Message-Id: <1303332697-16426-10-git-send-email-ncrao@google.com> Date: Wed, 20 Apr 2011 13:51:28 -0700 From: Nikhil Rao <ncrao@...gle.com> To: Ingo Molnar <mingo@...e.hu>, Peter Zijlstra <peterz@...radead.org> Cc: Paul Turner <pjt@...gle.com>, Mike Galbraith <efault@....de>, linux-kernel@...r.kernel.org, Nikhil Rao <ncrao@...gle.com> Subject: [RFC][Patch 09/18] sched: update division in cpu_avg_load_per_task to use div_u64 This patch updates the division in cpu_avg_load_per_task() to use div_u64, so that it works on 32-bit. We do not convert avg_load_per_task to u64 since this can be atmost 2^28, and fits into unsigned long on 32-bit.
