plain text document attachment (critical_mempools)
Fixup existing mempool users to use the new mempool API, part 2.
This patch fixes up all the trivial mempool users, all of which are basically
currently just wrappers around kmalloc(). Change these functions to
call kmalloc_node() with their shiny new 'node_id' argument.
Possible further work: Many of these functions could be replaced by a single
common mempool_kmalloc() function, storing the size to kmalloc in pool_data.
