[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
