In general, *all* atomic accesses on read-only memory are Undefined Behavior. For instance, attempting +//! to do a `compare_exchange` that will definitely fail (making it conceptually a read-only +//! operation) can still cause a page fault if the underlying memory page is mapped read-only. Since +//! atomic `load`s might be implemented using compare-exchange operations, even a `load` can fault +//! on read-only memory. +//! +//! For the purpose of this section, "read-only memory" is defined as memory that is read-only in +//! the underlying target, i.e., the pages are mapped with a read-only flag and any attempt to write +//! will cause a page fault. In particular, an `&u128` reference that points to memory that is +//! read-write mapped is *not* considered to point to "read-only memory".

As an exception from the general rule stated above, "sufficiently small" atomic loads with +//! `Ordering::Relaxed` are implemented in a way that works on read-only memory, and are hence not +//!
