Linux 3.16 compat: smp_mb__after_clear_bit()
The smp_mb__{before,after}_clear_bit functions have been renamed smp_mb__{before,after}_atomic. Rather than adding a compatibility function to handle this the code has been updated to use smp_wmb(). This has the advantage of being a stable functionally equivalent interface. On many architectures smp_mb__after_clear_bit() expands to smp_wmb(). Others might be able to do something slightly more efficient but this will be safe and correct on all of them.
