ARM/aarch64 are easy to fix because they already have to pass a machine type by hand. Just guard the tests with a check that the machine actually exists.

|
* prove data prior to the marker has been transferred *AND*
|
|
* also prove this transferred data is dirty again.
|

*
|

* Before migration starts, we write a 64-bit magic marker
|
|
* into a fixed location in the src VM RAM.
|

*
|
|
* Then watch dst memory until the marker appears. This is
|
|
* proof that start_address -> MAGIC_OFFSET_BASE has been
|
|
* transferred.
|
|
*
|
|
* Finally we go back to the source and read a byte just
|
|
* before the marker until we see it flip in value. This
|
|
* is proof that start_address -> MAGIC_OFFSET_BASE
|
|
* is now dirty again.
|
|
*
|
|
* IOW, we're guaranteed at least a 2nd migration pass
|
