Subject: [PATCH v2 23/25] objtool: Add HAVE_NOINSTR_VALIDATION
Date: Mon, 18 Apr 2022 09:50:42 -0700	[thread overview]
Message-ID: <488e94f69db4df154499bc098573d90e5db1c826.1650300597.git.jpoimboe@redhat.com> (raw)
In-Reply-To: <cover.1650300597.git.jpoimboe@redhat.com>

Remove CONFIG_NOINSTR_VALIDATION's dependency on HAVE_OBJTOOL, since
other arches might want to implement objtool without it.
