Drop the barrier from # syscall_dotrace, because that syscall number comes from the # kernel.] # 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 a5dde5b54c02a2b1f839939ee89aa69caca3e02c # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc83xx_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: 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/mpc832x_rdb.dtb: Warning (interrupts_property): interrupts size is (4), expected multiple of 8 in /qe@e0100000/mdio@3120/ethernet-phy@0 arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): interrupts size is (4), expected multiple of 8 in /qe@e0100000/mdio@3120/ethernet-phy@4 INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff41c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5eed70) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3023819 Bytes = 2952.95 kB = 2.88 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3023961 Bytes = 2953.09 kB = 2.88 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3023582 Bytes = 2952.72 kB = 2.88 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3024023 Bytes = 2953.15 kB = 2.88 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3000740 Bytes = 2930.41 kB = 2.86 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3023569 Bytes = 2952.70 kB = 2.88 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Sun Apr 1 23:29:26 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3023791 Bytes = 2952.92 kB = 2.88 MB Load Address: 00600000 Entry Point: 00600230 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc # Build took: 0:00:25.208243
