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-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 78807804b0854ecb7dc6906e379fc688aca36456 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc44x_defconfig # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x66f454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3177860 Bytes = 3103.38 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701630 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3178425 Bytes = 3103.93 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701620 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3177970 Bytes = 3103.49 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701640 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3177554 Bytes = 3103.08 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701640 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3178389 Bytes = 3103.90 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701640 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3178315 Bytes = 3103.82 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 007000bc Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3178304 Bytes = 3103.81 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701640 Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3177586 Bytes = 3103.11 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 007001bc Image Name: Linux-5.8.0-rc2-g78807804b085 Created: Mon Jul 27 03:53:28 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3177900 Bytes = 3103.42 KiB = 3.03 MiB Load Address: 00700000 Entry Point: 00701650 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc44x_defconfig_powerpc-gcc9 # Build took: 0:01:13.128717
