[PATCH 01/34] selftests: arm64: Fix incorrect kernel headers search path

[Mathieu Desnoyers]

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).

(It might be useful to add a "Fixes" tag as well to clearly indicate the
dependence with a specific commit and better understand the fix.)

(and add all the individual maintainers of the files you modify -- feel
free to use 'b4' to help you for this task ;-) )

I only looked at the modification here with MPTCP selftests and it looks
good to me. It makes sense because if KHDR_INCLUDES is not set, it will
be set later by lib.mk I suppose.

Just one small thing: I guess you can also remove "top_srcdir" variable
that is no longer used, right? I see that "lib.mk" uses a variable with
the same name but it overrides its value anyway. But it is likely I
missed something there :)

If indeed it is no longer needed, I guess a few Makefile can be adapted
according to:

  git grep top_srcdir -- tools/testing/selftests/*/

I guess most of these Makefile are very similar, no? For MPTCP, we
simply looked at what was done elsewhere :)

Cheers,
Matt

Just a bit of context: I found this problematic pattern in my own 
selftests (rseq and membarrier), and figured that it was an issue all 
across the board. I did an initial single-patch fix, and then split it 
up in 34 patches based on feedback from Shuah Khan.

I know it should have a Fixed ... tag, but I simply don't have time to 
do the historical investigation work for all the 34 patches form this 
patchset. Perhaps someone else is up to the task ?

If this can be automated, then perhaps Shuah can use it to append the 
relevant information ?

Yes, this should perhaps come as additional fixes on top of my series. I 
don't have time to do it myself though.

Anyone willing to contribute it ?

Yes, I did likewise.
