In a config file from "kernel test robot <lkp@intel.com>" 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!
