This should hopefully be the last posting of this series -- people felt it
needed one more mostly because last time I typoed the linux-kernel email
address.
If there are no further comments, Ingo will merge these patches in the next few
days.

These patches introduce 2 new barrier primitives:
smp_load_acquire(p)
smp_store_release(p, v)
See the first patch, which changes Documentation/memory-barriers.txt, to find
the exact definitions of what an ACQUIRE/RELEASE barrier is -- previously known
as LOCK/UNLOCK barriers.
The second patch moves the smp_mb__{before,after}_atomic_{dec,inc}() barriers
to asm/atomic.h for arc and hexagon -- they were already there for all other archs.
This cleans up asm/barrier.h, and the third patch makes more agressive use of
asm-generic/barrier.h to implement the simple cases.
Then the fourth patch adds the new primitives.
Previous versions were widely build tested -- this version is not, but it also
not significantly different.
These patches apply to:
tip/master
