The following commit has been merged in the master branch: commit 8f6ab7a2836174f0c73397fbf9eeb5ed5310a6ec Author: Masahiro Yamada <yamada.masahiro(a)socionext.com> Date: Wed Sep 21 09:53:30 2016 +1000 treewide: remove redundant #include <linux/kconfig.h> Kernel source files need not include <linux/kconfig.h> explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

The following commit has been merged in the master branch: commit 2f43d7d9f6368ae79603195c66a465729e46c27f Author: Masahiro Yamada <yamada.masahiro(a)socionext.com> Date: Wed Sep 21 09:53:30 2016 +1000 treewide: remove redundant #include <linux/kconfig.h> Kernel source files need not include <linux/kconfig.h> explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

The following commit has been merged in the master branch: commit 79d26d73739841c6beb8a664e3e040f6d8d36bf6 Author: Masahiro Yamada <yamada.masahiro(a)socionext.com> Date: Wed Sep 21 09:53:30 2016 +1000 treewide: remove redundant #include <linux/kconfig.h> Kernel source files need not include <linux/kconfig.h> explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.
