I have rebased Jeremy's V2 (which is off-list) onto my new code. The whole series since commit a8de94e: LoongArch: kdump: Set up kernel image segment is available in the Git repository at https://github.com/pfliu/kexec-tools/tree/zboot up to the head I have compiled it on x86_64 and aarch64, and successfully booted the zboot image on aarch64 @Simon, is there any instruction to do the cross-building for kexec-tools, so I can verify the pattern substitution works well on other arches. I think I can post it to the list with a cover-letter after verification.
