Need cross compile tutorials.

I think I find the key, I build kexec, kexecboot with klibc, and the size is correct now.

That's nice, have you also tried to boot it on the Z?

I had tried but something works wrong, I'm still working on that.

Attached the 4.14.18 kernel .config for void linux kexecboot and the initramfs. This should help you get going.
Source is same as https://github.com/greguu/linux-4.14.18-c3x00

Sorry, seems the config file is missed, can you reupload it?

Do you mean the kexecboot.tar.gz attached to that post? I have successfully downloaded it, and I have seen it contains a .config and a initramfs.cpio.xz archive. Is the .config file the one you are searching for?

Sorry, my mistake, I ignored the hidden file.

Yes that is the way, use klibc or glibc and make sure to "strip" the binary, too.  I have not tried musl for kexecboot, but should also work
