I proposed and implemented the hashtable-based state tree API in the
previous patch "kexec: add Kexec HandOver (KHO) generation helpers" [1]
and then added `select XXHASH` here. If one line of change is not
qualified for "Co-developed-by", I will remove it from the commit message
in the next version.
