Hi, Here is the update patches for adding a new option --dt-no-old-root. Per previously discussion with Simon, we should consider the compatibility issue for changing the old behavior. Thus a new option is necessary The 1st patch move the copying code to another function. The other two patches are for adding arch dependent option for arm and ppc64. Tested kexec load on both arm and ppc64 machines. For the latter two patches, some usage lines are over 80 characters, but I just keep same with original formats. I prefer to fix it in other patches. If you think it really need being fixed in this patchset please let me know, I can update them again. Thanks Dave
