I didn't use alloc_bootmem because I thought alloc_bootmem was
very simple allocator and we should not use it to allocate
arbitrary size (not PAGE_SIZE * n) of memory so frequently.
But I don't know about it very much and my understanding might
be incorrect.

Can I use alloc_bootmem as well as kmalloc to allocate arbitrary
size of memory?
