When CONFIG_KEXEC_FILE=y but CONFIG_KEXEC is not set:
kernel/kexec_core.o: In function `kimage_free':
kexec_core.c:(.text+0xa0c): undefined reference to `machine_kexec_cleanup'
kernel/kexec_core.o: In function `.L0 ':
kexec_core.c:(.text+0xde8): undefined reference to `machine_crash_shutdown'
kexec_core.c:(.text+0xdf4): undefined reference to `machine_kexec'
kernel/kexec_core.o: In function `.L231':
kexec_core.c:(.text+0xe1c): undefined reference to `riscv_crash_save_regs'
kernel/kexec_core.o: In function `.L0 ':
kexec_core.c:(.text+0x119e): undefined reference to `machine_shutdown'
kernel/kexec_core.o: In function `.L312':
kexec_core.c:(.text+0x11b2): undefined reference to `machine_kexec'
kernel/kexec_file.o: In function `.L0 ':
kexec_file.c:(.text+0xb84): undefined reference to `machine_kexec_prepare'
kernel/kexec_file.o: In function `.L177':
kexec_file.c:(.text+0xc5a): undefined reference to `machine_kexec_prepare'
Makefile:1160: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1
These symbols should depend on CONFIG_KEXEC_CORE rather than CONFIG_KEXEC
when kexec_file has been implemented on RISC-V, like the other archs have
done.
