Hello, Ingo,

The changes in this series include:

1. Streamline RCU's use of per-CPU variables, shifting from "cpu"
arguments to functions to "this_"-style per-CPU variable accessors.
These were posted to LKML at https://lkml.org/lkml/2014/10/28/1130.

2. Documentation updates. These were posted to LKML at
https://lkml.org/lkml/2014/10/28/1145.

3. Miscellaneous fixes. These were posted to LKML at
https://lkml.org/lkml/2014/10/28/1161.

4. Signal-handling RCU updates. These were posted to LKML at
https://lkml.org/lkml/2014/10/28/1172.

5. Real-time updates. These were posted to LKML at
ttps://lkml.org/lkml/2014/10/28/1181.

6. Torture-test updates. These were posted to LKML at
https://lkml.org/lkml/2014/10/28/1204.

Note that a few commits posted to LKML have been deferred, in particular,
there is some possibility that the DEC Alpha guys will make the compiler
changes needed to allow pre-EV56 CPUs to safely access chars and shorts.

All of these have been exposed to -next testing.
These changes are available in the git repository at:
