Seems like objtool/core has been merged in 5.19. I was able to apply your series on top of powerpc/merge branch. Only a small conflict with patch "objtool: Add --mnop as an option to --mcount" because of commit b42d23065024 ("kbuild: factor out the common objtool arguments") > > Christophe Leroy (3): > objtool: Fix SEGFAULT > objtool: Use target file endianness instead of a compiled constant > objtool: Use target file class size instead of a compiled constant > > Sathvika Vasireddy(9): > objtool: Add --mnop as an option to --mcount > powerpc: Skip objtool from running on VDSO files > objtool: Read special sections with alts only when specific options are selected > objtool: Use macros to define arch specific reloc types > objtool: Add arch specific function arch_ftrace_match() > objtool/powerpc: Enable objtool to be built on ppc > objtool/powerpc: Add --mcount specific implementation > powerpc: Remove unreachable() from WARN_ON() > objtool/powerpc: Fix unannotated intra-function call warnings > > Makefile | 4 +- > arch/powerpc/Kconfig | 2 + > arch/powerpc/include/asm/bug.h | 1 - > arch/powerpc/kernel/entry_64.S | 2 + > arch/powerpc/kernel/exceptions-64s.S | 7 +- > arch/powerpc/kernel/head_64.S | 7 +- > arch/powerpc/kernel/misc_64.S | 4 +- > arch/powerpc/kernel/vdso/Makefile | 2 + > arch/powerpc/kernel/vector.S | 4 +- > arch/powerpc/kvm/book3s_hv_interrupts.S | 4 +- > arch/powerpc/kvm/book3s_hv_rmhandlers.S | 25 +++-- > arch/x86/Kconfig | 1 + > scripts/Makefile.build | 1 + > tools/objtool/arch/powerpc/Build | 2 + > tools/objtool/arch/powerpc/decode.c | 96 +++++++++++++++++++ > .../arch/powerpc/include/arch/cfi_regs.h | 11 +++ > tools/objtool/arch/powerpc/include/arch/elf.h | 10 ++ > .../arch/powerpc/include/arch/special.h | 21 ++++ > tools/objtool/arch/powerpc/special.c | 19 ++++ > tools/objtool/arch/x86/decode.c | 8 ++ > tools/objtool/arch/x86/include/arch/elf.h | 2 + > .../arch/x86/include/arch/endianness.h | 9 -- > tools/objtool/builtin-check.c | 14 +++ > tools/objtool/check.c | 51 +++++----- > tools/objtool/elf.c | 8 +- > tools/objtool/include/objtool/arch.h | 2 + > tools/objtool/include/objtool/builtin.h | 1 + > tools/objtool/include/objtool/elf.h | 8 ++ > tools/objtool/include/objtool/endianness.h | 32 +++---- > tools/objtool/orc_dump.c | 11 ++- > tools/objtool/orc_gen.c | 4 +- > tools/objtool/special.c | 3 +- > 32 files changed, 305 insertions(+), 71 deletions(-) > create mode 100644 tools/objtool/arch/powerpc/Build > create mode 100644 tools/objtool/arch/powerpc/decode.c > create mode 100644 tools/objtool/arch/powerpc/include/arch/cfi_regs.h > create mode 100644 tools/objtool/arch/powerpc/include/arch/elf.h > create mode 100644 tools/objtool/arch/powerpc/include/arch/special.h > create mode 100644 tools/objtool/arch/powerpc/special.c > delete mode 100644 tools/objtool/arch/x86/include/arch/endianness.h >
