  "message": "tick: Dynamically set broadcast irq affinity\n\nWhen a cpu goes to a deep idle state where its local timer is\nshutdown, it notifies the time frame work to use the broadcast timer\ninstead.  Unfortunately, the broadcast device could wake up any CPU,\nincluding an idle one which is not concerned by the wake up at all. So\nin the worst case an idle CPU will wake up to send an IPI to the CPU\nwhose timer expired.\n\nProvide an opt-in feature CLOCK_EVT_FEAT_DYNIRQ which tells the core\nthat is should set the interrupt affinity of the broadcast interrupt\nto the cpu which has the earliest expiry time. This avoids unnecessary\nspurious wakeups and IPIs.\n\n[ tglx: Adopted to cpumask rework, silenced an uninitialized warning,\n  massaged changelog ]\n\nSigned-off-by: Daniel Lezcano \u003cdaniel.lezcano@linaro.org\u003e\nCc: viresh.kumar@linaro.org\nCc: jacob.jun.pan@linux.intel.com\nCc: linux-arm-kernel@lists.infradead.org\nCc: santosh.shilimkar@ti.com\nCc: linaro-kernel@lists.linaro.org\nCc: patches@linaro.org\nCc: rickard.andersson@stericsson.com\nCc: vincent.guittot@linaro.org\nCc: linus.walleij@stericsson.com\nCc: john.stultz@linaro.org\nLink: http://lkml.kernel.org/r/1362219013-18173-3-git-send-email-daniel.lezcano@linaro.org\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n\nChange-Id: I6a880a39dd595526b80a6d72b88be74163513da9\nSigned-off-by: Karthik Parsha \u003ckparsha@codeaurora.org\u003e\nSigned-off-by: Mahesh Sivasubramanian \u003cmsivasub@codeaurora.org\u003e\n",
