Convert the low level SMP assembly code for SH-Mobile ARM from using the INIT to the CPUINIT section. This unbreaks onlining of CPUs using the CPU hotplug interface: echo 1 > /sys/devices/system/cpu/cpu1/online Without this fix the reset vector code used by CPU hotplug will be freed as init section data and CPU cores cannot be brought online.
