Kirill A. Shutemov 64c349f4ae mm: add infrastructure for get_user_pages_fast() benchmarking 
Performance of get_user_pages_fast() is critical for some workloads, but
it's tricky to test it directly.

This patch provides /sys/kernel/debug/gup_benchmark that helps with
testing performance of it.

See tools/testing/selftests/vm/gup_benchmark.c for userspace
counterpart.
