That will then always trigger the # "start >= extent_end" test, which will end up never falling through to # the use of that variable. # # But the code is certainly not obvious, and the compiler warning looks # reasonable. Make 'extent_type' an int, and initialize it to an invalid # negative value, which seems to be the common pattern in other places. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 7e74e235bb31a1fefc28d5303da0718b88627ea8 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus-rand_randconfig+ppc64le_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x93237646 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=n # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_BOOK3E_64=n # Added to kconfig CONFIG_PPC_BOOK3S_64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # yes \n \| make -s -j 120 ARCH=powerpc O=/kisskb/build/linus-rand_randconfig+ppc64le_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus-rand_randconfig+ppc64le_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/arch/powerpc/xmon/xmon.c:67:0: /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_powerpc': /kisskb/src/arch/powerpc/xmon/dis-asm.h:20:9: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ^ /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_spu': /kisskb/src/arch/powerpc/xmon/dis-asm.h:26:9: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ^ /kisskb/src/arch/powerpc/kernel/eeh.c:1792:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] static int proc_eeh_show(struct seq_file m, void v) ^ /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c: In function 'soc15_set_ip_blocks': /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c:613:3: warning: #warning "Enable CONFIG_DRM_AMD_DC for display support on SOC15."
