Kernel-doc has an obscure logic that uses an external file
to map files via a .tmp_filelist.txt file stored at the current
directory. The rationale for such code predates git time,
as it was added on Kernel v2.4.5.5, with the following description:
# 26/05/2001 - Support for separate source and object trees.
# Return error code.
# Keith Owens <kaos@xxxxxxxxxx>
from commit 396a6123577d ("v2.4.5.4 -> v2.4.5.5") at the historic
tree:
https://git.kernel.org/pub/scm/linux/kernel/git/history/history.git/
Support for separate source and object trees is now done on a different
way via make O=<object>.
There's no logic to create such file, so it sounds to me that this is
just dead code.
So, drop it.
