Hello Liu, I'm curious how you tested this? The crash utility does not have any specific support for LPAE on ARM, and a couple years ago I asked on the crash-utility mailing list whether any of the ARM developers were working on it. But at that time none of them were working with LPAE. I see that you are on the crash-utility mailing list -- are you planning to post follow-up patches to the crash-utility? Thanks, Dave

I can't speak for the linux-arm and kexec mailing lists, but certainly when you post your crash-related patches on the crash-utility mailing list, I'll review, respond, and get them in place as soon as possible.
