On Xen, we have to use /proc/iomem to retrieve the memory area for the kexec'd
kernel, not /sys/firmware/memmap. Dom0 kernel gets a E820 map that contains
only one region:
-18e5e000 (System RAM)
Compared to the /proc/iomem:
-0009cbff : System RAM
Fix a bug of kexec load on x86_64. Kexec fails to do load on x86_64, with
error message:
Symbol: cmdline_end not found cannot set
Because kexec/arch/i386/kexec-bzImage.c accesses cmdline_end symbol in
i386 purgatory, but there is no cmdline_end in x86_64 purgatory, and
kexec-bzImage.c is used

This isn't kernel code? Where is /purgatory/ ?
Anyway, for kernel code, that should be:
char *cmdline_end = NULL;
This patch is against kexec tools, not kernel.
