Subject: [PATCH v3 05/11] tools/lguest: force disable tboot and apm
Date: Mon, 22 Feb 2016 23:24:09 -0800 [thread overview]
Message-ID: <1456212255-23959-6-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1456212255-23959-1-git-send-email-mcgrof@kernel.org>
The paravirt_enabled() check is going away, force disable
tboot and apm just in case the kernel file being read might
have this set for whatever reason.
Signed-off-by: Luis R. Rodriguez <mcgrof@kernel.org>
