Subject: [PATCH 06/10] x86/paravirt: introduce new config option PARAVIRT_XXL
Date:   Fri, 10 Aug 2018 13:52:48 +0200
Message-Id: <20180810115252.18213-7-jgross@suse.com>
In-Reply-To: <20180810115252.18213-1-jgross@suse.com>
References: <20180810115252.18213-1-jgross@suse.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A large amount of paravirt ops is used by Xen PV guests only. Add a new
config option PARAVIRT_XXL which is selected by XEN_PV. Later we can
put the Xen PV only paravirt ops under the PARACVIRT_XXL umbrella.
