The patch titled
sched: add discrete weighted cpu load function
has been removed from the -mm tree. Its filename is
sched-add-discrete-weighted-cpu-load-function.patch
This patch was dropped because it was folded into sched-implement-smpnice.patch
------------------------------------------------------
Subject: sched: add discrete weighted cpu load function
From: Con Kolivas <kernel@xxxxxxxxxxx>
When the type of weighting is known to be zero we can use a simpler version
of source_load with a weighted_cpuload() function. Export that function to
allow relative weighted cpu load to be used by other subsystems if desired.
