As per Peter Zijlstra's review, these are the difference wrt V1:

* inclusion of appropriate header file linux/prefetch.h
* factorized the calls to prefetch into a separate function
* introduction of the local variable curr as a form of compiler
  subexpression elimination (CSE)
* fixed Signed-off-by chain
* added comment as per why the prefetches are needed
