Subject: [PATCH 12/22] x86: Set the SMP flag when MP init is complete
Date: Thu, 21 May 2020 20:23:16 -0600 [thread overview]
Message-ID: <20200522022326.238388-10-sjg@chromium.org> (raw)
In-Reply-To: <20200522022326.238388-1-sjg@chromium.org>
Set this flag so we can track when it is safe to use CPUs other than the
main one.
