/*
* memset_volatile is a volatile pointer to the memset function.
* You can call (*memset_volatile)(buf, val, len) or even
* memset_volatile(buf, val, len) just as you would call
* memset(buf, val, len), but the use of a volatile pointer
* guarantees that the compiler will not optimise the call away.
