kernel: enable core scheduling on 5.14+ kernels
Core scheduling is a recent innovation in newer kernels to help run
certain untrusted compute workloads more safely in the face of
vulnerabilities like Spectre. In short: it lets processes assign a
unique "cookie" to some group of processes to indicate they are allowed
to be scheduled together on the same SMT-capable core. This helps
mitigate attacks that rely on observing usage of CPU execution units by
cohabitated threads.
Some extra details are available via Linux Weekly News:
