This provokes early boot failure (before the # console is active). # # As it is not necessary to do this verification that early, this # patch moves the test into patch_instruction() instead of # __patch_instruction(). # # This modification also has the advantage of avoiding unnecessary # remappings. # # Fixes: 51c3c62b58b3 ("powerpc: Avoid code patching freed init sections") # Cc: stable@vger.kernel.org # 4.13+ # Signed-off-by: Christophe Leroy # 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 b45ba4a51cde29b2939365ef0c07ad34c8321789 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- amigaone_defconfig WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] || PPC_8xx [=n] || E200 [=n] || PPC_MPC512x [=n] || GAMECUBE_COMMON [=n] Selected by [y]: - AMIGAONE [=y] && 6xx [=y] && BROKEN_ON_SMP [=y] WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] || PPC_8xx [=n] || E200 [=n] || PPC_MPC512x [=n] || GAMECUBE_COMMON [=n] Selected by [y]: - AMIGAONE [=y] && 6xx [=y] && BROKEN_ON_SMP [=y] WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] || PPC_8xx [=n] || E200 [=n] || PPC_MPC512x [=n] || GAMECUBE_COMMON [=n] Selected by [y]: - AMIGAONE [=y] && 6xx [=y] && BROKEN_ON_SMP [=y] # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x5d7470) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.19.0-rc3+ Created: Wed Oct 3 02:16:47 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2966073 Bytes = 2896.56 KiB = 2.83 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.19.0-rc3+ Created: Wed Oct 3 02:16:47 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2989597 Bytes = 2919.53 KiB = 2.85 MiB Load Address: 00800000 Entry Point: 00800108 Completed OK # rm -rf /kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 # Build took: 0:00:43.803578
