This v2 introduced two more patches to let mips/kernel/smp.c and kernel/sched/core.c to start using the new feature, then we can drop the customized implementations.
One thing to mention is that cpuidle_coupled_poke_pending is another candidate that we can consider, however that cpumask is special in that it's not only used for singleton test of the per-vcpu csd when injecting new calls, but also in cpuidle_coupled_any_pokes_pending() or so to check whether there's any pending pokes. In that sense it should be good to still keep the mask because it could be faster than looping over each per-cpu csd.
Patch 1 is the same as v1, no change. Patch 2-3 are new ones.
Smoke tested on x86_64 only.
Please review, thanks.
