Will tune the changelog > after I confirming it. kexec on arm will have same problem when there's no external dtb being passed. But kexec kernel failed to start up during my test there may be other problems. I will work out a new patch for new option about skip adding root= from 1st kernel. BTW, there's also a problem with external dtb --dtb option, I sent a patch to revert the mmap patch from Michael, please review. Thanks Dave
