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-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6a86fe746e2f69e49328b9ad8ad0f840c467ee59 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_storcenter_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- storcenter_defconfig WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_storcenter_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_storcenter_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_storcenter_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x6116dc) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.11.0-g6a86fe746e2f Created: Tue Feb 23 15:24:14 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2754603 Bytes = 2690.04 KiB = 2.63 MiB Load Address: 00700000 Entry Point: 00700894 Completed OK # rm -rf /kisskb/build/powerpc-fixes_storcenter_defconfig_powerpc-gcc5 # Build took: 0:00:54.633990
