Linus, Please pull the latest objtool/core git tree from: git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git objtool-core-2020-10-13 # HEAD: ab0a40ea88204e1291b56da8128e2845fec8ee88 perf build: Allow nested externs to enable BUILD_BUG() usage objtool changes for v5.10: - Most of the changes are cleanups and reorganization to make the objtool code more arch-agnostic. This is in preparation for non-x86 support. Fixes: - KASAN fixes. - Handle unreachable trap after call to noreturn functions better. - Ignore unreachable fake jumps. - Misc smaller fixes & cleanups.
