Well, it does not:
CC s390x-softmmu/target-s390x/cpu.o
/users/gleb/work/qemu/target-s390x/cpu.c: In function 's390_cpu_reset':
/users/gleb/work/qemu/target-s390x/cpu.c:89:9: error: implicit
declaration of function 'kvm_arch_reset_vcpu'
[-Werror=implicit-function-declaration]
/users/gleb/work/qemu/target-s390x/cpu.c:89:9: error: nested extern
declaration of 'kvm_arch_reset_vcpu' [-Werror=nested-externs]
cc1: all warnings being treated as errors
