Yes, you are very "sensitive"! our team has worked on it for a while. And
we went through the whole kdump process for LPAE enabled ARM. Our changes
include kexec-tools, makedumpfile, crash utility and the kernel.

But we did that in a rather limited time. So some patches are silly and
need to be reconstructed before submission. In addition, my job is quit
full now. So I decide to post the patch series that are clear and
independent of the others at first.

But I got no response from the linux-arm and kexec mailinglist. What about
your opinion about the feature of LPAE support for kdump related tools
including crash utility and the kernel?

Thanks,
Liu Hua
