In a config file from "kernel test robot <lkp@xxxxxxxxx>" for a
different problem, this linker error was exposed when
CONFIG_IA64_MCA_RECOVERY=m.
We could either export make_task_dead() or restrict IA64_MCA_RECOVERY
to a bool Kconfig symbol instead of a tristate symbol, so go with the
EXPORT_SYMBOL() path.
Fixes this build error:
ERROR: modpost: "make_task_dead" [arch/ia64/kernel/mca_recovery.ko] undefined!
Fixes: 0e25498f8cd4 ("exit: Add and use make_task_dead.")
