From: Masahiro Yamada Date: Mon, 21 Jan 2019 02:48:49 +0000 (+0900) Subject: MIPS: remove meaningless generic-(CONFIG_GENERIC_CSUM) += checksum.h X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a0f0b69f2c15c12eb45b4e8d76f704ba9bc9c126;p=linux.git MIPS: remove meaningless generic-(CONFIG_GENERIC_CSUM) += checksum.h This line is weird in multiple ways. (CONFIG_GENERIC_CSUM) might be a typo of $(CONFIG_GENERIC_CSUM). Even if you add '$' to it, $(CONFIG_GENERIC_CSUM) is never evaluated to 'y' because scripts/Makefile.asm-generic does not include include/config/auto.conf. So, the asm-generic wrapper of checksum.h is never generated. Even if you manage to generate it, it is never included by anyone because MIPS has the checkin header with the same file name: arch/mips/include/asm/checksum.h As you see in the top Makefile, the checkin headers are included before generated ones. LINUXINCLUDE := \ -I$(srctree)/arch/$(SRCARCH)/include \ -I$(objtree)/arch/$(SRCARCH)/include/generated \ ...
