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! :-/

root@spr:/usr/src/linux-2.6# make O=defconfig-build/ -j64
make[1]: Entering directory '/usr/src/linux-2.6/defconfig-build'

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.

@John?
