Subject: Does kexec/kdump support 32bit user App with 64 bit kernel?

Hi experts,

For kexec and kdump, I have a question about 32/64 bits. In such an environment
that 64 bits kernel with 32bit kexec-tools. Can the kdump works in order?

>From code review, the 32bit kexec-tools wil make a 32bit ELF header while the
64bits dump-kernel will check the very ELF header and then deny it for this
reason. Does this is designed? Or can it be resolved/workaround?

Thanks a lot
Xiao
