Subject: [PATCH v2 0/3] selftests/hid: fix building for older kernels
Hi, I am sending this series on behalf of myself and Benjamin Tissoires. There
existed an initial n=3 patch series which was later expanded to n=4 and
is now back to n=3 with some fixes added in and rebased against
mainline.
This patch series aims to ensure that the hid/bpf selftests can be built
without errors.
Here's Benjamin's initial cover letter for context:
| These fixes have been triggered by [0]:
| basically, if you do not recompile the kernel first, and are
| running on an old kernel, vmlinux.h doesn't have the required
| symbols and the compilation fails.
|
| The tests will fail if you run them on that very same machine,
| of course, but the binary should compile.
|
| And while I was sorting out why it was failing, I realized I
| could do a couple of improvements on the Makefile.

Changes from v1 -> v2:
- roll Justin's fix into patch 1/3
- add __attribute__((preserve_access_index)) (thanks Eduard)
- rebased onto mainline (2dde18cd1d8fac735875f2e4987f11817cc0bc2c)

selftests/hid: ensure we can compile the tests on kernels pre-6.3
selftests/hid: do not manually call headers_install
