After manually applying the patch, the build is failing with the following
error:
build failed with error "arch/powerpc/kexec/elf_64.o: In function
`elf64_verify_sig':
/root/kernel/linus/linux/arch/powerpc/kexec/elf_64.c:160: undefined
reference to `verify_appended_signature'"
This patch does not add call to verify_appended_signature.
Maybe you applied the following patch as well?
Yes, I tried build after applying all the patches.
Thanks & Regards,
