KVM: PPC: Add hidden flag for paired singles
The Gekko implements an extension called paired singles. When the guest wants to use that extension, we need to make sure we're not running the host FPU, because all FPU instructions need to get emulated to accomodate for additional operations that occur. This patch adds an hflag to track if we're in paired single mode or not. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
