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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 b45ba4a51cde29b2939365ef0c07ad34c8321789 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_katmai_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/katmai_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_katmai_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:185:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here arch/powerpc/boot/katmai.dtb: Warning (pci_bridge): /plb/pciex@d00000000: node name is not "pci" or "pcie" arch/powerpc/boot/katmai.dtb: Warning (pci_bridge): /plb/pciex@d20000000: node name is not "pci" or "pcie" arch/powerpc/boot/katmai.dtb: Warning (pci_bridge): /plb/pciex@d40000000: node name is not "pci" or "pcie" arch/powerpc/boot/katmai.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x4576c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.19.0-rc3-gb45ba4a51cde2 Created: Wed Oct 3 01:44:49 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2192604 Bytes = 2141.21 KiB = 2.09 MiB Load Address: 00500000 Entry Point: 005010f4 Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_katmai_defconfig_powerpc # Build took: 0:00:15.156588
