Eric Farman 68c557501b KVM: s390: Allocate and save/restore vector registers ... Define and allocate space for both the host and guest views of the vector registers for a given vcpu. The 32 vector registers occupy 128 bits each (512 bytes total), but architecturally are paired with 512 additional bytes of reserved space for future expansion. The kvm_sync_regs structs containing the registers are union'ed with 1024 bytes of padding in the common kvm_run struct. The addition of 1024 bytes of new register information clearly exceeds the existing union, so an expansion of that padding is required. When changing environments, we need to appropriately save and restore the vector registers viewed by both the host and guest, into and out of the sync_regs space. The floating point registers overlay the upper half of vector registers 0-15, so there's a bit of data duplication here that needs to be carefully avoided.
