[PATCH v2 0/6] kexec: put bzImage and ramdisk above 4G for x86 64bit

[Yinghai Lu]

Now we have limit kdump reserved 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.

-v2: remove mem64-min/mem64-max
     add purgartory changes from Eric, that make it relocatable
     put command line above 4g.
