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/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6a86fe746e2f69e49328b9ad8ad0f840c467ee59 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc834x_itx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/mpc834x_itx_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc834x_itx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc834x_itx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc834x_itx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1314:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ INFO: Uncompressed kernel (size 0x71b3a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x71b3a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x70ad90) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) Image Name: Linux-5.11.0-g6a86fe746e2f Created: Tue Feb 23 16:57:24 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3230760 Bytes = 3155.04 KiB = 3.08 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.11.0-g6a86fe746e2f Created: Tue Feb 23 16:57:24 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3260445 Bytes = 3184.03 KiB = 3.11 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-g6a86fe746e2f Created: Tue Feb 23 16:57:24 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3260914 Bytes = 3184.49 KiB = 3.11 MiB Load Address: 00800000 Entry Point: 00800294 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_mpc834x_itx_defconfig_powerpc-gcc4.9 # Build took: 0:01:03.966398
