It does fail but not in the # right way. That is it SEGVs trying to load from the opd at BAD_NIP, # but it never gets as far as branching to BAD_NIP. # # To fix it we need to create an opd which is reachable but which holds # the bad address. # # Fixes: b7683fc66eba ("selftests/powerpc: Add a test of wild bctr") # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 2c7645b0f7d1014f2636393de7906c6bfd25939f # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_tqm8560_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/tqm8560_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_tqm8560_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x4e6bd4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4d64e8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.20.0-rc1-g2c7645b0f7d1 Created: Tue Nov 13 20:28:47 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2512217 Bytes = 2453.34 KiB = 2.40 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.20.0-rc1-g2c7645b0f7d1 Created: Tue Nov 13 20:28:47 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2543231 Bytes = 2483.62 KiB = 2.43 MiB Load Address: 00500000 Entry Point: 00500320 Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_tqm8560_defconfig_powerpc-gcc5 # Build took: 0:00:37.021434
