    x86-32, NUMA: use sparse_memory_present_with_active_regions() · 797390d8

    Instead of calling memory_present() for each region from NUMA init,
    call sparse_memory_present_with_active_regions() from paging_init()
    similarly to x86-64.
    
    For flat and numaq, this results in exactly the same memory_present()
    calls.  For srat, if there are multiple memory chunks for a node,
    after this change, memory_present() will be called separately for each
    chunk instead of being called once to encompass the whole range, which
    doesn't cause any harm and actually is the better behavior.
