Subject: [PATCH 08/16] don't use a 32-bit bit type as offset argument.

In the call path of kvm_get_dirty_pages_log_range(),
its caller kvm_get_dirty_bitmap_cb() passes the
target_phys_addr_t both as start_addr and the offset.
So, using int will make dirty tracking over 4G fail
completely.

Of course we should be using qemu types in
here, so please don't get me started on this. The whole
file is wrong already ;)
