* Enforced block prefetch. This function loads the specified amount
* `prefetch_length' of memory from the specified address `addr' to CPU
* cache with each loaded cache line being the size of `cache_line_length'.
- * If you don't know the cache line size use 32 bytes. Note that, the
+ * If you don't know the cache line size use 64 bytes. Note that, the
* `cache_line_length' is a const int. In this context this mean its
* value must not come from a variable but must be a constant (the code
* won't compile if it comes from a variable).
*
* The `prefetch_length' must be multiple of twice of the
- * `cache_line_length' or 64 if you don't know the cache line size, hence
- * the minimum length for `prefetch_length' is 64 bytes when the
- * `cache_line_length' is 32 bytes.
+ * `cache_line_length' or 128 if you don't know the cache line size, hence
+ * the minimum length for `prefetch_length' is 128 bytes when the
+ * `cache_line_length' is 64 bytes. Shorter cache line length (32 bytes)
+ * can be used too.
*
* You should use the correct `cache_line_length' value for your CPU or
* the value of the CPU for which you want to optimize your code. Intel
- * CPUs usually have cache size of 32 or 64 bytes, or both when there are
- * multiple caches. The most optimal prefetch is achieved if the
- * `cache_line_length' is the actual CPU cache line size. Always do
- * performance testing with and without prefetching to make sure the
- * prefetch actually helps. If used improperly, it may slow down your
- * program.

* The difference to silc_prefetch is that this function always performs
* the prefetch and has the ability to prefetch more than one cache line
