  "message": "timers: Cache __next_timer_interrupt result\n\nEach time a cpu goes to sleep on a NOHZ\u003dy system the timer\nwheel is searched for the next timer interrupt. It can take\nquite a few cycles to find the next pending timer.\n\nThis patch adds a field to tvec_base that caches the result of\n__next_timer_interrupt.\n\nThe hit ratio is around 80% on my thinkpad under normal use, on\na server I\u0027ve seen hit ratios from 5% to 95% dependent on the\nworkload.\n\n-v2: jiffies wrap fixes\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Venki Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nLKML-Reference: \u003c20090721202505.7d56a079@skybase\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
