The spdif root clock may be used by other module or defined with
CLK_SET_RATE_GATE, so we can't change the clock rate in driver.
In this patch remove the clk_set_rate and clk_round_rate to protect the

Unroll clear_page 8 times. A simple microbenchmark which
allocates and frees a zeroed page:
for (i = 0; i iterations; i++) {
unsigned long p = __get_free_page(GFP_KERNEL | __GFP_ZERO);
free_page(p);
}
improves 20% on POWER8.
This assumes cacheline sizes won't grow beyond 512
