Note: There are conflicts in arch/loongarch/Kconfig and arch/loongarch/ Makefile but can be simply fixed by adjusting context. ---------------------------------------------------------------- Huacai Chen (5): LoongArch: Select ARCH_HAS_CURRENT_STACK_POINTER in Kconfig LoongArch: Select HAVE_ARCH_USERFAULTFD_MINOR in Kconfig LoongArch: Change __my_cpu_offset definition to avoid mis-optimization LoongArch: Remove superfluous flush_dcache_page() definition LoongArch: Define the __io_aw() hook as mmiowb() Jinyang He (1): LoongArch: Add kernel livepatching support Max Kellermann (1): LoongArch: Move {dmw,tlb}_virt_to_page() definition to page.h Tiezhu Yang (7): objtool/LoongArch: Enable objtool to be built objtool/LoongArch: Implement instruction decoder objtool/x86: Separate arch-specific and generic parts objtool/LoongArch: Enable orc to be built objtool: Check local label in add_dead_ends() objtool: Check local label in read_unwind_hints() LoongArch: Add ORC stack unwinder support Yuli Wang (1): LoongArch/crypto: Clean up useless assignment operations arch/loongarch/Kconfig | 8 + arch/loongarch/Kconfig.debug | 11 + arch/loongarch/Makefile | 23 +- arch/loongarch/crypto/crc32-loongarch.c | 2 - arch/loongarch/include/asm/Kbuild | 3 + arch/loongarch/include/asm/bug.h | 1 + arch/loongarch/include/asm/cacheflush.h | 3 - arch/loongarch/include/asm/exception.h | 2 + arch/loongarch/include/asm/io.h | 2 + arch/loongarch/include/asm/module.h | 7 + arch/loongarch/include/asm/orc_header.h | 18 + arch/loongarch/include/asm/orc_lookup.h | 31 ++ arch/loongarch/include/asm/orc_types.h | 58 +++ arch/loongarch/include/asm/page.h | 3 + arch/loongarch/include/asm/percpu.h | 7 +- arch/loongarch/include/asm/pgtable.h | 3 - arch/loongarch/include/asm/qspinlock.h | 18 - arch/loongarch/include/asm/stackframe.h | 3 + arch/loongarch/include/asm/thread_info.h | 2 + arch/loongarch/include/asm/unwind.h | 20 +- arch/loongarch/include/asm/unwind_hints.h | 28 ++ arch/loongarch/kernel/Makefile | 4 + arch/loongarch/kernel/entry.S | 5 + arch/loongarch/kernel/fpu.S | 7 + arch/loongarch/kernel/genex.S | 6 + arch/loongarch/kernel/lbt.S | 3 + arch/loongarch/kernel/mcount_dyn.S | 6 + arch/loongarch/kernel/module.c | 22 +- arch/loongarch/kernel/relocate_kernel.S | 7 +- arch/loongarch/kernel/rethook_trampoline.S | 1 + arch/loongarch/kernel/setup.c | 2 + arch/loongarch/kernel/stacktrace.c | 41 ++ arch/loongarch/kernel/traps.c | 42 +- arch/loongarch/kernel/unwind_orc.c | 528 +++++++++++++++++++++ arch/loongarch/kernel/vmlinux.lds.S | 3 + arch/loongarch/kvm/switch.S | 9 +- arch/loongarch/lib/clear_user.S | 3 + arch/loongarch/lib/copy_user.S | 3 + arch/loongarch/lib/memcpy.S | 3 + arch/loongarch/lib/memset.S | 3 + arch/loongarch/mm/tlb.c | 27 +- arch/loongarch/mm/tlbex.S | 9 + arch/loongarch/vdso/Makefile | 1 + include/linux/compiler.h | 9 + scripts/Makefile | 7 +- tools/arch/loongarch/include/asm/inst.h | 161 +++++++ tools/arch/loongarch/include/asm/orc_types.h | 58 +++ tools/include/linux/bitops.h | 11 + tools/objtool/Makefile | 4 + tools/objtool/arch/loongarch/Build | 3 + tools/objtool/arch/loongarch/decode.c | 356 ++++++++++++++ .../objtool/arch/loongarch/include/arch/cfi_regs.h | 22 + tools/objtool/arch/loongarch/include/arch/elf.h | 30 ++ .../objtool/arch/loongarch/include/arch/special.h | 33 ++ tools/objtool/arch/loongarch/orc.c | 171 +++++++ tools/objtool/arch/loongarch/special.c | 15 + tools/objtool/arch/x86/Build | 1 + tools/objtool/arch/x86/orc.c | 188 ++++++++ tools/objtool/check.c | 52 +- tools/objtool/include/objtool/elf.h | 1 + tools/objtool/include/objtool/orc.h | 14 + tools/objtool/orc_dump.c | 69 +-- tools/objtool/orc_gen.c | 113 +---- 63 files changed, 2040 insertions(+), 266 deletions(-) create mode 100644 arch/loongarch/include/asm/orc_header.h create mode 100644 arch/loongarch/include/asm/orc_lookup.h create mode 100644 arch/loongarch/include/asm/orc_types.h delete mode 100644 arch/loongarch/include/asm/qspinlock.h create mode 100644 arch/loongarch/include/asm/unwind_hints.h create mode 100644 arch/loongarch/kernel/unwind_orc.c create mode 100644 tools/arch/loongarch/include/asm/inst.h create mode 100644 tools/arch/loongarch/include/asm/orc_types.h create mode 100644 tools/objtool/arch/loongarch/Build create mode 100644 tools/objtool/arch/loongarch/decode.c create mode 100644 tools/objtool/arch/loongarch/include/arch/cfi_regs.h create mode 100644 tools/objtool/arch/loongarch/include/arch/elf.h create mode 100644 tools/objtool/arch/loongarch/include/arch/special.h create mode 100644 tools/objtool/arch/loongarch/orc.c create mode 100644 tools/objtool/arch/loongarch/special.c create mode 100644 tools/objtool/arch/x86/orc.c create mode 100644 tools/objtool/include/objtool/orc.h
