1) uml kernel bootmem managed through bootmem_data->node_bootmem_map,
not struct page array, so it is unnecessary.
2) the struct page array allocate has been pointer by a *loacl* pointer
struct page *map in init_maps function. The array can't be access after
the init_maps exit. As a result, there is about 1% of total memory leak.
