Subject: [PATCH v5 4/5] x86/tboot: Fail extended mode reduced hardware sleep
Date: Fri, 28 Jun 2013 09:46:23 -0400	[thread overview]
Message-ID: <1372427184-6197-5-git-send-email-benjamin.guthro@citrix.com> (raw)
In-Reply-To: <1372427184-6197-1-git-send-email-benjamin.guthro@citrix.com>

As tboot currently does not support the reduced hardware sleep
interface, fail this extended call.
