The alloc_bootmem_pages_nopanic(size) is a shortcut for
__alloc_bootmem_nopanic(size, PAGE_SIZE, BOOTMEM_LOW_LIMIT) which allocates
PAGE_SIZE aligned memory. Since BOOTMEM_LOW_LIMIT is hardwired to 0 there
is no restrictions on where the allocated memory should reside.

The memblock_alloc_nopanic(size, PAGE_SIZE) also allocates PAGE_SIZE
aligned memory without any restrictions and thus can be used as a
replacement for alloc_bootmem_pages_nopanic()
