Log Message:
Pull up following revision(s) (requested by riastradh in ticket #508):
distrib/sets/lists/comp/mi: revision 1.2294
share/man/man9/Makefile: revision 1.443
sys/sys/atomic.h: revision 1.18
share/man/man9/atomic_loadstore.9: revision 1.1
share/man/man9/atomic_loadstore.9: revision 1.2
New atomic load/store operations for the kernel.
Guarantee no fusing and no tearing, and can optionally impose
ordering relative to other memory operations.
Unordered:
- atomic_load_relaxed
- atomic_store_relaxed
Ordered:
- atomic_load_acquire
- atomic_load_consume
- atomic_store_release
These are intended to match C11 semantics, and can be defined in
terms of the C11 atomic API when ready.
Document relation to atomic_ops(3) and membar_ops(3).
