[Xen-devel] [PATCH v4 09/14] x86/tboot: remove paravirt_enabled()

["Luis R. Rodriguez" <mcgrof@xxxxxxxxxx>]

There is already a check for boot_params.tboot_addr prior
to paravirt_enabled(). Both Xen and lguest, which are also the
only ones that set paravirt_enabled to true, never set the
boot_params.tboot_addr. The Xen folks are sure a force disable
to 0 is not needed, we recently forced disabled this on lguest.
With this in place this check is no longer needed.
