename private definitions in
asm/kvm_host.h by adding the kvm_s390 prefix.

f603f0731f KVM: s390: rename stfl to kvm_stfl
Temporarily rename this function to avoid merge conflicts and/or
dependencies. This function will be removed as soon as git-s390
and kvm.git are finally upstream.

453423dce2 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
