This patchset relocates code to make sd_llc_shared->has_idle_cores
available to other scheduling classes and updates the sched_ext built-in
idle CPU selection policy to make use of it.
Andrea Righi (3):
sched: Relocate sched_smt_present definition to core.c
sched: Expose sd_llc_shared->has_idle_cores to other sched classes
sched_ext: idle: Reuse sd_llc_shared->has_idle_cores
