[PATCH 2/2] powerpc: Enable ASYM_SMT on interleaved big-core systems

From: "Gautham R. Shenoy" Each of the SMT4 cores forming a fused-core are more or less independent units. Thus when multiple tasks are scheduled to run on the fused core, we get the best performance when the tasks are spread across the pair of SMT4 cores. Since the threads in the pair of SMT4 co
