Changes from v2: - Fixed a bug in context switching in the percpu patch - Added two new patches, not strictly for SMP boot, but related, and apply after this series: - Poison, unmap and free the __init* areas after boot. - Use 'WFI' to take the CPu to a low power state in 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 them) - Made secondary CPUs come up directly on the idle vcpus' stacks, avoiding the whole business of allocating and tracking boot stacks. - Added a new patch to do late-boot MMU fixups on secondary CPUs. Cheers, Tim.
