kbuild: collect shorthands into scripts/Kbuild.include

2018-12-21T13:20:41+00:00

The shorthand "clean" is defined in both the top Makefile and scripts/Makefile.clean. Likewise, the "hdr-inst" is defined in both the top Makefile and scripts/Makefile.headersinst. To reduce code duplication, this commit collects them into scripts/Kbuild.include like the "build" and "modbuiltin" shorthands. It requires scripts/Makefile.clean to include scripts/Kbuild.include, but its impact on the performance of "make clean" should be negligible.

kbuild: use $(Q) for sub-make target

2018-11-29T15:57:58+00:00

Since commit 066b7ed9558087a7957a1128f27d7a3462ff117f (kbuild: Do not print the build directory with make -s), "Q" is defined above the sub-make target. This commit takes advantage of that and replaces "$(if $(KBUILD_VERBOSE:1=),@)" with "$(Q)". Signed-off-by: Masahiro Yamada Acked-by: Peter Foley Signed-off-by: Michal Marek

kbuild: fake the "Entering directory ..." message more simply

2018-11-29T15:57:58+00:00

Commit c2e28dc975ea87feed84415006ae143424912ac7 (kbuild: Print the name of the build directory) added a gimmick to show the "Entering directory ...". Instead of echoing the hard-coded message (that is, we need to know the exact message), moving --no-print-directory would be easier.

kbuild: simplify build, clean, modbuiltin shorthands

2018-11-29T15:57:58+00:00

$(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: Fix make help- on powerpc

2018-11-29T15:57:57+00:00

make ARCH=powerpc help- should not require a cofigured source tree. Also, sort the boards in the output. Signed-off-by: Michal Marek

kbuild: forbid kernel directory to contain spaces and colons

2018-11-29T15:57:57+00:00

When the kernel path contains a space or a colon somewhere in the path name, the modules_install target doesn't work anymore, as the path names are not enclosed in double quotes. It is also supposed that and O= build will suffer from the same weakness as modules_install. Instead of checking and improving kbuild to resist to directories including these characters, error out early to prevent any build if the kernel's main directory contains a space.

kbuild: Allow arch Makefiles to override {cpp,ld,c}flags

2018-11-29T15:57:57+00:00

Since commit a1c48bb1 (Makefile: Fix unrecognized cross-compiler command line options), the arch Makefile is included earlier by the main Makefile, preventing the arc architecture to set its -O3 compiler option. Since there might be more use cases for an arch Makefile to fine-tune the options, add support for ARCH_CPPFLAGS, ARCH_AFLAGS and ARCH_CFLAGS variables that are appended to the respective kbuild variables. The user still has the final say via the KCPPFLAGS, KAFLAGS and KCFLAGS variables. Reported-by: Vineet Gupta Cc: stable@vger.kernel.org # 3.16+ Signed-off-by: Michal Marek

kbuild: Automatically remove stale file

2018-11-29T15:57:57+00:00

In 3.7, the file moved from include/linux/ to include/generated/uapi/linux/. The path in the #include directive remained the same for compatibility reasons, but this created a problem when bisecting. Commit 9c8cdb71 (kbuild: unconditionally clobber include/linux/version.h on distclean) fixes this, provided the user does make distclean between builds. Better not rely on the user and delete the stale file each time make is invoked. Cc: Paul Gortmaker Cc: David Howells Signed-off-by: Michal Marek
