From 0493e5f9058895f851d5b710c1c91970d4ac2bfb Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Wed, 12 Apr 2017 12:43:52 -0700 Subject: UPSTREAM: kbuild: Consolidate header generation from ASM offset information Largely redundant code is used in different places to generate C headers from offset information extracted from assembly language output. Consolidate the code in Makefile.lib and use this instead.
