Idle notifier not registered if CONFIG_X86_32 is defined,
those callbacks are empty for X86_32 platform.
ifdef CONFIG_X86_64
void enter_idle(void);
void exit_idle(void);
else
static inline void enter_idle(void) { }
static inline void exit_idle(void) { }
static inline void __exit_idle(void) { }
endif
Make this work on X86_32 platforms by
removing the restriction for X86_64
