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.
