hours to figure this out and I can easily fix these errors by simply replacing the inclusion that was introduced in our patchset with a forward declaration like this: arch/alpha/lib/memcpy.c | 3 ++- 1

If someone can figure it out please let me know so I can write a meaningful description for the fixup patch.
