[Qemu-devel] [PATCH] Fix wrong region_offset when overlaying a page with another |

cpu_register_physical_memory_log() does not update region_offset
if a page was previously registered for the same address. This
could cause mmio accesses going to the wrong place, by using the
old region_offset.

Once qemu-test is merged, remind me to post a testlet for this.
