[Qemu-devel] [PATCH v2] pc: add 1.8 machine type

["Michael S. Tsirkin" <mst@redhat.com>]

Several changes that affect compatibility between 1.8 and 1.7 are
already planned, so we need pc compat structures in place.

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Changes from v1:
    make 1.6 call 1.7 as suggested by Paolo
