After a lot of trial and error to get them right, these fragments have always
worked for me:
make defconfig ARCH=x86_64
./scripts/kconfig/merge_config.sh .config ../run_qemu/.github/workflows/*.cfg
Warning: there is a CONFIG_DRM=n in there to save a lot of compilation
time. Nothing against DRM specifically; it's just the best "value" for
a single line change :-)
The run_qemu/.github/workflows/*.cfg fragments are mostly duplicated
from ndctl.git/README.md - but unlike the latter, they're
machine-readable and testable. The CXL fragment is actually tested in
run_qemu's CI (CI = the only way not to bitrot).

As I wrote in
https://lore.kernel.org/linux-cxl/aed71134-1029-4b88-ab20-8dfa527a7...@linux.intel.com/
these fragments should ideally live in ndctl.git/, not in run_qemu.git/
(the latter could still add tweaks). Then ndctl.git/README.md could just
refer to the testable fragments instead of inlining them. "Send patches"
they say :-)
