Subject: [PATCH 1/1] kbuild: use $(srctree) to locate config headers from external modules
Date: Fri,  1 Aug 2014 15:47:23 -0400	[thread overview]
Message-ID: <1406922443-22770-1-git-send-email-djpohly+linux@gmail.com> (raw)

When making modules_install for an out-of-tree module, the current
directory is $(KBUILD_OUTPUT), and the Makefile recipe which verifies
the existence of files in include/config is unable to find them using a
relative path.  This leads to a spurious and puzzling "Kernel
configuration is invalid" warning when no configuration is actually
needed.

Since the file check is done in a recipe with `test -e' rather than as a
target or include, the usual search paths provided by VPATH and -I are
not consulted, so an explicit path is needed in this case.
