kbuild: Fix removal of the debian/ directory

2015-01-27T16:29:45Z

commit a16c5f99a28c9945165c46da27fff8e6f26f8736 upstream. scripts/Makefile.clean treats absolute path specially, but $(objtree)/debian is no longer an absolute path since 7e1c0477 (kbuild: Use relative path for $(objtree). Work around this by checking if the path starts with $(objtree)/.

kbuild: simplify build, clean, modbuiltin shorthands

2014-10-02T13:12:41Z

$(if $(KBUILD_SRC),$(srctree)/) was a useful strategy to omit a long absolute path for in-source-tree build prior to commit 890676c65d699db3ad82e7dddd0cf8fb449031af (kbuild: Use relative path when building in the source tree). Now $(srctree) is "." when building in the source tree. It would not be annoying to add "$(srctree)/" all the time. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

kbuild: remove obj-n and lib-n handling

2014-10-02T11:55:02Z

Kconfig never defines CONFIG_* as 'n'. Now obj-n is only used in firmware/Makefile and it can be replaced with obj-. No makefile uses lib-n. Let's rip off obj-n and lib-n. Signed-off-by: Masahiro Yamada Acked-by: Peter Foley Signed-off-by: Michal Marek

kbuild: Really don't clean bounds.h and asm-offsets.h

2010-03-11T10:15:22Z

Commit 7d3cc8b tried to keep bounds.h and asm-offsets.h during make clean by filtering these out of $(clean-files), but they are listed in $(targets) and $(always) and thus removed automatically. Introduce a new $(no-clean-files) variable to really skip such files in Makefile.clean. Signed-off-by: Michal Marek

kbuild: kill backward compatibility checks

2007-10-12T19:20:32Z

These checks has been present for several kernel releases (> 5). So lets just get rid of them. With this we no longer check for use of: EXTRA_TARGETS, O_TARGET, L_TARGET, list-multi, export-objs There were three remaining in-tree users of O_TARGET in some unmaintained sh64 code - mail sent to the maintainer + list.

kbuild: change kbuild to not rely on incorrect GNU make behavior

2006-03-05T23:09:51Z

The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

kbuild: fix building external modules

2005-07-27T20:11:01Z

kbuild failed to locate Makefile for external modules. This brought to my attention how the variables for directories have different values in different usage scenarios. Different kbuild usage scenarios: make - plain make in same directory where kernel source lives make O= - kbuild is told to store output files in another directory make M= - building an external module make O= M= - building an external module with kernel output seperate from src Value assigned to the different variables: |$(src) |$(obj) |$(srctree) |$(objtree) make |reldir to k src |as src |abs path to k src |abs path to k src make O= |reldir to k src |as src |abs path to k src |abs path to output dir make M= |abs path to src |as src |abs path to k src |abs path to k src make O= M= |abs path to src |as src |abs path to k src |abs path to k output path to kbuild file: make | $(srctree)/$(src), $(src) make O= | $(srctree)/$(src) make M= | $(src) make O= M= | $(src) From the table above it can be seen that the only good way to find the home directory of the kbuild file is to locate the one of the two variants that is an absolute path. If $(src) is an absolute path (starts with /) then use it, otherwise prefix $(src) with $(srctree). Signed-off-by: Sam Ravnborg

kbuild: define clean before including kbuild file

2005-07-25T22:41:12Z

Defining clean before including the kbuild file give us knowledge when the kbuild file is included for cleaning. This is rarey usefull - but in a corner case in klibc this proved necessary. Signed-off-by: Sam Ravnborg ---
