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/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-gcc --version # < git log --format=%s --max-count=1 b45ba4a51cde29b2939365ef0c07ad34c8321789 # < make -s -j 120 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- mmu_defconfig # make -s -j 120 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ Kernel: arch/microblaze/boot/linux.bin is ready (#1) Completed OK # rm -rf /kisskb/build/powerpc-fixes_mmu_defconfig_microblaze # Build took: 0:00:22.508978
