Subject: [PATCH v5 07/14] tools/lguest: force disable tboot and apm
Date: Fri, 8 Apr 2016 16:40:18 -0700 [thread overview]
Message-ID: <1460158825-13117-8-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1460158825-13117-1-git-send-email-mcgrof@kernel.org>
The paravirt_enabled() check is going away, the area tossed to
the kernel on lguest is not zerored out, so ensure lguest force
disables tboot and apm just in case the kernel file being read might
have this set for whatever reason.
