67d7c302 - kbuild: remove --include-dir MAKEFLAG from top Makefile

Sat, 28 Jan 2023 09:24:23 +0000

kbuild: remove --include-dir MAKEFLAG from top MakefileI added $(srctree)/ to some included Makefiles in the following commits: - 3204a7fb98a3 ("kbuild: prefix $(srctree)/ to some included Makefiles") - d82856395505 ("kbuild: do not require sub-make for separate output tree builds")They were a preparation for removing --include-dir flag.I have never thought --include-dir useful. Rather, it _is_ harmful.For example, run the following commands: $ make -s ARCH=x86 mrproper defconfig $ make ARCH=arm O=foo dtbs make[1]: Entering directory '/tmp/linux/foo' HOSTCC scripts/basic/fixdep Error: kernelrelease not valid - run 'make prepare' to update it UPD include/config/kernel.release make[1]: Leaving directory '/tmp/linux/foo'The first command configures the source tree for x86. The next commandtries to build ARM device trees in the separate foo/ directory - thismust stop because the directory foo/ has not been configured yet.However, due to --include-dir=$(abs_srctree), the top Makefile includesthe wrong include/config/auto.conf from the source tree and continuesbuilding. Kbuild traverses the directory tree, but of course it doesnot work correctly. The Error message is also pointless - 'make prepare'does not help at all for fixing the issue.This commit fixes more arch Makefile, and finally removes --include-dirfrom the top Makefile.There are more breakages under drivers/, but I do not volunteer to fixthem all. I just moved --include-dir to drivers/Makefile.With this commit, the second command will stop with a sensible message. $ make -s ARCH=x86 mrproper defconfig $ make ARCH=arm O=foo dtbs make[1]: Entering directory '/tmp/linux/foo' SYNC include/config/auto.conf.cmd *** *** The source tree is not clean, please run 'make ARCH=arm mrproper' *** in /tmp/linux *** make[2]: *** [../Makefile:646: outputmakefile] Error 1 /tmp/linux/Makefile:770: include/config/auto.conf.cmd: No such file or directory make[1]: *** [/tmp/linux/Makefile:793: include/config/auto.conf.cmd] Error 2 make[1]: Leaving directory '/tmp/linux/foo' make: *** [Makefile:226: __sub-make] Error 2Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/um/os-Linux/skas/Makefile

75ada8ff - uml: move sig_handler_common_skas

Tue, 05 Feb 2008 06:31:12 +0000

uml: move sig_handler_common_skasThis patch moves sig_handler_common_skas fromarch/um/os-Linux/skas/trap.c to its only caller inarch/um/os-Linux/signal.c. trap.c is now empty, so it can be removed.This is code movement only - the significant cleanup needed here isdone in the next patch.Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/um/os-Linux/skas/Makefile
