[PATCH 0 of 9] (v2) arm: SMP boot
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
