Today's linux-next now runs into a warning on arm64 and
presumably others, with the same problem as on arm earlier:

WARNING: unmet direct dependencies detected for KEXEC
  Depends on [n]: ARCH_SUPPORTS_KEXEC [=n]
  Selected by [y]:
  - CRASH_DUMP [=y] && ARCH_SUPPORTS_CRASH_DUMP [=y]

I think the easiest way to make this reliable would be
this fixup.
