Cover letter [PATCH v9 0/7] kexec: put bzImage and ramdisk above 4G for x86 64bit
Now we have limit kdump reserved under 896M, because kexec has the limitation. and also bzImage need to stay under 4g.
kernel parts changes get merged to linus tree already.
here patches are for kexec tools to load bzImage and ramdisk above 4G acccording to new added boot header fields.
it will only load high with 64bit kernel with 2.12 setup header.
-v3: address review from Eric to use locate_hole at first.
use xloadflags instead.
-v4: remove the restriction about bzImage not crossing GB boundary.
add real-mode fix for bzImage.
add --entry-32bit and --real-mode for skip bzImage64.
-v5: use USE_EXT_BOOT_PARAMS bit in xloadflags.
-v6: use sentinel instead of USE_EXT_BOOT_PARAMS.
add crashkernel_low support
-v7: Separate bootloader id setting in another patch -v8: update for CAN_BE_LOADED_ABOVE_4G is changed to bit1.
also make it appliable to current kexec-tools devel tree.
-v9: only copy setup_header when it is not with real_mode_entry.
