But in this case GCC is smart enough to notice that "base + # PLB4OPB_GESR0" will be constant, even though it's not something we can # immediately stringify into a register number. # # Segher pointed out that passing the register number to the inline asm # as a constant would be better, and in fact it fixes the build error, # presumably because it gives GCC a chance to resolve the value. # # While we're at it, change mtdcr() similarly. # # Reported-by: kernel test robot <lkp@intel.com> # Suggested-by: Segher Boessenkool <segher@kernel.crashing.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Acked-by: Feng Tang <feng.tang@intel.com> # Link: https://lore.kernel.org/r/20210218123058.748882-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 b12483618d73c954c00faa49c276b4d9995fb95a # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c: In function 'is1_entry_set': /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: missing braces around initializer [-Wmissing-braces] struct ocelot_vcap_u16 etype = {0}; ^ /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: (near initialization for 'etype.value') [-Wmissing-braces] FIT description: Linux 5.11.0-rc2-81081-gb12483618d7 Created: Mon Feb 22 00:48:39 2021 Image 0 (kernel@0) Description: Linux 5.11.0-rc2-81081-gb12483618d7 Created: Mon Feb 22 00:48:39 2021 Type: Kernel Image Compression: gzip compressed Data Size: 5218666 Bytes = 5096.35 KiB = 4.98 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x8098d938 Hash algo: sha1 Hash value: 1296c176522b1971cf28e20eb5c35bc98edf731b Image 1 (fdt@boston) Description: img,boston Device Tree Created: Mon Feb 22 00:48:39 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Mon Feb 22 00:48:39 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Mon Feb 22 00:48:39 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 4659 Bytes = 4.55 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 5bcb6e4f21e8e5372544aa130b3bd097355a9050 Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Mon Feb 22 00:48:39 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 5418 Bytes = 5.29 KiB = 0.01 MiB Architecture: MIPS Hash algo: sha1 Hash value: 93d882f2009a217e0fa9dab94788535ed2be8476 Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Mon Feb 22 00:48:39 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 # Build took: 0:01:38.355032
