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.

-v3: address review from Eric to use locate_hole at first.
     use xloadflags instead.

Yinghai Lu (4):
  kexec, x86: add boot header member for version 2.12
  kexec, x86: put ramdisk high for 64bit bzImage
  kexec, x86: set ext_cmd_line_ptr when boot_param is above 4g
  kexec, x86_64: Load bzImage64 above 4G
