If we use NO_BOOTMEM, we don't need to initialize a bitmap and
we don't need to do bitmap operation, so we can boot slightly faster.
Additionaly advantage of enabling NO_BOOTMEM is saving more memory.
bootmem allocator manage memories as page unit, so if we request
4 bytes area to bootmem, it actually give us PAGE_SIZE area.
nobootmem manage memory as byte unit, so there is no waste.
