Hmm, maybe that just needs to be removed as well, after we
have removed the function declaration that used to follow it
as part of this commit:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9dc5c05f45ca8101025046cd

Using __kernel_size_t would work here as well, but I suspect that
the entire structure is useless as it is not used by kernel or
user space, and kexec_tools has its own copy of the structure.
