[PATCH] for_each_online_pgdat: for_each_bootmem
Add a list_head to bootmem_data_t and make bootmems use it. bootmem list is
sorted by node_boot_start.
Only nodes against which init_bootmem() is called are linked to the list.
(i386 allocates bootmem only from one node(0) not from all online nodes.)
A summary:
1. for_each_online_pgdat() traverses all *online* nodes.
2. alloc_bootmem() allocates memory only from initialized-for-bootmem nodes.
