I'm running v5.1.0 trying to kexec into v5.1.1. I get an error when
trying to load the kernel image, I enabled some debugging of
arch/x86/kernel/machine_kexec_64.c and got the following log:
[90028.591812] kexec: Applying relocate section .rela.text to 1

I have attached the config.gz from the running 5.1.0 kernel and the
built 5.1.1 kernel. The config was working ok with the 5.0 series.

Thanks
