As per a discussion with Muhammad Usama Anjum [1], the following is how one is supposed to build selftests:
make headers && make -C tools/testing/selftests/mm
Change the selftest build system's lib.mk to fail out with a helpful message if that prerequisite "make headers" has not been done yet.
NAK NAK NAK
This now means I can no longer run selftests, I thank you very much! :-/

I've always done:
cd tools/testing/selftests/x86; make
and that has always worked
Now I can't bloody well build *any* selftest or risk not being able to do builds.
This change landed in 6.5, no? And 6.6 was just released. Just curious why you notice that now.
And I hit it again (different box etc..)
Can we please get this garbage fixed already?
I'd suggest to either revert or turn into a warning.
That would put us back into a half-broken sort of situation, though... see below.
@John?
I don't have a strong opinion about how this should be done, and in fact I believed at the time that I was bringing the system into compliance with what everyone wanted here. :)
There seem to be two conflicting visions:
a) The way it was (much) earlier: use ifdefs and defines to get by without the latest kernel headers, or
b) Requiring recent kernel headers to build the various selftests.
Shuah, Peter, others: can we choose a direction please? Either way will work, and I personally don't care which one we choose.
thanks,
