Merge branch 'irq/core-v6' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into irq/core
Pull hardirq and softirq nesting updates from Frederic Weisbecker,
which fix nesting related stack overruns such as:
http://lkml.kernel.org/r/1378330796.4321.50.camel%40pasglop
Beyond being a fix, this series also optimizes and reorganizes arch
hardirq/softirq stack processing to be faster and more robust.
