Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added khdr target to run headers_install target from the main Makefile. The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic.
1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use.
The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build.
e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf
../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop.
There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables.
Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install.
Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined.
Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.

There are already other patches in that branch; a topic branch only includes this one on top of Linus's tree, so that it is independent from other changes being made in both your and my tree.
You should create a new branch in linux-kselftest.git, pull it into next, and tell me the name so that I can pull the same branch into kvm.git.

Looks reasonable to me. Commit 7e0cf1c983b5 ("selftests/powerpc: Fix Makefiles for headers_install change") probably should be redone after this change.
