Subject: [PATCH] vga: fix display update region calculation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

vga display update mis-calculated the region for the dirty bitmap
snapshot in case the scanlines are padded.  This can triggere an
assert in cpu_physical_memory_snapshot_get_dirty().
