This introduces a much\nhigher load balancing rate than what is necessary.  The patch\nchanges the behavior by only doing idle load balancing on\nbehalf of an idle cpu only when it is due for load balancing.\n\nOn SGI's systems with over 3000 cores, the cpu responsible for idle balancing\ngot overwhelmed with idle balancing, and introduces a lot of OS noise\nto workloads.  This patch fixes the issue.\n\nChange-Id: I5c3a426db143f3eabf9b5b1f98f868aa21221402\nSigned-off-by: Tim Chen <tim.c.chen@linux.intel.com>\nAcked-by: Russ Anderson <rja@sgi.com>\nReviewed-by: Rik van Riel <riel@redhat.com>\nReviewed-by: Jason Low <jason.low2@hp.com>\nSigned-off-by: Peter Zijlstra <peterz@infradead.org>\nCc: Andrew Morton <akpm@linux-foundation.org>\nCc: Len Brown <len.brown@intel.com>\nCc: Dimitri Sivanich <sivanich@sgi.com>\nCc: Hedi Berriche <hedi@sgi.com>\nCc: Andi Kleen <andi@firstfloor.org>\nCc: MichelLespinasse <walken@google.com>\nCc: Peter Hurley <peter@hurleysoftware.com>\nCc: Linus Torvalds <torvalds@linux-foundation.org>\nLink: http://lkml.kernel.org/r/1400621967.2970.280.camel@schen9-DESK\nSigned-off-by: Ingo Molnar <mingo@kernel.org>\nSigned-off-by: franciscofranco <franciscofranco.1990@gmail.com>","distinct":true,"url":"https://api.github.com/repos/DirtyUnicorns/android_kernel_lge_bullhead/commits/e4f8ce27d2462ccc6be4f7d27d5e1371e77a292d"}]}
