commit dbecf9b8b8ce580f4e11afed9d61e8aa294cddd2 upstream.
In linux-next, IA64_MCA_RECOVERY uses the (new) function make_task_dead(), which is not exported for use by modules. Instead of exporting it for one user, convert IA64_MCA_RECOVERY to be a bool Kconfig symbol.
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.
Fixes this build error:
ERROR: modpost: "make_task_dead" [arch/ia64/kernel/mca_recovery.ko] undefined!
