vrealloc_node()?! There is no such thing in the tree.
There are various k[zm]alloc_node() which are artifacts of the past
when NUMA just appeared and people cared about CONFIG_NUMA vs not.
Nowadays NUMA is everywhere and any new code must support NUMA
from the start. Hence no point in carrying old baggage and obsolete names.
