None of the files touched here are modules, and they are not exporting any symbols either -- so there is no need to be including the module.h. Builds of all the files remains successful. Even kernel/module.c does not need to include it, since it includes linux/moduleloader.h instead. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
