Date: Thu, 17 Apr 2014 10:11:47 -0400 From: Peter Foley <pefoley2@...oley.com> To: linux-kernel@...r.kernel.org Cc: rdunlap@...radead.org, linux-doc@...r.kernel.org, Peter Foley <pefoley2@...oley.com> Subject: [PATCH 1/4] Documentation: use subdir-y to avoid unnecessary built-in.o files Change the Documentation makefiles from obj-m to subdir-y to avoid generating unnecessary built-in.o files since nothing in Documentation/ is ever linked in to vmlinux.
