That's why we are shadowing GPU MMU translation tables in xen heap.
And this is leaded us to need of [PATCH RFC 18/18] arm: Add ability to
allocate Xen heap in lowmem.
Patche for GPU MMU shadowing is not published yet, I still have to
check if it lacks of proprietary information.
I would rather delay any review on patches required (such as patch #18)
for GPU MMU shadowing until you post the new series.
