Adding this as a new file is fine for me.

There were proposed changes to this function this kernel cycle
(CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC) which I Acked already.
However it looks like all involved with that are already particpating
in this thread so I assume an merge issues with that are already in
hand.

Aaron: Are you OK to add the new kdb file to the "KGDB / KDB
/debug_core" file list in MAINTAINERS? Mostly I'd expect to just
Ack changes and move on... but I'd like to be in the loop.
