MIPS: smp-cps: function to determine whether CPS SMP is in use (68c1232f) · Commits · 戴 / test

The core power down state for cpuidle will require that the CPS SMP implementation is in use. This patch provides a mips_cps_smp_in_use function which determines whether or not the CPS SMP implementation is currently in use. Signed-off-by:
