Documentation/atomic_t.txt and Documentation/atomic_bitops.txt _should_
cover all of it I _think_. If there's anything mising, please tell and
we'll write more documents.

And I suppose we should ammend atomic_bitops.txt with a reference to
include/asm-generic/bitops/atomic.h which fully implements the atomic
bitops using atomic_t.
