This patch series implements SMP boot for arch/arm, as far as getting all CPUs up and running the idle loop. Changes from v1: - moved barriers out of loop in udelay() - dropped broken GIC change in favour of explanatory comment - made the increment of ready_cpus atomic (I couldn''t move the increment to before signalling the next CPU because the PT switch has to happen between
