[RFC][Patch 06/18] sched: update source_load(), target_load() and weighted_cpuload() to use u64

From: Nikhil Rao
Date: Wed Apr 20 2011 - 16:54:20 EST


source_load(), target_load() and weighted_cpuload() refer to values in
rq->cpu_load, which is now u64. Update these functions to return u64 as well.
