[PATCH v2 06/28] objtool: Don't autodetect vmlinux.o
From: Sami Tolvanen <samitolvanen@google.com>

linux-arch, linux-kbuild, linux-pci, lkml
Subsystem:
kernel build + files below scripts/ (unless maintained elsewhere), objtool, the rest · Maintainers:
Nathan Chancellor, Nicolas Schier, Josh Poimboeuf, Peter Zijlstra, Linus Torvalds
With LTO, we run objtool on vmlinux.o, but don't want noinstr validation. This change requires --vmlinux to be passed to objtool explicitly.
