I reduced it much further:
void __add_entropy_words(void);
void __wake_up(void);
void SHATransform(void);
static inline __attribute__((always_inline)) void 
add_entropy_words(void){}
void extract_entropy(void);
static inline __attribute__((always_inline)) void 
xfer_secondary_pool(void)
{
  extract_entropy();
  add_entropy_words();
}
void extract_entropy(void)
{
  xfer_secondary_pool();
  __wake_up();
}
void init_std_data(void)
{
 add_entropy_words();
}
void rand_initialize(void)
{
 init_std_data();
}
