    [IA64] Minimize per_cpu reservations. · 2c6e6db4
    holt@sgi.com authored
    This attached patch significantly shrinks boot memory allocation on ia64.
    It does this by not allocating per_cpu areas for cpus that can never
    exist.
    
    In the case where acpi does not have any numa node description of the
    cpus, I defaulted to assigning the first 32 round-robin on the known
    nodes..  For the !CONFIG_ACPI  I used for_each_possible_cpu().
