Now we have limit kdump reseved under 896M, because kexec has the limitation.
and also bzImage need to stay under 4g.
kernel parts changes could be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-boot
here patches are for kexec tools to load bzImage and ramdisk high acccording
to new added boot header fields.
