In the beginning, mm/gup_benchmark.c supported get_user_pages_fast()
only, but right now, it supports the benchmarking of a couple of
get_user_pages() related calls like:
* get_user_pages_fast()
* get_user_pages()
* pin_user_pages_fast()
* pin_user_pages()
The documentation is confusing and needs update.
