lakitu: Enable CONFIG_SCHED_CORE in Linux kernel.
This option permits Core Scheduling, a means of coordinated task selection across SMT siblings. When enabled task selection ensures that all SMT siblings will execute a task from the same 'core group', forcing idle when no matching task is found.
Use of this feature includes:
- mitigation of some (not all) SMT side channels;
- limiting SMT interference to improve determinism and/or performance.
