I meant using init/kerntypes.o directly instead of copying it
to Kerntypes.  But after looking more into the build process
I've now noticed that Kerntypes isn't actually linked into
vmlinux at all.  But as it's a separate file you don't need
the ifdef CONFIG_CRASH_DUMP - people not wanting on their
potentially small root filesystems just don't have to copy
it.  That would be the last ifdef on CONFIG_CRASH_DUMP, so
dump.o can now be loaded into any kernel with the patch
applied.  cool! :)
