This series contains a few documentation updates: 1. Records limitations of bitfields and small variables. Also rules out pre-EV56 Alpha, which lack 8- and 16-bit memory-reference instructions. Later Alpha CPUs are OK. (The official Alpha maintainers have thus far been silent on this patch.) 2. Document the new RCU self-test boot parameters, courtesy of Pranith Kumar. 3. Records that short-circuit boolean evaluation does not necessarily defend against control-dependency breakage by compiler optimizations. 4. Add mention of atomic_long_t to atomic_ops.txt. 5. Fix an example in memory-barriers.txt, courtesy of Pranith Kumar. Thanx, Paul ------------------------------------------------------------------------ b/Documentation/atomic_ops.txt | 12 +++-- b/Documentation/kernel-parameters.txt | 9 ++++ b/Documentation/memory-barriers.txt | 71 ++++++++++++++++++++++++++++------ 3 files changed, 77 insertions(+), 15 deletions(-)
