* remotes/mcayland/tags/qemu-sparc-signed:
  tcx: switch to load_image_mr() and remove prom_addr hack
  tcx: use tcx_set_dirty() for accelerated ops
  tcx: remove primitives for non-32-bit surfaces
  tcx: remove TARGET_PAGE_SIZE from tcx24_update_display()
  tcx: remove TARGET_PAGE_SIZE from tcx_update_display()
  tcx: remove page24 and cpage from tcx24_update_display()
  tcx: alter tcx24_reset_dirty() to accept address and length parameters
  tcx: alter tcx24_check_dirty() to accept address and length parameters
  tcx: ensure tcx_set_dirty() also invalidates the 24-bit plane and cplane
  tcx: alter tcx_set_dirty() to accept address and length parameters
  cg3: switch to load_image_mr() and remove prom-addr hack
  cg3: fix up size parameter for memory_region_get_dirty()
  cg3: remove TARGET_PAGE_SIZE rounding on dirty page detection
