Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull RCU updates from Ingo Molnar:
 "These are the main changes in this cycle:

    - Streamline RCU's use of per-CPU variables, shifting from "cpu"
      arguments to functions to "this_"-style per-CPU variable
      accessors.

    - signal-handling RCU updates.

    - real-time updates.

    - torture-test updates.

    - miscellaneous fixes.

    - documentation updates"

identical, as noted earlier, the compiler could pull this store outside

You must also be careful not to rely too much on boolean short-circuit
evaluation. Consider this example:
q = ACCESS_ONCE(a);
if (a || 1 > 0)
ACCESS_ONCE(b) = 1;
Because the second condition is always true, the compiler can transform
this example as following, defeating control dependency:
q = ACCESS_ONCE(a);
ACCESS_ONCE(b) = 1;
This example underscores the need to ensure that the compiler cannot
out-guess your code. More generally, although ACCESS_ONCE() does force
the compiler to actually emit code for a given load, it does not force
the compiler to use the results.
Finally, control dependencies do -not- provide transitivity. This is
demonstrated by two related examples, with the initial values of
x and y both being zero:
