Subject[PATCH v2 0/3] smp: Allow smp_call_function_single_async() to insert locked csd
Date
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.
