memblock.c:(.text+0x7171): undefined reference to `mirrored_kernelcore'

"fix compilation errors" looks better, don't you think?

Another thing, is when you post vN of a patch please add a "patch
changelog" that describes the changes to the previous version.

I'd suggest to take a look at sections "Respond to review comments" and
"Don't get discouraged - or impatient" of the submitting patches guide.

As people pointed in v1 thread, the description on how to reproduce this is
missing.
