Please do.

I did a

  grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')

but there are drivers out there that have that "prefetch()" pattern
without being about actual CPU prefetching at all (see for example
drivers/ide/cmd640.c), so once I got allyesconfig with my x86
detection hack going, I didn't bother with the few odd men out.
