Subject: [PATCH] r=nic Anchor the search for the right target to rebuild the
 .config file to avoid using the wrong one just because it's mentioned (as a
 non-target) in the Makefile. If make $oldconfig produces a .config that is
 different than we have for that kernel in the Lustre tree, tell the QA folks
 so they can update the tree to have the same kernel_config.
