This series has the steps to remove ELFv1 from the kernel build. Patch 1 is a build fix, 2 defaults everything to ELFv2, 3 is really a separate issue that concerns userspace. 4 removes v1 support.
Would like to try getting patch 1 in as a fix, then 2,3 merged in the next merge window. Thanks, Nick Nicholas Piggin (4): powerpc/64: Force ELFv2 when building with LLVM linker powerpc/64: Make ELFv2 the default for big-endian builds powerpc/64s: Remove support for ELFv1 little endian userspace powerpc/64: Remove support for kernel's built with ELFv1 ABI arch/powerpc/Kconfig | 21 ------ arch/powerpc/Makefile | 15 +---- arch/powerpc/boot/Makefile | 4 +- arch/powerpc/include/asm/code-patching.h | 36 ++-------- arch/powerpc/include/asm/elf.h | 6 ++ arch/powerpc/include/asm/kfence.h | 4 -- arch/powerpc/include/asm/linkage.h | 9 --- arch/powerpc/include/asm/module.h | 3 - arch/powerpc/include/asm/ppc_asm.h | 38 +---------- arch/powerpc/include/asm/ptrace.h | 17 +---- arch/powerpc/include/asm/sections.h | 4 -- arch/powerpc/include/asm/thread_info.h | 6 +- arch/powerpc/kernel/exceptions-64s.S | 2 +- arch/powerpc/kernel/fadump.c | 6 +- arch/powerpc/kernel/head_64.S | 5 +- arch/powerpc/kernel/interrupt_64.S | 4 -- arch/powerpc/kernel/kprobes.c | 39 +---------- arch/powerpc/kernel/misc_64.S | 4 -- arch/powerpc/kernel/module.c | 8 --- arch/powerpc/kernel/module_64.c | 84 ++++-------------------- arch/powerpc/kernel/trace/ftrace.c | 10 --- arch/powerpc/kernel/vdso/Makefile | 2 +- arch/powerpc/kernel/vdso/gettimeofday.S | 2 +- arch/powerpc/kernel/vmlinux.lds.S | 8 --- arch/powerpc/kvm/book3s_hv_rmhandlers.S | 36 +++++----- arch/powerpc/kvm/book3s_interrupts.S | 14 ++-- arch/powerpc/kvm/book3s_rmhandlers.S | 12 +--- arch/powerpc/net/bpf_jit.h | 6 -- arch/powerpc/net/bpf_jit_comp.c | 14 ++-- arch/powerpc/net/bpf_jit_comp64.c | 13 ++-- arch/powerpc/platforms/Kconfig.cputype | 6 -- drivers/crypto/vmx/Makefile | 4 -- kernel/extable.c | 2 +- kernel/trace/ftrace.c | 12 ---- 34 files changed, 79 insertions(+), 377 deletions(-) -- 2.40.1
