Biederman, an SMT/MC balancing fix from Suresh Siddha (we under-balanced) and another fix from Suresh for debugging tweak side-effect. Plus there's a sched_clock() quality fix for CPUs that stop the TSC in idle (acked by Len Brown) and a reniced-tasks fixlet. the SMT/MC blancing fix has the highest risk - but since it causes slightly more balancing (instead of less balancing, which is the more risky action) it should be pretty safe. Key workloads still seem fine. Tested on 32-bit and 64-bit x86 and it has passed 200+ make randconfig build tests.
