-	prefetch(x) attempts to pre-emptively get the memory pointed to
-	by address "x" into the CPU L1 cache. 
-	prefetch(x) should not cause any kind of exception, prefetch(0) is
-	specifically ok.
-
-	prefetch() should be defined by the architecture, if not, the 
-	#define below provides a no-op define.	
-	
-	There are 3 prefetch() macros:
-	
-	prefetch(x)  	- prefetches the cacheline at "x" for read
-	prefetchw(x)	- prefetches the cacheline at "x" for write
-	spin_lock_prefetch(x) - prefetches the spinlock *x for taking
-	
-	there is also PREFETCH_STRIDE which is the architecure-preferred 
-	"lookahead" size for prefetching streamed operations.
