This adds a test to detect the bug. # # Signed-off-by: Sandipan Das # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/af137a935684955a60f13de2eb4ca358284f3d7c.1594897099.git.sandipan@linux.ibm.com # < /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 78807804b0854ecb7dc6906e379fc688aca36456 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc44x_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b95a4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2930987 Bytes = 2862.29 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 006001b8 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931574 Bytes = 2862.87 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 00601534 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931632 Bytes = 2862.92 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 00601524 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931751 Bytes = 2863.04 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 006000c4 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931695 Bytes = 2862.98 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 00601534 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931754 Bytes = 2863.04 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 00601534 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931797 Bytes = 2863.08 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 00601514 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931814 Bytes = 2863.10 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 0060152c Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 02:36:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2931676 Bytes = 2862.96 KiB = 2.80 MiB Load Address: 00600000 Entry Point: 00601544 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc5 # Build took: 0:01:13.379773
