Merge commit '8700c95adb' into timers/nohz
The full dynticks tree needs the latest RCU and sched upstream updates in order to fix some dependencies. Merge a common upstream merge point that has these updates. Conflicts: include/linux/perf_event.h kernel/rcutree.h kernel/rcutree_plugin.h Signed-off-by: Frederic Weisbecker <[email protected]>

alloc_snapshot [FTRACE]

Allocate the ftrace snapshot buffer on boot up when the

main buffer is allocated. This is handy if debugging
