      [S390] Get rid of additional_cpus kernel parameter. · 48483b32

      It caused only a lot of confusion. From now on cpu hotplug of up to
      NR_CPUS will work by default. If somebody wants to limit that then
      the possible_cpus parameter can be used.

      [S390] Standby cpu activation/deactivation. · 08d07968
      Heiko Carstens authored
      
      
      Add a new interface so that cpus can be put into standby state and
      configured state.
      Only offline cpus can be put into standby state or configured state.
      For that the new percpu sysfs attribute "configure" must be used.
      To put a cpu in standby state a "0" must be written to the attribute.
      In order to switch it into configured state a "1" must be written to
      the attribute.
      Only cpus in configured state can be brought online.
      In addition this patch introduces a static mapping of physical to
      logical cpus. As a result only the sysfs directories of present cpus
      will be created. To scan for new cpus the new sysfs attribute "rescan"
      must be used.
      Writing to /sys/devices/system/cpu/rescan will trigger a rescan of
      cpus and will create directories for new cpus.
      
      On IPL only configured cpus will be used. And on reboot/shutdown all
      cpus will remain in their current state (configured/standby).
