Hasn't 32bit dom0 been retired? Untill the kexec firmware pass through and the normal kexec code paths are separated I can't make sense out of this code. The normal kexec code path should be doable without any special constraints on the kernel. Just leaning on some xen paravirt calls. The kexec pass through probably should not even touch x86 arch code. Certainly the same patch should not have code for both the xen kexec pass through and the paravirt arch code for the normal kexec path.
