[PATCH v2 RFC 0/3] Memory-barrier documentation updates

Paul E. McKenney

Hello!

This series applies some long-needed updates to memory-barriers.txt:

1. Add ACCESS_ONCE() calls where needed to ensure their inclusion
in code copy-and-pasted from this file.

2. Add long atomic examples alongside the existing atomics.

3. Prohibit architectures supporting the Linux kernel from
speculating stores.

Changes from v1:

o Combined with Peter Zijlstra's speculative-store-prohibition patch.

o Added more pitfalls to avoid when prohibiting speculative
stores, along with how to avoid them.

o Applied Josh Triplett's review comments.

Thanx, Paul
