It is like a reboot As this KEXEC_CORE is appearing in all arch/*/Kconfig files, I think it's time to add an ARCH_HAS_KEXEC symbol (to a common Kconfig file), and let arch/*/Kconfig select that if the architecture has kexec support. Then KEXEC and KEXEC_CORE can live in the common Kconfig file, without the need to duplicate it.
