There are a lot of places in the kernel which iterate through an EFI memory map. Most of these places use essentially the same for-loop code. This patch adds a for_each_efi_memory_desc() helper to clean up all of the existing duplicate code and avoid more in the future.

I just picked up your previous patch ("x86/efi: Create memory map iteration helper") which adds this chunk, and I didn't see a follow up email telling me not to pick it up. What's the plan?
Sorry, I meant to drop this one from this series. The one you picked up is the one I wanted picked up. --Mark
