Hello all,
This series contains a few minor fixes to the CI config and one
additional patch to common/ that resolve ppc64-specific CI failures
that Jan discovered.
Thanks,

Since ppc64le is still undergoing early bringup, disable the randconfig

raised inside page_alloc.c's node_to_scrub function, likely due to the
