Subject[PATCH 08/19] Kbuild, lto, workaround: Don't warn for initcall_reference in modpost
Date
From: Andi Kleen <ak@linux.intel.com>

This reference is discarded, but can cause warnings when it refers to
exit. Ignore for now.

This is a workaround and can be removed once we get rid of
-fno-toplevel-reorder
