Rodriguez" scripts/module-common.lds is currently pretty static, in the future this may change and we will want access to kernel macros to help expands certain areas. To get access to use macros we need to generate module-common.lds from module-common.lds.S, for now though only enable the generation. We'll later expand on this as needed. Since this file is now generated add it to .gitignore. v4: add file to MAINTAINERS v3: new to this series Signed-off-by: Luis R.
