Ok, looks like I reversed 2 set of results yesterday when I posted. Here is a more complete (and hopefully accurate) reporting of the 3 patches.

A) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch
degrades volanomark, specjbb and specsdet

B) *** test5 + sched-balance-fix-2.6.0-test3-mm3-A0.patch
improves specjbb with no real change on sdet or volanomark

C) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch + sched-balance-fix-2.6.0-test3-mm3-A0.patch
degrades volanomark and sdet, more degrade than improvement on specjbb

D) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch + sched-balance-fix-2.6.0-test3-mm3-A0.patch + sched-2.6.0-test2-mm2-A3.patch
degrades volanomark and sdet, mixed results on specjbb



Below are the details for each of the runs.
