Heiko Carstens 59f60af34a s390/sclp: Initialize sclp subsystem via arch_cpu_finalize_init() ... [ Upstream commit 3bcc8a1af5 ] With the switch to GENERIC_CPU_DEVICES an early call to the sclp subsystem was added to smp_prepare_cpus(). This will usually succeed since the sclp subsystem is implicitly initialized early enough if an sclp based console is present. If no such console is present the initialization happens with an arch_initcall(); in such cases calls to the sclp subsystem will fail. For CPU detection this means that the fallback sigp loop will be used permanently to detect CPUs instead of the preferred READ_CPU_INFO sclp request. Fix this by adding an explicit early sclp_init() call via arch_cpu_finalize_init().
