[PATCH locking/atomics 0/19] Add kernel-doc for more atomic operations

[Paul E. McKenney]

Hello!

This series adds kernel-doc for additional atomic operations by adding
them to the gen-atomics.sh-based scripting.  This ends up duplicating
a few entries currently in x86, which this series removes in order to
avoid duplicate-entry warnings from "make htmldocs".

1.	locking/atomic: Fix fetch_add_unless missing-period typo.

2.	locking/atomic: Add "@" before "true" and "false" for fallback
	templates.

3.	locking/atomic: Add kernel-doc and docbook_oldnew variables
	for headers.

4.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_${pfx}inc${sfx}${order}.

5.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_${pfx}dec${sfx}${order}.

6.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_${pfx}andnot${sfx}${order}.

7.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_try_cmpxchg${order}.

8.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_dec_if_positive.

9.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_dec_unless_positive.

10.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_inc_unless_negative.

11.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_set_release.

12.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_read_acquire.

13.	locking/atomic: Script to auto-generate acquire, fence, and
	release headers.

14.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_${pfx}${name}${sfx}_acquire.

15.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_${pfx}${name}${sfx}_release.

16.	locking/atomic: Add kernel-doc header for
	arch_${atomic}_${pfx}${name}${sfx}.

17.	x86/atomic.h: Remove duplicate kernel-doc headers.

18.	locking/atomic: Refrain from generating duplicate fallback
	kernel-doc.

19.	Add atomic operations to the driver basic API documentation.

Aside:  There was much much less drama and pain involved in installing
and running "make htmldocs" than last time around.  A big "thank you!"
to whoever made this happen.  Here is hoping for a similar degree of
improvement for the next required upgrade!  ;-)

						Thanx, Paul
