A set of scheduler fixes:

 - Address a load balancer regression by making the load balancer use the
   same logic as the wakeup path to spread tasks in the LLC domain.

 - Prefer the CPU on which a task run last over the local CPU in the fast
   wakeup path for asymmetric CPU capacity systems to align with the
   symmetric case. This ensures more locality and prevents massive
   migration overhead on those asymetric systems

 - Fix a memory corruption bug in the scheduler debug code caused by
   handing a modified buffer pointer to kfree().
