QingFeng Hao 3d8757b87d s390/sthyi: add s390_sthyi system call ... Add a syscall of s390_sthyi to implement STHYI instruction in LPAR which reuses the implementation for KVM by Janosch Frank - commit 95ca2cb579 ("KVM: s390: Add sthyi emulation"). STHYI(Store Hypervisor Information) is an emulated z/VM instruction that provides a guest with basic information about the layers it is running on. This includes information about the cpu configuration of both the machine and the lpar, as well as their names, machine model and machine type. This information enables an application to determine the maximum capacity of CPs and IFLs available to software. For the arguments of s390_sthyi, code shall be 0 and flags is reserved for future use, info is the output argument to store the required hypervisor info.
