That does not work.
drivers/built-in.o: In function `.store_online':
cpu.c:(.ref.text+0xf5c): undefined reference to `.cpu_hotplug_driver_lock'
cpu.c:(.ref.text+0xfc8): undefined reference to `.cpu_hotplug_driver_unlock'
make: *** [.tmp_vmlinux1] Error 1
cpu_hotplug_driver_lock is only defined on pseries, but HOTPLUG_CPU is
also defined on pmac.
These two routines should be defined as a no-op if CONFIG_ARCH_CPU_PROBE_RELEASE
is not defined in linux/cpu.h. The update below should be in the patch set
you are looking at.
from linux/cpu.h:
#ifdef CONFIG_ARCH_CPU_PROBE_RELEASE
extern void cpu_hotplug_driver_lock(void);
extern void cpu_hotplug_driver_unlock(void);
#else
static inline void cpu_hotplug_driver_lock(void)
{
}
static inline void cpu_hotplug_driver_unlock(void)
{
}
#endif
