                          a null pointer was returned by a lookup_address() call.

* How do you think about to add any tags (like “Fixes” and “Cc”) accordingly?
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.12#n145

* Would a summary phrase like “Prevent null pointer dereference in snp_kexec_finish()”
  be a bit nicer?
