Haozhong Zhang 084140bd49 exec: fix access to ram_list.dirty_memory when sync dirty bitmap ... In cpu_physical_memory_sync_dirty_bitmap(rb, start, ...), the 2nd argument 'start' is relative to the start of the ramblock 'rb'. When it's used to access the dirty memory bitmap of ram_list (i.e. ram_list.dirty_memory[DIRTY_MEMORY_MIGRATION]->blocks[]), an offset to the start of all RAM (i.e. rb->offset) should be added to it, which has however been missed since c/s 6b6712efcc. For a ramblock of host memory backend whose offset is not zero, cpu_physical_memory_sync_dirty_bitmap() synchronizes the incorrect part of the dirty memory bitmap of ram_list to the per ramblock dirty bitmap. As a result, a guest with host memory backend may crash after migration. Fix it by adding the offset of ramblock when accessing the dirty memory bitmap of ram_list in cpu_physical_memory_sync_dirty_bitmap().
