Does anybody know why the APIC state loaded by the first call to
kvm_arch_get_registers() is wrong, in the first place? What exactly is
different in the APIC state in the second kvm_arch_get_registers() call,

Move the registering of CPU reset handlers to before the point where
we leave the function in the -bios (not -kernel) case, so CPU reset
works correctly with -bios as well.

Until now, when a s390 cpu was stopped or halted, the number of running
