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
