For no actual upside, since # no distro is likely to ever be able to enable it (because they all # support external kernel modules). # # Rather than re-enable EXPORT_UNUSED_SYMBOL, this just disables the # TRIM_UNUSED_KSYMS option by marking it broken. I'm tempted to just # remove the support entirely, but maybe somebody has a use-case and can # fix the behavior of it. # # I could have just disabled it for COMPILE_TEST, but it really smells # like the TRIM_UNUSED_KSYMS option is badly done and not really useful, # so this takes the more direct approach - let's see if anybody ever # actually notices or complains. # # Cc: Miroslav Benes <mbenes@suse.cz> # Cc: Emil Velikov <emil.l.velikov@gmail.com> # Cc: Christoph Hellwig <hch@lst.de> # Cc: Jessica Yu <jeyu@kernel.org> # Fixes: 367948220fce ("module: remove EXPORT_UNUSED_SYMBOL") # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 5cf0fd591f2e7833405bdc7ce2176c3502e8a11e # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- defconfig # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- /kisskb/src/arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': /kisskb/src/arch/m68k/mvme147/config.c:172:2: warning: #warning check me!
