Subject: [PATCH 5/7] cirrus: stop passing around dst pointers in the blitter

RH-Author: Gerd Hoffmann <kraxel@redhat.com>

Patchwork-id: 74421
O-Subject: [RHEL-7.4 qemu-kvm PATCH 5/7] cirrus: stop passing around dst pointers in the blitter
Bugzilla: 1430059
RH-Acked-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
RH-Acked-by: Laurent Vivier <lvivier@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>

Instead pass around the address (aka offset into vga memory).  Calculate
the pointer in the rop_* functions, after applying the mask to the
address, to make sure the address stays within the valid range.
