# HG changeset patch # User Hollis Blanchard <hollisb@xxxxxxxxxx> # Node ID b58670602d35b2900a19e85c0f79e5aae2b6afdc # Parent 020fc58ba873f300d89cdd3345027d9e81bca3f0 [POWERPC][XEN] Builtin cmdline dependency rule Rebuild cmdline.o when the user changes the CMDLINE=X argument passed to the make invocation.
