Ah - i have messed up my sched-devel.git script so the git-push went to but into my home directory :-/ Should work now - let me know
if it doesnt.

i've also uploaded the patch series in quilt format, to:

sched: remove precise CPU load calculations #2

sched: remove precise CPU load
3 files changed, 9 insertions(+), 41 deletions(-)

sched: remove stat_gran
