However the LLVM's # recent change [1] make it equal-or-less than the actual number which # makes it useless. # # This replaces RELACOUNT in zImage loader with a pair of RELASZ and RELAENT. # The vmlinux relocation code is fixed in [2]. # # To make it more future proof, this walks through the entire .rela.dyn # section instead of assuming that the section is sorter by a relocation # type. Unlike [1], this does not add unaligned UADDR/UADDR64 relocations # as in hardly possible to see those in arch-specific zImage. # # [1] https://github.com/llvm/llvm-project/commit/da0e5b885b25cf4 # [2] https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?h=next&id=d799769188529a # # Signed-off-by: Alexey Kardashevskiy # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20220321071026.918262-1-aik@ozlabs.ru # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9fa62ccf07a78e8ca3d8a3ce59276f4ef6660e58 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4324:warning: override: reassigning to symbol PPC_E500MC .config:4325:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/bitops.h:33, from /kisskb/src/include/linux/kernel.h:22, from /kisskb/src/include/linux/cpumask.h:10, from /kisskb/src/include/linux/smp.h:13, from /kisskb/src/include/linux/lockdep.h:14, from /kisskb/src/include/linux/mutex.h:17, from /kisskb/src/arch/powerpc/include/asm/kvm_ppc.h:15, from /kisskb/src/arch/powerpc/kvm/e500_emulate.c:12: /kisskb/src/arch/powerpc/include/asm/bitops.h: In function 'kvmppc_core_emulate_op_e500': /kisskb/src/arch/powerpc/include/asm/bitops.h:104:3: error: asm operand 2 probably doesn't match constraints [-Werror] 104 | asm volatile ( \ | ^~~ /kisskb/src/arch/powerpc/include/asm/bitops.h:126:1: note: in expansion of macro 'DEFINE_CLROP' 126 | DEFINE_CLROP(clear_bits, "") | ^~~~~~~~~~~~ /kisskb/src/arch/powerpc/include/asm/bitops.h:104:3: error: impossible constraint in 'asm' 104 | asm volatile ( \ | ^~~ /kisskb/src/arch/powerpc/include/asm/bitops.h:126:1: note: in expansion of macro 'DEFINE_CLROP' 126 | DEFINE_CLROP(clear_bits, "") | ^~~~~~~~~~~~ cc1: all warnings being treated as errors make[3]: *** [/kisskb/src/scripts/Makefile.build:288: arch/powerpc/kvm/e500_emulate.o] Error 1 make[2]: *** [/kisskb/src/scripts/Makefile.build:550: arch/powerpc/kvm] Error 2 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/kisskb/src/Makefile:1831: arch/powerpc] Error 2 make[1]: *** Waiting for unfinished jobs....
