Subject: [PATCH v3 07/11] x86/tboot: remove paravirt_enabled()
Date: Mon, 22 Feb 2016 23:24:11 -0800 [thread overview]
Message-ID: <1456212255-23959-8-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1456212255-23959-1-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.
