This patch is meant to solve the issue reported by lkp in [1] with the KASLR series support for RISC-V. The problem in [1] is caused by the addition of new functions in efi-stub-helper.c which reference symbols that are not defined in the context of zboot. Those functions are not used in zboot but it causes those link errors. I can move those new functions around so that the problem disappears, but I believe that fixing that using the linker garbage collection is more sane. That's an RFC, I'll include it in my KASLR series if that's the right direction.
