Whereas, since we will drop the select of KEXEC for CRASH_DUMP in kernel/Kconfig.kexec, compiling error will be triggered if below config items are set: === CONFIG_CRASH_CORE=y CONFIG_KEXEC_CORE=y CONFIG_CRASH_DUMP=y === --------------------------------------------------------------- loongarch64-linux-ld: kernel/kexec_core.o: in function `.L209': >> kexec_core.c:(.text+0x1660): undefined reference to `machine_kexec_cleanup' loongarch64-linux-ld: kernel/kexec_core.o: in function `.L287': >> kexec_core.c:(.text+0x1c5c): undefined reference to `machine_crash_shutdown' >> loongarch64-linux-ld: kexec_core.c:(.text+0x1c64): undefined reference to `machine_kexec' loongarch64-linux-ld: kernel/kexec_core.o: in function `.L2^B5': >> kexec_core.c:(.text+0x2090): undefined reference to `machine_shutdown' loongarch64-linux-ld: kexec_core.c:(.text+0x20a0): undefined reference to `machine_kexec' --------------------------------------------------------------- Here, changing the dependency of machine_kexec.o relocate_kernel.o to CONFIG_KEXEC_CORE can fix above building error.
