    cpumask: centralize cpu_online_map and cpu_possible_map · 98a79d6a

    Impact: cleanup
    
    Each SMP arch defines these themselves.  Move them to a central
    location.
    
    Twists:
    1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
       CONFIG_INIT_ALL_POSSIBLE for this rather than break them.
    
    2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
       Those archs simply have phys_cpu_present_map replaced everywhere.
    
    3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
       so I just manipulate them both in sync.
    
    4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
       declarations.
