kbuild: remove --include-dir MAKEFLAG from top Makefile I 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 command tries to build ARM device trees in the separate foo/ directory - this must stop because the directory foo/ has not been configured yet. However, due to --include-dir=$(abs_srctree), the top Makefile includes the wrong include/config/auto.conf from the source tree and continues building. Kbuild traverses the directory tree, but of course it does not 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-dir from the top Makefile. There are more breakages under drivers/, but I do not volunteer to fix them 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 2 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

uml: move sig_handler_common_skas This patch moves sig_handler_common_skas from arch/um/os-Linux/skas/trap.c to its only caller in arch/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 is done in the next patch.
