KVM: PPC: Add feature bitmap for magic page
We will soon add SR PV support to the shared page, so we need some infrastructure that allows the guest to query for features KVM exports. This patch adds a second return value to the magic mapping that indicated to the guest which features are available. Signed-off-by: Alexander Graf <agraf@suse.de>
