But it is still created by default on CHRP. # # On powermac the actual map (pci_to_OF_bus_map) is still used by default, # even though the device tree property is not created. # # Add an option to enable/disable use of the pci_to_OF_bus_map, and # creation of the property (on CHRP). # # Disabling the option allows enabling CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT # which allows "normal" bus numbering and more than 256 buses, like 64-bit # and other architectures. # # Mark the new option as default n, the intention is that the option and # the code will be removed in a future release. # # [1]: https://lore.kernel.org/linuxppc-dev/1148016268.13249.14.camel@localhost.localdomain/ # [2]: https://lore.kernel.org/all/575f239205e8635add81c9f902b7d9db7beb83ea.camel@kernel.crashing.org/ # # Signed-off-by: Pali Rohár # [mpe: Reword commit & help text, shrink option name, rework to fix build errors] # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 e870dcd0076521fc3f082b248314c376574ac709 # < make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig # < make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig .config:3652:warning: override: reassigning to symbol DEBUG_INFO_BTF # make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- In function 'setup_lowcore_dat_on', inlined from 'setup_arch' at /kisskb/src/arch/s390/kernel/setup.c:1061:2: /kisskb/src/arch/s390/kernel/setup.c:526:9: warning: 'memcpy' offset [0, 127] is out of the bounds [0, 0] [-Warray-bounds] 526 | memcpy(abs_lc->cregs_save_area, S390_lowcore.cregs_save_area, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 527 | sizeof(abs_lc->cregs_save_area)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 # Build took: 0:04:23.814676
