While userfaultfd, KVM's demand paging implementation, is not specific to KVM, having a benchmark for its performance will be useful for guiding performance improvements to KVM. As a first step towards creating a userfaultfd demand paging test, create a simple memory access test, based on dirty_log_test.

It's fine to start with x86-only for this test, but imho it would be better to mention that in cover letter, or reply to reviewer comments on that you removed aarch64 from previous post.
