Subject: [PATCH 6/9] x86/tboot: remove paravirt_enabled()
Date: Fri, 19 Feb 2016 05:08:33 -0800	[thread overview]
Message-ID: <1455887316-9223-7-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1455887316-9223-1-git-send-email-mcgrof@kernel.org>

There is already a check for boot_params.tboot_addr prior
to paravirt_enabled() and both Xen and lguest never set this.
This check is not needed.
