  "message": "Use num_possible_cpus() instead of NR_CPUS for timer distribution\n\nTo avoid lock contention, we distribute the sched_timer calls across the\ncpus so they do not trigger at the same instant.  However, I used NR_CPUS,\nwhich can cause needless grouping on small smp systems depending on your\nkernel config.  This patch converts to using num_possible_cpus() so we\nspread it as evenly as possible on every machine.\n\nBriefly tested w/ NR_CPUS\u003d255 and verified reduced contention.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
