The patch series uses a couple of functions defined in
arch/powerpc/kexec/ranges.c. Since this file
only builds when CONFIG_KEXEC_FILE is set, we are encountering this
build issue.
If CONFIG_KEXEC_FILE is set, then this issue is not observed.
I will fix the above warnings and post the next version.
Thanks,
Sourabh
