Subject: [PATCH v3 12/14] tools/kernel.h: hide noinstr
Date: Mon, 22 Jun 2020 18:42:56 -0400 [thread overview]
Message-ID: <20200622224258.1208588-13-sashal@kernel.org> (raw)
In-Reply-To: <20200622224258.1208588-1-sashal@kernel.org>
After 655389666643 ("vmlinux.lds.h: Create section for protection against
instrumentation") we need to ignore "noinstr" in userspace.
