Hi Matthew, I am still writing that in-kernel support for kexec/kdump. I guess in next 2 weeks I might be able to post a basic RFC version. (no EFI support in this version though). Having said that, I think that it is good to export these values to user space and make existing code work with UEFI. New code (if it gets in at all) will slowly mature over a period of time and transition to it will be slow. I think initially it will be used only if secureboot is enabled. And in the mean time we need a good solution for kexec/kdump with UEFI. Thanks Vivek
